[0031] In the description of this utility model, references to terms such as "one embodiment," "some alternative implementations," or "some optional embodiments," 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 this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] Please see Figure 1 One embodiment of this utility model provides a fresh air module for a window-type fresh air unit, including: a side shell 10, two end seals 20, a plurality of fresh air fans 30 and a filter assembly 40;

[0033] The side shell 10 extends along a preset direction, and both ends of the side shell 10 in the preset direction are provided with ports 11;

[0034] Two end seals 20 are respectively disposed at both ends of the side shell 10 in a preset direction and corresponding to the closed port 11. At least one end seal 20 is provided with a fastener 21 for assembly with the body of the window-type fresh air unit. The side shell 10 and the end seals 20 surround to form a fresh air cavity 50, which has a fresh air inlet 51 and a fresh air outlet 52. In this embodiment, the fresh air inlet 51 and the fresh air outlet 52 are disposed on the side shell 10, and both end seals 20 are provided with fasteners 21.

[0035] The side shell 10 can be manufactured using a profile extrusion process, and the required length can be cut according to actual needs. The cut length does not affect the structure of the end of the side shell 10, so the end cap 20 can match side shells 10 of different lengths. Therefore, there is no need to change the structure of the end cap 20 and perform multiple mold openings. Since the fastener 21 is arranged on the end cap 20, it is not affected by the length of the side shell 10 and does not need to change its structure, which helps to reduce costs.

[0036] The fresh air fan 30 is installed inside the fresh air chamber 50. When there are multiple fresh air fans 30, they are arranged sequentially along a preset direction, which facilitates the arrangement of each fresh air fan 30 while meeting the air volume requirements. The number of fresh air fans 30 and the length of different fresh air fans 30 will affect the required length of the side shell 10. Preferably, the fresh air fan 30 is a centrifugal fan with a relatively high air pressure, which allows the air to pass stably through the filter assembly 40.

[0037] The filter assembly 40 is disposed within the fresh air chamber 50, located between the fresh air inlet 51 and the fresh air fan 30. The fresh air inlet 51 connects to the outside, while the fresh air outlet 52 connects to the inside. Outdoor air enters the fresh air chamber 50 through the fresh air inlet 51, then passes sequentially through the filter assembly 40 and the fresh air fan 30, and finally exits from the fresh air outlet 52. The filter assembly 40 filters impurities from the outdoor air, purifies the air, and improves the indoor air quality. The filter assembly 40 can be a pre-filter, medium-efficiency filter, or similar, and is not limited to this example.

[0038] In some alternative implementations, the fresh air module of the window-type fresh air unit also includes a damper assembly 60, which is located at the fresh air inlet 51 and is used to open and close the fresh air inlet 51. This allows the fresh air inlet 51 to be closed when the fresh air function is not in use, preventing outdoor dust, insects, and other pollutants from entering the fresh air chamber 50.

[0039] The specific structure of the damper assembly 60 can be selected according to actual needs. For example, in some optional embodiments, the fresh air chamber 50 has multiple fresh air inlets 51, which are arranged sequentially along a preset direction. The design of multiple fresh air inlets 51 is beneficial to increase the air volume while avoiding the situation where the structural strength of the side shell 10 is insufficient due to the excessive area of ​​a single fresh air inlet 51. The damper assembly 60 includes a damper plate 61 and a damper drive module 62. The damper plate 61 is provided with multiple ventilation openings 611. The damper plate 61 is movably disposed within the fresh air cavity 50. The damper drive module 62 is driven and connected to the damper plate 61. Under the drive of the damper drive module 62, the damper plate 61 can move relative to the fresh air inlet 51 to an open or closed position. When the damper plate 61 is in the open position, the fresh air inlet 51 communicates with the interior of the fresh air cavity 50 through the aforementioned ventilation opening 611. When the damper plate 61 is in the closed position, the damper plate 61 closes the fresh air inlet 51, thereby preventing outdoor airflow, dust, insects, etc., from entering the fresh air cavity 50 through the fresh air inlet 51. Of course, the damper assembly 60 can also adopt other structures. For example, the damper assembly 60 includes a rotating plate and a rotating drive motor. The rotating plate is rotatably engaged with the side shell 10, and the rotation realizes the opening and closing of the fresh air inlet 51.

