　図３は、本発明の実施形態に係る電源ユニットの吸引側の断面図である。図２及び図３に示すように、接続部材４１３は、第一接続部材４１３１、第二接続部材４１２及び第三接続部材４１３３を含む。第一接続部材４１３１は、円筒状の部材であり、内側の側面に環状の段差４１３１Ｄが形成されている。第二接続部材４１３２は、環状の部材である。第三接続部材４１３３は、円筒状の部材である。 FIG. 3 is a cross-sectional view of the suction side of the power supply unit according to the embodiment of the present invention. As shown in FIGS. 2 and 3, the connecting member 413 includes a first connecting member 4131, a second connecting member 412, and a third connecting member 4133. The first connecting member 4131 is a cylindrical member, and an annular step 4131D is formed on the inner side surface. The second connecting member 4132 is an annular member. The third connecting member 4133 is a cylindrical member.
　図３に示すように、第一接続部材４１３１は、先端側の側面の外側が第二接続部材４１３２及び第三接続部材４１３３に覆われる。すなわち、第一接続部材４１３１は、先端側が第二接続部材４１３２及び第三接続部材４１３３に挿入される。第二接続部材４１３２は、吸引側の縁が第一接続部材４１３１に接触し、先端側の縁が第三接続部材４１３３に接触している。第三接続部材４１３３は、先端側の側面の外側がケース４０１に覆われる。すなわち、第三接続部材４１３３は、ケース４０１に挿入される。 As shown in FIG. 3, the outer side surface of the first connecting member 4131 is covered with the second connecting member 4132 and the third connecting member 4133. That is, the tip end side of the first connecting member 4131 is inserted into the second connecting member 4132 and the third connecting member 4133. In the second connecting member 4132, the suction side edge is in contact with the first connecting member 4131, and the tip end side edge is in contact with the third connecting member 4133. The outside of the side surface of the third connecting member 4133 on the distal end side is covered with the case 401. That is, the third connecting member 4133 is inserted into the case 401.
　基板ホルダ４１４は、吸引側に底面を備える円筒状の部材であり、外側の側面に環状の段差４１４Ｄが形成されている。この底面には、孔４１４Ｈが設けられている。孔４１４Ｈは、カートリッジケース２に設けられている孔２Ｈから導入された空気を基板ホルダ４１４よりも先端側に導入するための孔である。また、基板ホルダ４１４は、第一接続部材４１３１に収納される。 The substrate holder 414 is a cylindrical member having a bottom surface on the suction side, and an annular step 414D is formed on the outer side surface. A hole 414H is provided on the bottom surface. The hole 414H is a hole for introducing the air introduced from the hole 2H provided in the cartridge case 2 to the tip side of the substrate holder 414. Further, the substrate holder 414 is housed in the first connecting member 4131.
　オーリング４１５は、弾性体、例えば、シリコンゴムで作製された環状の部材である。オーリング４１５は、第一接続部材４１３１に形成されている段差４１３１Ｄと基板ホルダ４１４に形成されている段差４１４Ｄとに挟まれる。これにより、オーリング４１５は、カートリッジケース２内に存在する流体が第一接続部材４１３１と基板ホルダ４１４との隙間からケース４０１の内部に侵入しないようにする。 The O-ring 415 is an elastic body, for example, an annular member made of silicon rubber. The O-ring 415 is sandwiched between the step 4131D formed on the first connecting member 4131 and the step 414D formed on the substrate holder 414. As a result, the O-ring 415 prevents the fluid existing in the cartridge case 2 from entering the inside of the case 401 through the gap between the first connecting member 4131 and the substrate holder 414.
　第二回路基板４１６は、気圧センサ４１６Ｐ、端子４１６１及び端子４１６２が実装されている円形の回路基板である。気圧センサ４１６Ｐ、端子４１６１及び端子４１６２は、いずれも吸引側に実装されている。また、第二回路基板４１６は、気圧センサ４１６Ｐ、端子４１６１及び端子４１６２が実装されていない面の縁がホルダ４０２の吸引側の縁及び透光部材４１０の吸引側の縁と接触している。 The second circuit board 416 is a circular circuit board on which the barometric pressure sensor 416P, the terminal 4161 and the terminal 4162 are mounted. The barometric pressure sensor 416P, terminal 4161 and terminal 4162 are all mounted on the suction side. Further, in the second circuit board 416, the edge of the surface on which the barometric pressure sensor 416P, the terminal 4161 and the terminal 4162 are not mounted is in contact with the edge on the suction side of the holder 402 and the edge on the suction side of the translucent member 410.
