[0011] The embodiments and modifications described below are merely examples of the present disclosure. The present disclosure is not limited to the embodiments and modifications, and various modifications other than these embodiments and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure. The drawings described in the following embodiments and modifications are schematic drawings, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0012] (1) Embodiment 1 (1-1) Overview An outline of the main body system 200 according to the first embodiment will be described below with reference to FIGS.

[0013] The main body system 200 according to the first embodiment is capable of attaching and detaching a cartridge substrate 10 provided with a sensitive part 11 whose electrical characteristic value changes in response to one or more types of molecules. Note that the "electrical characteristic value of the sensitive part 11" referred to in the present disclosure is, for example, electrical resistance, or a current value or voltage value corresponding to the electrical resistance.

[0014] The main body system 200 of the first embodiment includes an adapter 3, a second connection unit 21, an acquisition unit 231, a main body board 29, and a housing 20, as shown in FIGS.

[0015] The adapter 3 has a first connection portion 31. The adapter 3 is attached to the second connection portion 21, which is electrically connected to the first connection portion 31. The acquisition portion 231 is electrically connected to the second connection portion 21. The main body board 29 is provided with the acquisition portion 231. The housing 20 has a partition 28 that divides the internal space X1 into a first space X11 and a second space X12. The main body board 29 is housed in the second space X12.

[0016] In an attached state in which the cartridge substrate 10 is attached to the main body system 200, the cartridge substrate 10 is attached to the first connection part 31, and the acquisition part 231 is electrically connected to the sensitive part 11 via the first connection part 31, the adapter 3, and the second connection part 21 to acquire the electrical characteristic value of the sensitive part 11. Furthermore, in the above-mentioned attached state, at least a part of the cartridge substrate 10 is accommodated in the first space X11, and one or more types of molecules (including a sample gas described below) flow into the first space X11.

[0017] In the above-described wearing state, the main body system 200 of the first embodiment functions as part of the air quality evaluation system 100 (see FIG. 2). The air quality evaluation system 100 is used, for example, to detect odor molecules as detection target molecules. The detection target odor molecules may include, for example, volatile organic compounds (VOCs) such as benzaldehyde, nonanal, and pyrrol, which are contained in human body odor components, as well as ammonia.

[0018] The air quality evaluation system 100 detects VOCs, which are odor molecules contained in sample gases such as gases containing body odor collected from the body of a subject or exhaled breath, or air collected from a room in a building. Note that the molecules to be detected by the air quality evaluation system 100 are not limited to VOCs, and multiple types of odor molecules including VOCs may be detected.

[0019] The air quality assessment system 100 can be used to assess the health status of a subject by evaluating the air quality of a sample gas, such as a gas containing body odor collected from the subject's body or exhaled breath. If the subject is a driver of a vehicle such as a car, train, airplane, or ship, the air quality assessment system 100 can be used to assess the driver's fatigue level or alertness by evaluating the air quality of the sample gas. The air quality assessment system 100 can also perform biometric authentication by evaluating the air quality of the sample gas collected from the subject, or can be used to search for rescue recipients trapped under rubble at disaster sites by detecting gas containing body odor or exhaled breath emitted by such recipients. The sample gas is not limited to gas (such as exhaled breath) emitted from the human body. The air quality assessment system 100 can also be used to control the quality of food by detecting the presence or absence of gas emitted during food spoilage. The air quality evaluation system 100 may also evaluate the state of air quality in a room by detecting the presence or absence of VOCs emitted from building materials in the room, etc. The air quality evaluation system 100 may also evaluate the presence or absence of gases generated by fire, gases emitted from explosives or drugs, or toxic gases.

[0020] In the main body system 200 of the first embodiment, the housing 20 has a partition 28 that divides the internal space X1 into a first space X11 that accommodates at least a portion of the cartridge substrate 10 in the mounted state and into which one or more types of molecules flow, and a second space X12 that accommodates the main body substrate 29 in the mounted state. As a result, the main body system 200 of the first embodiment has the effect of suppressing deterioration of the main body substrate 29 due to exposure to sample gas containing one or more types of molecules. In other words, the main body system 200 of the first embodiment has the advantage of improving durability of the main body substrate 29, which is provided with an acquisition unit 231 that acquires electrical characteristic values ​​of the sensitive part 11.

[0021] (1-2) Detailed configuration (1-2-1) Air Quality Assessment System The detailed configuration of the air quality evaluation system 100 of the first embodiment will be described below with reference to FIGS.

[0022] As shown in FIG. 2 , the air quality evaluation system 100 includes a cartridge 1, a main body system 200, and an evaluation unit 412. The main body system 200 includes an adapter 3 and another main body system 200. The evaluation unit 412 evaluates the air quality state of the sample gas based on the pattern of change in the electrical characteristic value of the sensor unit 11 exposed to sample gas containing one or more types of molecules. Note that, in the present disclosure, "evaluating the air quality state of the sample gas" may refer to evaluating whether or not target molecules are present in the sample gas, in other words, whether or not target molecules exceed a predetermined concentration in the sample gas, or to evaluating the types of target molecules present in the sample gas. Furthermore, the number of target molecules to be detected is not limited to one type. When there are multiple types of target molecules to be detected, evaluating the air quality state may also refer to evaluating the presence or absence and concentration of each type of molecule. Furthermore, evaluating the air quality state may also refer to evaluating the odor quality of the sample gas (e.g., pleasant odor, unpleasant odor, etc.).

[0023] 2 and 3, the air quality evaluation system 100 of the first embodiment includes, in addition to the cartridge 1 and the device main body 2, an evaluation device 4, which has the above-mentioned evaluation unit 412. A more detailed configuration of the evaluation unit 412 will be described in the section "(1-2-4) Evaluation device."

[0024] In the first embodiment, the device main body 2 and the evaluation device 4 are electrically connected via a cable CB1. The cable CB1 is a cable that can supply power and communicate.

[0025] (1-2-2) Cartridge As shown in Figures 1, 2, and 4, the cartridge 1 of embodiment 1 comprises a cartridge substrate 10, a sensitive part 11, a heater part 12, a temperature sensor 13, a first connection terminal 14, a plurality of conductor parts 16, and a housing 17.

[0026] (Cartridge board) The cartridge substrate 10 is a flat plate-like member. More specifically, as shown in FIG. 4, the cartridge substrate 10 is a printed wiring board having first connection terminals 14, which are wiring patterns, and a plurality of conductor portions 16. As shown in FIG. 1, the cartridge substrate 10 has a first surface 101 and a second surface 102 that face each other in the thickness direction. More specifically, the first surface 101 is the upper surface of the cartridge substrate 10, and the second surface 102 is the lower surface of the cartridge substrate 10.

[0027] The cartridge substrate 10 is configured to be attachable to and detachable from a first connecting portion 31 (described later) of the adapter 3. More specifically, as shown in FIG. 1 , the cartridge 1 is inserted into the insertion port 27 of the device main body 2 so that the first connecting terminal 14 is positioned at the rear, and the cartridge substrate 10 is inserted into the first connecting portion 31, thereby attaching the cartridge substrate 10 to the first connecting portion 31 of the adapter 3. With the cartridge substrate 10 inserted into the first connecting portion 31, the first connecting terminal 14 of the cartridge substrate 10 is electrically connected to the first connecting portion 31. Meanwhile, when the cartridge 1 is removed from the insertion port 27 of the device main body 2 and the cartridge substrate 10 is removed from the first connecting portion 31, the cartridge substrate 10 is detached from the first connecting portion 31 of the adapter 3. In the cartridge 1 of embodiment 1, when the cartridge substrate 10 is attached to the first connection portion 31 of the adapter 3 and the adapter substrate 30 is attached to the second connection portion 21 of the device main body 2 described later, the cartridge 1 is driven by power supplied to the first connection terminal 14 from the power supply portion 44 of the evaluation device 4 described later via the device main body 2 and the adapter 3.

[0028] (sensing part) As shown in FIG. 4, a sensitive part 11 is provided on the first surface 101 of the cartridge substrate 10. The sensitive part 11 changes its electrical characteristic value in response to one or more types of molecules to which it is sensitive. In the first embodiment, as shown in FIGS. 4 and 5, the sensitive part 11 has a plurality of sensitive elements Ax (x is a natural number) with different sensitivity characteristics. In the first embodiment, the sensitive part 11 has 16 sensitive elements Ax, and hereinafter, each of the 16 sensitive elements Ax may be referred to as a sensitive element A1 to A16 (see FIG. 5). The 16 sensitive elements A1 to A16 are arranged in four rows and four columns on the flat cartridge substrate 10. The sensitive part 11 of the first embodiment is accommodated in the internal space X1 of the housing 17.