[0040] In some optional embodiments, a guide groove 53 extending in a preset direction is provided in the fresh air cavity 50. The damper plate 61 is slidably engaged with the guide groove 53, so that the damper plate 61 can move along the preset direction. The damper drive module 62 includes a damper drive motor 621 and a crank 622. A connecting groove 612 is provided on the damper plate 61. The extension direction of the connecting groove 612 is not parallel to the preset direction. The damper drive motor 621 is driven to one end of the crank 622. The other end of the crank 622 is rotatably connected to the connecting groove 612 and can slide along the connecting groove 612. The damper drive motor 621 drives the crank 622 to rotate, so that the crank 622 slides along the connecting groove 612. When the crank 622 slides along the connecting groove 612, it will drive the damper plate 61 to move along the guide groove 53, thereby realizing the opening and closing of the fresh air outlet 52 by the damper plate 61. Of course, the structure of the air valve drive module 62 is not limited to this. Those skilled in the art can also choose other suitable structures based on the teachings of this utility model. For example, the air valve drive module 62 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. The specific installation method with the air valve plate 61 is a technology known to those skilled in the art and will not be described in detail here.

[0041] In some optional embodiments, a plurality of support frames 54 are provided inside the fresh air cavity 50. The support frames 54 are arranged sequentially along a preset direction, and the filter assembly 40 is mounted on the support frame 54. A preset distance is maintained between the side of the filter assembly 40 facing the fresh air inlet 51 and the fresh air inlet 51, creating a buffer and pressure-equalizing space between the side of the filter assembly 40 facing the fresh air inlet 51 and the inner wall of the fresh air cavity 50 near the fresh air inlet 51. This allows air to pass evenly through all positions of the filter assembly 40, preventing the fresh air inlet 51 from adhering to the filter assembly 40 and preventing air from immediately entering the filter assembly 40 after passing through the fresh air inlet 51, thus avoiding air only passing through a localized area of ​​the filter assembly 40 and affecting the filtration effect and airflow rate. When a damper assembly 60 is provided, the damper assembly 60 is positioned between the side of the filter assembly 40 facing the fresh air inlet 51 and the fresh air inlet 51. Maintaining a preset distance between the filter assembly 40 and the fresh air inlet 51 allows sufficient space for the installation of the damper assembly 60.

[0042] In some optional embodiments, the fresh air cavity 50 is provided with a plurality of limiting grooves 55 extending in a preset direction, and the support frame 54 is formed with a sliding part 541. The sliding part 541 slides in cooperation with the limiting grooves 55. Since the side shell 10 needs to be adjusted in length according to actual needs, and the length of the filter assembly 40 also needs to be adjusted accordingly, in order to facilitate the stable assembly of the filter assembly 40, the support frame 54 can adjust its position relative to the side shell 10 along the limiting grooves 55, thereby adapting to support filter assemblies 40 of different lengths.

[0043] In some optional embodiments, the support frame 54 has a support portion 542 and an end limiting portion 543. Multiple support frames 54 are respectively disposed at both ends of the filter assembly 40. The support portion 542 abuts against the side of the filter assembly 40 facing the fresh air inlet 51. The end limiting portion 543 is matched with the end of the filter assembly 40 for limiting. The support portion 542 supports the filter assembly 40 on one side, thereby preventing the filter assembly 40 from tilting towards the fresh air inlet 51. The end limiting portion 543 can prevent the filter assembly 40 from shifting position along a preset direction. By limiting and supporting the filter assembly 40 in multiple directions, the filter assembly 40 can be installed stably.

[0044] In some optional embodiments, the side shell 10 is provided with a disassembly port 12 communicating with the fresh air cavity 50. The filter assembly 40 is detachably installed into the fresh air cavity 50 through the disassembly port 12. The filter assembly 40 can be inserted into the fresh air cavity 50 through the disassembly port 12, and can also be removed from the fresh air cavity 50 through the disassembly port 12, thereby facilitating the cleaning and replacement of the filter assembly 40. When the support frame 54 has a support portion 542 and an end limiting portion 543, the support portion 542 and the end limiting portion 543 can also guide the movement of the filter assembly 40 during the insertion of the filter assembly 40 into the fresh air cavity 50, so that the filter assembly 40 can be easily disassembled and installed. In addition, in this embodiment, the filter assembly 40 is also provided with a handle portion 41 extending out of the disassembly port 12, which makes it convenient for the user to grab the filter assembly 40 and pull the filter assembly 40 out of the fresh air cavity 50.

