  According to this battery-powered alarm device, since the film-shaped seal that covers the second opening is further provided, the seal is covered with the second opening at the time of shipment or when the alarm is attached to each home. If pasted, the user will not be able to see the opposite end of the protruding portion of the operating member from the second opening. For this reason, it is possible to further prevent the user from turning off the power switch by operating the opposite end of the operation member. Moreover, since this seal can be broken, for example, when an alarm continues to sound due to a malfunction, the user can call the pen tip or the film seal with a telephone instruction from the gas company. It is possible to move the knob to the blocking position simply by breaking it using a needle or the like.

  Further, in the battery type alarm device of the present invention, the operation member has a first corner, and the protruding portion is pushed into the resin case to switch the position of the knob to the supply position. In addition, it is preferable that the first corner is in contact with the resin case.

  According to this battery-type alarm device, when the protruding portion is pushed into the resin case and the knob position is switched to the supply position, the first corner portion abuts on the resin case. It is possible to prevent a situation where the portion is pushed into the resin case and the knob of the power switch is destroyed, for example.

  Further, in the battery-type alarm device of the present invention, the operation member has a second corner portion, and the protruding portion is pushed into the resin case and the position of the knob is set as the supply position. It is preferable that the second corner portion abuts on the resin case when the protruding portion is returned to a state protruding from the resin case and the position of the knob is set to the blocking position.

  According to this battery-type alarm device, when the protruding portion is returned to the state protruding from the resin case and the knob position is set to the blocking position, the second corner is in contact with the resin case. It is possible to prevent a situation in which the protruding portion protrudes from the resin case, for example, the operating portion is detached.

  Such a battery-type gas alarm device 1 has a resin case 10 that covers at least an alarm output function unit (gas sensor, microcomputer, and sound output circuit). The resin case 10 includes a front case 11 and a back case 12. On the front side of the alarm device 1, for example, a notification unit 2 provided with an alarm output speaker and a switch unit 3 for stopping and checking the alarm for a predetermined time are formed.

  FIG. 3 is a transparent rear view of the battery-type gas alarm device 1 shown in FIGS. 1 and 2, wherein (a) shows a first state and (b) shows a second state. As shown in FIGS. 3A and 3B, the battery-type gas alarm device 1 has a wiring board 20 inside a resin case 10. The wiring board 20 is formed with wiring for supplying battery power to each part. Such a wiring board 20 is temporarily fixed by a boss 11a extending from the inner side of the front case 11 toward the rear side.

  Further, the battery-type gas alarm device 1 includes a power switch 30 and a switch lever (operation member) 40. The power switch 30 is mounted on the wiring board 20, and the position of the knob 31 can be switched between a supply position P1 for supplying battery power to the functional unit and a blocking position P2 for cutting off the supply of battery power to the functional unit. Switch. The position of the knob 31 is movable in the lateral direction shown in FIG.

  The switch lever 40 is a member that is inserted into the first opening 10 a provided on the side portion of the resin case 10 (rear case 12) and engages with the knob 31 of the power switch 30. 4A and 4B are enlarged views of the switch lever 40 shown in FIG. 3, wherein FIG. 4A is a plan view and FIG. 4B is a top view.

  As shown in FIGS. 4A and 4B, the switch lever 40 includes an engaging portion 41 and an operating portion (projecting portion) 42. The engaging portion 41 is a plate-like member, and a part of the plate is wound through to form an engaging concave portion 41a and an escape concave portion 41b. The engaging concave portion 41a has a convex shape at the penetrating portion, and the knob 31 of the power switch 30 is fitted into the convex tip portion. The escape recess 41b is a portion where the corners of the plate-like member are pierced into a substantially fan shape.

  Further, the plate-like engaging portion 41 is formed with a thin plate portion 41c whose thickness is thinner than other portions in part, and a boundary portion between the thin plate portion 41c and the other portion is a hook portion (second portion). Corner part) 41d.