[0029] As shown in FIGS. 5 and 6, each of the multiple sensor elements Ax is formed into a film-like shape, including an organic composition 111 formed by molding an organic material into a disk shape and conductive particles 112 dispersed in the organic composition 111. When the sensor element Ax is exposed to a sample gas containing target molecules, the organic composition 111 absorbs the target molecules and expands. In FIG. 6, the left side of the figure shows the state of the sensor element Ax before absorbing the target molecules M1, and the right side shows the state of the sensor element Ax after absorbing the target molecules M1. When the sensor element Ax absorbs the target molecules M1, the organic composition 111 expands, and therefore, after the sensor element Ax absorbs the target molecules M1, the spacing between the conductive particles 112 becomes wider than before absorbing the target molecules M1, and the electrical resistance of the sensor element Ax increases. In the first embodiment, the target molecules are odor molecules such as benzaldehyde, nonanal, and pyrrole. In other words, the sensor element Ax has an organic composition 111 that is sensitive to odor molecules, and when the sensor part 11 is exposed to a sample gas containing odor molecules, the organic composition 111 expands by adsorbing the odor molecules, and the electrical resistance of the organic composition 111 increases.

[0030] The sensitive element Ax has temperature dependency, whereby its electrical characteristic value (electrical resistance) changes depending on the temperature. Here, the sensitive element Ax includes a sensitive element Ax having a positive resistance coefficient (hereinafter also referred to as a positive characteristic sensitive element) Ax, where the electrical resistance increases with increasing temperature, and a sensitive element Ax having a negative resistance coefficient (hereinafter also referred to as a negative characteristic sensitive element) Ax, where the electrical resistance decreases with increasing temperature.

[0031] In the first embodiment, the sensitive part 11 includes a negative characteristic sensitive element having a negative resistance coefficient in the temperature range of -20°C or higher and 50°C or lower, and the sensitive elements A1 to A11 correspond to the negative characteristic sensitive elements. The sensitive part 11 also includes a positive characteristic sensitive element having a positive resistance coefficient in the temperature range of -20°C or higher and 50°C or lower, and the sensitive elements A12 to A16 correspond to the positive characteristic sensitive elements. A heater control part 241 (described later) of the device main body 2 controls the temperature of the sensitive part 11 by passing a pulsed current through the heater part 12. By passing a pulsed current through the heater part 12, the temperature of the sensitive part 11 is controlled according to a temperature change pattern in which a temperature rise period in which the temperature of the sensitive part 11 rises and a temperature fall period in which the temperature of the sensitive part 11 falls are alternately repeated. Here, in response to the temperature change of the sensor unit 11, the temperature of the internal space X1 of the housing 17 also changes in a temperature change pattern in which a temperature rise period in which the temperature rises and a temperature fall period in which the temperature falls are alternately repeated. The length of the temperature rise period is the time required for the odor molecules to desorb, and is, for example, several tens of seconds, but this time can be changed as appropriate. The length of the temperature fall period is the time required for the fluctuations in the electrical characteristic values ​​due to the adsorption of the odor molecules to stabilize, and is, for example, several tens of seconds, but this time can be changed as appropriate.

[0032] The sensor element A1 is a negative-temperature-characteristic sensor element whose resistance decreases with increasing temperature. Therefore, when the temperature of the sensor element A1 is changed according to the temperature change pattern described above, the resistance of the sensor element A1 decreases with increasing temperature during the temperature rise period, and increases with decreasing temperature during the temperature fall period. Here, when the sensor element A1 is exposed to a sample gas containing odor molecules, the resistance decreases during the temperature rise period due to the desorption of odor molecules, and increases during the temperature fall period due to the absorption of odor molecules. Therefore, the resistance of the sensor element A1 changes with a variation due to temperature change superimposed on a variation due to the amount of odor molecules adsorbed by the sensor element A1.

[0033] Furthermore, the sensor element A16 is a positive temperature coefficient sensor element whose resistance increases with increasing temperature. Therefore, when the temperature of the sensor element A16 is changed according to the temperature change pattern described above, the resistance of the sensor element A16 changes in a pattern such that the resistance increases with increasing temperature during the temperature rise period and decreases with decreasing temperature during the temperature fall period. Here, when the sensor element A16 is exposed to a sample gas containing odor molecules, the resistance decreases during the temperature rise period due to the desorption of odor molecules, and increases during the temperature fall period due to the absorption of odor molecules. Therefore, the change pattern of the resistance of the sensor element A16 is a pattern in which the fluctuation due to temperature change (increase during the temperature rise period, decrease during the temperature fall period) is superimposed on the fluctuation due to the amount of odor molecules adsorbed by the sensor element A16.

[0034] (heater part) The heater unit 12 heats the sensor unit 11. More specifically, the heater unit 12 generates heat by passing an electric current through it under the control of a heater control unit 241 (described later) in the device main body 2, thereby heating the sensor unit 11. In the air quality evaluation system 100 of embodiment 1, the cartridge 1 is provided with the heater unit 12, which allows the heater unit 12 to heat the sensor unit 11 more stably than in the air quality evaluation system of the comparative example in which the device main body is provided with the heater unit. As a result, the sensor unit 11 has the advantage of being able to stably desorb odor molecules. In other words, the evaluation unit 412 of the air quality evaluation system 100 has the advantage of being able to stably evaluate the air quality state of the sample gas.

[0035] The heater section 12 of the first embodiment is provided by printing an exothermic ink material on the first surface 101 of the cartridge substrate 10. That is, the heater section 12 of the first embodiment is made of an exothermic ink material. This configuration has the advantage that the heater section 12 can be easily provided. Note that the "exothermic ink material" referred to here is an ink material that has the property of generating heat when an electric current is passed through it, such as an ink material whose main component is carbon. The "exothermic ink material" may also be a paste-like material whose main component is carbon. The exothermic ink material can be printed on the first surface 101 of the cartridge substrate 10 by, for example, screen printing, inkjet printing, or gravure printing, but the printing method is not limited thereto.

[0036] The heater unit 12 is provided on the first surface 101 of the cartridge substrate 10 so as to transfer heat directly to the sensitive unit 11. In the present disclosure, "direct transfer of heat" means that the heat generated by the heater unit 12 is transferred to the sensitive unit 11 without passing through any other components. Specifically, the heat generated by the heater unit 12 is transferred to the sensitive unit 11 through a gap provided to insulate the heater unit 12 from the sensitive unit 11. In other words, the heater unit 12 is provided so that no other components are disposed between the heater unit 12 and the sensitive unit 11. This configuration improves the efficiency with which the heat from the heater unit 12 is transferred to the sensitive unit 11. As a result, the sensitive unit 11 has the advantage of being able to efficiently desorb odor molecules. In other words, the evaluation unit 412 of the air quality evaluation system 100 has the advantage of being able to efficiently evaluate the air quality state of the sample gas.

[0037] As shown in FIG. 4, the heater unit 12 of the first embodiment is provided in a plate shape on the first surface 101 of the cartridge substrate 10, and has a plurality of openings so that each of the plurality of sensory elements Ax in the sensory unit 11 is exposed. That is, the heater unit 12 of the first embodiment is provided on the first surface 101 of the cartridge substrate 10 so as to surround the sensory unit 11. More specifically, the heater unit 12 of the first embodiment is provided on the first surface 101 of the cartridge substrate 10 so as to surround each of the plurality of sensory elements Ax in the sensory unit 11. This configuration improves the efficiency with which heat from the heater unit 12 is transferred to the sensory unit 11. As a result, the sensory unit 11 has the advantage of being able to more efficiently desorb odor molecules. That is, the evaluation unit 412 of the air quality evaluation system 100 has the advantage of being able to more efficiently evaluate the air quality state of the sample gas.

[0038] (Temperature sensor) The temperature sensor 13 is provided on the first surface 101 of the cartridge substrate 10 near the sensitive portion 11. As shown in FIG. 5, the temperature sensor 13 in embodiment 1 is provided on the first surface 101 of the cartridge substrate 10 in the center of the range in which the multiple sensitive elements Ax are provided in the sensitive portion 11. More specifically, the temperature sensor 13 in embodiment 1 is provided between the sensitive elements A6, A7 and the sensitive elements A10, A11 in the front-rear direction. The temperature sensor 13 is a sensor for detecting the temperature of the sensitive portion 11, and in embodiment 1, the temperature of the sensitive portion 11 is indirectly detected by detecting the temperature around the sensitive portion 11. The temperature sensor 13 is, for example, a thermistor.

[0039] (Connection terminal, conductor part) The first connection terminal 14 and the plurality of conductor portions 16 are a wiring pattern (for example, a pattern of copper foil or the like) provided on the first surface 101 of the cartridge substrate 10.

