體13。在此，第1圖係壓力檢測器1〇之概略截面圖。 殼體11具有凹部12，以樹脂成形構成。凹部12可以預 8 先設置對應射出成型用模具之形狀，簡單地形成。惟，本 發月未限疋殼體11之讨質。殼體11亦可為搭載壓力檢測器 10之資成機器之殼體一部份。设體11在特定之水壓下不變 升/且具有將板體13支撲成可變形之支撐部iia。支樓部lla 在開口部12a周圍之一定範圍。 凹。卩12具有位於第1圖上端部之圓形開口部i2a，且具 有圓形底面l2b。結果，凹部12呈圓柱形。惟，本發明未將 凹。卩12之形狀限定在圓柱形。舉例言之，凹部12為具預定 長又之溝板體13亦可具有覆蓋其之條狀。在本實施例中， 右無板體13，凹部12便露出至外部。然而，當將壓力檢測 益10搭載於資訊機器時’由於多為搭載於無法從外部觀看 之部位’故當無板體13時，可選擇凹部12是否露出至外部。 凹部12只要為容許足以使板體π破損之程度之變形即 可。舉例言之，沿第1圖之C方向之凹部12之深度設定成凹 部丨2之底面i2b在板體13之彈性變形範圍不與板體13接 觸。這是由於在板體13彈性變形成之範圍，板體13與底面 l2b接觸時’板體13無法再進一步變形而損壞之故。 板體13覆蓋凹部12之開口部12a，藉由圖中未示之接著 劑接著於支撐部11a。板體13固定於支撐部Ua，且可在置 於特定水壓之環境時便破損。板體13呈圓板形’板體13之 圓板中心與凹部12之底面12b之中心配置於同一直線C上。 惟，板體13不需完全覆蓋開口部12a。 在本實施例中板體丨3破損，而在本發明中’只要在特 疋壓力塑性變形即可。這是由於可以塑性變形之有無，檢 1336775 測特定壓力之故。本發明並未限定板體13之形狀、材質、 厚度。舉例言之，板體13可棟用不透水之紙、尼龍/PET等 樹脂板、彈性體等。 藉調節凹部12之尺寸與板體13之尺寸（厚度或直徑），或 5變更板體13之材質，可調節板體13之破損強度。舉例言之， 若增厚板體13或縮小板體13之直徑’板體丨3不易破損，若 使板體13變薄或增大板體13之直徑，板體13則易破損。 第1圖顯示在常壓下之壓力檢測器丨〇。第2(a)圖顯示施 加未達特定水壓之壓力之壓力檢測器10。第2(b)圖顯示施加 10 特定水壓以上之壓力之壓力檢測器10。 壓力檢測器10置換成如第3 (a)圖及第3 (b)圖所示之壓 力檢測器l〇A亦可。壓力檢測器10A與壓力檢測器1〇之不同 點為除了具有上述殼體Π及板體13外，更具有突起14，在 此’第3(a)圖及第3(b)圖係用以說明壓力檢測器10A之動作 15 之概略截面圖。 突起14於凹部12之底面12b上與板體13相對設置。如第 3(a)圖所示，突起14在頂點14a與彎曲至凹部12内之板體^ 接觸’如第3(b)圖所示，板體13易破損。在本實施例中，突 起丨4呈圓錐形。連結圓錐底面中心與頂點14a之直線與上述 2〇直線C—致。此外’突起14只要為在前端得以施加高壓力 者’為針狀或角錐等其他形狀亦可。 藉變更突起14之高度’可調節板體丨3之破損強度。在 本實施例中，突起14配置於凹部12之底面12B之中央，本發 明並未限定突起14之位置。突起14可為殼體11之一部份， 10 亦可為其他構件。若為殼體11之一部份時，可以射出成形， 形成一體。若與殼體Π為不同構件時，可以壓入等，安穿 於殼體η。未限定突起之材質14，由於需為與板體13接觸 而使之破損之程度的強度，故以樹脂、金屬等硬材料為佳。 壓力檢測器1 〇亦可置換成第4圖所示之壓力檢測器 10Β。在此，第4圖係壓力檢測器10Β之概略截面圊。如第 2(a)圖及第2(b)圖所示，殼體11之支撐部Ua之凹部與角部 iib截面呈角形。因此，如第2(b)圖所示，於板體13破損前， 在第2(a)圖之狀態，板體13與角部Ub接觸，因角部Ub施加 之壓力，板體13有破損之虞。 壓力檢測器10B置換成將角部11 b形成倒角或呈r形狀 (以下僅稱為「形成倒角」）之角部llc。在此，第4圖係壓力 檢測器10B之概略截面圖。在角部丨卜中，殼體11與板體13

1336775 在壓力檢測器10A至10D中，為可以目視明確判斷板體 13是否破損’亦可使凹部12之内面、例如底面ub與板體13 之顏色不同。為使不同之顏色顯眼，亦可設定成補色關係。 壓力檢測器1 〇置換成第7圖所示之壓力檢測器1 亦 5可。在此，第7圖係壓力檢測器10E之概略截面圖。壓力檢 測器10E與壓力檢測器10不同點在使用板體13A取代板體 13。板體13A具有板體13A^13A2在端部13A3貼合之雙重 構造。因而，板體13A之中央部未接著，而可形成空洞13a4。 空洞13A4封入與板體顏色不同之著色材18。著色材18含有 10塗料、墨水、染料之固體及液體等。因夾入著色材18，故 板體13破損時’該等將板體13著色，而提高板體13破損之 目視辨認性。 【第1實施例】BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure detector, and more particularly to a pressure detector for detecting whether or not a pressure above a predetermined pressure is applied. The present invention is applicable to the detection of whether or not a mobile phone is placed at a water depth of more than 2 m. BACKGROUND OF THE INVENTION 10 Due to the popularity of mobile information devices in recent years, the environmental assurance of mobile information devices is important. At this time, it is necessary to simply and inexpensively measure whether the machine is in an environment that is guaranteed. One of the environments that should be guaranteed is pressure. For example, many of the mobile phones are environmentally guaranteed to withstand a predetermined water depth of 2 m. This is for the manufacturer to ensure that even if the mobile phone is inadvertently soaked, the environment will not be damaged as long as it is within the guaranteed range. Therefore, the manufacturer can repair the mobile phone free of charge when the environment within the guaranteed range cannot be withstood. The prior art has patent documents 1 to 3. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2006-177919 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2001-H6637 No. 2 [Patent Document 3] Japanese Patent Publication No. 2002-181228 [Abstract] In the past, when the mobile phone was damaged by water immersion, the manufacturer could not simply judge whether the mobile phone was dropped to a depth exceeding the guaranteed range or the water depth of the mobile phone 5 1336775 could not bear the guarantee. At this time, if the water depth is within the guaranteed range, the water must be allowed to come into contact with the mobile phone. Therefore, it is not enough to carry a medium for chemical detection of water on a mobile phone. Therefore, in the current mobile information machine with waterproof function, there is no small and low-cost water pressure detector. Of course, this problem also occurs in mobile information devices other than mobile phones such as personal digital