  The operation part 42 is a trapezoidal member provided at one end of the plate-like engagement part 41. As will be described later, the operation portion 42 has a shape that is flush with the resin case 10 when the knob 31 is at the supply position P1. Further, the operating portion 42 has a shape protruding in the normal direction of the plate surface from the plate-like engaging portion 41 so that this portion functions as a hook portion (first corner portion) 42a. It has become.

  Similar to the knob 31 of the power switch 30, such a switch lever 40 can move in the lateral direction shown in FIG. Further, as shown in FIG. 3A, in the switch lever 40, the operation portion 42 (a part) protrudes from the resin case 10 when the knob 31 is in the blocking position P <b> 2. The amount of protrusion can be set as appropriate. For example, the protrusion amount may be approximately 1.5 mm from the side surface of the resin case 10. On the other hand, as shown in FIG. 3B, when the knob 31 is at the supply position P <b> 1, the switch lever 40 is in a state where the operation portion 42 is pushed into the resin case 10 and faces the resin case 10. Become one.

  FIG. 5 is an enlarged view of the switch lever 40 shown in FIG. 3 and its peripheral configuration. FIG. 5A shows the first state, and FIG. 5B shows the second state. First, as shown in FIG. 5A, when the knob 31 is in the blocking position P <b> 2, the hook portion 41 d of the engaging portion 41 is in contact with the resin case 10. Similarly, as shown in FIG. 5B, when the knob 31 is at the supply position P <b> 1, the hook part 42 a of the operation part 42 is in contact with the resin case 10. For this reason, the switch lever 40 is movable only between the supply position P1 and the blocking position P2 of the knob 31. Needless to say, some clearance may be provided in the above.

  In addition, in this embodiment, as shown in FIG. 3B, when the position of the knob 31 is at the supply position P1, the escape recess 41b comes into contact with the boss 11a. Thereby, excessive movement of the switch lever 40 to the inside of the resin case 10 is further restricted.

  FIG. 6 is a rear view of the battery-type gas alarm device 1 shown in FIGS. 1 and 2, wherein (a) shows a first state and (b) shows a second state. As shown in FIGS. 6A and 6B, the resin case 10 (rear case 12) has a second opening 10 b that is an opening that penetrates the rear case 12.

  As shown in FIG. 6B, the second opening 10b is switched when the operation portion 42 of the switch lever 40 is pushed into the resin case 10 and the position of the knob 31 is switched to the supply position P1. The end portion 41e of the lever 40 opposite to the operation portion 42 is exposed. When the position of the knob 31 is switched to the blocking position P2, the end 41e may be exposed from the second opening 10b or may not be exposed. In the example shown in FIG. 6A, the end portion 41e is exposed (very slightly) in consideration of operability.

  Furthermore, in this embodiment, the battery-type gas alarm device 1 further includes a breakable film-like seal 50 that covers the second opening 10b. Such a seal 50 is not affixed in a process where there is an opportunity to turn on / off the power in the manufacturing process, and is affixed so as to cover the second opening 10b in a subsequent process, or attached to each household. Sometimes it is pasted to cover the second opening 10b.

  Next, how the battery-type gas alarm device 1 according to this embodiment is turned on / off will be described. First, in a manufacturing process in a factory or the like, there is an opportunity to turn the power on and off relatively. First, assuming that the power source of the battery-type gas alarm device 1 is off, the battery-type gas alarm device 1 is in the state shown in FIGS. 3 (a), 5 (a), and 6 (a).

  In this state, when the operating portion 42 of the switch lever 40 is pushed into the resin case 10, the switch lever 40 switches the position of the knob 31 to the supply position P1, as shown in FIG. Thereby, the battery-type gas alarm device 1 will be in the state shown in FIG.5 (b) and FIG.6 (b). In this case, since the hook portion 42a and the relief recess 41b are in contact with the resin case 10 in the switch lever 40, it is possible to prevent a situation in which the switch lever 40 enters the resin case 10 and cannot be operated thereafter.