[0040] The first connection terminal 14 is electrically connected to the first connection portion 31 of the adapter 3 when the cartridge substrate 10 is attached to the first connection portion 31 of the adapter 3. As shown in FIG. 4, the first connection terminal 14 is provided at the rear end of the first surface 101 of the cartridge substrate 10. More specifically, as shown in FIG. 1, the first connection terminal 14 is provided at a portion of the first surface 101 of the cartridge substrate 10 that is not housed in the housing 17. The first connection terminal 14 has a plurality of electrodes aligned in the left-right direction.

[0041] Each of the plurality of conductors 16 is electrically connected to at least one of the plurality of electrodes in the first connection terminal 14. Each of the plurality of sensitive elements Ax, heater section 12, and temperature sensor 13 in the sensitive section 11 corresponds one-to-one to a combination of two of the plurality of conductors 16, and is electrically connected to the corresponding two conductors 16.

[0042] That is, when the cartridge substrate 10 is attached to the first connecting portion 31 of the adapter 3, the sensitive portion 11 is electrically connected to the first connecting portion 31 via the first connecting terminal 14 and the two corresponding conductor portions 16. Similarly, when the cartridge substrate 10 is attached to the first connecting portion 31 of the adapter 3, the heater portion 12 and the temperature sensor 13 are each electrically connected to the first connecting portion 31 via the first connecting terminal 14 and the two corresponding conductor portions 16.

[0043] 4, the heater section 12 of the first embodiment further includes two heater electrodes 121 and 122. The heater section 12 of the first embodiment is electrically connected to one of the two corresponding conductor sections 16 via the heater electrode 121, and is electrically connected to the remaining conductor section 16 via the heater electrode 122. The heater section 12 of the first embodiment is not electrically connected to the two conductor sections 16 corresponding to each of the multiple sensitive elements Ax in the sensitive section 11 and the two conductor sections 16 corresponding to the temperature sensors 13.

[0044] In the cartridge substrate 10 of the first embodiment, a protective layer 18 (see FIG. 4) that protects at least the plurality of conductor portions 16 is provided on the first surface 101. The protective layer 18 is provided between the plurality of conductor portions 16 and the plurality of sensitive elements Ax of the sensitive portion 11, the heater portion 12, and the temperature sensor 13 in the thickness direction of the cartridge substrate 10. The protective layer 18 covers from above the plurality of conductor portions 16 except for the portions that are electrically connected to the plurality of sensitive elements Ax of the sensitive portion 11, the heater portion 12, and the temperature sensor 13.

[0045] (Storage part) As shown in FIG. 2 , the cartridge 1 of the first embodiment further includes a memory unit 19 storing characteristic data related to the sensitivity of the electrical characteristic value of the sensitive part 11. The memory unit 19 is a memory circuit storing characteristic data, such as a RAM, a ROM, or an EEPROM. In the present disclosure, the “sensing characteristic of the electrical characteristic value of the sensitive part 11” refers to the characteristic of the change pattern of the electrical characteristic value (electrical resistance) when each of the multiple sensitive elements Ax of the sensitive part 11 reacts to one or more types of molecules. In other words, the “characteristic data related to the sensitivity of the electrical characteristic value of the sensitive part 11” refers to data indicating the characteristic of the change pattern of the electrical characteristic value (electrical resistance) when each of the multiple sensitive elements Ax of the sensitive part 11 reacts to one or more types of molecules. With the above configuration, the heater control unit 241 can control the power supplied to the heater unit 12 based on the characteristic data stored in the memory unit 19, i.e., the sensitivity of the electrical characteristic value of the sensitive part 11. As a result, the sensor 11 has the advantage of being able to desorb odor molecules based on the sensing characteristics of the electrical characteristic values ​​of the sensor 11. Furthermore, the acquisition unit 231 (described later) of the device main body 2 can acquire one cycle of pulse output from the sensor elements A1 to A16 based on the sensing characteristics of the electrical characteristic values ​​of the sensor 11. As a result, the evaluation unit 412 of the air quality evaluation system 100 has the advantage of being able to evaluate the state of air quality of the sample gas based on the sensing characteristics of the electrical characteristic values ​​of the sensor 11. Note that the memory unit 19 is omitted from the illustrations of FIGS. 1 and 4.

[0046] The characteristic data stored in the memory unit 19 includes data regarding the variation in the electrical characteristic values ​​of the sensor unit 11 under predetermined conditions. In the present disclosure, "data regarding the variation in the electrical characteristic values ​​of the sensor unit 11 under predetermined conditions" refers to data indicating the estimated variation in the change pattern of the electrical characteristic values ​​(electrical resistance) when each of the multiple sensor elements Ax of the sensor unit 11 reacts to one or more types of molecules under predetermined conditions. Note that the "predetermined conditions" here refer to pre-set conditions, specifically, pre-set conditions such as a temperature change pattern for controlling the temperature of the sensor unit 11 and the concentration of the sample gas to which the sensor unit 11 is exposed. With the above configuration, the heater control unit 241 can control the power supplied to the heater unit 12 based on the variation in the electrical characteristic values ​​of the sensor unit 11 under predetermined conditions. This provides the advantage that the sensor unit 11 can desorb odor molecules based on the variation in the electrical characteristic values ​​of the sensor unit 11 under predetermined conditions. Furthermore, the acquisition unit 231 of the device body 2, which will be described later, can acquire one cycle of pulse output from the sensor elements A1 to A16 based on the variation in the electrical characteristic value of the sensor part 11 under predetermined conditions. As described above, the evaluation unit 412 of the air quality evaluation system 100 has the advantage of being able to evaluate the state of the air quality of the sample gas based on the variation in the electrical characteristic value of the sensor part 11 under predetermined conditions.

[0047] (Housing) As shown in FIG. 1, the housing 17 accommodates the sensitive part 11 and at least a part of the cartridge substrate 10. The housing 17 of the first embodiment accommodates a part of the cartridge substrate 10 (a part of the cartridge substrate 10 excluding the part where the first connection terminal 14 is provided), the sensitive part 11, the heater part 12, the temperature sensor 13, and the plurality of conductor parts 16. On the other hand, the housing 17 of the first embodiment does not accommodate the part of the cartridge substrate 10 where the first connection terminal 14 is provided. That is, in the first embodiment, the part of the cartridge substrate 10, the sensitive part 11, the heater part 12, the temperature sensor 13, and the plurality of conductor parts 16 are accommodated in the internal space X1 of the housing 17 (see FIG. 1), and the first connection terminal 14 is not accommodated in the internal space X1 of the housing 17. The housing 17 of the first embodiment is shaped like a rectangular box. The housing 17 is made of a resin material, for example.

[0048] (1-2-3) Adapter As shown in FIGS. 1, 2, and 7, the adapter 3 includes an adapter substrate 30, a first connection portion 31, a plurality of conductor portions 32, and a second connection terminal 33.

[0049] (adapter board) The adapter board 30 is a flat member. In the first embodiment, as shown in Fig. 7, the adapter board 30 is a printed wiring board provided with a second connection terminal 33, which is a wiring pattern, and a plurality of conductors 32. In an attached state in which the cartridge board 10 is attached to the first connection portion 31 and the adapter board 30 is attached to the second connection portion 21 described below, the first connection portion 31 and the second connection portion 21 are electrically connected via the second connection terminal 33 and the plurality of conductors 32. This configuration has the advantage of simplifying the configuration of the adapter 3 compared to when the adapter includes a cable or the like.

[0050] 1, the adapter substrate 30 has a first surface 301 and a second surface 302 that face each other in the thickness direction. More specifically, the first surface 301 is the upper surface of the adapter substrate 30, and the second surface 302 is the lower surface of the adapter substrate 30.

[0051] (First connection part) The first connection portion 31 is configured to allow the cartridge substrate 10 of the cartridge 1 to be detachably attached. The cartridge substrate 10 is attached to the first connection portion 31 by inserting the cartridge substrate 10 inserted through the insertion port 27. On the other hand, the first connection portion 31 is detached from the cartridge substrate 10 by removing the inserted cartridge substrate 10 and pulling it out from the insertion port 27. The first connection portion 31 is electrically connected to each of the processing unit 23 and the control unit 24. As shown in FIG. 7 , the first connection portion 31 is provided at the front end of the first surface 301 of the adapter substrate 30.

[0052] When the cartridge substrate 10 is attached (in a state in which the cartridge substrate 10 is attached), the first connection portion 31 is electrically connected to each of the sensitive portion 11, the heater portion 12, and the temperature sensor 13. More specifically, when the cartridge substrate 10 is attached, the first connection portion 31 is electrically connected to the electrode of the first connection terminal 14 of the cartridge 1, and thereby electrically connected to each of the sensitive portion 11, the heater portion 12, and the temperature sensor 13 via the first connection terminal 14 and the multiple conductor portions 16. In other words, the first connection portion 31 is an interface that connects the cartridge 1 and the adapter 3. The first connection portion 31 is schematically illustrated in FIGS. 1, 3, and 7.