　気圧センサ４１６Ｐは、例えば、静電容量型の圧力センサ、ピエゾ抵抗方式の圧力センサであり、所定の時間における気圧を計測した結果を示す気圧データを生成する。ここで言う所定の時間は、例えば、非燃焼式吸引器１の電源がオンとなった時点からオフとなる時点までの６０ｍｓｅｃ（ミリ秒）ごとのタイミングである。ただし、ここで言う所定の時間は、周期的なタイミングではなく、非周期的なタイミングであってもよい。また、所定の時間は、一定の長さを有する期間であってもよいし、任意の時刻であってもよい。なお、気圧センサ４１６Ｐは、絶対圧を測定してもよいし、ゲージ圧を測定してもよい。また、気圧データは、後述する取得部４１に送信されてもよいし、非燃焼式吸引器１又は上述した他の機器に設けられている記憶媒体に格納されてもよい。 The barometric pressure sensor 416P is, for example, a capacitance type pressure sensor or a piezo resistance type pressure sensor, and generates barometric pressure data showing the result of measuring the barometric pressure at a predetermined time. The predetermined time referred to here is, for example, a timing every 60 msec (milliseconds) from the time when the power of the non-combustion type suction device 1 is turned on to the time when the power is turned off. However, the predetermined time referred to here may be an aperiodic timing instead of a periodic timing. Further, the predetermined time may be a period having a certain length or an arbitrary time. The barometric pressure sensor 416P may measure the absolute pressure or the gauge pressure. Further, the atmospheric pressure data may be transmitted to the acquisition unit 41 described later, or may be stored in the storage medium provided in the non-combustion suction device 1 or the other device described above.
　端子４１６１は、電池４０３の正極と電気的に接続されており、基板ホルダ４１４の底面を貫通して吸引側へ突出している。また、端子４１６２は、電池４０３の負極と電気的に接続されており、基板ホルダ４１４の底面を貫通して吸引側へ突出している。 The terminal 4161 is electrically connected to the positive electrode of the battery 403, penetrates the bottom surface of the substrate holder 414, and projects to the suction side. Further, the terminal 4162 is electrically connected to the negative electrode of the battery 403, penetrates the bottom surface of the substrate holder 414, and projects to the suction side.
　パッキン４１７は、弾性体、例えば、シリコンゴムで作製された環状の部材である。パッキン４１７は、基板ホルダ４１４の先端側の縁と第二回路基板４１６のうち気圧センサ４１６Ｐ、端子４１６１及び端子４１６２が実装されている面の縁とに挟まれる。これにより、パッキン４１７は、基板ホルダ４１４に設けられた孔４１４Ｈから基板ホルダ４１４１の底面よりも先端側に進入した流体が基板ホルダ４１４と第二回路基板４１６との隙間から第二回路基板４１６よりも先端側に侵入しないようにする。 The packing 417 is an elastic body, for example, an annular member made of silicon rubber. The packing 417 is sandwiched between the edge on the tip end side of the substrate holder 414 and the edge of the surface of the second circuit board 416 on which the barometric pressure sensor 416P, the terminal 4161 and the terminal 4162 are mounted. As a result, in the packing 417, the fluid that has entered from the hole 414H provided in the substrate holder 414 to the tip side of the bottom surface of the substrate holder 4141 is transmitted from the second circuit board 416 through the gap between the substrate holder 414 and the second circuit board 416. Do not invade the tip side.
　ＦＰＣ４１８は、第一回路基板４１１に実装されている電子部品と第二回路基板４１６に実装されている電子部品とを電気的に接続している。 The FPC 418 electrically connects the electronic component mounted on the first circuit board 411 and the electronic component mounted on the second circuit board 416.
　次に、図４及び図５を参照しながら、実施形態に係る電源ユニットの機能について説明する。図４は、本発明の実施形態に係る電源ユニットの機能的な構成の一例を示す図である。図４に示すように、電源ユニット４は、取得部４１と、判定部４２と、更新部４３と、再設定部４４と、制御部４５とを備える。 Next, the function of the power supply unit according to the embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing an example of a functional configuration of the power supply unit according to the embodiment of the present invention. As shown in FIG. 4, the power supply unit 4 includes an acquisition unit 41, a determination unit 42, an update unit 43, a reset unit 44, and a control unit 45.