  On the other hand, when it becomes necessary to turn off the power source of the battery-type gas alarm device 1, an operator or the like uses a pointed object such as a ballpoint pen or a needle and inserts it into the second opening 10b. Then, the end 41 e of the switch lever 40 exposed from the second opening 10 b is moved in the direction of the operation unit 42. Thereby, as shown to Fig.3 (a), the switch lever 40 will switch the position of the knob 31 to the interruption | blocking position P2. And the battery-type gas alarm 1 will be in the state shown to Fig.5 (a) and Fig.6 (a).

  In this case, the switch lever 40 can prevent the switch lever 40 from jumping out of the resin case 10 because the hook portion 41d contacts the resin case 10.

  In addition, since there is an opportunity to turn the power on or off in a factory or the like, the seal 50 is affixed, for example, in the last step or when the alarm device 1 is attached to each household. Here, the sticking action of the seal 50 is preferably performed in a factory at the time of production. Thereby, without leaving the application to a worker on site, there is no forgetting to attach, or the frequency of forgetting to attach becomes extremely low.

  Next, a state when the battery-type gas alarm device 1 according to the present embodiment is attached to each household and then used by a user will be described. First, from the viewpoint of battery life, the knob 31 of the power switch 30 is in the cutoff position P2 when the battery-type gas alarm device 1 is shipped.

  Thereafter, the installer operates to push the operation portion 42 of the switch lever 40 into the resin case 10. Thereby, as shown in FIG.3 (b), the knob 31 moves to the supply position P1. The power switch 30 has a structure in which the knob 31 is difficult to stop between the supply position P1 and the shut-off position P2, and when the knob 31 passes an intermediate position between the supply position P1 and the shut-off position P2, the power switch 30 The knob 31 is assisted to move to positions P1 and P2 toward the near side.

  Thereafter, the installer attaches the battery-type gas alarm device 1 to the wall surface using a screw or the like.

  Thereafter, for example, when the battery-type gas alarm device 1 detects an abnormal state and outputs an alarm, even if the user tries to turn off the power, the operation unit 42 is flush with the resin case 10, and Since the seal 50 is attached to the second opening 10b, the user cannot turn off the power at first glance, and the user cannot easily turn off the power switch 30.

  Here, in the battery-type gas alarm device 1 described above, false alarms due to so-called malfunction may continue to be output. For example, the gas sensor may deteriorate in a direction that is easy to alarm due to the effects of miscellaneous gases such as seasonings used in cooking, vinegar, alcohol, water vapor, oil, etc. and temperature. There is a case where the alarm is given even though the concentration is not to be alarmed. In addition, the sensor circuit may be short-circuited due to the effects of miscellaneous gases such as seasonings used in cooking, vinegar, alcohol, water vapor, oil, etc., and temperature. In such cases, gas leaks. Even without it, you may be alerted. Furthermore, when there is a defect in the soldering of the wiring board 20, the sensor circuit or the like may be opened due to the influence of temperature or the like. In such a case, even if no gas leaks, An alarm may occur. As described above, the battery-type gas alarm device 1 may continue to output false alarms.

  In such a case, the user of the battery-type gas alarm device 1 informs the gas company by telephone, and the gas company is dispatched to the user. In the battery-type gas alarm device 1 according to the present embodiment, an instruction is given to perform the following operation or the like by telephone or the like in order to stop the false alarm between the dispatch and arrival.

  First, the gas company prompts the user to prepare a pointed object such as a ballpoint pen or a needle. Next, the gas company refers to the back of the case, and prompts the pen 50, the needle, etc. to pierce the seal 50.

  Next, the gas company prompts the user to move a ballpoint pen, a needle, or the like to the blocking position P2. As a result, the knob 31 of the power switch 30 is moved from the supply position P1 to the blocking position P2 while breaking the seal 50.

  As a result, the false alarm caused by the malfunction is stopped. Note that the second opening 10b is covered with the seal 50 at the time of occurrence of the false alarm. For this reason, the user who sees the case back part of the battery-type gas alarm device 1 can prevent the end 41e of the switch lever 40 from being confirmed by the seal 50, and can prevent the power from being turned off without permission. .