assistants (PDAs), notebook personal computers (PCs), watches, computers, game consoles, audio machines, and storage devices. Accordingly, the present invention is directed to providing a pressure detector that can easily and inexpensively detect pressure and an information machine having the same. The pressure detector of the present invention is for detecting a predetermined pressure, and includes a casing having a recess; and a plate covering the recess and being rupturable when placed in an environment above the predetermined pressure. The pressure detector can mechanically detect the predetermined pressure by breaking the plate. In another aspect, the pressure detector of the present invention is for detecting a predetermined pressure, and includes a support portion that is not deformed under the predetermined pressure of 15 and is deformably mounted to the support portion, and can be placed in the foregoing When the environment is above a predetermined pressure, a plastically deformed deformation member is produced. The pressure detector mechanically detects a predetermined pressure by deforming the deformation member. The pressure detector may further include a projection which is provided in the concave portion 20 so as to face the plate body, and is in contact with the plate body bent into the concave portion to make the plate body easily damaged. With this protrusion, the pressure control of the plate body breakage can be easily performed. Further, it is preferable that the contour of the recessed portion in contact with the aforementioned plate body and defining the casing forms a chamfer. Thereby, it is possible to prevent the plate body from being damaged by the corner of the casing within the elastic deformation range before reaching the predetermined pressure, and 6 1336775 can improve the pressure detection accuracy. The recessed portion may have a through hole penetrating through the casing, and the pressure detector may have a through-hole that covers the through-hole, and the air may pass through, and the water may not pass through. Therefore, the function of the pressure check and the (four) water pressure detector can prevent the plate body from being damaged by the pressure of the water pressure material. The pressure detector may further include a protective member, and the protective member is disposed opposite to the front material company, and is shaped to protect the front plate from being deformed on the opposite side of the concave portion. And 10 15 broken. This prevents the internal pressure of the concave portion from rising in the atmosphere where the air pressure is low, such as in the aircraft, and the plate body is crushed and broken. The inner surface of the concave portion is different from the color of the plate body. Thereby, the visibility of the board when it is damaged can be provided. Further, it is preferable to further include a member which is disposed in the concave portion 4 and has a physical property change after the reaction with water and maintains its state even after drying. With this member, it is possible to provide damage to the plate body and visual recognition when the inside of the recess is immersed in water. The plate body has a double structure, and the pressure sensor may further include a color material that is sandwiched between the inside of the plate body and has a different color from the plate body. The coloring material contains solids and liquids for paints, inks, dyes. Since the coloring material is sandwiched, when the plate body is broken, the plate body is colored, and the visibility of the plate body damage can be improved. Other objects and features of the present invention will become apparent from the following description of the preferred embodiments.