　取得部４１は、所定の時間における気圧を示す気圧データを順次取得する。具体的には、取得部４１は、上述した気圧センサ４１６Ｐが６０ｍｓｅｃごとに計測した気圧データを逐一取得する。取得部４１は、気圧データを気圧センサ４１６Ｐから直接取得してもよいし、非燃焼式吸引器１又は上述した他の機器に設けられている記憶媒体から取得してもよい。 The acquisition unit 41 sequentially acquires atmospheric pressure data indicating the atmospheric pressure at a predetermined time. Specifically, the acquisition unit 41 acquires the atmospheric pressure data measured by the atmospheric pressure sensor 416P described above every 60 msec one by one. The acquisition unit 41 may acquire the atmospheric pressure data directly from the atmospheric pressure sensor 416P, or may acquire the atmospheric pressure data from the non-combustion suction device 1 or the storage medium provided in the other device described above.
　判定部４２は、取得部４１により取得された気圧データが示す気圧と基準気圧との差が基準気圧更新用閾値以下であるか否かを判定する。 The determination unit 42 determines whether or not the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 and the reference atmospheric pressure is equal to or less than the reference atmospheric pressure update threshold value.
　ここで、基準気圧は、判定部４２が実行する各判定で使用される気圧であり、所定の数の気圧データ各々が示す気圧の移動平均である。例えば、基準気圧は、直近の２０個の気圧データ各々が示す気圧の移動平均である。これにより、基準気圧は、非燃焼式吸引器１の周囲の気圧に追従する気圧となっている。ただし、基準気圧は、必ずしも直近の所定の数の気圧データ各々が示す気圧の移動平均でなくてもよく、連続して取得された気圧データ各々が示す気圧の移動平均でなくてもよい。 Here, the reference atmospheric pressure is the atmospheric pressure used in each determination executed by the determination unit 42, and is a moving average of the atmospheric pressure indicated by each of a predetermined number of atmospheric pressure data. For example, the reference pressure is a moving average of the pressure shown by each of the latest 20 pressure data. As a result, the reference pressure is a pressure that follows the pressure around the non-combustion type suction device 1. However, the reference pressure does not necessarily have to be the moving average of the atmospheric pressure indicated by each of the latest predetermined number of atmospheric pressure data, and does not have to be the moving average of the atmospheric pressure indicated by each of the continuously acquired atmospheric pressure data.
　基準気圧更新用閾値は、基準気圧を更新するか否かの判定に使用される閾値である。基準気圧更新用閾値は、後述する吸引検知用閾値よりも小さい気圧、例えば、１００Ｐａ（パスカル）である。なぜなら、基準気圧更新用閾値は、カートリッジケース２内のエアロゾルが吸引されている場合における気圧が上述した移動平均に組み込まれて基準気圧が低下し、基準気圧が非燃焼式吸引器１の周囲の気圧から乖離してしまうことを避けるために使用される閾値だからである。ただし、基準気圧更新用閾値は、瞬間的に発生するノイズが上述した移動平均に組み込まれてしまうことを避けるために、ある程度の大きさを有している必要がある。 The reference pressure update threshold is a threshold used to determine whether or not to update the reference pressure. The reference pressure update threshold value is a pressure smaller than the suction detection threshold value described later, for example, 100 Pa (Pascal). This is because the reference pressure update threshold is such that the pressure when the aerosol in the cartridge case 2 is sucked is incorporated into the above-mentioned moving average to lower the reference pressure, and the reference pressure is around the non-combustible suction device 1. This is because it is a threshold used to avoid deviation from atmospheric pressure. However, the threshold value for updating the reference atmospheric pressure needs to have a certain magnitude in order to prevent the momentarily generated noise from being incorporated into the above-mentioned moving average.
　また、判定部４２は、取得部４１により取得された気圧データが示す気圧と基準気圧との差が吸引検知用閾値を超えている吸引状態にあるか否かを判定する。 Further, the determination unit 42 determines whether or not the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 and the reference atmospheric pressure is in the suction state exceeding the suction detection threshold value.
　ここで、吸引検知用閾値は、非燃焼式吸引器１が吸引状態にあるか否かの判定に使用される閾値である。また、吸引検知用閾値は、基準気圧更新用閾値及び後述する第一基準気圧判定用閾値よりも大きい気圧であり、例えば、－１２０Ｐａである。吸引状態は、カートリッジケース２内のエアロゾルが吸引されることにより、気圧センサ４１６Ｐにより計測される気圧と基準気圧との差が吸引検知用閾値を超えている状態である。 Here, the suction detection threshold value is a threshold value used for determining whether or not the non-combustion suction device 1 is in the suction state. Further, the suction detection threshold value is an atmospheric pressure larger than the reference pressure update threshold value and the first reference pressure determination threshold value described later, and is, for example, −120 Pa. The suction state is a state in which the difference between the atmospheric pressure measured by the atmospheric pressure sensor 416P and the reference atmospheric pressure exceeds the suction detection threshold value due to the suction of the aerosol in the cartridge case 2.
