Description

Anti-leakage fan equipment and its anti-leakage structure

This creation relates to a kind of fan equipment, in particular to a kind of anti-leakage fan equipment and its anti-leakage structure.

Most of the existing fan equipment is not equipped with an anti-leakage structure, as shown in Figure 1. When such a fan device is used to discharge harmful gas, the harmful gas will be sucked in from one of the input and output ports I/O1 and I/O2 of the fan device, and from one of the input and output ports I/O1 and I/O2 The other discharge. During this draining process, harmful gases are likely to leak into the room from the gap GAP between the fan cover 11 and the rotating shaft 30, thereby causing harm to indoor personnel.

In response to this demand, fan equipment with anti-leakage function is now available on the market. As shown in Figure 2, it mainly fixes the mechanical shaft seal 40 on the fan cover 11 and the rotating shaft 30 to cover the fan cover 11 and the rotating shaft 30. The gap GAP between the rotating shafts 30 prevents harmful gas from leaking from the gap GAP. However, the structure of the mechanical shaft seal 40 is complicated and the cost is relatively expensive.

Therefore, the main purpose of this creation is to provide a leak-proof fan device and its leak-proof structure with a relatively simple structure and a relatively low cost.

The invention provides an anti-leakage fan device according to an embodiment, which includes: a fan device, including a fan cover and a fan shaft, the fan cover exposing the fan shaft; a driving device, including a drive housing; and a rotation Shaft, the opposite ends of which are used to rotate with the fan The shaft is connected with the driving device; and a sealing member in the shape of a sleeve for sheathing the rotating shaft, and two opposite ends of the sealing member are respectively fixed to the fan cover and the driving housing.

According to an embodiment of the present invention, a leak-proof structure for a leak-proof fan device is provided. The leak-proof fan device includes a fan device, a rotating shaft, and a driving device. The fan device includes a fan cover and a fan rotating shaft. The fan cover exposes the fan shaft, the drive device includes a drive housing, two opposite ends of the rotation shaft are respectively connected with the fan shaft and the drive device, the leak-proof structure includes a sealing element, the sealing element is The sleeve shape is used to sleeve the rotating shaft, and the opposite ends of the sealing member are used to be respectively fixed to the fan cover and the drive housing.

In another embodiment, the seal is integrally formed.

In still another embodiment, the sealing element includes a first sealing part, a second sealing part, and a third sealing part, one end of the first sealing part is used to be fixed to the fan cover, and the first sealing part The opposite end of the second sealing part is used to detachably connect one end of the second sealing part, the opposite end of the second sealing part is used to be fixed to the driving housing, and the third sealing part is used to cover the first sealing part. Part and the second sealing part.

In still another embodiment, the sealing member is fixed to the fan cover and the drive housing in a screw lock manner.

As a result, the leakage-proof fan equipment provided by this creation can be achieved by arranging a sealing element (that is, an anti-leakage structure), and the sealing element is sleeved on the rotating shaft between the fan device and the driving device, and the opposite ends of the sealing element They are respectively fixed to the fan device and the driving device, so that the gap between the fan device and the driving device and the rotating shaft between the fan device and the driving device can be completely covered to prevent harmful gas leakage in the fan device.

In the following detailed description, many specific details are explained in order to provide a thorough understanding of this creation. However, those of ordinary skill in the art will understand that the creation can be practiced without these specific details. In other cases, well-known methods, procedures and/or components are not described in detail so as not to make this creation unclear.

Please refer to FIG. 3 and FIG. 4. According to an embodiment of the present invention, an anti-leakage fan device includes a fan device 10, a driving device 20, a rotating shaft 30 and an anti-leakage structure 50. The rotating shaft 30 and the leakage prevention structure 50 are located between the fan device 10 and the driving device 20.

The fan device 10 includes a fan cover 11, a fan shaft 12 and a fan blade assembly 13. The fan blade assembly 13 and at least a part of the fan shaft 12 are arranged in the fan cover 11. The fan cover 11 has an opening 14 on the side facing the driving device 20, and the opening 14 can expose the fan shaft 12.

The driving device 20 includes a driving housing 21 and a driving motor (not shown). The drive motor is arranged in the drive housing 21. The opposite ends of the rotating shaft 30 are used to connect the drive motor and the fan shaft respectively 12. When the driving motor is running, the driving motor will drive the rotating shaft 30 to rotate, and the rotation of the rotating shaft 30 will drive the fan shaft 12 to rotate, causing the fan blade assembly 13 to rotate.

The anti-leakage structure 50 includes a seal 51. The sealing member 51 is in the shape of a sleeve and is used to sleeve the rotating shaft 30. The opposite ends of the sealing member 51 are used for fixing to the fan cover 11 and the driving housing 21 respectively, as shown in FIG. 4. The material of the sealing member 51 may be, for example, an elastic material such as rubber, but the present invention is not limited to this example.

In this embodiment, the anti-leakage structure 50 further includes a plurality of locking members 52. The sealing member 51 is fixed to the fan cover 11 and the drive housing 21 in a screw lock manner through these fasteners 52. However, the present creation is not limited to this example; in other embodiments of the present creation, other existing or known fixing methods can also be used to fix the sealing member 51 to the fan cover 11 and the drive housing 21.

Thereby, the seal 51 can completely cover the gap GAP between the fan cover 11 and the rotating shaft 30 and cover the rotating shaft 30 between the fan device 10 and the driving device 20, so as to prevent harmful effects in the fan device 10. The gas leaks to the space outside the sleeve-shaped seal 51 (that is, the space near the end of the driving device 20).

In the embodiment of FIGS. 3 and 4, the sealing member 51 is integrally formed. However, this creation is not limited to this example. For example, as shown in FIGS. 5 and 6, the sealing element 53 is a combined sealing element, which includes a first sealing part 531, a second sealing part 532 and a third sealing part 533. One end of the first sealing portion 531 is used to be fixed to the fan cover 11, and the opposite end of the first sealing portion 531 is used to detachably connect (for example, but not limited to, the first sealing portion 532 of the second sealing portion 532). end. The opposite end of the second sealing portion 532 is used to be fixed to the driving housing 21. The third sealing portion 533 is used to cover the junction of the first sealing portion 531 and the second sealing portion 532. The structure of the combined seal is easier to disassemble, which is beneficial for future replacement.

Although this creation is disclosed above with the aforementioned embodiments, these embodiments are not intended to limit the creation. Without departing from the spirit and scope of this creation, changes, refinements and implementations The combination of are all within the scope of patent protection of this creation.