[Embodiment 3] Best Mode for Carrying Out the Invention Hereinafter, the pressure detector 10 of the present invention will be described with reference to additional drawings. The pressure detector of the present invention is used to detect a predetermined pressure, and in the present embodiment 20, a specific water pressure is detected. The pressure detector 10 can be mounted on an information machine, separate from the information machine, or assembled into an information machine and integrated with the information machine. As shown in Fig. 1, the pressure detector 10 has a casing 丨丨 and a plate body 13. Here, the first drawing is a schematic cross-sectional view of the pressure detector 1A. The casing 11 has a recess 12 and is formed by resin molding. The recessed portion 12 can be formed by simply setting the shape of the corresponding injection molding die. However, this month is not limited to the appeal of the casing 11. The housing 11 can also be part of the housing of the capital machine in which the pressure detector 10 is mounted. The body 11 does not rise under a specific water pressure and has a support portion iia that slaps the plate body 13 into a deformable portion. The branch portion 11a has a certain range around the opening portion 12a. concave. The crucible 12 has a circular opening portion i2a at the upper end portion of Fig. 1 and has a circular bottom surface 12b. As a result, the recess 12 has a cylindrical shape. However, the present invention is not concave. The shape of the crucible 12 is limited to a cylindrical shape. For example, the recessed portion 12 having a predetermined length of the slab body 13 may have a strip shape covering it. In the present embodiment, the right plate body 13 is not present, and the concave portion 12 is exposed to the outside. However, when the pressure detecting benefit 10 is mounted on the information device, it is often mounted on a portion that cannot be viewed from the outside. Therefore, when the plate body 13 is not provided, whether or not the concave portion 12 is exposed to the outside can be selected. The concave portion 12 may be deformed to a degree sufficient to allow the plate body π to be broken. For example, the depth of the concave portion 12 in the C direction of Fig. 1 is set such that the bottom surface i2b of the concave portion 不2 does not contact the plate body 13 in the elastic deformation range of the plate body 13. This is because the plate body 13 cannot be further deformed and damaged when the plate body 13 is in contact with the bottom surface l2b in the range in which the plate body 13 is elastically deformed. The plate body 13 covers the opening portion 12a of the recessed portion 12, and is adhered to the support portion 11a by an adhesive (not shown). The plate body 13 is fixed to the support portion Ua and can be broken when placed in a specific water pressure environment. The plate body 13 has a disk shape. The center of the disk plate of the plate body 13 and the center of the bottom surface 12b of the recess portion 12 are disposed on the same straight line C. However, the plate body 13 does not need to completely cover the opening portion 12a. In the present embodiment, the plate body 3 is broken, and in the present invention, it is only required to be plastically deformed under special pressure. This is due to the possibility of plastic deformation, check 1336775 to measure the specific pressure. The shape, material, and thickness of the plate body 13 are not limited by the present invention. For example, the plate body 13 may be made of a water-impermeable paper, a resin plate such as nylon/PET, an elastomer or the like. The damage strength of the plate body 13 can be adjusted by adjusting the size of the recess 12 and the size (thickness or diameter) of the plate body 13, or changing the material of the plate body 13. For example, if the plate body 3 of the thickened plate body 13 or the reduced plate body 13 is not easily broken, if the plate body 13 is thinned or the diameter of the plate body 13 is increased, the plate body 13 is easily broken. Figure 1 shows the pressure detector 常 under normal pressure. Figure 2(a) shows a pressure detector 10 that applies a pressure that does not reach a certain water pressure. Figure 2(b) shows a pressure detector 10 that applies a pressure above 10 a specified water pressure. The pressure detector 10 may be replaced by a pressure detector 10A as shown in Figs. 3(a) and 3(b). The pressure detector 10A differs from the pressure detector 1A in that