At this time, the left and right circular sheets of the holding member 20 are held. In addition = paper member or activated carbon sheet: more used in film and so on. For example, the material of the electrolyte which is vaporized by crepe paper (synthesis ancient eight J cloth: f 4, or other; absorbable, etc. T electrolyte absorbent G is == the liquid gelatin cyclodextrin, also It is called 瑷 宣 μ μ ^ and 衣 衣 糊 。 It is called "α-becoming a tuber called "γ^晨dextrin". It is a dip-dextrin", a ring-shaped structure of cyclodextrin combined with 8 glucoses; or a hole of a degree of internal molecules. Within the hole ^ ar ^ f he is relatively small cyclodextrin 0.6-0.8mn, γ_cyclodextrin 〇 8 is called dextrin 〇 _45-〇. 6nm, β_ pores are lipophilic, externally hydrophilic Born. 11111 or so. In addition, 'cyclodextrin's empty space makes this cyclodextrin act as electric 觫 w ° • liquid absorbent 22, considering that the vaporized 201205617 electrolyte component is included in the hole of cyclodextrin. The cyclodextrin is most preferably a cyclodextrin. If cyclodextrin is used as the electrolyte absorber 22, even if it touches a small amount, the effect of the electrolyte can be used as a good defense. Smoke countermeasures. b is also transmitted as: the best electric miscellaneous (four) 22 _ Kezhen, but the size of the eight-r/r hole of the traitor has an impact. That is, our inference should be: The wave size = ^5, although the size of the holes is different, but the p body is the size of the inclusion steam H = the size of the good hole. Also think about it; α-cyclodextrin and γ-cyclodextrin are water ', six' , ρ-, dextrin is a property of poor water solubility. Capacitor element or electrolyte ^, water in the case of this - when the open pressure release mechanism, the water is also made #2 to Ρ • cyclodextrin In order to achieve poor water solubility, it is difficult to produce a function that is discharged by the water-based gas and discharged to the electrolytic solution. | n Recording absorption of the capacitor (4), the rise in the outer casing 12 In the case, the vaporized electrolyte passes through the safety valve 14 between the bottom surface of the member 2 2 and the crocodile portion 12a to hold the member 20 ===, the electrolyte. Further, the holding member 20 is When it is raised and raised, the safety valve 14a provided in the holding member 20 is opened. At this time, since the electrolytic solution is sucked by the electrolyte absorbent 22, hydrogen gas is used. The electrolyte is discharged to the outside, but the electrolyte solution of n/ί匕 is sucked by the electrolyte absorbent 22 and is not discharged to the outside, and the holding member 20 is made of a metal such as a vapor, so that even if the vaporization b is strongly Except for the discharge, the member 2G is still not (4) < = retained in the holding member 20. The electrolyte of the mvi匕, in addition, the outer casing 12' is connected to the crotch portion 2a from the bottom surface of the crocodile The portion is inclined, so that the strength of the wire of the outer casing 12 and the crocodile portion is increased. j, the opening of the safety valve 12a is facilitated, and the electrophoresis of the vaporization is strongly discharged between the g-piece 20 and the bottom surface of the outer casing 12 without gaps. It can prevent electrolysis 201205617 full valve 14 from being discharged. _ U describes the function of the thin plate 25 of the attachment member 24, and the vaporized electrolyte 'distributed by the thin plate 25 is diffused around it, and is divided into four. Since the outer casing 12 is normally opened when the safety room 14 is opened, the electrolyte of the second emulsion and the vaporization is strongly discharged from the safety valve 14. Unset part 23' 24 Condition 'The gas and vaporized electrolyte are easily discharged straight out of the filter structure 22 to the outside. In this state, the remote sputum absorbing solution absorbent 22 may not be able to exert the full valve μ of the electrolyte that absorbs vaporization, so that the self-safety bell 14 discharges the electric ^3 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容 容吏 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = The electrolyte is absorbed. When the effect of the liquid absorption of the electrolyte is changed, the amount of the electrolyte which is inhaled and vaporized becomes small, and 匕 = the open pressure release mechanism can visually recognize the degree of smoke. New York liquid flows out to the outside to form a weight ratio of 'powered: two t two with 4 denier solution weight? The situation forms a smoke-like outflow to the electrolytic capacitor crying. 3 or more, so as to prevent the weight of the collector 22 from being loaded with 〇.3;; the second is about ^^^ ^ for the electrolyte suction = the final period, in general Availability ® 2 〇 All sides show the diagram of the fixing mechanism (a) f ” Figure 3 is a self-safety diagram (8). In addition, the components 1 to 201205617 which are the same as the side of the direction of the actual observation arrow are given the same reference numerals, and the overlapping description will be omitted. First, in Embodiment 2, without using the holding member 2, a stack of the electrolyte absorbent 22 sandwiched by the filter members 23, 24 as shown in FIG. 2 is placed together with the sheet 25 and placed in the housing 12 space. Thereafter, the fixing solution absorbent 22 shown in Figs. 3 (8) and (b) is inserted into the storage space and pressed against the thin plate 25 to cause mosquitoes. Thereby, the electrolyte absorbent is pushed to increase the density of the absorbent, and the suction can be further improved (4). Push the suction _ 22 to reduce the part of the change. Therefore, the release mechanism of the aerial mosquitoes, the pro-existing Wei Xian m collectors absorb the ground th to the outside. 1] ” Here, the fixing structure 26 will be described.