[0053] 1, in the first embodiment, the first connection portion 31 is located (exists) in the second space X12 of the housing 20 in an attached state in which the cartridge substrate 10 is attached to the first connection portion 31 and the adapter substrate 30 is attached to the second connection portion 21 of the device body 2. The second space X12 is a space into which sample gas containing one or more types of molecules is unlikely to flow, which has the effect of making the second connection portion 21 less likely to be exposed to one or more types of molecules. As a result, there is an advantage in that deterioration of the first connection portion 31 due to one or more types of molecules can be suppressed.

[0054] (Second connection terminal, conductor part) The second connection terminal 33 and the plurality of conductor portions 32 are a wiring pattern (for example, a copper foil pattern) provided on the first surface 301 of the adapter board 30.

[0055] The second connection terminal 33 is electrically connected to the second connection portion 21 when the adapter board 30 is attached to the second connection portion 21 of the device body 2. As shown in Fig. 7, the second connection terminal 33 is provided at the rear end portion of the first surface 101 of the adapter board 30. The second connection terminal 33 has a plurality of electrodes aligned in the left-right direction.

[0056] Each of the plurality of conductors 32 is electrically connected to at least one of the plurality of electrodes in the second connection terminal 33. Furthermore, each of the plurality of conductors 32 is electrically connected to the first connection portion 31. Each of the plurality of conductors 32 corresponds one-to-one to the plurality of electrodes in the first connection terminal 14 of the cartridge 1, and is electrically connected to the corresponding electrode of the first connection terminal 14 via the first connection portion 31 when the cartridge substrate 10 is attached to the first connection portion 31. In other words, when the cartridge substrate 10 is attached to the first connection portion 31, each of the plurality of electrodes in the first connection terminal 14 of the cartridge 1 is electrically connected to the corresponding electrode of the plurality of electrodes in the second connection terminal 33 of the adapter 3 via the first connection portion 31 and the corresponding conductor 32.

[0057] In the adapter board 30 of the first embodiment, a protective layer 39 (see FIG. 7) that protects at least the plurality of conductor portions 32 is provided on the first surface (predetermined surface) 301. The protective layer 39 covers the plurality of conductor portions 32 from above.

[0058] 1 and 7, in the first embodiment, the first connection portion 31 is provided at the front end of the adapter board 30, and the second connection terminal 33 is provided at the rear end of the adapter board 30. Therefore, as shown in Fig. 1, in an installed state in which the cartridge board 10 is attached to the first connection portion 31 and the adapter board 30 is attached to a second connection portion 21 (described later) of the device main body 2, the direction in which the cartridge board 10 is attached to the first connection portion 31 and the direction in which the adapter 3 is attached to the second connection portion 21 are the same front-rear direction (i.e., they do not intersect) when viewed from the thickness direction of the cartridge board 10.

[0059] (1-2-4) Device body 1 and 2, the device main body 2 includes a housing 20, a second connection unit 21, a fan 22, a processing unit 23, a control unit 24, a communication unit 25, and a main body board 29. The device main body 2 of the first embodiment is driven by power supplied from the evaluation device 4 via a cable CB1.

[0060] (Housing) The housing 20 accommodates the main body substrate 29 in an internal space X1. The housing 20 has a hollow rectangular box shape, as shown in Fig. 3. The housing 20 is made of, for example, a resin material.

[0061] As shown in FIGS. 1 and 3, an opening 26 is provided in the top plate 201 of the housing 20, and a fan 22 is disposed inside the opening 26. Here, the "top plate 201 of the housing 20" refers to the upper part of the housing 20. The opening 26 is connected to an internal space X1 of the housing 20. The internal space X1 of the housing 20 is connected to a space outside the housing 20 via the opening 26. When the fan 22 operates (rotates), the sample gas flows into the internal space X1 of the housing 20 (more specifically, a first space X11, which will be described later) via the opening 26. As shown in FIG. 3, the opening 26 has a circular shape when viewed from above.

[0062] Furthermore, a slot 27 into which the cartridge 1 is inserted is provided on a side surface (front side surface) of the housing 20. The slot 27 is connected to the internal space X1 (more specifically, the first space X11) of the housing 20. As shown in Fig. 3, the slot 27 has a rectangular shape in a side view.

[0063] In an attached state in which the cartridge substrate 10 of the cartridge 1 is attached to the first connecting portion 31 and the adapter substrate 30 of the adapter 3 is attached to the second connecting portion 21, the housing 20 accommodates at least a portion of the cartridge substrate 10 in the internal space X1. As shown in FIG. 1 , in the attached state, the housing 20 of the first embodiment accommodates the entire cartridge substrate 10 and the entire adapter substrate 30 in the internal space X1. More specifically, in the attached state, the housing 20 of the first embodiment accommodates a portion of the housing 17 of the cartridge 1 (more specifically, a portion of the housing 17 excluding the front end portion) and the adapter 3 in the internal space X1. In short, in the attached state, the housing 20 of the first embodiment accommodates the sensitive part 11 of the cartridge 1. That is, in the attached state, the sensitive part 11 of the cartridge 1 is disposed in the internal space X1 (more specifically, the first space X11) of the housing 20 of the device main body 2.

[0064] As shown in FIG. 1 , the internal space X1 of the housing 20 has a first space X11 and a second space X12, and the housing 20 has a partition 28 that separates the first space X11 from the second space X12. The first space X11 accommodates the entire cartridge substrate 10 and is a space into which a sample gas containing one or more types of molecules flows. On the other hand, the second space X12 accommodates the entire adapter substrate 30 and the entire main body substrate 29 and is a space into which a sample gas containing one or more types of molecules does not easily flow. In the first embodiment, the housing 20 has one partition 28.

[0065] The partition 28 in the first embodiment is a plate portion that protrudes inward (downward) from the inner surface (lower surface) of the top plate 201 of the housing 20. In the first embodiment, the tip (lower end) of the partition 28 does not contact the bottom plate 202 of the housing 20. That is, a gap into which the cartridge 1 and the adapter 3 are inserted is provided between the tip of the partition 28 and the bottom plate 202 of the housing 20. In short, in the first embodiment, the first space X11 and the second space X12 are not completely separated by the partition 28.

[0066] The partition 28 in embodiment 1 is provided between the opening 26 and the first connection portion 31 of the adapter 3 in the front-to-rear direction when the cartridge substrate 10 is attached to the first connection portion 31 and the adapter substrate 30 is attached to the second connection portion 21.

[0067] (Main board) The main substrate 29 is a flat member and is a printed wiring board on which a plurality of conductor portions 91, which are wiring patterns, are provided.

[0068] 1, the main substrate 29 has a first surface 291 and a second surface 292 that face each other in the thickness direction. More specifically, the first surface 291 is the upper surface of the main substrate 29, and the second surface 292 is the lower surface of the main substrate 29.

[0069] The plurality of conductors 91 are wiring patterns (for example, patterns of copper foil, etc.) provided on the second surface 292 of the main body substrate 29. Each of the plurality of conductors 91 corresponds one-to-one to a plurality of electrodes in the second connection terminal 33 of the adapter 3, and is electrically connected to the corresponding electrode of the second connection terminal 33 via the second connection portion 21 when the adapter substrate 30 is attached to the second connection portion 21.

[0070] Since the plurality of conductors 91 are provided on the second surface 292 of the main body substrate 29, the plurality of conductors 91 are less likely to be exposed to the sample gas containing one or more types of molecules that flows into the internal space X1 of the housing 20 through the opening 26. As a result, there is an advantage that the plurality of conductors 91 (i.e., the main body substrate 29) can be prevented from being deteriorated by one or more types of molecules.

[0071] An electronic component 92 is disposed on the second surface 292 of the main body substrate 29. The electronic component 92 has a circuit that processes or controls part of the operation of the air quality evaluation system 100. That is, the electronic component 92 functions as the processing unit 23 and the control unit 24. More specifically, the electronic component 92 reads and executes software stored in memory, thereby realizing part or all of the functions of the processing unit 23 and the control unit 24. As an example, the electronic component 92 is a so-called microcomputer. Note that FIG. 1 illustrates the electronic component 92 schematically.

[0072] (Second connection part) The second connection part 21 allows the adapter 3 to be attached and detached. More specifically, the second connection part 21 is configured to allow the adapter substrate 30 of the adapter 3 to be attached and detached. The adapter substrate 30 is attached to the second connection part 21 by inserting the adapter substrate 30. On the other hand, the second connection part 21 is detached from the adapter substrate 30 by removing the inserted adapter substrate 30. This configuration has the advantage that the adapter 3 can be easily replaced when the adapter substrate 30 of the adapter 3 deteriorates due to exposure to sample gas containing one or more types of molecules that flows into the internal space X1 of the housing 20 through the opening 26.