　また、判定部４２は、気圧データが示す気圧と基準気圧との差が第一基準気圧判定用閾値を超えている基準気圧低下状態が基準気圧判定用時間を超えて継続しているか否かを判定する。 Further, the determination unit 42 determines whether or not the reference pressure drop state in which the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference pressure exceeds the first reference pressure determination threshold exceeds the reference pressure determination time. judge.
　第一基準気圧判定用閾値は、弱い吸引が継続した際に、気圧データが示す気圧と基準気圧との差が大きくなることにより、カートリッジケース２内のエアロゾルが吸引されたにも関わらず、吸引を検知できない誤判定を避けるために使用される閾値である。また、第一基準気圧判定用閾値は、吸引検知用閾値よりも小さい気圧、例えば、＋１００Ｐａである。なぜなら、第一基準気圧判定用閾値は、弱い吸引が行われている場合における気圧が上述した移動平均に組み込まれて基準気圧が低下し、基準気圧が非燃焼式吸引器１の周囲の気圧から乖離してしまうことを避けるために使用される閾値だからである。また、ここで言う弱い吸引は、例えば、基準気圧が大気圧と略等しい場合に、気圧データが示す気圧と基準気圧との差が吸引検知用閾値以下となるような吸引である。基準気圧判定用時間は、当該誤判定を避けるために使用される時間であり、例えば、０．１秒から０．６秒である。 The first reference pressure determination threshold is suction even though the aerosol in the cartridge case 2 is sucked because the difference between the pressure indicated by the atmospheric pressure data and the reference pressure becomes large when weak suction continues. This is the threshold used to avoid false positives that cannot be detected. Further, the threshold value for determining the first reference atmospheric pressure is an atmospheric pressure smaller than the threshold value for suction detection, for example, +100 Pa. This is because the first reference pressure determination threshold is such that the pressure when weak suction is performed is incorporated into the above-mentioned moving average to lower the reference pressure, and the reference pressure is derived from the pressure around the non-combustible suction device 1. This is because the threshold is used to avoid divergence. Further, the weak suction referred to here is, for example, a suction in which the difference between the pressure indicated by the atmospheric pressure data and the reference pressure is equal to or less than the suction detection threshold when the reference pressure is substantially equal to the atmospheric pressure. The reference atmospheric pressure determination time is a time used to avoid the erroneous determination, and is, for example, 0.1 seconds to 0.6 seconds.
　また、判定部４２は、更新部４３により基準気圧が更新された後、更新後の基準気圧と更新前の基準気圧との差が第二基準気圧判定用閾値を超えているか否かを判定する。第二基準気圧判定用閾値は、気圧データが示す気圧と基準気圧との差が大きくなることにより、カートリッジケース２内のエアロゾルが吸引されたにも関わらず、吸引を検知できない誤判定を避けるために使用される閾値である。また、第二基準気圧判定用閾値は、任意の値の気圧でよい。例えば、判定部４２は、５秒前の基準気圧と現在の基準気圧との差が４０Ｐａを超えているか否かを判定する。 Further, the determination unit 42 determines whether or not the difference between the updated reference pressure and the reference pressure before the update exceeds the second reference pressure determination threshold value after the reference pressure is updated by the update unit 43. .. The second reference atmospheric pressure determination threshold is for avoiding an erroneous determination in which suction cannot be detected even though the aerosol in the cartridge case 2 is sucked due to a large difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure. The threshold used for. Further, the threshold value for determining the second reference atmospheric pressure may be an atmospheric pressure of an arbitrary value. For example, the determination unit 42 determines whether or not the difference between the reference pressure 5 seconds ago and the current reference pressure exceeds 40 Pa.
　また、判定部４２は、気圧データが示す気圧と基準気圧との差が気圧センサ故障判定用閾値を超えている気圧センサ故障状態が気圧センサ故障判定用時間を超えて継続しているか否かを判定する。 Further, the determination unit 42 determines whether or not the atmospheric pressure sensor failure state in which the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure exceeds the atmospheric pressure sensor failure determination threshold exceeds the atmospheric pressure sensor failure determination time. judge.
　気圧センサ故障判定用閾値は、上述した気圧センサ４１６Ｐが故障しているか否かを判定するために使用される閾値である。気圧センサ故障判定用閾値は、任意の値の気圧であり、例えば、１００Ｐａである。気圧センサ故障判定用時間は、当該判定に使用される時間であり、例えば、１０秒である。 The barometric pressure sensor failure determination threshold value is a threshold value used for determining whether or not the barometric pressure sensor 416P described above has failed. The barometric pressure sensor failure determination threshold value is an atmospheric pressure of an arbitrary value, for example, 100 Pa. The barometric pressure sensor failure determination time is the time used for the determination, for example, 10 seconds.
