The power supply unit 16 may be configured to be supplied with power from the outside of the gas detection device 1. For example, the power supply unit 16 may receive power from an external AC power source by using the plug 22 of the plug unit 20. Therefore, as shown in FIG. 1, in the plug unit 20, the plug 22 may be connected to the power supply unit 16 of the gas sensor 10 via the cable 24. As will be described later, the plug 22 can receive electric power from the plug receiver 42 by being plugged and connected to the plug receiver 42 of the socket portion 40. Thus, in one embodiment, the plug 22 is plugged into the plug receiver 42.

As shown in FIG. 1, the cable 24 that supplies power to the gas sensor 10 may be partially combined with the tube-shaped member 26 described above. In one embodiment, the cable 24 electrically connects the gas sensor 10 and the socket portion 40. Further, in one embodiment, the tubular member 26 leads the purge gas from the socket portion 40 to the gas sensor 10. Therefore, by partially bundling (bunching) the cables 24 with the tubular members 26, it is possible to prevent them from being entangled with each other.

The power supply unit 16 may be configured to appropriately include, for example, a converter that converts AC power received from an external AC power source into DC power. Further, the power supply unit 16 may include a rechargeable battery. In this case, the gas detection device 1 can charge the battery of the power supply unit 16 by inserting the plug 22 into the plug receiver 42. Further, the gas detection device 1 can be operated by the battery of the power supply unit 16 even if the plug 22 is removed from the plug receiver 42 after charging the battery of the power supply unit 16.

The pump 18 sucks the sample gas into the gas chamber 12 from the gas suction unit 3 through the gas introduction pipe 5. Any pump 18 may be adopted as long as the gas can be sent from one to the other. The pump 18 may be any pump such as a diaphragm pump. Further, the pump 18 may suck the purge gas into the gas chamber 12 via the tubular member 26 as described later. Further, the pump 18 may be configured by using a valve or the like. In one embodiment, one pump 18 may be used, or one or more pumps 18 may be used for each of the gas introduction pipe 5 and the tubular member 26.

As described above, the gas detection device 1 may include, for example, a gas suction unit 3, a gas sensor 10, an insertion plug 22, and a tubular member 26. Further, in the gas detection device 1, the plug 22 is configured to receive electric power from the plug receiver 42 while the plug 22 is inserted into the plug receiver 42. Along with receiving such electric power, in the gas detection device 1, the tubular member 26 is configured to be able to suck purge gas from the hole 62 in a state where the plug 22 is inserted into the plug receiver 42.

(Plug part)
Next, the plug portion according to the embodiment will be further described. As described above, the plug portion 20 may be included in the gas detection device 1. Further, as described above, the plug portion 20 is connected to a socket such as the socket portion 40. Specifically, the plug 22 in the plug portion 20 is inserted into, for example, the plug receiver 42 in the socket portion 40. The plug 22 in the plug portion 20 may be inserted into a plug receiver other than the plug receiver 42 in the socket portion 40. The plug portion 20 can have various configurations according to the required application and specifications. In the present disclosure, a typical example of the plug portion 20 according to the embodiment will be described, but the plug portion 20 according to the embodiment is not limited to the typical example in the present disclosure.

As shown in FIG. 1, the plug portion 20 may include a plug 22, a cable 24, and a tubular member 26.

As described above, the plug 22 may be plugged into the plug receiver 42 in the socket portion 40. As the plug 22, various conventionally known plugs may be adopted. For example, the plug 22 may be standardized in, for example, JIS C 8303-1993. For example, the plug 22 may be a general household 100V outlet (2-pole outlet 15A 125V standardized in JIS C 8303) parallel type. However, the plug 22 is not limited to the above-mentioned type, and may be another type of plug.

As shown in FIG. 1, the tubular member 26 sucks purge gas from the socket portion 40 through the hole 62. As described above, the purge gas sucked through the tubular member 26 may be supplied to the gas chamber 12 in the gas sensor 10. The tubular member 26 may be made of various materials such as synthetic resin. The tubular member 26 may be made of any material from which the purge gas can be derived. As will be described later, the tubular member 26 is connected to or inserted into the hole 62 to suck the purge gas through the hole 62 penetrating the surface 60 of the wall on which the plug receiver 42 of the socket portion 40 is installed. Can be done. The tubular member 26 may be made of a bendable material for connecting or inserting into the hole 62. As described above, in one embodiment, the tubular member 26 sucks gas from the hole 62 penetrating the surface 60 on which the plug receiver 42 is installed.