[0073] The second connection portion 21 is electrically connected to the electronic component 92 via a plurality of conductor portions 91. That is, the second connection portion 21 is electrically connected to each of the processing portion 23 and the control portion 24.

[0074] When the adapter substrate 30 is attached, the second connection portion 21 is electrically connected to the first connection portion 31 of the adapter 3 via the second connection terminal 33 and the plurality of conductor portions 32. Therefore, in an attached state in which the cartridge substrate 10 is attached to the first connection portion 31 and the adapter substrate 30 is attached to the second connection portion 21, the second connection portion 21 is electrically connected to each of the sensitive portion 11, the heater portion 12, and the temperature sensor 13. In addition, in the above-mentioned attached state, the second connection portion 21 electrically connects each of the heater portion 12 and the temperature sensor 13 to the control portion 24 (heater control portion 241). In other words, the second connection portion 21 is an interface that connects the adapter 3 and the device main body 2. FIG. 1 schematically illustrates the second connection portion 21.

[0075] (Control unit) As shown in FIG. 1, the control unit 24 includes a heater control unit 241 and a fan control unit 242.

[0076] The heater control unit 241 controls the power supplied to the heater unit 12 of the cartridge 1 based on the detection result of the temperature sensor 13. More specifically, the heater control unit 241 controls the power supplied to the heater unit 12 of the cartridge 1 based on the temperature of the sensitive unit 11 detected by the temperature sensor 13.

[0077] The heater control unit 241 controls the power supplied to the heater unit 12 to change the temperature of the sensor unit 11 between a first temperature, which is the ambient temperature, and a second temperature, which is higher than the ambient temperature. The second temperature is set, for example, to a temperature approximately 7°C to 35°C higher than the first temperature. The difference between the first and second temperatures is preferably a temperature difference that allows adsorption and desorption of odor molecules to occur and minimizes changes in resistance value caused by temperature changes. Here, the difference between the first and second temperatures should be at least 7°C or more and 35°C or less. The difference between the first and second temperatures is preferably 20°C or more and 35°C or less, and more preferably 20°C or more and 25°C or less.

[0078] For example, when the first temperature is 25°C, the heater control unit 241 controls the temperature of the sensory unit 11 between the first temperature of 25°C and the second temperature of 50°C. When the first temperature is 0°C, the temperature control unit 51 controls the temperature of the sensory unit 11 between the first temperature of 0°C and the second temperature of 25°C. When the first temperature is -20°C, the heater control unit 241 controls the temperature of the sensory unit 11 between the first temperature of -20°C and the second temperature of 5°C. The temperature change pattern in which the heater control unit 241 changes the temperature of the sensory unit 11 is not limited to the above-mentioned temperature change pattern, and the heater control unit 241 may change the temperature of the sensory unit 11 in a temperature change pattern that causes greater fluctuations in the change pattern of the output of the sensory unit 11 depending on the air quality of the sample gas.

[0079] The heater control unit 241 of the first embodiment controls the power supplied to the heater unit 12 based on the characteristic data stored in the memory unit 19 of the cartridge 1, i.e., the sensitivity characteristics of the electrical characteristic values ​​of the sensitive unit 11. More specifically, the heater control unit 241 of the first embodiment sets the second temperature based on the sensitivity characteristics of the electrical characteristic values ​​of the sensitive unit 11 so as to achieve a temperature difference that more reliably causes adsorption and desorption of odor molecules. The heater control unit 241 of the first embodiment controls the power supplied to the heater unit 12, thereby changing the temperature of the sensitive unit 11 between a first temperature, which is the ambient temperature, and a second temperature set based on the sensitivity characteristics of the electrical characteristic values ​​of the sensitive unit 11.

[0080] The fan control unit 242 controls the operation (rotation) of the fan 22 by controlling the power flowing to the fan 22. More specifically, the fan control unit 242 controls whether or not to rotate the fan 22, or the rotation amount of the fan 22. As an example, the fan control unit 242 has a function of detecting whether or not the cartridge 1 is inserted into the insertion port 27, and may control the fan 22 to rotate when it detects that the cartridge 1 has been inserted into the insertion port 27. On the other hand, the fan control unit 242 may control the fan 22 to stop when it detects that the cartridge 1 has been removed from the insertion port 27.

[0081] (Processing section) As shown in FIG. 1, the processing unit 23 includes an acquisition unit 231 and a calculation unit 232.

[0082] The acquisition unit 231 acquires data on the temperature change pattern of the sensitive unit 11 detected by the temperature sensor 13 and the pulse outputs of the sensitive elements A1-A16 for one cycle including one temperature rise period and one temperature fall period while the heater control unit 241 is passing a pulsed current through the heater unit 12. A constant DC voltage is applied to each of the sensitive elements A1-A16, and the acquisition unit 231 acquires changes in the electrical resistance of the sensitive elements A1-A16 as changes in the current flowing through the sensitive elements A1-A16. Therefore, the pulse outputs are current signals whose magnitudes change depending on the electrical resistance of the sensitive elements A1-A16. The acquisition unit 231 of the first embodiment acquires the pulse outputs of the sensitive elements A1-A16 for one cycle including one temperature rise period and one temperature fall period based on the characteristic data stored in the memory unit 19 of the cartridge 1, i.e., the sensitivity characteristics of the electrical characteristic values ​​of the sensitive unit 11.

[0083] When the acquisition unit 231 acquires data on the temperature change pattern of the sensitive part 11 and one cycle of pulse outputs from the sensitive elements A1 to A16, the calculation unit 232 calculates a pulse train in which the pulse outputs are connected in a predetermined order as a plurality of output data (i.e., change patterns of electrical characteristic values) of the sensitive part 11. Since the 16 sensitive elements A1 to A16 have different sensitivity characteristics to molecules to be detected, each of the plurality of output data becomes a pulse train with a different change pattern of electrical characteristic values.

[0084] (Communications Department) The communication unit 25 is a communication module capable of wired communication with a communication unit 45 (described later) of the evaluation device 4. That is, the communication unit 25 of the first embodiment communicates with the communication unit 45 of the evaluation device 4 via a cable CB1. The communication unit 25 transmits a plurality of pieces of output data calculated by the calculation unit 232 to the communication unit 45.

[0085] (1-2-5) Evaluation device 2, the evaluation device 4 includes a processing unit 41, a storage unit 42, a display unit 43, a power supply unit 44, and a communication unit 45. The evaluation device 4 is, for example, a laptop or desktop personal computer, a smartphone, or a tablet terminal. In the present disclosure, the description will be given assuming that the evaluation device 4 is a laptop personal computer.

[0086] The memory unit 42 includes one or more storage devices. The storage device is, for example, a RAM, a ROM, or an EEPROM. The memory unit 42 stores a trained model 421 and the like used to evaluate the air quality state of the sample gas. The trained model 421 is a trained model that learns the relationship between the change pattern of the output of the sensor unit 11 and the air quality state of the sample gas, using as training data the change pattern of the output of the sensor unit 11 when a first condition related to the gas to which the sensor unit 11 is exposed and a second condition related to the temperature change pattern for raising and lowering the temperature of the sensor unit 11 are changed. The trained model 421 may be generated by the air quality evaluation system 100, or may be generated by a learning system other than the air quality evaluation system 100.

[0087] The display unit 43 includes a display device such as a liquid crystal display. The display unit 43 displays the evaluation results input from the processing unit 41. For example, the display unit 43 displays the presence or absence of odor molecules in the sample gas, and if odor molecules are present, the amount of odor molecules, the quality of the odor, etc.

[0088] The processing unit 41 is a processing circuit that processes part of the operation of the air quality evaluation system 100. The processing unit 41 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs (applications) stored in one or more memories to function as the processing unit 41. Here, the programs are pre-recorded in the memory of the processing unit 41 or in the storage unit 42, but they may also be provided via a telecommunications line such as the Internet or by being recorded on a non-transitory recording medium such as a memory card.

[0089] As shown in FIG. 1, the processing unit 41 includes a learning unit 411 and an evaluation unit 412.

[0090] The learning unit 411 generates a trained model 421. That is, the learning unit 411 is responsible for the training phase. The learning unit 411 accumulates the temperature change pattern data acquired by the acquisition unit 231 and the output data of the sensor elements A1 to A16 as training data for generating the trained model 421. The learning unit 411 generates the trained model 421 using the collected training data. That is, the learning unit 411 causes an artificial intelligence program (algorithm) to learn the relationship between the change pattern (output data) of the electrical characteristic values ​​of the sensor elements A1 to A16 and the air quality state of the sample gas using the machine learning training data acquired by the air quality evaluation system 100. The artificial intelligence program is a machine learning model, and for example, a neural network, which is a type of hierarchical model, is used. The learning unit 411 generates the trained model 421 by having the neural network perform machine learning (e.g., deep learning) using the training data, and stores the trained model 421 in the storage unit 42. In addition, the learning unit 411 may improve the performance of the trained model 421 by performing re-learning using training data newly collected by the acquisition unit 231 after the trained model 421 is generated.

