[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] A greenhouse air conditioner is a specialized air conditioning system designed for agricultural planting environments. It primarily regulates environmental parameters such as temperature, humidity, and airflow within greenhouses to ensure plants grow under optimal conditions. Some existing greenhouse air conditioners can circulate air within the greenhouse for temperature control. They also feature a fresh air damper mechanism, which includes a damper plate and a actuator. The actuator opens or closes the air intake vents on the housing. When the greenhouse air conditioner is in fresh air mode, the damper plate opens the intake vents, allowing fresh outdoor air to be drawn in and circulated into the room. When the greenhouse air conditioner is in indoor air circulation mode, the damper plate needs to be closed to prevent outside air from entering. However, current fresh air damper mechanisms still exhibit some air leakage when the damper plate is closed, indicating insufficient sealing.

[0029] Reference Figures 1 to 3 The novel air damper mechanism of this utility model includes a housing 100, a damper plate 200, a driver 300, and a sealing reinforcement 400. The housing 100 is provided with an air inlet 101; the damper plate 200 is rotatably disposed on the housing 100 and can rotate to an open position and a closed position. In the open position, the air inlet 101 is open, and in the closed position, the damper plate 200 closes the air inlet 101; the driver 300 is disposed on the housing 100 and is used to drive the damper plate 200 to rotate; the sealing reinforcement 400 is disposed on the damper plate 200 or the housing 100. In the closed position, the sealing reinforcement 400 can apply a force to bring the damper plate 200 closer to the air inlet 101.

[0030] When the actuator 300 drives the damper plate 200 to the open position, it opens the air inlet 101, allowing outdoor air to enter the housing 100 through the air inlet 101 and eventually enter the room, thus realizing the fresh air function. When the actuator 300 drives the damper plate 200 to close the air inlet 101, the sealing reinforcement 400 can apply a force to bring the damper plate 200 closer to the air inlet 101, so that the damper plate 200 presses further against the housing 100 to seal the air inlet 101, thereby improving the sealing effect when the damper plate 200 is closed and reducing a small amount of air leakage.

[0031] In the embodiments, reference is made to Figure 1 The housing 100 is provided with an iron part, and the sealing reinforcement 400 is a magnet. The magnet is connected to the damper plate 200. When the damper plate 200 is in the closed position, the magnet and the iron part are opposite to each other and magnetically attracted.

[0032] When the damper plate 200 is in the closed position, the magnet attracts the iron part, providing a force to the damper plate 200 to approach the air inlet 101, allowing the damper plate 200 to press firmly against the housing 100. The sealing reinforcement 400 has a relatively simple structure and is easy to implement. When the air inlet 101 needs to be opened, the driver 300 drives the damper plate 200 to rotate, overcoming the magnetic attraction between the magnet and the iron part to open the air inlet 101.

[0033] Specifically, the entire casing 100 can be made of iron, meaning the iron part is the casing 100 itself. It is conceivable that in some other embodiments, the casing 100 may also have an iron block placed near the air inlet 101, the iron block being used to attract the magnet.

[0034] In the embodiments, reference is made to Figure 1 One end of the damper plate 200 is rotatably connected to the housing 100, and a magnet is connected to the opposite end of the damper plate 200. Normally, the end of the damper plate 200 furthest from the rotation axis is difficult to press firmly against the housing 100, easily leading to air leakage. Therefore, a magnet is installed at the end of the damper plate 200 furthest from the rotation axis. When the damper plate 200 is closed, the magnet can generate a strong magnetic attraction force on this end, allowing it to press firmly against the housing 100, thereby maximizing the sealing effect of the damper plate 200 and reducing the risk of air leakage.

[0035] In the embodiments, reference is made to Figure 1 and Figure 2 Multiple air inlets 101 are arranged in an array in the vertical plane, and at least two sealing reinforcements 400 are arranged at intervals along the periphery of the damper plate 200. The multiple air inlets 101, when open, improve air intake efficiency; the arrangement of the multiple sealing reinforcements 400, when the damper plate 200 is in the closed position, ensures that all edges of the damper plate 200 are firmly against the housing 100, achieving a better sealing effect.

[0036] Specifically, the number of air inlets 101 can be two or more, and the number of sealing reinforcements 400, i.e., magnets, can be two or more. Those skilled in the art can choose according to actual needs.

[0037] It is conceivable that in some other embodiments, the magnet may also be disposed on the housing 100, and the corresponding iron part may be disposed on the damper plate 200.

