[0002] A greenhouse is a device for cultivating crops in a relatively closed environment. The relatively closed environment makes it easier to control the environment inside the greenhouse that is suitable for the growth of crops. However, greenhouses have the problem of poor ventilation in a relatively closed environment, and it is difficult to adjust the temperature and humidity inside the greenhouse. Therefore, exhaust devices are usually equipped to adjust the exhaust size according to the temperature and humidity conditions. A protective net is generally set in the exhaust device to intercept debris in the air and prevent it from damaging the fan.

[0003] After searching, a Chinese patent with announcement number CN217657376U discloses an exhaust device for greenhouse temperature and humidity control, including a fixed pipe with multiple air vents in the middle. The device facilitates the circulation of wind inside the greenhouse, improves the wind transmission effect, improves the regulation effect, and facilitates the handling of debris in the ventilation area.

[0004] However, the inventor discovered the following problems in the prior art during the process of implementing the utility model:

[0005] For example, in the prior art, debris is mainly intercepted by an isolation net, which allows the debris to enter a temporary storage box for storage, and the purpose of use is achieved by regularly cleaning the debris in the temporary storage box. However, the isolation net is prone to clogging when intercepting the debris. When the isolation net is clogged, the device cannot be used normally, and the prior art also does not provide a structure for cleaning the isolation net, so it can only be disassembled and cleaned, which is a cumbersome operation.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] See also Figure 1-Figure 5 An exhaust device for controlling temperature and humidity in a greenhouse comprises a first exhaust duct 1, a second exhaust duct 2 and a connecting pipe 3. The adjacent ends of the first exhaust duct 1 and the second exhaust duct 2 are detachably connected to the two sides of the connecting pipe 3. An isolation net 4 is arranged inside the connecting pipe 3 relative to the first exhaust duct 1. A rotating assembly 5 is arranged inside the connecting pipe 3 relative to the isolation net 4. A cleaning assembly 6 is arranged on the connecting pipe 3. A collecting assembly 7 located directly below a spray plate 601 is arranged at the bottom of the connecting pipe 3. A battery 8 and a controller 9 are arranged on the connecting pipe 3.

[0034] When exhausting, by setting the isolation net 4, impurities in the air can be filtered, by setting the rotating component 5, the position of the isolation net 4 can be replaced, by setting the cleaning component 6, the debris on the isolation net 4 can be cleaned, and by setting the collecting component 7, the cleaning water can be automatically collected and discharged, so that the debris adhered to the isolation net 4 can be cleaned without disassembling and cleaning it, avoiding the need to disassemble the isolation net 4 regularly. By setting the battery 8 and the controller 9, it can play the role of energy supply and control.

[0035] Preferably, see Figure 1-Figure 3 , the isolation net 4 is embedded and installed on the installation frame 501, and one end of the first exhaust duct 1 is in contact with the isolation net 4; the rotating component 5 includes an installation frame 501 that is arranged obliquely, and a driving component 502 for driving the installation frame 501, the driving component 502 includes a rotating rod 5021 that is rotatably connected to the connecting pipe 3, a connecting sleeve 5023 that is fixedly sleeved with the rotating rod 5021, and an L-shaped connecting plate 5024 that is connected to the installation frame 501 and the connecting sleeve 5023, a motor 5022 is fixedly installed on the top of the connecting pipe 3 relative to the position of the rotating rod 5021, the number of isolation nets 4 and the number of installation frames 501 are both two, and the two isolation nets 4 and the two installation frames 501 are equidistantly arranged on the same circle with the axis of the rotating rod 5021 as the center.

[0036] When exhausting, by setting the isolation net 4, impurities in the air can be filtered. When there are too many sundries adhering to the isolation net 4 at the position of the connecting pipe 3 and affecting the exhaust, the motor 5022 drives the rotating rod 5021 to rotate, and under the linkage of the connecting sleeve 5023 and the L-shaped connecting plate 5024, the installation frame 501 can be rotated, thereby driving the isolation net 4 to rotate. By rotating 180 degrees, the positions of the two isolation nets 4 can be interchanged, and then the exhaust effect can be ensured by placing the new isolation net 4 in contact with the first exhaust pipe 1.

[0037] Among them, the isolation net 4 is set in a semicircular shape on one side close to the first exhaust duct 1, and a matching semicircular groove is opened at one end of the first exhaust duct 1 relative to the position of the isolation net. In this way, the isolation net 4 can be prevented from being obstructed by the first exhaust duct 1 when rotating, and at the same time, it can also ensure that the isolation net 4 can fit tightly with the first exhaust duct 1 after rotation.

[0038] For further information, see Figure 4 The cleaning component 6 includes a spray plate 601 arranged at the top end of the connecting pipe 3, a water tank 603 installed on the front surface of the connecting pipe 3, a water pump 604 installed on the water tank 603, and a water supply pipe 602 for connecting the water pump 604 and the spray plate 601. A plurality of water outlet grooves are provided on the lower surface of the spray plate 601, and a receiving groove is provided on the top end of the plurality of water outlet grooves. One end of the water supply pipe 602 away from the water tank 603 passes through the interior of the receiving groove; the orthographic projection area of ​​the isolation net 4 when viewed from above is adapted to the area of ​​the spray plate 601 when viewed from above.

[0039] After the positions of the two isolation nets 4 are interchanged, the isolation net 4 covered with debris is located directly below the cleaning assembly 6. At this time, the water pump 604 is turned on, so that the cleaning water in the water tank 603 can be introduced into the inside of the spray plate 601 through the water supply pipe 602, and then sprayed onto the isolation net 4 covered with debris through the water outlet trough, so that the isolation net 4 covered with debris can be cleaned and the debris attached thereto can be cleaned;

[0040] In addition, since the installation frame 501 is inclined, the isolation net 4 installed on the installation frame 501 is also inclined. By slanting the isolation net 4, during cleaning, excess cleaning water at a higher position of the isolation net 4 can flow along its downward slope, thereby achieving the effect of secondary cleaning.

[0041] For further information, see Figure 2 and Figure 5 The collecting assembly 7 includes a collecting box 701 embedded in the bottom of the connecting pipe 3 and a discharge pipe 702 connected to the bottom of the collecting box 701 . A liquid level sensor 703 is fixedly mounted on the inner wall of the collecting box 701 , and a solenoid valve 704 is installed on the discharge pipe 702 .

[0042] The cleaning water after cleaning flows into the collection box 701 for collection. By setting the discharge pipe 702, the collected water can be discharged. By setting the liquid level sensor 703 and the solenoid valve 704, the cleaning water inside the collection box 701 can be discharged uniformly after reaching a certain liquid level height, thereby facilitating the staff to collect it uniformly.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