[0091] The evaluation unit 412 is responsible for the so-called inference phase. Using the trained model 421 stored in the storage unit 42, the evaluation unit 412 evaluates the state of the air quality of the sample gas based on the output data calculated by the calculation unit 232. Specifically, the evaluation unit 412 evaluates the state of the air quality of the sample gas by inputting the electrical characteristic values ​​of the sensor unit 11, which are measured while the heater control unit 241 controls the heater unit 12 so that the temperature of the sensor unit 11 exposed to the sample gas changes according to a temperature change pattern, into the trained model 421 generated by machine learning. Here, in the first embodiment, the sensor unit 11 includes multiple sensor elements Ax (sensor elements A1 to A16). Therefore, the evaluation unit 412 evaluates the state of the air quality of the sample gas based on the change pattern in the electrical characteristics of the multiple sensor elements Ax, which are measured while the temperature of the multiple sensor elements Ax exposed to the sample gas is changed according to the temperature change pattern. Furthermore, the evaluation unit 412 inputs the measurement data of the temperature change pattern obtained by the temperature sensor 13 and the output data calculated by the calculation unit 232 into the trained model 421. The trained model 421 performs inference based on the output data when the temperature of the sensor 11 changes according to the above-mentioned temperature change pattern, and evaluates the state of air quality of the sample gas. As described above, in the temperature range of -20°C or higher and 20°C or lower, the change in resistance value to odor molecules is greater in negative polarity sensor elements than in positive polarity sensor elements. Therefore, the evaluation unit 412 evaluates the state of air quality by placing emphasis on the output data of sensor elements A1 to A11. Furthermore, in the temperature range of 20°C or higher and 50°C or lower, the change in resistance value to odor molecules is greater in positive polarity sensor elements than in negative polarity sensor elements. Therefore, the evaluation unit 412 evaluates the state of air quality by placing emphasis on the output data of sensor elements A12 to A16.

[0092] In the first embodiment, the evaluation unit 412 evaluates the presence or absence of odor molecules in the sample gas as the air quality state of the sample gas, and evaluates whether the amount of odor molecules contained in the sample gas is equal to or greater than a threshold. If the evaluation unit 412 evaluates that the sample gas contains odor molecules, it may further evaluate the concentration of odor molecules in the sample gas.

[0093] It is not essential that the air quality evaluation system 100 includes the learning unit 411, and the evaluation unit 412 may perform the inference phase using a trained model 421 generated by an external computer system.

[0094] The evaluation unit 412 outputs the evaluation result to the display unit 43, thereby displaying the evaluation result of the evaluation unit 412 on the display unit 43. Note that the output of the evaluation result by the evaluation unit 412 is not limited to displaying it on the display unit 43, and the evaluation result, such as the presence or absence of odor molecules, may be output as sound using a buzzer or speaker.

[0095] The power supply unit 44 supplies power to the device main body 2 via the cable CB1. Furthermore, in an attached state in which the cartridge board 10 is attached to the first connection unit 31 and the adapter board 30 is attached to the second connection unit 21, the power supply unit 44 supplies power to the cartridge 1 via the device main body 2. If the evaluation device 4 includes a battery that stores power to drive the evaluation device 4, the power stored in the battery is supplied to the device main body 2 or the cartridge 1. Furthermore, if the power to drive the evaluation device 4 is supplied from an external power source, the evaluation device 4 may supply power supplied from the external power source to the device main body 2 or the cartridge 1.

[0096] The communication unit 45 is a communication module capable of wired communication with the communication unit 25 of the device body 2. That is, the communication unit 45 of the first embodiment communicates with the communication unit 25 of the device body 2 via the cable CB1. The communication unit 45 receives a plurality of output data transmitted by the communication unit 25 of the device body 2 and outputs the received output data to the processing unit 41.

[0097] (1-3) Effects In the main body system 200 according to the first embodiment, the housing 20 has a partition 28 that divides the internal space X1 into a first space X11 and a second space X12. The main body substrate 29 is accommodated in the second space X12. In an attached state in which the cartridge substrate 10 is attached to the main body system 200, the cartridge substrate 10 is attached to the first connection unit 31, and the acquisition unit 231 is electrically connected to the sensitive part 11 via the first connection unit 31, the adapter 3, and the second connection unit 21 to acquire an electrical characteristic value of the sensitive part 11. Furthermore, in the above-described attached state, at least a portion of the cartridge substrate 10 is accommodated in the first space X11, and one or more types of molecules (including a sample gas, described below) flow into the first space X11. This has the effect of preventing the main body substrate 29 from being deteriorated due to exposure to a sample gas containing one or more types of molecules. That is, the main body system 200 according to the first embodiment has the advantage of improving the durability of the main body substrate 29.

[0098] In the main body system 200 according to the first embodiment, the first connector 31 is located in the second space X12 of the housing 20. This provides the advantage that the first connector 31 is less likely to be exposed to one or more types of molecules because the second space X12 is a space into which sample gas containing one or more types of molecules is less likely to flow. This results in an advantage that the first connector 31 can be prevented from being deteriorated by one or more types of molecules.

[0099] In the main body system 200 according to the first embodiment, the second connection unit 21 is capable of detachably attaching the adapter 3. This has the advantage that the adapter 3 can be easily replaced when the adapter substrate 30 of the adapter 3 is deteriorated by one or more types of molecules.

[0100] In the main body system 200 according to the first embodiment, the adapter 3 has an adapter board 30, which is a printed wiring board provided with a second connection terminal 33, which is a wiring pattern, and a plurality of conductor portions 32. In the attached state, the adapter board 30 electrically connects the first connection portion 31 and the second connection portion 21 via the second connection terminal 33 and the plurality of conductor portions 32. This has the advantage of simplifying the configuration of the adapter 3.

[0101] (1-4) Modification of the first embodiment The above-described first embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. The following modified examples may be realized in appropriate combination. The same components as those in the above-described first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0102] (1-4-1) First Modification of the First Embodiment In the air quality evaluation system 100 of the above-described embodiment 1, the adapter 3 of the main system 200 has an adapter board 30, which is a printed wiring board on which a second connection terminal 33, which is a wiring pattern, and a plurality of conductor portions 32 are provided, and when the cartridge board 10 is attached to the first connection portion 31 and the adapter board 30 is attached to the second connection portion 21 described later, the adapter board 30 electrically connects the first connection portion 31 and the second connection portion 21 via the second connection terminal 33 and the plurality of conductor portions 32. However, in the air quality evaluation system 100A of the first variant of embodiment 1 shown in Figures 8 and 9, the adapter 3A of the main system 200A further has a cable 35 having a first end E1 at which the first connection portion 31 is provided and a second end E2 attached to the second connection portion 21A, and the cable 35 electrically connects the first connection portion 31 and the second connection portion 21A in an attached state in which the cartridge substrate 10 is attached to the first connection portion 31 and the second end E2 is attached to the second connection portion 21A.

[0103] The detailed configuration of the air quality evaluation system 100A according to the first modified example of the first embodiment will be described below.

[0104] The air quality evaluation system 100A of the first modified embodiment of embodiment 1 includes a cartridge 1, a main body system 200A, and an evaluation unit 412. The main body system 200A includes an adapter 3A and an apparatus main body 2A. Like the air quality evaluation system 100 of embodiment 1, the air quality evaluation system 100A of the first modified embodiment of embodiment 1 includes, in addition to the cartridge 1 and the main body system 200A, an evaluation device 4, which has the evaluation unit 412.

[0105] In the first variant of embodiment 1, as shown in FIG. 9, with the cartridge substrate 10 attached to the first connection portion 31 of the adapter 3A, the cartridge 1 is inserted into the insertion port 27 of the device main body 2A so that the first connection terminal 14 is positioned forward.

[0106] As shown in Figures 8 and 9, the adapter 3A of the first modified example includes an adapter board 30A, a first connection portion 31, a plurality of conductor portions 32, a second connection terminal 33, a connector 34, a cable 35, and a case 36.

[0107] 8, the cable 35 has a first end E1 and a second end E2. A first connection portion 31 is provided at the first end E1 of the cable 35, and the first end E1 of the cable 35 and the first connection portion 31 are electrically connected to each other. More specifically, an adapter board 30A having the first connection portion 31 and a plurality of conductor portions 32 is provided at the first end E1 of the cable 35, and the first end E1 of the cable 35 and the first connection portion 31 are electrically connected to each other via the plurality of conductor portions 32.

