[0069] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0070] Please also refer to Figures 1-13 This utility model provides some preferred embodiments of a fan installation device and some preferred embodiments of a ventilator.
[0071] like Figure 1 and Figure 2 As shown, the ventilator is cubic in shape. The mounting device for the fan 70 is located inside the ventilator. The mounting device for the fan 70 is used to install the fan 70, which is specifically installed inside the mounting device. The mounting device for the fan 70 includes a bottom structure 10, which is located at the bottom of the ventilator; a middle structure 30, which is connected to the top of the bottom structure 10; and a third vibration damping structure 63, which is connected to the bottom of the middle structure 30 (see [reference]). Figure 3 The third vibration damping structure 63 is located at the bottom of the ventilator, supporting and damping the mounting device of the fan 70. During operation, the fan 70 may vibrate, potentially causing its mounting device to vibrate as well. The third vibration damping structure 63 reduces the transmission of vibration from the fan 70's mounting device to other components of the ventilator. The mounting device of the fan 70 includes a top layer structure 50, which is connected to the top of the middle layer structure 30.
[0072] like Figure 3 As shown, a first sealing structure 20 exists between the bottom layer structure 10 and the middle layer structure 30, which seals the bottom layer structure 10 and the middle layer structure 30. A second sealing structure 40 exists between the middle layer structure 30 and the top layer structure 50 (see...). Figure 2 The second sealing structure 40 achieves a seal between the middle layer structure 30 and the top layer structure 50. During operation, the fan 70 generates noise, which can propagate through the air. The first sealing structure 20 and the second sealing structure 40 seal the mounting of the fan 70, preventing noise from propagating through the gaps between the bottom layer structure 10 and the middle layer structure 30, and between the middle layer structure 30 and the top layer structure 50.
[0073] like Figure 4 and Figure 5As shown, the mounting device for the fan 70 includes a first vibration damping structure 61 located below the fan 70, and a second sealing structure 40 located above the fan 70. The second sealing structure 40 and the first vibration damping structure 61 are configured to mount the fan 70. Both the sealing structure and the vibration damping structure are made of flexible materials. The fan 70 is held in place by the second sealing structure 40 and the first vibration damping structure 61, reducing the vibration transmitted from the fan 70 to the mounting device. The bottom structure 10, the middle structure 30, and the top structure 50 are less affected by the vibration of the fan 70.
[0074] like Figure 5 As shown, the bottom structure 10 includes a bottom shell 11, and a first sealing structure 20 is located on top of the bottom shell 11. An air inlet channel 12 is formed within the bottom shell 11, and the air inlet channel 12 has a second channel inlet 121 and a second channel outlet 122 (see...). Figure 8 The underlying structure 10 includes a second noise reduction component 13, which is located within the air intake channel 12 and reduces noise in the air within the air intake channel 12. A third connecting pipe is provided at the second channel inlet 121, which connects to the ventilator's casing (see...). Figure 2 The middle structure 30 includes a first ventilation duct 34, which connects the bottom structure 10 and the top structure 50. The second channel outlet 122 is connected to the second ventilation duct 35 (see...). Figure 8 ).
[0075] like Figure 6 As shown, the mounting device for the fan 70 includes a second vibration damping structure 62, which is located between the inner wall of the top structure and the top of the fan 70. The first vibration damping structure 61 includes a support ring 611 that supports the bottom of the fan 70; the first vibration damping structure 61 also includes a support column 612 connected to the side of the support ring 611 (see [reference]). Figure 13The middle layer structure 30 includes a middle shell 31, which is located above the bottom shell 11. The middle layer structure 30 includes a third noise reduction component 36, which is located at the bottom of the middle shell 31 and at the corresponding position of the annular hole, such that both ends of the annular hole face the air inlet 72 and the third noise reduction component 36, respectively. The third noise reduction component 36 reduces noise from the fan 70. A support column 612 is mounted on the third noise reduction component 36, which supports the support ring 611 and the fan 70. The middle layer structure 30 includes a second ventilation duct 35, which connects the top layer structure 50 and the middle layer structure 30. The third noise reduction component 36 includes an upper noise reduction structure and a lower noise reduction structure, with the upper noise reduction structure connected to the middle shell 31 (see [link]). Figure 8 The lower noise reduction structure is connected to the second noise reduction component 13 (see [link]). Figure 7 The upper noise reduction structure can be made of microporous plates, and the lower noise reduction structure can also be made of microporous plates.
[0076] like Figure 7 As shown, the second sealing structure 40 includes a first connecting pipe 42, which is connected to the air outlet 71 of the fan 70 (see...). Figure 10 The second sealing structure 40 includes a second connecting pipe 43. The second sealing structure 40 includes a second sealing frame 41 (see...). Figure 12 The shape of the second sealing frame 41 is consistent with the shape of the middle shell 31.
[0077] like Figure 8 As shown, the air intake channel 12 is U-shaped and is isolated from the upper noise reduction structure.
[0078] like Figure 9 and Figure 10 As shown, an air outlet channel 32 is formed within the middle shell 31. The air outlet channel 32 has a first channel inlet 321 and a first channel outlet 322. A first connecting pipe 42 connects the air outlet 71 and the first channel inlet 321, and a second connecting pipe 43 is disposed at the first channel outlet 322 and connects to other components of the ventilator. The middle structure 30 includes a first noise reduction component 33, which is located within the air outlet channel 32. The first noise reduction component 33 can be a microporous plate or a grid. The second sealing structure 40 includes a sealing layer 44, which is located within and connected to the second sealing frame 41. A first through hole 441 is formed on the sealing layer 44, through which the top of the fan 70 passes (see...). Figure 6 A second through-hole 442 is formed on the sealing layer 44, through which the first ventilation duct 34 passes (see...). Figure 5A third through-hole 443 is formed on the sealing layer 44 (see...). Figure 12 The third through-hole 443 allows the second ventilation pipe 35 to pass through (see...). Figure 6 ).
[0079] like Figure 11 As shown, the first sealing structure 20 includes a first sealing frame 21, which is rectangular and specifically matches the shape of the bottom shell 11 (see Figure 1). Figure 7 The first sealing structure 20 includes a first ring portion 22, which is disposed on the outside of the first sealing frame 21 to facilitate the passage of the locking accessory to connect the bottom shell 11 and the middle shell 31. The number of first ring portions 22 can be configured as needed.
[0080] like Figure 12 As shown, the second sealing frame 41 and the sealing layer 44 form an integral structure. The second sealing structure 40 further includes at least one second ring portion disposed on the outside of the second sealing frame 41, through which a locking accessory passes to achieve the connection between the top layer structure 50 and the middle shell 31 (see...). Figure 7 ).
[0081] like Figure 13 As shown, the support ring 611 is bowl-shaped with an annular hole at the bottom. There can be multiple support columns 612, for example, three support columns 612 can be used.