  Thus, according to the battery-type gas alarm device 1 according to the present embodiment, when the knob 31 is at the cutoff position P2, the operation portion 42 of the switch lever 40 is pushed into the resin case 10, The position of the knob 31 is switched to the supply position P1. For this reason, in the manufacturing process, the manufacturing side can set the knob 31 of the power switch 30 to the supply position P <b> 1 by pushing the operation unit 42. In addition, in this case, since the operation unit 42 is pushed into the resin case 10, it is not easy for the user to pull out the operation unit 42.

  Further, the resin case 10 is formed with a second opening 10b that exposes the end 41e opposite to the operation part 42 of the switch lever 40 when the position of the knob 31 is switched to the supply position P1. Yes. For this reason, the operation part 42 can be returned to a protrusion state by operating the opposite side edge part 41e of the switch lever 40 exposed from the 2nd opening part 10b. That is, the knob 31 of the power switch 30 can be set to the cutoff position P2. Here, when the operation part 42 protrudes from the resin case 10, the normal user may recognize that the operation part 42 is any switch and operate it, but the second opening 10 b is opposite to the switch lever 40. Even if the end 41e is exposed, it is not recognized that the knob 31 can be set to the blocking position P2 by operating this, and only the manufacturing side in the normal production process sets the knob 31 to the blocking position P2. I can't.

  As described above, the manufacturing side can be configured such that the power switch 30 can be turned on and off, and the user cannot easily turn the power switch 30 off.

  Further, since the film-like seal 50 that can be broken to cover the second opening 10b is further provided, the seal 50 can be pasted so as to cover the second opening 10b at the time of shipment or when the alarm device 1 is attached to each home. In this case, the user cannot visually recognize the opposite end 41e of the operation portion 42 of the switch lever 40 from the second opening 10b. For this reason, it is possible to further prevent the user from turning off the power switch 30 by operating the opposite end portion 41e of the switch lever 40. In addition, since the seal 50 can be broken, for example, when an alarm continues to sound due to a malfunction, the user presses the pen on the film-like seal 50 according to a telephone instruction from a gas company or the like. The knob 31 can be moved to the blocking position P2 simply by breaking it using a tip or a needle.

  Further, when the operation part 42 is pushed into the resin case 10 and the position of the knob 31 is switched to the supply position P1, the hook part 42a comes into contact with the resin case 10, so that the operation part 42 is more than expected. For example, a situation in which the knob 31 of the power switch 30 is destroyed due to being pushed into the case 10 can be prevented.

  Further, when the operation portion 42 is returned to the state protruding from the resin case 10 and the position of the knob 31 is set to the blocking position P2, the hook portion 41d contacts the resin case 10, so that the operation portion 42 is more than expected. It is possible to prevent a situation in which the switch lever 40 is detached, for example, by protruding from the resin case 10.

  As described above, the present invention has been described based on the embodiment, but the present invention is not limited to the above embodiment, and may be modified without departing from the gist of the present invention.

  For example, when the knob 31 is located at the supply position P1, the operation unit 42 is flush with the resin case 10. However, the operation unit 42 is not limited to this and is located inside the resin case 10. It may be.

  Moreover, in the said embodiment, although the 1st opening part 10a is provided in the side part of the resin case 10, it is not restricted to this, You may provide in other positions, such as a front surface or a back surface. Further, the second opening 10b is not limited to the back surface, and may be provided at other positions such as the front surface and the side portion.

  Further, the seal 50 may be provided with a perforation so that the user can easily break it, and a dot-like mark is printed so that a place where the user pierces with a needle or the like becomes clear. May be. In addition, the seal 50 may have a structure that is melted or torn by a liquid such as water, or may be other.

  In addition, in the present embodiment, when the knob 31 of the power switch 30 is in the blocking position P2, only a part of the operation part 42 protrudes from the side part of the resin case 10, but this is not restrictive, and more protrusions occur. The configuration may be such that the amount is increased and the engaging portion 41 protrudes in addition to the operation portion 42. In this case, a part of the operation part 42 and the engaging part 41 will function as a protruding part.