[0108] The adapter board 30A is a flat member. In the first modification, the adapter board 30A is a printed wiring board provided with a plurality of conductors 32, as shown in FIG. 7 . A first connection portion 31 is provided at the rear end of the first surface 301 of the adapter board 30A. The first end E1 of the cable 35 is electrically connected to the first connection portion 31 via the plurality of conductors 32. Each of the plurality of conductors 32 corresponds one-to-one to a plurality of electrodes in the first connection terminal 14 of the cartridge 1, and when the cartridge board 10 is attached to the first connection portion 31, the conductors 32 are electrically connected to the corresponding electrodes of the first connection terminal 14 via the first connection portion 31.

[0109] The second end E2 of the cable 35 is attached to the second connection portion 21A. More specifically, as shown in Fig. 8, a connector 34 is provided at the second end E2 of the cable 35, and the connector 34 is inserted into a socket 94 of the housing 20A, and the connector 34 is inserted into the second connection portion 21A of the device main body 2A, thereby attaching the second end E2 of the cable 35 to the second connection portion 21A. The socket 94 is provided on a side surface (front surface) of the housing 20A. The socket 94 is rectangular in side view.

[0110] A second connection terminal 33 is provided inside the connector 34 and is electrically connected to the first connection portion 31 via a cable 35. The second connection terminal 33 is electrically connected to the second connection portion 21A when the connector 34 is inserted into the second connection portion 21A of the device main body 2A and the second end E2 of the cable 35 is attached to the second connection portion 21A.

[0111] As described above, in an attached state in which the cartridge substrate 10 is attached to the first connecting portion 31 and the second end E2 of the cable 35 is attached to the second connecting portion 21A, the cable 35 electrically connects the first connecting portion 31 and the second connecting portion 21A. This configuration has the advantage of improving the degree of freedom in arranging the cartridge 1 relative to the second connecting portion 21A (i.e., the device main body 2A).

[0112] In the above-described attached state, the first connection portion 31 of the first modified example is located (exists) in a space (i.e., the first space X11) different from the second space X12 of the casing 20A, which will be described later. This configuration has the advantage of making it easier to attach and detach the cartridge substrate 10 to and from the first connection portion 31. Note that the "space different from the second space X12 of the casing 20A" referred to in the present disclosure may be, for example, the outside of the casing 20A, or a space different from the first space X11 and the second space X12 in the internal space X1 of the casing 20A.

[0113] 9, in the attached state, the cable 35 is located outside the housing 20A. With this configuration, the cable 35 of the adapter 3A (actually, a case 36, which will be described later and is provided at the second end E2 of the cable 35) is held, and the cartridge substrate 10 can be attached to and detached from the first connecting portion 31 of the adapter 3A. That is, there is an advantage in that the cartridge substrate 10 can be easily attached to and detached from the first connecting portion 31 of the adapter 3A.

[0114] As shown in FIG. 9, the case 36 houses the adapter board 30A. The case 36 is provided at the second end E2 of the cable 35. The case 36 is a hollow rectangular box with an opening at the rear. The first connection portion 31 is exposed from the opening of the case 36. The cable 35 is inserted through the front side of the case 36 and is electrically connected to the first connection portion 31 via multiple conductor portions 32. The case 36 is made of a resin material, for example.

[0115] The device main body 2A includes a housing 20A, a second connection unit 21A, a fan 22, a processing unit 23, a control unit 24, a communication unit 25, and a main body board 29. Note that a description of the same configurations of the housing 20A and the second connection unit 21A of the first modified example as those of the housing 20 and the second connection unit 21 of the first embodiment will be omitted.

[0116] The internal space X1 of the housing 20A has a first space X11 and a second space X12, and the housing 20A has a partition 28A that separates the first space X11 from the second space X12. The partition 28A of the first modification is a plate portion that protrudes inward (downward) from the inner surface (lower surface) of the top plate 201 of the housing 20A. Unlike the partition 28 of the first embodiment, the tip (lower end) of the partition 28A of the first modification is in contact with the bottom plate 202 of the housing 20A. That is, in the first modification, the first space X11 and the second space X12 are completely separated by the partition 28A. This configuration has the effect of further suppressing deterioration of the main body substrate 29 due to exposure to sample gas containing one or more types of molecules. That is, the main body system 200 of the first embodiment has the advantage of further improving the durability of the main body substrate 29.

[0117] The second connection portion 21A (see FIG. 8) is electrically connected to the electronic component 92 via a cable 93 (see FIG. 9) and a plurality of conductor portions 91. That is, the second connection portion 21A is electrically connected to each of the processing portion 23 and the control portion 24.

[0118] (1-4-2) Other Modifications of the First Embodiment Other variations of the above-described embodiment 1 are listed below. The following variations may be realized in appropriate combination.

[0119] In the above-described first embodiment, the partition 28 is provided between the opening 26 of the housing 20 and the first connection portion 31 of the adapter 3 in the front-rear direction in an attached state in which the cartridge substrate 10 is attached to the first connection portion 31 and the adapter substrate 30 is attached to the second connection portion 21. However, the partition 28 may be provided between the first connection portion 31 of the adapter 3 and the second connection portion 21 of the main body substrate 29 in the above-described attached state in the front-rear direction. In other words, the partition 28 may be provided at a position in the front-rear direction between the opening 26 of the housing 20 and the second connection portion 21 of the main body substrate 29.

[0120] In the first embodiment described above, the housing 20 has one partition 28, but may have multiple partitions 28. That is, the number of partitions 28 is not limited. As an example, the following description will be given assuming that the housing 20 has a first partition and a second partition as the partitions 28. In the above case, the housing 20 has a first space X11, a second space X12, and a third space that is a space different from the first space X11 and the second space X12. For example, the third space is a space located between the first space X11 and the second space X12 in the front-rear direction. The first partition divides the internal space X1 of the housing into the first space X11, the third space, and the second space X12, and the second partition divides the internal space X1 of the housing into the first space X11, the third space, and the second space X12. In short, the housing 20 may have a first space X11, a second space X12, and a space different from the first space X11 and the second space X12 (for example, the above-mentioned third space).

[0121] In the above-described first embodiment, the first connecting portion 31 is located in the second space X12 of the casing 20 in an attached state in which the cartridge substrate 10 is attached to the first connecting portion 31 and the second connecting terminal 33 is electrically connected to the second connecting portion 21 of the apparatus main body 2, but it may be located in a space different from the second space X12. For example, in the above-described attached state, the first connecting portion 31 may be located in the first space X11 of the casing 20 or may be located outside the casing 20. Furthermore, in the above-described attached state, the first connecting portion 31 may be located in a space different from the first space X11 and the second space X12 in the internal space X1 of the casing 20 (for example, the above-described third space).

[0122] In the first embodiment described above, in an attached state in which the cartridge substrate 10 is attached to the first connecting portion 31 and the second connecting terminal 33 is electrically connected to the second connecting portion 21 of the device main body 2, the direction in which the cartridge substrate 10 is attached to the first connecting portion 31 and the direction in which the adapter 3 is attached to the second connecting portion 21 are the same front-to-rear direction, as viewed from the thickness direction of the cartridge substrate 10. However, as in a main body system 200B of a second embodiment described later (see FIG. 10 ), in the above-described attached state, the first direction D1 in which the cartridge substrate 10 is attached to the first connecting portion 31 and the second direction D2 in which the adapter 3 is attached to the second connecting portion 21 may intersect (here, orthogonal) as viewed from the thickness direction of the cartridge substrate 10. This configuration makes it more difficult for sample gas containing one or more types of molecules to reach the main body substrate 29. This has the effect of further suppressing deterioration of the main body substrate 29 due to exposure to sample gas containing one or more types of molecules. In other words, there is an advantage in that the durability of the main body substrate 29 is further improved.

[0123] In the above-described first embodiment, the housing 20 accommodates a portion of the housing 17 of the cartridge 1 (more specifically, a portion excluding the front end portion of the housing 17) in an attached state in which the cartridge substrate 10 of the cartridge 1 is attached to the first connecting portion 31 and the adapter substrate 30 of the adapter 3 is attached to the second connecting portion 21. However, the housing 20 may accommodate the entire housing 17 of the cartridge 1 in the above-described attached state.

[0124] In the above-described first embodiment, the housing 20 houses the sensitive part 11 of the cartridge 1 in the mounted state. However, the housing 20 does not have to house the sensitive part 11 of the cartridge 1 in the mounted state. That is, the sensitive part 11 of the cartridge 1 may be disposed outside the housing 20 of the device main body 2 in the mounted state. In the above case, the device main body 2 does not need to have an opening 26 in the housing 20.