　なお、上記の説明では、基準気圧更新用閾値が１００Ｐａであり、第一基準気圧判定用閾値が＋１００Ｐａであり、気圧センサ故障判定用閾値が１００Ｐａである場合を例に挙げて説明したが、これに限定されない。例えば、第一基準気圧判定用閾値及び気圧センサ故障判定用閾値は、基準気圧更新用閾値よりも絶対値が小さな気圧であってもよい。 In the above description, the case where the reference pressure update threshold value is 100 Pa, the first reference pressure determination threshold value is +100 Pa, and the pressure sensor failure determination threshold value is 100 Pa has been described as an example. Not limited to. For example, the first reference atmospheric pressure determination threshold and the atmospheric pressure sensor failure determination threshold may be atmospheric pressures whose absolute values are smaller than the reference atmospheric pressure update threshold.
　また、判定部４２は、例えば、気圧センサ４１６Ｐが気圧を計測して気圧データを生成し、取得部４１が当該気圧データを取得する度に上述した全ての判定を一回ずつ実行する。だだし、判定部４２が上述した判定を実行するタイミング及び回数は、特に限定されない。 Further, the determination unit 42, for example, measures the atmospheric pressure by the atmospheric pressure sensor 416P and generates atmospheric pressure data, and every time the acquisition unit 41 acquires the atmospheric pressure data, all the above-mentioned determinations are executed once. However, the timing and the number of times that the determination unit 42 executes the above-mentioned determination is not particularly limited.
　更新部４３は、所定の時間に基準気圧を更新する。例えば、更新部４３は、取得部４１により取得された気圧データが示す気圧と前記基準気圧との差が基準気圧更新用閾値以下であると判定される度に最新の気圧データが示す気圧を含めた移動平均を計算することにより基準気圧を更新する。ただし、更新部４３は、最新の気圧データではなく、最新の気圧データよりも前に取得部４１により取得された気圧データが示す気圧を含めた移動平均を計算することにより基準気圧を更新してもよい。 The update unit 43 updates the reference atmospheric pressure at a predetermined time. For example, the update unit 43 includes the atmospheric pressure indicated by the latest atmospheric pressure data each time it is determined that the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 and the reference atmospheric pressure is equal to or less than the reference atmospheric pressure update threshold. The reference pressure is updated by calculating the moving average. However, the update unit 43 updates the reference atmospheric pressure by calculating the moving average including the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 before the latest atmospheric pressure data, instead of the latest atmospheric pressure data. May be good.
　再設定部４４は、気圧データが示す気圧と基準気圧との差が第一基準気圧判定用閾値を超えている基準気圧低下状態が基準気圧判定用時間を超えて継続していると判定された場合、基準気圧を設定し直す。例えば、再設定部４４は、このように判定される度に、現在の基準気圧を非燃焼式吸引器１の電源がオンになった直後に計算された基準気圧で上書きする。 The resetting unit 44 has determined that the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure exceeds the first reference atmospheric pressure determination threshold, and the reference atmospheric pressure lowering state continues beyond the reference atmospheric pressure determination time. If so, reset the reference pressure. For example, the resetting unit 44 overwrites the current reference pressure with the reference pressure calculated immediately after the power of the non-combustion suction device 1 is turned on each time the determination is made in this way.
　また、再設定部４４は、更新後の基準気圧と更新前の基準気圧との差が第二基準気圧判定用閾値を超えていると判定された場合、基準気圧を設定し直す。例えば、再設定部４４は、このように判定される度に、現在の基準気圧を非燃焼式吸引器１の電源がオンになった直後に計算された基準気圧で上書きする。或いは、再設定部４４は、このように判定される度に、６０ｍｓｅｃごとに計測された気圧を示す気圧データが所定の数以上生成されるまで待機し、気圧データが所定の数以上生成された後、これらの気圧データ各々が示す気圧の移動平均を新しい基準気圧とする。 Further, the resetting unit 44 resets the reference pressure when it is determined that the difference between the reference pressure after the update and the reference pressure before the update exceeds the threshold for determining the second reference pressure. For example, the resetting unit 44 overwrites the current reference pressure with the reference pressure calculated immediately after the power of the non-combustion suction device 1 is turned on each time the determination is made in this way. Alternatively, each time the resetting unit 44 is determined in this way, it waits until a predetermined number or more of atmospheric pressure data indicating the atmospheric pressure measured every 60 msec is generated, and the atmospheric pressure data is generated in a predetermined number or more. Later, the moving average of the atmospheric pressure indicated by each of these atmospheric pressure data will be used as the new reference atmospheric pressure.
