[0031] 有关本发明的前述及其他技术内容、特点与功效,在以下配合参考附图的二个较佳实施例的详细说明中,将可清楚地呈现。 [0031] For the aforementioned and other technical contents, features and effects of the present invention, described in detail in the following embodiments with reference to the drawings of two preferred, will appear clearly.

[0032] 在本发明被详细描述之前,要注意的是,在以下的说明内容中,类似的组件是以相同的编号来表示。 [0032] Before the present invention is described in detail, it should be noted that, in the following description of contents, like elements are represented by the same reference numerals.

[0033] 参阅图2与图4,本发明的具有除尘装置的机壳装置2的第一较佳实施例包含一机壳3、一风扇4以及一除尘装置5。 [0033] Referring to FIG. 2 and FIG. 4, the housing means having a dust removing device according to a first preferred embodiment of the invention comprises a housing 2 of 3, a fan 4 and a dust removal device 5.

[0034] 机壳3界定出一气体通道31。 [0034] The housing 3 defines a gas passage 31. 风扇4设置于机壳3内并且位于气体通道31的末端,用以将机壳3内的气体抽出机壳3。 The fan 4 disposed in the inner casing 3 and located at the end of the gas passage 31 for gas extraction in the casing 3 housing 3. 在本实施例中,风扇4设置于机壳3的顶壁,但是风扇4亦可设置于其他位置,不以公开的为限,只要风扇4位于气体通道31的末端且能造成气体在气体通道31内流动即可。 In the present embodiment, the fan 4 disposed on the top wall of the housing 3, but also the fan 4 disposed in other positions, not limited to the disclosure, as long as the fan 4 located at the end of the gas passage 31 in the gas passage and can cause a gas 31 can flow.

[0035] 除尘装置5包括一气流干扰组件52及一黏附组件51,气流干扰组件52具有一倾斜面521。 [0035] The dust removing device 5 comprises a gas flow assembly 52 and interfering adhesion of a component 51, the air flow disturbance assembly 52 has an inclined surface 521. [0036] 本发明的降低机壳风扇吸附灰尘的方法包含以下步骤: [0036] The fan casing of the present invention to reduce dust absorption method comprising the steps of:

[0037] 步骤61 :将气流干扰组件52设置于机壳3内壁面并且位于风扇4的上游处,用以干扰流向风扇4的气流。 [0037] Step 61: The flow disturbances assembly 52 disposed on the inner wall surface of the casing 3 and located upstream of the fan 4, the air flow to the fan 4 flows interference. 在本实施例中,是使用一片体作为气流干扰组件52,该片体是成倾斜设置,上述的倾斜面521即为片体的一侧表面。 In the present embodiment, the body is used as a flow disturbances assembly 52, the sheet member is disposed to be inclined, the surface 521 is the side of the inclined surface of the sheet.

[0038] 步骤62 :将黏附组件51设置于机壳3内壁面而位于气体通道31,并且位于气流干扰组件52的下游处,该黏附组件51用以黏附灰尘。 [0038] Step 62: The adhesion assembly 51 disposed on the inner wall surface of the casing 3 and the gas passage 31 is located, and located downstream of the flow disturbances assembly 52, the assembly 51 for adhesion of dust adhesion. 黏附组件51朝向气体通道31的一侧面511具有黏性而用以黏附灰尘。 A side surface adhesion assembly 51 toward the gas passage 31 having a viscosity of 511 to the adhesion of dust. 而在本实施例中,黏附组件51为一黏贴于机壳3内壁面的双面胶带,但不以此为限。 In the present embodiment, the adhesive assembly 51 is a double-sided tape affixed to the inner wall surface of the housing 3, but is not limited thereto.

