Generation [Prior Art] The current fan is divided into a blast type and a propeller (axial flow) type. The main difference lies in the difference of the fan blades, and in the spiral medicine fan ^ in order to obtain or turn the wind volume and reduce the recording = The film has increased from the early Sanye County, the case is excellent; the cooling fan used has been increased to the current seven-seven, etc., and the large-scale manufacturers in the domestic agricultural, livestock and industrial industries began to produce people. _ product.胄 ' 已 已 发明 发明 发明 ' ' 常见 常见 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺 螺of. (10) The large number of blades or the center of the j-shaped object is a small ring-shaped knot on a circular piece, which is covered with tens or hundreds of additions::: the outer side of the ring is the air inlet, and the wall of the cup is numb The blade is transparent to the bottom of the cup and has a bottom-shaped piece that is transparent like: /, and the piece is closely combined into a body, and the plurality of leaves are arranged in a ring shape in an annular shape, and all the cups are on the crotch. The individual is completely cut with the round piece. 5200813338 It is the mouth, facing the direction of rotation of W, so when this leaf cup blade is equivalent to a propeller fan, it has the effect of blowing and exhausting. τ The invention of Wei is mainly to increase the air volume, so that the number of winds of the original fan is determined by the same motor, number of revolutions and mechanism: 5 The rotation of the propeller and the cross-sectional area and the number of propeller blades If the blade of the above fan is replaced by the blade of the present invention, the fan air volume is determined by:
罩杯狀葉片進風口之截面積與罩杯數量的乘積 *因此根據本發明在較佳的設計下，意即在適當的罩杯 狀葉片之尺寸與數量下，欲增加同一風扇之風量是沒問題 的0 【實施方式】 請參閱第二圖及第三圖，第三圖中3Β為三英叶螺旋槳式 散熱風扇之造型視圖，而將此螺旋槳式散熱風扇之葉片以本發 明之葉片取代後即成了本實施例之風扇，如第三圖中3/所 示0 【圖式簡單說明】 第一圖係本發明之平面三視圖。 第二圖係本發明之立體造型表現圖。 第三圖係實施前(3Β)，與實施後(3Α)之立體造型表現圖。 【主要元件符號說明】 11 軸心環 12 罩杯狀葉片 13 進風口 14 出風口 6The product of the cross-sectional area of the air inlet of the cup-shaped blade and the number of cups * Therefore, according to the preferred design of the present invention, that is, under the size and number of appropriate cup-shaped blades, it is no problem to increase the air volume of the same fan. [Embodiment] Please refer to the second figure and the third figure. In the third figure, 3Β is a modeling view of a three-letter propeller type cooling fan, and the blade of the propeller type cooling fan is replaced by the blade of the present invention. The fan of this embodiment is shown as 3/ in the third figure. [First description of the drawings] The first figure is a plan view of the plane of the present invention.