[0125] In the above-described first embodiment, the device body 2 has the fan 22, but it does not have to have the fan 22. In other words, the fan 22 is not an essential component.

[0126] In the above-described first embodiment, the processing unit 23 of the device main body 2 has the calculation unit 232, but the processing unit 41 of the evaluation device 4 may have the calculation unit 232. Similarly, in the above-described first embodiment, the processing unit 41 of the evaluation device 4 has the learning unit 411 and the evaluation unit 412, but the processing unit 23 of the device main body 2 may have at least one of the learning unit 411 and the evaluation unit 412.

[0127] In the above-described first embodiment, the device main body 2 and the evaluation device 4 are electrically connected via a cable CB1. However, the device main body 2 and the evaluation device 4 may be connected via wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). That is, the communication unit 25 of the device main body 2 in the first embodiment may be a communication module capable of wireless communication with the communication unit 45 of the evaluation device 4, and the communication unit 45 of the evaluation device 4 may be a communication module capable of wireless communication with the communication unit 25 of the device main body 2.

[0128] The device main body 2 and the evaluation device 4 may be connected via a network. That is, the communication unit 25 of the device main body 2 of the first embodiment may be a communication module capable of communicating with the communication unit 45 of the evaluation device 4 via a network, and the communication unit 45 of the evaluation device 4 may be a communication module capable of communicating with the communication unit 25 of the device main body 2 via a network.

[0129] The evaluation device 4 of the first embodiment described above includes a power supply unit 44 that supplies power to the device main body 2 via the cable CB1. However, the evaluation device 4 does not necessarily have to include the power supply unit 44, and the device main body 2 may have a battery that stores power to drive the device main body 2. Furthermore, the device main body 2 may receive power to drive the device main body 2 from an external power source.

[0130] (2) Embodiment 2 (2-1) Overview Hereinafter, a main body system 200B according to the second embodiment will be described with reference to Figures 10 and 11. The same components as those in the first embodiment will be denoted by the same reference numerals and will not be described again. Furthermore, each modification of the first embodiment may also be applied to the second embodiment as appropriate.

[0131] The main body system 200B of embodiment 2 differs from embodiment 1 in that, as shown in FIG. 10, in an installed state in which the cartridge substrate 10 is attached to the first connection portion 31 and the second connection terminal 33 is electrically connected to the second connection portion 21 of the device main body 2, when viewed from the thickness direction of the cartridge substrate 10, the first direction D1 in which the cartridge substrate 10 is attached to the first connection portion 31 and the second direction D2 in which the adapter 3 is attached to the second connection portion 21 intersect (here, are perpendicular).

[0132] (2-2) Detailed configuration (2-2-1) Air Quality Assessment System The detailed configuration of the air quality evaluation system 100B of the second embodiment will be described below.

[0133] The air quality evaluation system 100B of the second embodiment includes a cartridge 1, a main body system 200B, and an evaluation unit 412. The main body system 200B also includes an adapter 3B and an apparatus main body 2. Like the apparatus main body 2 of the first embodiment, the apparatus main body 2 of the second embodiment includes a housing 20, a second connection unit 21, a fan 22, a processing unit 23, a control unit 24, a communication unit 25, and a main body board 29. Like the air quality evaluation system 100 of the first embodiment, the air quality evaluation system 100B of the second embodiment also includes an evaluation device 4, which has the evaluation unit 412, in addition to the cartridge 1 and main body system 200B.

[0134] (2-2-2) Adapter As shown in FIGS. 10 and 11, the adapter 3B includes an adapter substrate 30B, a first connection portion 31, a plurality of conductor portions 32B, and a second connection terminal 33.

[0135] The adapter board 30B is a flat-plate-shaped member. The adapter board 30B is a printed wiring board provided with a second connection terminal 33, which is a wiring pattern, and a plurality of conductors 32B, and when the cartridge board 10 is attached to the main body system 200, the adapter board 30B electrically connects the first connection portion 31 and the second connection portion 21 via the second connection terminal 33 and the plurality of conductors 32B. The attached state here refers to a state in which the cartridge board 10 is attached to the first connection portion 31 and the adapter board 30B is attached to the second connection portion 21.

[0136] The second connection terminal 33 and the plurality of conductor portions 32B are a wiring pattern (for example, a copper foil pattern) provided on the first surface 301 of the adapter board 30B.

[0137] The second connection terminal 33 is electrically connected to the second connection portion 21 when the adapter board 30B is attached to the second connection portion 21 of the device body 2. As shown in Fig. 11, the second connection terminal 33 is provided on the right end portion of the first surface 101 of the adapter board 30B. The second connection terminal 33 has a plurality of electrodes aligned in the front-to-rear direction.

[0138] Each of the plurality of conductors 32B is electrically connected to at least one of the plurality of electrodes in the second connection terminal 33. Furthermore, each of the plurality of conductors 32B is electrically connected to the first connection portion 31. Each of the plurality of conductors 32B corresponds one-to-one to the plurality of electrodes in the first connection terminal 14 of the cartridge 1, and is electrically connected to the corresponding electrode of the first connection terminal 14 via the first connection portion 31 when the cartridge substrate 10 is attached to the first connection portion 31. In other words, when the cartridge substrate 10 is attached to the first connection portion 31, each of the plurality of electrodes in the first connection terminal 14 of the cartridge 1 is electrically connected to the corresponding electrode of the plurality of electrodes in the second connection terminal 33 of the adapter 3B via the first connection portion 31 and the corresponding conductor 32B.

[0139] In the second embodiment, as shown in Fig. 11, the first connection portion 31 is provided at the front end of the first surface 301 of the adapter board 30B, and the second connection terminal 33 is provided at the right end of the first surface 101 of the adapter board 30B. Therefore, in the main body system 200B of the second embodiment, when the cartridge board 10 is attached to the main body system 200, the first direction D1 (see Fig. 10) in which the cartridge board 10 is attached to the first connection portion 31 is the front-rear direction as viewed from the thickness direction of the cartridge board 10. On the other hand, when the cartridge board 10 is attached to the main body system 200B in the above-mentioned attached state, the second direction D2 (see Fig. 10) in which the adapter 3B is attached to the second connection portion 21 is the left-right direction as viewed from the thickness direction of the cartridge board 10. In short, in the main body system 200B of embodiment 2, in the above-mentioned mounted state, when viewed from the thickness direction of the cartridge substrate 10, the first direction D1 in which the cartridge substrate 10 is attached to the first connection portion 31 and the second direction D2 in which the adapter 3B is attached to the second connection portion 21 intersect (here, are perpendicular).

[0140] According to the above configuration, the sample gas containing one or more types of molecules is less likely to reach the main substrate 29. This has the effect of suppressing deterioration of the main substrate 29 due to exposure to the sample gas containing one or more types of molecules. That is, the main system 200B of the second embodiment has the advantage of improving the durability of the main substrate 29 on which the acquisition unit 231 that acquires the electrical characteristic value of the sensitive part 11 is provided.

[0141] (2-3) Modification of the second embodiment The above-described second embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Configurations similar to those of the above-described second embodiment are given the same reference numerals and descriptions thereof will be omitted. Furthermore, the above-described first and second embodiments may be realized in appropriate combination.

[0142] Below, we will list some variations of the above-described embodiment 2. The following variations may be realized in appropriate combination.

[0143] In the above-mentioned embodiment 2, the adapter 3B of the main body system 200B has an adapter board 30B which is a printed wiring board on which a second connection terminal 33 which is a wiring pattern and a plurality of conductor portions 32B are provided, and when the cartridge board 10 is attached to the first connection portion 31 and the adapter board 30B is attached to the second connection portion 21 described later, the adapter board 30B electrically connects the first connection portion 31 and the second connection portion 21 via the second connection terminal 33 and the plurality of conductor portions 32B. However, similar to the main body system 200A of the first variant of embodiment 1 described above (see Figures 8 and 9), the adapter 3B further has a cable 35 having a first end E1 at which the first connection portion 31 is provided and a second end E2 attached to the second connection portion 21A, and the cable 35 may electrically connect the first connection portion 31 and the second connection portion 21A in an attached state in which the cartridge substrate 10 is attached to the first connection portion 31 and the second end E2 is attached to the second connection portion 21A.

[0144] (summary) The main body system (200, 200A, 200B) of the first aspect is a main body system to which a cartridge substrate (10) having a sensitive part (11) whose electrical characteristic value changes in response to one or more types of molecules is attachable and detachable.

[0150] In the main body system (200A) of the fourth embodiment, in the first or second embodiment, the first connection part (31) is located in a space different from the second space (X12).

[0151] This embodiment has the advantage that the cartridge substrate (10) can be easily attached to and detached from the first connecting portion (31).