[0039] 当风扇4运转时,气体通道31内会由于风扇4抽吸的作用而形成往风扇4流动的气流,而当气流气体通过气流干扰组件52时,气流干扰组件52的倾斜面521的设计会对通过的气流形成干扰,使气流在气流干扰组件52顶端处形成紊流,由于此紊流会减缓气流往风扇4流动的速度,因此,便可让受气流夹带的灰尘在此时有机会因自身重力而落下,并且受黏附于黏附组件51的侧面511上。 [0039] When the operation of the fan 4, the gas passage 31 due to the suction action of the fan 4 to form a gas stream flowing toward the fan 4, and when the gas stream through the flow disturbances assembly 52, the inclined surface 52 of air flow disturbance assembly 521 design would interfere with the air flow through the air flow turbulence in the flow disturbances at the tip assembly 52, since this will slow down the air flow turbulence to the flow rate of the fan 4, and therefore, can allow dirt entrained by the air flows at this time there opportunity to fall due to their own gravity, and adhered to by the adhesive sides of the assembly of 51,151. 如此,便可降低气流夹带的灰尘随着气流流往风扇4 而附着于风扇4上,进而避免风扇4因过多的灰尘附着而影响其抽风效能。 Thus, the dust can be entrained with the gas stream to reduce the airflow to the fan 4 and 4 attached to the fan, the fan 4 further avoid the adhesion of dust due to excessive ventilation affect their performance.

[0040] 补充说明的是,由于考虑到黏附组件51在使用一段时间后会黏附很多灰尘而需要更换,在本实施例中,机壳3包括一壳体32及一活动片33,壳体32具有一开口321,活动片33可分离地结合于壳体32并遮蔽开口321。 [0040] It is added that, taking into consideration the adhesion assembly 51 after a period of time and a lot of dust adhesion will need to be replaced, in the present embodiment, the housing 3 includes a housing 32 and a movable piece 33, housing 32 has an opening 321, the movable blade 33 is detachably coupled to the housing 32 and covers the opening 321. 气流干扰组件52与黏附组件51皆连接于活动片33的内壁面,所以在使用一段时间后,可将活动片33由壳体32取下以将黏附组件51更换,而气流干扰组件52更可以设计成与活动片33 —体成型。 Adhesion assembly 52 and flow disturbances assembly 51 are connected to the inner wall surface 33 of the movable blade, so after a period of use, the movable blade 33 may be removed from the housing assembly 32 to replace the adhesive 51, the assembly 52 can also disturb the air flow activities designed to sheet 33 - shaping.

[0041] 参阅图3,为本发明的具有除尘装置的机壳装置2的第二较佳实施例,其与第一较佳实施例的差异在于气流干扰组件52的设置位置。 [0041] The dust removing device having a housing means refer to FIG. 3, a second preferred embodiment of the present invention of Example 2, the difference from the first preferred embodiment in that the installation position of the air flow disturbance assembly 52.

[0042] 在本实施例中,气流干扰组件52连接于壳体32内壁面且只有黏附组件51设置于活动片33内壁面。 [0042] In the present embodiment, the air flow disturbance assembly 52 is connected to the inner wall surface of the housing 32 and only the assembly 51 disposed on the adhesion of the inner wall surface 33 movable sheet. 由于第二较佳实施例的工作原理与第一较佳实施例的工作原理相同,在此不再重复说明。 Since the working principle of the same working principle of the second preferred embodiment of the first preferred embodiment, description will not be repeated.

[0043] 综上所述,本发明藉由气流干扰组件52的设置,藉此干扰流向风扇4的气流,进而使受气流夹带的灰尘落于黏附组件51而受黏附于黏附组件51,降低气流夹带的灰尘被送往风扇4并且附着于风扇4,确实可有效达到降低风扇4的灰尘吸附,所以确实能达到本发明的目的。 [0043] In summary, the present invention is provided by air flow disturbance assembly 52, whereby the gas flow to interfere with the fan 4, thereby enabling the dust entrained by the air stream falls by adhesion assembly 51 is adhered to the adhesion assembly 51, reducing the gas flow entrained dust is sent to the fan 4 and the fan 4 is attached to, indeed effectively to reduce the dust suction fan 4, it can really achieve the object of the present invention.

[0044] 惟以上所述的内容,仅为本发明的较佳实施例而已,应当不能以此限定本发明实施的范围,即凡是根据本发明权利要求书范围及发明说明内容所作的简单的等同变化与修饰,皆仍属本发明专利涵盖的范围内。 [0044] However the content of the above, the present invention is only preferred embodiments, it should not limit the scope of this embodiment of the present invention, i.e., simplicity of explanation, all equivalents made in accordance with the invention and the scope of claims of the invention changes and modifications are still encompassed within the scope of the present invention patent.