　制御部４５は、取得部４１により取得された気圧データが示す気圧と基準気圧との差が吸引検知用閾値を超えている吸引状態にあると判定される度に、上述したヒータを作動させる。 The control unit 45 operates the above-mentioned heater each time it is determined that the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 and the reference atmospheric pressure is in the suction state exceeding the suction detection threshold value.
　また、制御部４５は、気圧データが示す気圧と基準気圧との差が気圧センサ故障判定用閾値を超えている気圧センサ故障状態が気圧センサ故障判定用時間を超えて継続していると判定された場合、電源ユニット４を停止させる。すなわち、制御部４５は、このように判定された場合、非燃焼式吸引器１の電源をオフにする。 Further, the control unit 45 determines that the atmospheric pressure sensor failure state in which the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure exceeds the atmospheric pressure sensor failure determination threshold exceeds the atmospheric pressure sensor failure determination time. If so, the power supply unit 4 is stopped. That is, the control unit 45 turns off the power of the non-combustion type suction device 1 when it is determined in this way.
　なお、制御部４５は、上述した制御に加え、非燃焼式吸引器１の各部に関する制御を適宜実行する。 In addition to the above-mentioned control, the control unit 45 appropriately executes control related to each part of the non-combustion type suction device 1.
　次に、図５を参照しながら、実施形態に係る電源ユニットの動作の一例を説明する。図５は、本発明の実施形態に係る電源ユニットの動作を説明するための図である。図５に示した点線Ｃは、気圧センサ４１６Ｐにより計測された気圧を表している。図５に示した実線Ｓは、更新部４３により更新された基準気圧を表している。また、図５は、四つの期間、すなわち期間Ｔ１、期間Ｔ２、期間Ｔ３及び期間Ｔ４を含んでいる。なお、電源ユニット４は、期間Ｔ１、期間Ｔ２、期間Ｔ３及び期間Ｔ４において、６０ｍｓｅｃごとに上述した取得部４１、判定部４２、更新部４３、再設定部４４及び制御部４５各々が実行する処理を実行するものとする。 Next, an example of the operation of the power supply unit according to the embodiment will be described with reference to FIG. FIG. 5 is a diagram for explaining the operation of the power supply unit according to the embodiment of the present invention. The dotted line C shown in FIG. 5 represents the atmospheric pressure measured by the atmospheric pressure sensor 416P. The solid line S shown in FIG. 5 represents the reference atmospheric pressure updated by the updating unit 43. FIG. 5 also includes four periods, namely period T1, period T2, period T3 and period T4. The power supply unit 4 is a process executed by each of the acquisition unit 41, the determination unit 42, the update unit 43, the reset unit 44, and the control unit 45 described above every 60 msec in the period T1, the period T2, the period T3, and the period T4. Shall be executed.
　期間Ｔ１は、上述した弱い吸引ではなく、通常の吸引が行われる期間である。期間Ｔ１では、気圧データが示す気圧は、吸引が行われていない場合、大気圧ＡＰと略等しくなり、吸引が行われている場合、大気圧ＡＰよりも低くなる。また、期間Ｔ１では、吸引が行われている場合における気圧が上述した移動平均に組み込まれないため、基準気圧は、略一定となる。なお、ここで言う通常の吸引とは、基準気圧が大気圧と略等しい場合に、気圧データが示す気圧と基準気圧との差が吸引検知用閾値を超えるような吸引である。 Period T1 is a period during which normal suction is performed instead of the weak suction described above. In the period T1, the atmospheric pressure indicated by the atmospheric pressure data is substantially equal to the atmospheric pressure AP when suction is not performed, and is lower than the atmospheric pressure AP when suction is performed. Further, in the period T1, the reference atmospheric pressure becomes substantially constant because the atmospheric pressure when suction is performed is not incorporated into the above-mentioned moving average. The normal suction referred to here is suction in which the difference between the pressure indicated by the atmospheric pressure data and the reference pressure exceeds the suction detection threshold when the reference pressure is substantially equal to the atmospheric pressure.
