New description: [New technology field] This creation department is about the field of optical lens technology. [Prior Art] A conventional optical lens unit is one to several lenses in a lens barrel for use in a camera or other various optical devices, wherein the lens is firmly fixed in the lens barrel, and A glue is applied between the lens barrels to glue the lens to the lens barrel. β However, the problem of poor focusing in such an optical lens is more specific. Therefore, there are many separate gaps between the lens and the lens or between the lens and the optical device or the lens holder. Filled with air, when the external environment temperature rises or scales down, the light towel is lighter than the temperature and expands or shrinks, which in turn causes the air to squeeze each lens or optical device, and the focal length between the lenses is changed. Hybrid neon change, the accuracy of the navigation distance is reduced, and the image quality obtained by the IX preparation is also reduced. In order to overcome the above problems, the industry is more than the side of the lens barrel drilling and exhausting, and then filling it after exhausting. The technical problem arising from this method is complicated. As for the lens, 'and the %& in process' The problem of rising causes the residual gas of the mirror to expand, so that the assembled lens has a high defect rate technical problem. In addition, as far as I know it, there is also an industry that additionally processes a gas vent in the inner wall of the lens barrel to discharge it into the lens. The technical problem of this method is that the original lens barrel needs extra sharp air venting groove, the processing procedure becomes complicated and the cost increases. In addition, the single M404388 industry-exhaust flow channel will affect the flow direction and speed of the gas. The design of the gas inside the lens is unreasonable. 5 [new content] ...

Therefore, the lens exhaust structure provided by the present invention (1) allows the air to enter the lens barrel accommodating space through the venting area reserved by the sealant layer when the ambient temperature changes, and then the escape air passage of the accommodating space Discharge to the outside to prevent the residual air in the lens barrel from pushing the lens group due to thermal expansion, so that the lens in the lens barrel is maintained at the preset position 4 to ensure the optimal imaging focal length and quality effect of the optical lens. [Embodiment] The following is only a description of the possible real-life examples of the creation, but it is not intended to limit the age of the gambling gambling. % Refer to Figs. 1 to 3' This invention provides a lens exhaust structure (-) including a lens barrel 1, a lens group, and a sealant layer 4. The lens barrel 1 has an inner surface 丨1 and an outer surface 12, and the inner surface 11 has a valley chamber, wherein the two ends of the lens barrel 2 in the axial direction respectively have an opening D 13 and a The second opening 14 is respectively connected to the accommodating space for allowing light to enter from the first opening 13 and to be ejected from the second opening. Preferably, the outer surface 12 is provided with a thread. More specifically, the lens barrel 1 has a bottom plate 15 and a fiber 16, and the bottom plate 15 is formed with the first opening 13'. The side plate 16 has the inner surface u and the outer surface 12, and is surrounded by the side plate j. The accommodating space is defined by the side opening 16 and the bottom plate 15 between the first opening 13 and the second opening 14 . The lens set includes one or more lenses U, which may include a mirror and a lens. Each lens 2, in particular, an optical lens may have two optical surfaces, and a fixed portion 212. The lens group further includes a clip. There is an annular visor 22, a cymbal 23 and a fixed ring % between the respective lenses. If the lens barrel with a frog mirror is shown in FIG. W, it further includes one or more of the mirrors 25 disposed outside the fixing ring 24. (or flat glass). The lens 21 is received in the accommodating space. Each of the lenses 21 has a peripheral edge 213, and the inner surface 11 of the M404388 of each of the peripheral edges 213 has the same cross-sectional profile. The peripheral edge 213 is abutted against the inner surface lb. Specifically, each of the lenses 21 can be formed with a cut-out 214, and the inner surface u can form a cross-sectional profile corresponding to the cut-off 214, so that the lens 21 can be relatively firmly fixed to the lens barrel 1 and, in addition, each lens An escape air passage A is defined between the peripheral edge 213 and the wall surface of the inner surface u of the lens barrel. The escape air passage A has a first end and a second end, and the first end thereof communicates with the first opening 13 of the lens barrel. Further, the fixing portion 212 of each of the lenses 21 can form a fine circular arc angle 215 by forming a rough surface, or (and) the peripheral edge 213 of each lens, so that the gas passes through the rough surface or (and) the rounded corner 215. And connected to the escape air passage a, and finally discharged from the first opening row. <Refer to referring to Figures 2, 2-1 and 3, the sealant layer 4 is annularly slanted at the junction of the lens group and the lens barrel near the second opening, more clearly, if 2 Figure 2 In the implementation of the mirror of the mirror, the sealant layer* is placed at the joint between the outer surface of the fixing ring 24 and the lens barrel at the most sin of the lens group. If it is the mirror tube of the 遽 mirror The sampler is disposed at the junction of the outer surface of the filter or the flat glass closest to the second opening and the lens barrel, thereby sealing the gap between the two members: at the same time, the lens group is fixed to the lens barrel. Space purpose. The above f is set in the mirror 版 mirror plate to join the red (four) ride 4, the touch-gas permeable zone X venting zone 连通 is connected with the second end of the escape airflow path A, and the embodiment of the venting zone can be sealed as shown in FIG. A gap is formed in the preset layer of the glue layer, so that the eve layer C1 can also be spaced apart on the surface of the annular sealant layer as shown in FIG. 3-1, or two notches can be opened at 180 degrees, so that the sealant layer forms two semicircles. 6 M4U4388 Shape ο 糟 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Use for imaging.

挽封膠層之透氣區41流輕鏡筒之容置空間，該容置空間内之 空氣則透過鏡片間之祕表面或圓弧導角而導人逃氣流道 A，最后經逃氣流道連通至第-開口排出域，以利後續鏡 筒、鏡座絲料輕備酿，縱使㈣^騎朗氣體， 亦會循上述路徑自動排氣，進而達到防止組裝環境溫度上升 時’造成容室喊留氣體膨脹，導致鏡片組或鏡座精，而改 變最佳光軸聚焦距離產生優勢。The venting area 41 of the sealing layer flows through the accommodating space of the light barrel, and the air in the accommodating space passes through the secret surface or the arc-shaped corner between the lenses to guide the escape air passage A, and finally communicates through the escape air passage. To the first-opening discharge field, in order to facilitate the subsequent barrel and mirror wire material to be lightly prepared, even if (4) ^ riding the gas, it will automatically exhaust according to the above path, so as to prevent the temperature of the assembly environment from rising. The gas is inflated, resulting in a fine lens set or mirror mount, and the advantage of changing the optimal optical axis focus distance is advantageous.

The arc guide angle, etc., so that the opening position of the venting zone is not directly connected with the Wei flow path of the lens and the accommodating space, and the residual gas inside the lens barrel can be smoothly discharged. Furthermore, 'the above-mentioned creation provides the gas that enters the space of the lens barrel from the direction of the ventilated area', and can flow through the escape air passage. The entire exhaust structure design does not need to change the lens barrel itself (such as the inner wall surface The groove ventilation structure can be based on the effect of not increasing the lens barrel plus the J1 program and the cost of the lens (4) gas discharge 7 M404388, which is a proof of progress.
