New description: [New technical field] This creation is related to the application field of ventilation sleeves, especially the ventilation sleeve structure. [Prior Art] According to the current structure of the building, it is usually reserved for several air outlets, with the exhaust of two rooms in the house or the use of ventilation pipes; for example, the tuyere of a kitchen range hood, The air outlet of the bathroom, or the tuyere of the ceiling, is used to connect the exhaust pipe or the vent pipe to circulate the air inside and outside the house, and to discharge the gas with poor smell inside the house. However, it is generally increased - to prevent the invasion of foreign objects such as mosquitoes, but 2 can not open and close the air duct; in addition, if the rain is too heavy, the rain is easy to go down to the air duct (4) rainwater flow 5 The condition of the kiss. In view of this, the creator has improved the shortcomings of the prior art. After years of experience in this--#, he created the creation. [New content] Therefore, the purpose of this creation is to solve the above problems and provide a structure that is simple and can prevent mosquitoes and achieve ventilation and ventilation. The present invention aims to provide a ventilation sleeve structure that avoids the inside of rainwater. In order to achieve the above purpose, the present invention provides a ventilation sleeve structure, which comprises a sleeve which is embedded in a building, the sleeve has an outdoor end and an indoor end, and the sleeve has a first a connecting portion and a fixing portion, the first connecting portion is disposed on an inner wall of the sleeve and located between the indoor end and the outdoor end, and the fixing portion is disposed adjacent to the indoor end; a filter mesh is disposed adjacent to The outdoor end of the sleeve; and a rotating window pivotally disposed between the indoor end of the sleeve and the outdoor end. The axial direction of the pre-rotation is related to the axial direction of the sleeve Vertically, the rotating window is disposed adjacent to the (four) end of the side of the side, and a second connecting portion is disposed corresponding to the first connecting portion of the sleeve, and the rotating window is connected with the first connecting portion by the second connecting portion The portion is connected to close the ventilation of the sleeve, and the rotating window is detachably fixed with the fixing portion at its circumference to close the ventilation of the sleeve. Wherein the first connecting portion and the second connecting portion are detachably fixed by a bolt. The first connecting portion and the second connecting portion are each a magnetic element that can be attracted to each other. The ventilating sleeve structure further includes an upper floor slab and a lower slab, the slab being mixed with the outdoor screaming setting, the lower slatting plate being disposed adjacent to the cake end. Wherein, the upper baffle partially overlaps the lower baffle. Wherein the fixing portion is L-shaped and has a cutout at the bent portion for detachably fixing to the periphery of the rotating window. Wherein the sleeve is formed by a front sleeve section and a rear sleeve section. Wherein, the indoor end is convexly provided with an annular portion for flattening the surface of the M443734 building. The above objects and advantages of the present invention are obtained from the detailed description of the following embodiments and the related aspects. Tian Ran, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiment is described in detail in the present specification, and its construction is shown in the drawing. [Embodiment] The technical means by which the author has achieved the above objectives are described in detail below with the following implementation diagrams, which are known and recognized by others. Please refer to FIG. 1 to FIG. 8 ' , wherein FIG. 1 is a perspective view showing the structure of the ventilating sleeve of the present invention. FIG. 2 is a perspective view showing the structure of FIG. 1 embedded in the building, and FIG. 3 is a front view showing the structure of FIG. Figure 4 is a partial cross-sectional view of Figure 2, Figure 5 is a cross-sectional view of Figure 2, Figure 6 is a schematic view of the opening of Figure 2, Figure 7 is a schematic view of the opening of Figure 4, Figure 8 is a schematic representation of Figure 4 Figure 5 is a schematic view of the opening. The venting sleeve structure 1 of the present invention comprises a sleeve 2, a screen 3 and a rotating window 4. The sleeve 2 is embedded in a building 10 and is connected by a front sleeve section 2〇1 and a rear sleeve section 202, but is not limited thereto; and the sleeve 2 has an outdoor end 21 And an indoor end 22, the outdoor end 21 is adjacent to the outdoor, the indoor end 22 is adjacent to the inner side, and the sleeve 2 further has a first connecting portion 23 and a fixing portion 24'. The first connecting portion 23 is disposed on the sleeve. The inner wall of the barrel 2 is positioned between the inner end 5 22 and the outer end 21. The fixing portion 24 is disposed adjacent to the inner end 22. In this case, the fixing portion 24 may be of an L shape, and has a digging portion 241' at its bent portion for detachably fixing to the periphery of the rotating window 4. Further, the inner end 22 is provided with an annular portion 25 which is convexly connected to the surface of the key 10. According to the net 3 system, it is placed adjacent to the outdoor end 2 of the sleeve 2 to prevent foreign matter such as mosquitoes from entering. The rotating window 4 is pivotally arranged between the indoor end 22 of the sleeve 2 and the outdoor end ^ The axial direction of the turning window 4 is perpendicular to the thin direction of the sleeve 2; the walking ® 2 money room (four) 22 - The side edge is provided with a second connecting portion 41' corresponding to the first connecting portion 23 of the sleeve 2; whereby the rotating window 4 is connected to the first connecting portion 23 by the second connecting portion 41 to close The sleeve 2 is ventilated and ventilated, and the rotating window 4 is detachably fixed to the crotch portion 24 by a rim to open the venting of the sleeve 2. Wherein the 'the first connecting portion 23 and the second connecting portion 41 can be screwed together. The detachable mosquito' or the shirt-connecting portion 23 and the second connecting portion are each a mutually attractable (four) magnetic element, by magnetic The suction is so that the two are detachably fixed (as shown in FIGS. 9 and 10), but not limited thereto. Further, please refer to Fig. U, which is a cross-sectional view showing another embodiment of the present ventilating sleeve structure. The structure of the embodiment is the same as the above-mentioned real_structure, and the difference is that the ventilation sleeve structure of the embodiment further includes an upper jaw 5 and a lower baffle 6, and the upper baffle 5 is away from the outdoor end 2 】 Sound % ge τ... . Set at the main d, the lower baffle is set near the outdoor end 21. The 'upper baffle 5 and the lower 6 series may partially overlap, thereby avoiding rain and rain into the sleeve 2 during rainy weather.