As described above, the wiring plug connector (plug portion 20) may be configured to include the plug 22 and the tubular member 26. Further, the plug portion 20 is configured so that the plug 22 receives electric power from the plug receiver 42 while the plug 22 is inserted into the plug receiver 42. Along with the supply of such electric power, the plug portion 20 is configured such that the tubular member 26 can suck gas from the hole 62.

(Socket part)
Next, the socket portion according to the embodiment will be described. As described above, the socket portion 40 is connected to the plug of an electronic device such as the gas detection device 1. Specifically, for example, the plug 22 in the plug portion 20 of the gas detection device 1 is inserted into the plug receiver 42 in the socket portion 40. A plug of an electronic device other than the gas detection device 1 may be inserted into the plug receiver 42 of the socket portion 40. The socket portion 40 can have various configurations according to a required application, specifications, and the like. Hereinafter, a typical example of the socket portion 40 according to the embodiment will be described, but the socket portion 40 is not limited to the following typical example.

As shown in FIG. 1, the socket portion 40 may be configured to include a plug receiver 42 and a hole 62. Further, as shown in FIG. 1, the socket portion 40 may include the pump 44. Further, as shown in FIG. 1, the socket portion 40 may include a cover plate 46.

As described above, the plug receiver 42 of the socket portion 40 may be installed on the wall surface (surface 60). The surface 60 may be, for example, a surface of a wall forming a side surface of the room. As shown in FIG. 1, the surface 60 may separate the space S1 and the space S2 at least partially. As described above, in one embodiment, the wall surface (surface 60) on which the plug receiver 42 is installed may at least partially separate the space communicated through the hole 62.

Here, the space S1 may be, for example, an internal space of a room defined by a surface 60 (usually a space in which a person or the like lives). In one embodiment, the space S1 may be a space (room or the like) in which the gas detection device 1 is used. In this case, the space S2 may be, for example, a space behind the wall forming the surface 60 (usually, a space in which no person or the like lives). That is, in this case, the space S2 may be a space formed between the wall forming the surface 60 and the outer wall of the building. In one embodiment, the space S2 may be a space (room or the like) in which the gas detection device 1 is not used. In this way, the wall forming the surface 60 separates the space S1 and the space S2 at least partially.

The plug receiver 42 may be inserted with the plug 22 of the plug portion 20. As described above, in one embodiment, the plug 22 is inserted into the plug receiver 42. As the plug receiver 42, various conventionally known plug receivers may be adopted. For example, the plug receiver 42 may be standardized in, for example, JIS C 8303-1993. However, the plug receiver 42 is not limited to the above-mentioned type, and may be another plug receiver.

As shown in FIG. 1, the plug receiver 42 receives electric power from, for example, a grid. The plug receiver 42 may receive power from, for example, a power cable wired on the back side of the wall. With such wiring, the plug receiver 42 can supply electric power to the plug 22 when the plug 22 is inserted. The plug receiver 42 may receive electric power from the outside such as a grid, depending on an arbitrary configuration.

As shown in FIG. 1, the hole 62 penetrates a surface 60 formed of, for example, a wall. Here, the plug receiver 42 of the socket portion 40 is installed on the surface 60. Thus, in one embodiment, the hole 62 penetrates the surface 60 on which the plug receiver 42 is installed. The hole 62 does not necessarily have to penetrate the wall forming the surface 60. For example, the hole 62 may penetrate the plug receiver 42 instead of directly penetrating the wall constituting the surface 60. In this case as well, the hole 62 penetrates the surface 60 on which the plug receiver 42 is installed. As shown in FIG. 1, in the socket portion 40, the hole 62 may be configured so that a lead-out tube such as a tubular member 26 can be connected or inserted.

As shown in FIG. 1, the hole 62 to which the outlet pipe such as the tubular member 26 is connected or inserted can supply the purge gas to the gas sensor 10 via the outlet pipe such as the tubular member 26. Various mechanisms may be adopted for the mechanism in which the hole 62 leads out the purge gas in the socket portion 40.