[0045] In some alternative embodiments, at least one fastener 21 or at least one end cap 20 is provided with an electrical connector (not shown), which can be electrically connected to the air valve drive motor 621 of the fresh air fan 30 and the air valve assembly 60, respectively. When the fresh air module of the window-type fresh air unit is assembled onto the body of the window-type fresh air unit, the fastener 21 is fixed to the body of the window-type fresh air unit, and the electrical connector is plugged into the socket or plug of the window-type fresh air unit, thereby enabling the fresh air fan 30 and the air valve assembly 60 to be electrically connected to the body of the window-type fresh air unit, reducing the trouble of wiring, achieving a plug-and-play effect, and facilitating installation. In this embodiment, the electrical connector is mounted on the fixing member 21. Since the fixing member 21 is directly connected to the main body of the window-type fresh air unit, the structure near the fixing member 21 is the most stable, allowing the electrical connector to be inserted more stably. The electrical connector can be selected to be mounted on one side of the fixing member 21 according to the specific structure of the window-type fresh air unit, so that the electrical connector can be easily inserted into the corresponding structure when the fixing member 21 is connected to the main body of the window-type fresh air unit. In addition, in this embodiment, a circuit board is also mounted on the fixing member 21, and the fresh air fan 30 and the air valve assembly 60 are connected to the electrical connector through the circuit board. The circuit board can be equipped with drive circuits, control circuits, etc., to facilitate power supply and control of the fresh air fan 30 and the air valve assembly 60. Moreover, the fact that the circuit board is on the fixing member 21 rather than inside the fresh air cavity 50 also facilitates maintenance.

[0046] In some optional embodiments, the side shell 10 includes a first shell 13 and a second shell 14 connected to each other. Both the first shell 13 and the second shell 14 extend in a predetermined direction. A port 11 is formed between the first shell 13 and the second shell 14. Two end seals 20 are respectively connected to the two ends of the first shell 13 in the predetermined direction and to the two ends of the second shell 14 in the predetermined direction. Dividing the side shell 10 into two parts, the first shell 13 and the second shell 14, helps to reduce the molding difficulty and facilitates the extrusion molding of the first shell 13 and the second shell 14. Moreover, dividing it into two parts allows for the pre-installation of the structure to be installed into the fresh air cavity 50 before connecting the first shell 13 and the second shell 14. This is especially convenient when the side shell 10 is relatively long, making it easier to assemble the internal structure of the fresh air cavity 50.

[0047] In some optional embodiments, the side shell 10 further includes a support partition 15 extending along a predetermined direction. The support partition 15 is disposed between the first shell 13 and the second shell 14, and is connected to the first shell 13 and / or the second shell 14. The support partition 15 can support the first shell 13 and the second shell 14, thereby preventing the first shell 13 and the second shell 14 from bending and deforming, improving the overall structural strength, and simplifying the structure of the first shell 13 and the second shell 14, reducing the molding difficulty. The support partition 15 is located inside the fresh air cavity 50 and divides the fresh air cavity 50 into a first air cavity 56 and a second air cavity 57. The cavity 57 has several connecting ports 151 on the supporting partition 15, connecting the first air cavity 56 and the second air cavity 57. A filter assembly 40 is disposed within the first air cavity 56, located between the connecting ports 151 and the fresh air inlet 51. A fresh air fan 30 is disposed within the second air cavity 57, with its inlet connected to the connecting port 151 and its outlet connected to the fresh air outlet 52. When the fresh air fan 30 is started, it draws air from the fresh air inlet 51 into the first air cavity 56, then through the filter assembly 40 and into the second air cavity 57 via the connecting ports 151, finally exiting from the fresh air outlet 52. The number of connecting ports 151 can be designed according to actual needs; each connecting port 151 can connect to multiple fresh air fans 30 simultaneously or to a one-to-one correspondence with a fresh air fan 30.

[0048] The supporting partition 15 can also be manufactured using a profile extrusion process. The first housing 13, the second housing 14, and the supporting partition 15 can all be cut to appropriate lengths according to actual needs. The supporting partition 15 can be extruded separately; or, the supporting partition 15 can be formed on the first housing 13 or the second housing 14, reducing the connection structure and making production and assembly easier. Of course, the supporting partition 15 can also be connected to the first housing 13 and / or the second housing 14 by welding, adhesive bonding, thread locking, etc. In this embodiment, the supporting partition 15 and the first housing 13 are extruded together, making the supporting partition 15 and the first housing 13 integrally formed, reducing the connection structure and making production and assembly easier. The first air cavity 56 is formed between the supporting partition 15, the first housing 13, and the two end seals 20, while the second air cavity 57 is formed between the supporting partition 15, the second housing 14, and the two end seals 20.

[0049] The connection method of the first housing 13 and the second housing 14 can be selected according to actual needs. For example, in some optional embodiments, the first housing 13 is provided with locking parts 131 on both sides, and the second housing 14 is provided with locking grooves 141 on both sides. The locking parts 131 are locked and engaged with the locking grooves 141, thereby realizing the connection of the first housing 13 and the second housing 14. Of course, the connection method of the first housing 13 and the second housing 14 is not limited to this. Those skilled in the art can also select other suitable connection methods according to the teachings of this utility model. For example, the first housing 13 and the second housing 14 can be connected by welding, adhesive bonding, thread locking, etc.

[0050] The aforementioned fresh air module for a window-type fresh air system can be applied to a window-type fresh air system, which includes: the aforementioned fresh air module for a window-type fresh air system.