[0038] It is conceivable that in other embodiments, the sealing reinforcement 400 may also be, for example, a torsion spring, which continuously applies a force to the damper 200 toward the air inlet 101 when the damper 200 is in the closed position, causing the damper 200 to press against the housing 100.

[0039] In the embodiments, reference is made to Figure 3 A sealing strip mounting groove 210 is provided on the side of the damper plate 200 near the air inlet 101, and the sealing strip mounting groove 210 is arranged around the air inlet 101. The sealing strip mounting groove 210 can be used to install a positioning sealing strip. When the damper plate 200 closes the air inlet 101, the sealing strip surrounds the outside of the air inlet 101, which can form a seal between the damper plate 200 and the housing 100, reducing the risk of air leakage between the damper plate 200 and the housing 100.

[0040] In the embodiments, reference is made to Figure 1 and Figure 3 The driver 300 is configured as a motor, which has an output shaft 310. The output shaft 310 is arranged along the rotation axis of the damper plate 200. The output shaft 310 is connected to one end of the damper plate 200 along its rotation axis. The other end of the damper plate 200 along its rotation axis is provided with a pivot 220, which is pivotally connected to the housing 100.

[0041] One end of the damper plate 200 rotates relative to the housing 100 via the output shaft 310 of the motor, and the other end rotates relative to the housing 100 via a pivot 220. At the same time, the motor can directly drive the damper plate 200 to rotate via the output shaft 310, resulting in a simple and compact structure.

[0042] It is conceivable that in other embodiments, the damper plate 200 may be pivotally connected to the housing 100 via a pivot 220, and the driver 300 may be configured as a motor and a transmission gear set to drive the damper plate 200 to rotate; or the driver 300 may be a rotary cylinder to drive the damper plate 200 to rotate; or the driver 300 may be an electric push rod, one end of which is pivotally connected to the housing 100 and the other end of which is pivotally connected to the damper plate 200, and the damper plate 200 is driven to rotate by the extension and retraction of the electric push rod.

[0043] In the embodiments, reference is made to Figure 1 and Figure 3 The housing 100 includes a shell plate 110, a first mounting base 120, and a second mounting base 130. Both the first mounting base 120 and the second mounting base 130 are mounted on the shell plate 110. The damper plate 200 and the air inlet 101 are located between the first mounting base 120 and the second mounting base 130. The driver 300 is mounted on the first mounting base 120. The second mounting base 130 is provided with a pivot hole 131, and a pivot 220 is rotatably connected to the pivot hole 131. The housing 100 described above is advantageous for the production and assembly process, has a simple structure, and is easy to implement.

[0044] Specifically, the first mounting base 120 is integrally formed with a first pin portion 121, and the first mounting base 120 is inserted into the shell plate 110 through the first pin portion 121. The first mounting base 120 is fixed to the shell plate 110 by screws. The second mounting base 130 is integrally formed with a second pin portion 132, and the second mounting base 130 is inserted into the shell plate 110 through the second pin portion 132. The second mounting base 130 is fixed to the shell plate 110 by screws.

[0045] Specifically, the first mounting base 120 is provided with a mounting groove, and the motor part is located in the mounting groove. There is a gap between the motor and the groove wall, and the motor is fastened to the first mounting base 120 by screws. The gap between the motor and the groove wall facilitates smooth installation of the motor and also helps with heat dissipation.

[0046] In this embodiment, a position sensor and a controller are also included. The position sensor is disposed in the housing 100 and is used to detect the position of the damper plate 200. The controller is disposed in the housing 100 and is electrically connected to the position sensor and the driver 300. The position sensor can detect the position of the damper plate 200, so that when the damper plate 200 rotates to the correct position, the motor can be stopped at the current position, avoiding the risk of motor stalling due to excessive rotation of the damper plate 200.

[0047] Specifically, the position sensor can be an inductive, capacitive, or Hall effect sensor to detect the position of the damper plate 200. The controller can be a circuit board with control circuitry, a microcontroller, or a PLC.

[0048] In the embodiments, reference is made to Figure 1 A reinforcing rib 230 is provided on the side of the damper plate 200 opposite to the air inlet 101. The reinforcing rib 230 can enhance the structural strength of the damper plate 200 and reduce the risk of cracking and damage to the damper plate 200 due to excessive wind force or excessive air pressure difference.

[0049] This utility model also discloses a planting air conditioner that adopts the above-mentioned fresh air damper mechanism. Because of the adoption of the above-mentioned fresh air damper mechanism, the risk of air leakage when the fresh air function is turned off can be reduced.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