For example, the gas existing inside the housing of the socket portion 40 (for example, indicated by the broken line in FIG. 1) may be taken out as a purge gas to a lead-out pipe such as the tubular member 26. Further, a lead-out tube such as the tubular member 26 may be configured to lead to the outside of the housing of the socket portion 40. In this case, the gas existing outside the housing of the socket portion 40 may be led out to an outlet pipe such as the tubular member 26 as a purge gas. Further, the gas existing outside the housing of the socket portion 40 may be guided to the inside of the housing of the socket portion 40. In this case, the gas existing inside the housing of the socket portion 40 may be led out to an outlet pipe such as the tubular member 26 as a purge gas. In short, the socket portion 40 may take out the gas existing on the space S2 side as a purge gas to a lead-out pipe such as the tubular member 26.

In any of the above examples, the gas existing on the space S2 side can be supplied to the space S1 side as a purge gas. The sample gas used by the gas detection device 1 for detection is supplied from the space S1 side. As described above, the space S1 and the space S2 are separated at least partially. Therefore, according to the gas detection device 1 according to the embodiment, it is possible to prevent the sample gas from being mixed into the purge gas supplied to the gas detection device 1. Therefore, the gas detection device 1 according to the embodiment can satisfactorily detect at least one of the type and concentration of the gas contained in the sample gas based on the sample gas and the purge gas.

The pump 44 leads the purge gas to the tubular member 26. As a result, the pump 44 can draw the purge gas from the hole 62. Any pump 44 may be used as long as the gas can be sent from one to the other. The pump 44 may be any pump, such as a diaphragm pump. As described above, the socket portion 40 according to the embodiment may include a pump 44 that draws gas from the hole 62.

Further, in one embodiment, the socket portion 40 may be omitted without providing the pump 44. In this case, one or more pumps 18 of the gas sensor 10 may suck the purge gas into the tubular member 26. That is, the pump 18 may suck the purge gas into the gas chamber 12 via the tubular member 26. As described above, in one embodiment, the pump 18 for sucking gas from the hole 62 may be provided. In this case, the pump 18 may be provided, for example, at the tip of the tubular member 26. Here, the tip end portion of the tubular member 26 may be a portion connected or inserted into the hole 62 of the tubular member 26, or a portion near the portion.

As shown in FIG. 1, the cover plate 46 may be attached to a wall or the like constituting the surface 60. By attaching the cover plate 46 to a wall or the like constituting the surface 60, the entire plug receiver 42 can be prevented from being exposed to the space S1 inside the room where the gas detection device 1 is used. The cover plate 46 may be a mere design member. Further, in one embodiment, the socket portion 40 may be omitted without providing the cover plate 46. The cover plate 46 may be a member for fixing the plug receiver 42 to a wall or the like constituting the surface 60. That is, the plug receiver 42 may be configured to be fixed to the cover plate 46, and the cover plate 46 may be configured to be fixed to a wall or the like forming the surface 60. In this case, it is not necessary to directly fix the plug receiver 42 to the wall or the like constituting the surface 60.

As described above, the wiring plug connector (socket portion 40) may be configured to include the plug receiver 42 and the hole 62. Further, the socket portion 40 according to one embodiment is configured to supply electric power from the plug receiver 42 to the plug 22 in a state where the plug 22 is inserted into the plug receiver 42. Along with such power supply, the socket portion 40 is configured to be able to take out gas from the outlet pipe connected to the hole 62 in a state where the plug 22 is inserted into the plug receiver 42.

(Connection of plug-in connector for wiring)
Next, the connection between the plug portion 20 of the gas detection device 1 and the socket portion 40 of the plug-in connector for wiring will be further described.

For example, assume a situation where a user in the space S1 uses the gas detection device 1. When using the gas detection device 1, the user inserts the plug 22 of the plug portion 20 of the gas detection device 1 into the plug receiver 42 of the socket portion 40. As a result, the gas detection device 1 can receive electric power. Next, the user connects or inserts a lead-out tube such as a tubular member 26 into the hole 62 of the socket portion 40. As described above, the hole 62 may be configured so that, for example, a tubular member 26 can be connected or inserted.

FIG. 2 is a diagram schematically showing the appearance of the socket portion 40 according to the embodiment. FIG. 2 is an enlarged view of the socket portion 40 shown in FIG. FIG. 2 shows a state viewed in the direction in which the plug portion 20 is inserted into the socket portion 40. That is, FIG. 2 shows a state in which the socket portion 40 is viewed from the space S1 side shown in FIG.