it has a protrusion 14 in addition to the housing case and the plate body 13, and the '3' and 3(b) drawings are used here. A schematic cross-sectional view of the action 15 of the pressure detector 10A will be described. The protrusion 14 is disposed opposite to the plate body 13 on the bottom surface 12b of the recess 12. As shown in Fig. 3(a), the projection 14 is in contact with the plate body 14 bent into the concave portion 12 as shown in Fig. 3(b), and the plate body 13 is easily broken. In the present embodiment, the projection 4 is conical. The line connecting the center of the bottom surface of the cone to the apex 14a is aligned with the above-mentioned 2 〇 line C. Further, the projections 14 may have other shapes such as a needle shape or a pyramid shape as long as a high pressure is applied to the tip end. The breaking strength of the plate body 3 can be adjusted by changing the height of the projections 14. In the present embodiment, the projection 14 is disposed at the center of the bottom surface 12B of the recess 12, and the position of the projection 14 is not limited by the present invention. The projections 14 can be part of the housing 11, and 10 can be other components. If it is part of the casing 11, it can be injection molded and integrated. If it is a different member from the casing, it can be pressed in, etc., and it can be worn through the casing η. The material 14 of the unrestricted protrusion is preferably a hard material such as a resin or a metal because it needs to be in contact with the plate body 13 to be damaged. The pressure detector 1 〇 can also be replaced with the pressure detector 10 所示 shown in Fig. 4. Here, Fig. 4 is a schematic cross-sectional view of the pressure detector 10Β. As shown in Figs. 2(a) and 2(b), the concave portion of the support portion Ua of the casing 11 and the corner portion iib have an angular cross section. Therefore, as shown in Fig. 2(b), before the plate body 13 is broken, in the state of Fig. 2(a), the plate body 13 is in contact with the corner portion Ub, and the plate body 13 has the pressure applied by the corner portion Ub. Damaged. The pressure detector 10B is replaced with a corner portion llc which is chamfered or has an r-shape (hereinafter simply referred to as "chamfering"). Here, Fig. 4 is a schematic cross-sectional view of the pressure detector 10B. In the corner portion, the casing 11 is in contact with the plate body 13 while defining the contour of the recess 12. By forming the corner portion uc into a chamfer, when the plate body 13 is elastically deformed, the plate body 13 is not damaged before a specific pressure. Further, the support portion 11a is also changed to the support portion 11d, and the plate body 13 is slightly enlarged to ensure the same area as the support portion 11a. Of course, the configuration shown in Fig. 4 can also be combined with the pressure detector 10. The pressure detector 10 can also be replaced with the pressure detector 1 〇 C ° shown in Fig. 5, and Fig. 5 is a schematic cross-sectional view of the pressure detector i 〇 c. The pressure detector 10C differs from the pressure detector 1C in that the casing n has a through hole 1 2A 'the semi-transmissive film 15 covers the lower opening portion 12c of the through hole 12A. The fifth through hole 12A has an upper opening portion i2a and a lower opening portion 12c. The through hole 12A has a shape in which two cylinders of different diameters are overlapped, and penetrates the casing 1336775 around the opening portion 12c, and the casing n has a support portion ue on the bottom surface. The semi-permeable membrane 15 is then attached to the support portion ne by an adhesive not shown. The semi-permeable membrane 15 covers one end of the through hole 12A, that is, the opening portion 12c, which is a film through which air can pass and water cannot pass. When the plate body 13 is deformed by an external force, the air inside the through hole 12A is discharged to the outside through the opening portion 12c and the semi-permeable film 15. As a result, the internal pressure rise due to the internal volume compression of the through hole 12A can be