[0029] This application provides a purification device 100; please refer to [link / reference]. Figure 1 and Figure 2 The purification device 100 includes a housing 1, a static pressure chamber 2, and a fan assembly 3. The static pressure chamber 2 is disposed inside the housing 1. The fan assembly 3 is disposed within the static pressure chamber 2.

[0030] For housing 1 mentioned above, please refer to Figure 3 The housing 1 is provided with a first opening 11 and multiple primary return air inlets 12. The first opening 11 is located at the bottom of the housing 1. The first opening 11 is used to allow airflow to exit the housing 1. The multiple primary return air inlets 12 are located on the side of the housing 1. The primary return air inlets 12 are used to allow airflow to enter the housing 1. The multiple primary return air inlets 12 are used to reduce the noise generated by the fan assembly 3 during the exhaust process.

[0031] For the static pressure chamber 2 mentioned above, please refer to Figure 4 The static pressure chamber 2 is located inside the shell 1. The static pressure chamber 2 is provided with an installation port 21, which is connected to the first opening 11 and the primary return air port 12.

[0032] For the aforementioned fan assembly 3, please refer to Figure 5 The fan assembly 3 includes a fan 31 and a bracket 32. The fan 31 is located at the mounting port 21. The bracket 32 ​​connects the fan 31 and the side of the static pressure chamber 2 facing the first opening 11. Since the purification device 100 is installed from the top or suspended, connecting the bracket 32 ​​to the side of the static pressure chamber 2 facing the first opening 11 facilitates future maintenance and repair.

[0033] In some embodiments, the fan 31 is a backward-curved centrifugal fan.

[0034] The support frame 32 includes a fixing plate 321, a first fixing rod 322, and a second fixing rod 323. The fixing plate 321 is connected to the fan 31. The middle part of the first fixing rod 322 is fixed to the fixing plate 321, and both ends of the first fixing rod 322 are connected to the static pressure box 2. The two ends of the first fixing rod 322 are formed by bending the middle part of the first fixing rod 322. The middle part of the second fixing rod 323 is fixed to the fixing plate 321, and both ends of the second fixing rod 323 are connected to the static pressure box 2. The two ends of the second fixing rod 323 are formed by bending the middle part of the second fixing rod 323. The first fixing rod 322 is exposed between one end and the other end, the second fixing rod 323 is exposed between one end and the other end, the first fixing rod 322 is exposed between one end and the second fixing rod 323, and the first fixing rod 322 is exposed between the other end and the second fixing rod 323. This makes the perimeter of the bracket 32 ​​exposed, that is, the bracket 32 ​​is exposed on all four sides. This reduces the corresponding area between the bracket 32 ​​and the air outlet of the fan 31, increases the airflow area from the air outlet of the fan 31, and thus reduces noise.

[0035] In some embodiments, the cross-sectional shape of the first fixing rod 322 and the cross-sectional shape of the second fixing rod 323 are both circular to reduce the impact force of airflow and thus reduce noise.

[0036] In some embodiments, the ends of the first fixing rod 322 and the ends of the second fixing rod 323 are connected in sequence to form a square, so that the four connection positions of the bracket 32 ​​and the static pressure box 2 are connected in sequence to form a square. Compared with the way that the four connection positions of the U-shaped bracket 32 ​​are connected in sequence to form a rectangle, the connection and fixing effect of this application is better, thereby reducing the vibration of the fan 31.

[0037] In some embodiments, the bracket 32 ​​includes a mounting plate 324, which is fixed to the ends of the first fixing rod 322 and the ends of the second fixing rod 323, and the mounting plate 324 is connected to the static pressure chamber 2.

[0038] In some embodiments, the number of mounting plates 324 is four.

[0039] In some embodiments, the fan assembly 3 includes a mounting base 33, which is disposed at the mounting port 21. The mounting base 33 is connected to the side of the static pressure box 2 facing away from the first opening 11. The mounting base 33 is connected to the mounting plate 324. The fan 31 passes through the mounting port 21 and is connected to the mounting base 33. The mounting base 33 is provided with a second opening 331, which communicates with the primary return air port 12.

[0040] In some embodiments, the mounting base 33 is provided with a plurality of screw holes 332, the fan assembly 3 includes a plurality of bolts (not shown), the mounting plate 324 is provided with a plurality of first through holes 3241, and the mounting base 33 is provided with a plurality of screw holes 332. The bolts pass through the first through holes 3241 and are screwed into the screw holes 332. By connecting and fixing the mounting plate 324 to the mounting base 33 with the aforementioned plurality of bolts, the fan 31 is more stably fixed, reducing the vibration of the fan 31.

[0041] It is understood that in some embodiments, the mounting base 33 is not limited to the above structure. The mounting base 33 is provided with a second through hole (not shown), and the fan assembly 3 also includes a plurality of nuts (not shown). The bolt passes through the first through hole 3241 and the second through hole and is screwed onto the nuts.

[0042] In some embodiments, there are multiple static pressure chambers 2 and multiple fan assemblies 3, with one fan assembly 3 disposed in one static pressure chamber 2. Compared to a structure in which multiple fan assemblies 3 are disposed in one static pressure chamber 2 and separated by partitions, when multiple fan assemblies 3 are disposed in one static pressure chamber 2, the static pressure chamber 2 will vibrate due to the vibration generated by the fan 31 during operation. When multiple fans 31 are running, the resonant frequencies will be inconsistent, resulting in noise. However, this application avoids the vibration generated by multiple fans 31 acting on the same static pressure chamber 2 by disposing of one fan assembly 3 in one static pressure chamber 2, thereby reducing noise. Furthermore, when multiple fan assemblies 3 are installed in a static pressure box 2, and the spaces on both sides of the partition are connected, when multiple fans 31 are running, the airflow is thrown out along the periphery of the air outlet of the fan 31. Because the frequency and direction of the airflow thrown out by multiple fans 31 are inconsistent, mixed flow occurs, resulting in wind noise. However, this application installs a fan assembly 3 in a static pressure box 2, so that two adjacent static pressure boxes 2 are separated, preventing the airflow output by different fans 31 from mixing, thereby reducing noise.

[0043] In some embodiments, the purification device 100 includes a high-efficiency filter disposed at the first opening 11 of the housing 1, so that the airflow is filtered by the high-efficiency filter and flows into the room.

[0044] In some embodiments, the purification device 100 further includes a pre-filter disposed in the housing 1, such that the airflow entering the housing 1 is filtered by the pre-filter before passing through the fan 31.

[0045] In some embodiments, the purification device 100 further includes a differential pressure gauge connected to the housing 1.

[0046] In this embodiment of the invention, the purification device 100 includes a housing 1, a static pressure chamber 2, and a fan assembly 3. The static pressure chamber 2 is disposed within the housing 1 and has an installation port 21. The fan assembly 3 includes a fan 31 and a bracket 32. The fan 31 is disposed at the installation port 21, and the bracket 32 ​​is connected to the fan 31 and the static pressure chamber 2. The periphery of the bracket 32 ​​is exposed. Because the periphery of the bracket 32 ​​is exposed, the corresponding area between the bracket 32 ​​and the air outlet of the fan 31 is reduced, increasing the airflow area from the air outlet of the fan 31, thereby reducing noise.