FIG. 2 shows an example in which the cover plate 46 is installed on a wall or the like forming the surface 60 in the socket portion 40. Further, FIG. 2 shows a state in which a part of the plug receiver 42 is exposed from the cover plate 46.

The socket portion 40 shown in FIG. 2 is provided with two plug receivers 42. In one embodiment, the socket portion 40 may include one or more plug receivers 42 of any number. Two plugs 22 of the plug portion 20 as shown in FIG. 1 can be inserted into the plug receiver 42 shown in FIG.

The cover plate 46 of the socket portion 40 shown in FIG. 2 is formed with notches matching the holes 62. The upper hole 62A is located corresponding to the upper plug receiver of the two plug receivers 42. Further, the lower hole 62B is located corresponding to the lower plug receiver of the two plug receivers 42.

For example, the tubular member 26 of the plug portion 20A as shown in FIG. 3 may be inserted into the upper hole 62A shown in FIG. FIG. 3 is a diagram schematically showing the configuration of the plug portion 20A according to the embodiment. The plug portion 20A shown in FIG. 3 includes a plug 22, a cable 24, and a tubular member 26, similarly to the plug portion 20 shown in FIG.

For example, when using the gas detection device 1, the user inserts the plug 22 of the plug portion 20A shown in FIG. 3 into the upper plug receiver 42 of the two plug receivers 42 of the socket portion 40 shown in FIG. It's fine. Then, the user may insert the tip of the lead-out tube such as the tubular member 26 of the plug portion 20A shown in FIG. 3 into the hole 62A of the socket portion 40 shown in FIG.

As described above, in one embodiment, the outlet pipe for drawing out the gas from the hole 62 may be configured to be insertable into the hole 62. In one embodiment, the outlet pipe for leading out the gas from the hole 62 may be, for example, a tubular member 26. In this case, in one embodiment, the tubular member 26 may be configured to be insertable into the hole 62.

A connection terminal 64 attached to the tubular member 26 of the plug portion 20B as shown in FIG. 4, for example, may be connected to the lower hole 62B shown in FIG. FIG. 4 is a diagram schematically showing the configuration of the plug portion 20B. The plug portion 20B shown in FIG. 4 includes a plug 22, a cable 24, and a tubular member 26, similarly to the plug portion 20A shown in FIG. Unlike the plug portion 20A shown in FIG. 3, the plug portion 20B shown in FIG. 4 is provided with a connection terminal 64 at the tip end portion of the tubular member 26. As the connection terminal 64, any tube connector or the like capable of connecting the tubular member 26 to the hole 62B may be adopted. Further, as the connection terminal 64, any tube connector or the like capable of connecting the ends of the tubular member 26 or the like may be adopted.

For example, when using the gas detection device 1, the user inserts the plug 22 of the plug portion 20B shown in FIG. 4 into the lower plug receiver 42 of the two plug receivers 42 of the socket portion 40 shown in FIG. It's fine. Then, the user may connect the connection terminal 64 provided in the lead-out tube such as the tubular member 26 of the plug portion 20B shown in FIG. 4 to the hole 62B of the socket portion 40 shown in FIG. In FIGS. 2 and 4, an example in which the connection terminal 64 is provided at the tip of the tubular member 26 is shown. However, for example, the tip of the tubular member 26 shown in FIG. 4 may not be provided with the connection terminal 64, and the hole 62B shown in FIG. 2 may be provided with the connection terminal 64.

When the connection terminal 64 of the plug portion 20B shown in FIG. 4 is connected to the hole 62B of the socket portion 40 shown in FIG. 2, the back side of the hole 62B shown in FIG. 2, that is, the socket portion 40 shown in FIG. Various configurations may be adopted for the inside (indicated by a broken line). For example, inside the socket portion 40 shown in FIG. 1, nothing may be installed on the back side portion of the hole 62. In this case, the gas existing inside the socket portion 40 indicated by the broken line can be led out to the space S1 side through the hole 62. Further, in this case, for example, the pump 44 may introduce the gas on the space S2 side into the socket portion 40 indicated by the broken line. Further, for example, in the socket portion 40 shown in FIG. 1, a tubular member or the like may be provided from the hole 62 to the outside of the socket portion 40 shown by the broken line. In this case, the gas existing on the space S2 side can be led out to the space S1 side through the hole 62.