prevented, and the plate body 13 can be deformed by the desired water pressure. Of course, the configuration shown in Fig. 5 can also be combined with the pressure detectors 1A and 1B. The pressure detector 10 is replaced with the pressure detector 10D shown in Fig. 6. The pressure detector 10D differs from the pressure detector 1B in that it has a protective member 16 and has an emphasis member 17. Here, Fig. 6 is a schematic cross-sectional view of the pressure detector 1A. The protective member 16 is disposed on the opposite side of the plate body 13 from the recessed portion 12, and has a larger area than the plate body 13 to cover the plate body 13. The casing has a support portion 11f on the outer side 15 of the support portion Ua. The protective member 16 is followed by the support portion Ilf by an adhesive not shown. The protective member 16 prevents the plate body 13 from being deformed on the upper side of Fig. 6. As a result, the protective member 16 protects the plate body 13 from being deformed by being deformed on the side opposite to the concave portion 12. For example, the protective member 16 can prevent the plate body 13 from being broken under a reduced pressure environment such as an aircraft. 20 It is emphasized that the member Π is disposed inside the concave portion 12, and after the reaction with water, the physical properties (color, shape 'volume, etc.) are changed, and the member of the bear is maintained even after drying. By this, it is possible to visually determine whether or not the plate body 13 is broken. Of course, the protective member 16 and/or the accent member 17 shown in Fig. 6 can also be combined with the pressure detecting 10A to 10C. 12 1336775 In the pressure detectors 10A to 10D, it is also possible to visually determine whether or not the plate body 13 is broken. The inner surface of the concave portion 12, for example, the bottom surface ub and the plate body 13 may be different in color. In order to make different colors conspicuous, it can also be set to a complementary color relationship. The pressure detector 1 is replaced by the pressure detector 1 shown in Fig. 7. Here, Fig. 7 is a schematic cross-sectional view of the pressure detector 10E. The pressure detector 10E differs from the pressure detector 10 in that the plate body 13 is replaced with the plate body 13A. The plate body 13A has a double structure in which the plate body 13A^13A2 is fitted at the end portion 13A3. Therefore, the central portion of the plate body 13A is not followed, and the cavity 13a4 can be formed. The cavity 13A4 encloses a color material 18 different from the color of the board. The coloring material 18 contains 10 coatings, inks, solids of dyes, liquids, and the like. When the plate member 13 is broken by the coloring material 18, the plate body 13 is colored, and the visibility of the plate body 13 is improved. [First Embodiment]

In the 15 test, as shown in Figs. 8(a) to 8(c), the following procedure was tested, that is, the plate 13 and the needle 14A were mounted on the mold 1 ία. By the water pressure, the plate body 13 is bent, and the needle 14A provided in the mold 11A is punctured, and the plate body 13 is opened to allow the liquid to leak. Here, Fig. 8(a) is a top view of the mold 11A. Figure 8(b) is a cross-sectional view taken along line A-A' of Figure 8(a). Fig. 8(c) is a cross-sectional view of the mold 11A on which the plate body 13 and the needle 14A 20 are mounted. Tap water and red food coloring are used in the immersion liquid. Red food coloring is used for easy visual liquid leakage. The pressing force is 〇 to 〇. 〇 4MPa, 0.005MPa pitch. The liquid leaked out and was visually confirmed. The plate body 13 is a Gore-Tex plate having a thickness of 〇.〇2 mm and a diameter of 18 mm, and an aluminum (Ai) case 2 13 1336775 having a thickness of 0.012 mm and a diameter of 18 〇1〇1. After the plate body 13 and the needle 14A are placed in the mold 11A, water is immersed. After the sample was pressurized in water for 30 seconds, it was taken out to the atmosphere to confirm the state of the Gore-Tex plate and the A1 foil and the presence or absence of liquid leakage.