　期間Ｔ２は、上述した弱い吸引が行われる期間である。期間Ｔ２でも、期間Ｔ１と同様に、気圧データが示す気圧は、吸引が行われていない場合、大気圧ＡＰと略等しくなり、吸引が行われている場合、大気圧ＡＰよりも低くなる。ただし、期間Ｔ２では、期間Ｔ１と異なり、吸引が行われている場合における気圧が上述した移動平均に組み込まれるため、基準気圧は、徐々に低下する。 Period T2 is the period during which the above-mentioned weak suction is performed. In the period T2 as well, as in the period T1, the atmospheric pressure indicated by the atmospheric pressure data is substantially equal to the atmospheric pressure AP when suction is not performed, and is lower than the atmospheric pressure AP when suction is performed. However, in the period T2, unlike the period T1, the air pressure when suction is performed is incorporated into the above-mentioned moving average, so that the reference air pressure gradually decreases.
　期間Ｔ３は、再設定部４４により基準気圧が更新されている期間である。したがって、基準気圧は、期間Ｔ３の間、不確定である。 Period T3 is the period during which the reference atmospheric pressure is updated by the resetting unit 44. Therefore, the reference pressure is uncertain during period T3.
　期間Ｔ４は、再設定部４４により基準気圧が更新され、上述した弱い吸引ではなく、通常の吸引が行われる期間である。期間Ｔ４では、期間Ｔ１と同様に、気圧データが示す気圧は、吸引が行われていない場合、大気圧ＡＰと略等しくなり、吸引が行われている場合、大気圧ＡＰよりも低くなる。また、期間Ｔ４では、期間Ｔ１と同様に、吸引が行われている場合における気圧が上述した移動平均に組み込まれないため、基準気圧は、略一定となる。 The period T4 is a period in which the reference air pressure is updated by the resetting unit 44 and normal suction is performed instead of the weak suction described above. In the period T4, as in the period T1, the atmospheric pressure indicated by the atmospheric pressure data is substantially equal to the atmospheric pressure AP when suction is not performed, and is lower than the atmospheric pressure AP when suction is performed. Further, in the period T4, as in the period T1, the air pressure when suction is performed is not incorporated into the above-mentioned moving average, so that the reference air pressure becomes substantially constant.

　以上、実施形態に係る非燃焼式吸引器１について電源ユニット４を中心に説明した。 The non-combustion type suction device 1 according to the embodiment has been described above, focusing on the power supply unit 4.
　電源ユニット４は、所定の時間における気圧を示す気圧データを順次取得する取得部４１と、気圧データが示す気圧と基準気圧との差が第一基準気圧判定用閾値を超えている基準気圧低下状態が基準気圧判定用時間を超えて継続しているか否かを判定する判定部４２と、基準気圧低下状態が基準気圧判定用時間を超えて継続していると判定された場合、基準気圧を設定し直す再設定部４４とを備える。 The power supply unit 4 has a reference pressure drop state in which the difference between the acquisition unit 41 that sequentially acquires the atmospheric pressure data indicating the atmospheric pressure at a predetermined time and the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure exceeds the first reference atmospheric pressure determination threshold. The determination unit 42, which determines whether or not the vehicle continues beyond the reference pressure determination time, and the reference pressure setting when it is determined that the reference pressure decrease state continues beyond the reference pressure determination time. It is provided with a resetting unit 44 for resetting.
　これにより、電源ユニット４は、弱い吸引が行われている場合における気圧が移動平均に組み込まれて基準気圧が低下してしまっても適切な基準気圧に戻す。したがって、電源ユニット４は、弱い吸引が継続した際に通常の吸引を検知できない誤判定を避け、吸引を正確に判定することができる。 As a result, the power supply unit 4 returns to an appropriate reference pressure even if the pressure in the case of weak suction is incorporated into the moving average and the reference pressure drops. Therefore, the power supply unit 4 can avoid erroneous determination that normal suction cannot be detected when weak suction continues, and can accurately determine suction.
　電源ユニット４は、所定の時間に基準気圧を更新する更新部４３を更に備え、判定部４２により更新後の基準気圧と更新前の基準気圧との差が第二基準気圧判定用閾値を超えているか否かを更に判定し、再設定部４４により更新後の基準気圧と更新前の基準気圧との差が第二基準気圧判定用閾値を超えていると更に判定された場合、基準気圧を設定し直す。 The power supply unit 4 further includes an update unit 43 that updates the reference pressure at a predetermined time, and the difference between the reference pressure after the update and the reference pressure before the update exceeds the second reference pressure determination threshold by the determination unit 42. If it is further determined by the resetting unit 44 that the difference between the updated reference pressure and the pre-update reference pressure exceeds the second reference pressure determination threshold, the reference pressure is set. Redo.
