Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a greenhouse air circulation device. Background Technology

[0002] Greenhouse cultivation of seedlings can improve their growth rate and quality, effectively prevent pests and diseases, and enhance fruit quality. However, excessively high humidity is a major obstacle to seedling growth in greenhouses. Excessive humidity inhibits transpiration, thus affecting normal growth. An effective dehumidification method is to circulate air between the indoor and outdoor areas, exchanging air and dehumidifying the greenhouse. Therefore, a greenhouse air circulation system is necessary.

[0003] Regarding the aforementioned technologies, the applicant believes that when a greenhouse air circulation device is in operation, an intake fan continuously draws external air into the greenhouse through an intake pipe, followed by an exhaust fan that works in conjunction to orderly expel the indoor air, achieving efficient ventilation. However, during this process, the external air carries harmful impurities such as insect eggs, pathogen spores, and dust, and its temperature is often significantly lower than that inside the greenhouse. This low-temperature air entering the greenhouse can easily cause a sharp drop in local temperature, potentially damaging delicate plants and increasing the risk of pests and diseases due to the intrusion of harmful impurities, seriously threatening the normal growth and healthy development of the seedlings.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1 to 5 This embodiment provides a technical solution: a greenhouse air circulation device, including an air inlet pipe 1 and a processing mechanism 2. The processing mechanism 2 is disposed inside the air inlet pipe 1. The processing mechanism 2 includes a filter cylinder 203 that runs through the air inlet pipe 1. The filter cylinder 203 can provide load-bearing capacity. The bottom end of the filter cylinder 203 is evenly provided with air inlets 204 to facilitate the entry of external air into the interior of the filter cylinder 203.

[0032] The filter cartridge 203 is provided with a fixing frame 201 on the outside, which can provide load-bearing capacity. Fixing blocks 205 are provided through all four sides of the fixing frame 201. The fixing blocks 205 can easily pass through the interior of the fixing frame 201 and the air inlet pipe 1. A magnet 206 is provided inside the fixing block 205. The magnet 206 is magnetically connected to the air inlet pipe 1. By using the magnetic connection between the magnet 206 inside the fixing block 205 and the air inlet pipe 1, the fixing block 205 can be easily limited.

[0033] A dustproof net 207 is installed at the lower part of the filter cylinder 203. The dustproof net 207 can effectively intercept large dust particles and insect remains in the air. A filter layer 208 is installed at the upper part of the filter cylinder 203. The filter layer 208 is a polytetrafluoroethylene microporous filter with uniform and small pore size. It can accurately filter out small particles such as bacterial spores and dust in the air and also has a good interception effect on insect eggs. It can effectively improve the filtration accuracy and ensure the cleanliness of greenhouse air. Heating tubes 202 are installed at the upper part of both ends of the air inlet pipe 1. The working principle of the heating tube 202 is that the current passes through the internal resistance wire, and the heat generated by the current heating effect is used for heating. It can heat the air inside the heating tube 202. When selecting, the appropriate model should be selected according to the actual needs. There are two sets of heating tubes 202.

[0034] The overall effect of the first embodiment is as follows: The device is installed inside the greenhouse, with the air inlet pipe 1 and exhaust pipe 4 installed outside the greenhouse, and the ventilation pipe 3 installed inside the greenhouse. By inserting the filter cylinder 203 into the air inlet pipe 1, and then inserting the fixing block 205 through the fixing frame 201 into the preset slot inside the air inlet pipe 1, the magnetic connection of the magnet block 206 inside the fixing block 205 with the air inlet pipe 1 can be used to limit the fixing block 205. The filter cylinder 203 can be installed inside the air inlet pipe 1. The dustproof net 207 at the bottom inside the air inlet pipe 1 can effectively intercept large dust particles and insect remains in the air. The filter layer 208 at the top inside the air inlet pipe 1, which is a polytetrafluoroethylene microporous filter, can capture tiny impurities such as bacterial spores and insect eggs. The clean air after double filtration is drawn into the air inlet pipe 1, which can reduce the risk of disease and pest transmission, create a stable growth environment for seedlings, and improve the practicality of the device.

[0035] Example 2

[0036] An air intake fan 5 is installed above the inside of the air intake pipe 1. The working principle of the air intake fan 5 is to use the lift principle in aerodynamics to drive the gas to flow along the axial direction (parallel to the impeller axis) by rotating the blades at high speed, which resemble an air wing. When selecting it, the appropriate model should be selected according to the actual needs. All the components required in the air intake fan 5 are existing technologies and will not be described in detail below.

[0037] One end of the air inlet pipe 1 is equipped with a ventilation pipe 3 to facilitate the delivery of air into the interior of the greenhouse. The bottom of the ventilation pipe 3, near the air inlet pipe 1, is provided with an air outlet 6, and the bottom of the ventilation pipe 3, away from the air inlet pipe 1, is provided with an exhaust outlet 7.

[0038] The effect achieved by the entire embodiment 2 is as follows: by using the operation of the suction fan 5, the filtered air can be drawn into the air inlet pipe 1, and through the ventilation pipe 3, it can be discharged into the interior of the greenhouse through the air outlet 6, thereby reducing the stimulation of external air on the seedlings inside the greenhouse.

[0039] Example 3

[0040] The ventilation pipe 3 is equipped with a control valve 10, which can easily seal the inside of the ventilation pipe 3. An exhaust pipe 4 is provided at one end of the ventilation pipe 3 near the control valve 10. An exhaust fan 9 is provided at the bottom inside the exhaust pipe 4. The exhaust fan 9 works on the same basic principle as the intake fan 5. A filter screen 8 is provided at the bottom inside the exhaust pipe 4.

[0041] The effect achieved by the entire embodiment three is as follows: by using the operation of the exhaust fan 9, the air inside the greenhouse can be drawn in through the exhaust port 7 and then discharged through the exhaust pipe 4, thereby ventilating the greenhouse.

[0042] Working principle: The device is installed inside the greenhouse, with the air inlet pipe 1 and exhaust pipe 4 installed outside the greenhouse and the ventilation pipe 3 installed inside the greenhouse. The filter cylinder 203 is inserted into the air inlet pipe 1, and then the fixing block 205 is inserted into the preset slot inside the air inlet pipe 1 through the fixing frame 201. The magnetic connection between the fixing block 205 and the air inlet pipe 1 is achieved by the magnetic block 206 inside the fixing block 205, which can be easily limited. The filter cylinder 203 can be installed inside the air inlet pipe 1. The dustproof net 207 at the bottom inside the air inlet pipe 1 can effectively intercept large dust particles and insect remains in the air. The filter layer 208 at the top inside the air inlet pipe 1, which is a polytetrafluoroethylene microporous filter, can capture tiny impurities such as bacterial spores and insect eggs in the air. The clean air after double filtration is drawn into the air inlet pipe 1, which can reduce the risk of disease and pest transmission, create a stable growth environment for seedlings, and improve the practicality of the device.

[0043] Secondly, by using the suction fan 5, the filtered air can be drawn into the air inlet pipe 1. By using the heating pipe 202, the air can be heated. The heated air is then transported into the ventilation pipe 3 and discharged into the greenhouse through the air outlet 6, thereby reducing the stimulation of low-temperature air on the seedlings inside the greenhouse.

[0044] Finally, by using the exhaust fan 9, air inside the greenhouse can be drawn in through the exhaust port 7 and then discharged through the exhaust pipe 4, thereby ventilating the greenhouse.