　これにより、電源ユニット４は、弱い吸引が行われている場合における気圧が移動平均に組み込まれて基準気圧が低下してしまっても適切な基準気圧に戻す。したがって、電源ユニット４は、弱い吸引が継続した際に通常の吸引を検知できない誤判定を避け、吸引を正確に判定することができる。 As a result, the power supply unit 4 returns to an appropriate reference pressure even if the pressure in the case of weak suction is incorporated into the moving average and the reference pressure drops. Therefore, the power supply unit 4 can avoid erroneous determination that normal suction cannot be detected when weak suction continues, and can accurately determine suction.
　また、電源ユニット４は、第一基準気圧判定用閾値を使用した判定及び第二基準気圧判定用閾値を使用した判定を併用することにより、基準気圧が低下してしまっていることを更に精度良く検知し、適切な基準気圧に戻すことができる。 Further, the power supply unit 4 further accurately confirms that the reference atmospheric pressure has decreased by using the determination using the first reference atmospheric pressure determination threshold value and the determination using the second reference atmospheric pressure determination threshold value together. It can be detected and returned to the appropriate reference pressure.
　電源ユニット４は、基準気圧を所定の数の気圧データ各々が示す気圧の移動平均とし、判定部４２により取得部４１が取得した気圧データが示す気圧と基準気圧との差が基準気圧更新用閾値以下であるか否かを更に判定し、更新部４３により取得部４１が取得した気圧データが示す気圧と基準気圧との差が基準気圧更新用閾値以下であると判定した場合、前記基準気圧との差が基準気圧更新用閾値以下である気圧を含めた移動平均を計算することにより基準気圧を更新する。 In the power supply unit 4, the reference pressure is set as the moving average of the atmospheric pressure indicated by each of a predetermined number of atmospheric pressure data, and the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquisition unit 41 by the determination unit 42 and the reference atmospheric pressure is the reference atmospheric pressure update threshold. When it is further determined whether or not it is the following, and it is determined by the updating unit 43 that the difference between the atmospheric pressure indicated by the atmospheric pressure data acquired by the acquiring unit 41 and the reference atmospheric pressure is equal to or less than the reference atmospheric pressure updating threshold, the reference atmospheric pressure and The reference pressure is updated by calculating the moving average including the pressure at which the difference between the two is equal to or less than the reference pressure update threshold.
　したがって、電源ユニット４は、吸引の判定に使用される基準気圧を非燃焼式吸引器１の周囲の気圧に追従させることにより、非燃焼式吸引器１の周囲の気圧が変化しても吸引を正確に判定することができる。 Therefore, the power supply unit 4 makes the reference air pressure used for determining suction follow the air pressure around the non-combustion type suction device 1, so that suction can be performed even if the air pressure around the non-combustion type suction device 1 changes. It can be determined accurately.
　電源ユニット４は、判定部４２により気圧データが示す気圧と基準気圧との差が気圧センサ故障判定用閾値を超えている気圧センサ故障状態が気圧センサ故障判定用時間を超えて継続しているか否かを更に判定し、気圧センサ故障状態が気圧センサ故障判定用時間を超えて継続していると判定された場合、電源ユニットを停止させる制御部４５を更に備える。 In the power supply unit 4, whether or not the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure by the determination unit 42 exceeds the atmospheric pressure sensor failure determination threshold value and the atmospheric pressure sensor failure state continues beyond the atmospheric pressure sensor failure determination time. Further, the control unit 45 for stopping the power supply unit is further provided when it is determined that the barometric pressure sensor failure state continues beyond the barometric pressure sensor failure determination time.
　したがって、電源ユニット４は、気圧センサ４１６Ｐが故障し、正確な基準気圧を計算することができなくなっている場合、自身の動作を停止させ、不正確な吸引の判定を停止させることができる。 Therefore, when the atmospheric pressure sensor 416P fails and the accurate reference atmospheric pressure cannot be calculated, the power supply unit 4 can stop its own operation and stop the determination of inaccurate suction.
　電源ユニット４は、判定部４２により気圧データが示す気圧と基準気圧との差が吸引検知用閾値を超えている吸引状態にあるか否かを更に判定し、吸引状態にあると判定された場合、ヒータを作動させる制御部４５を更に備える。 The power supply unit 4 further determines whether or not the difference between the atmospheric pressure indicated by the atmospheric pressure data and the reference atmospheric pressure is in the suction state exceeding the suction detection threshold value by the determination unit 42, and when it is determined that the power supply unit 4 is in the suction state. Further, a control unit 45 for operating the heater is provided.
　したがって、電源ユニット４は、非燃焼式吸引器１が吸引状態にある時にのみヒータを作動させてリザーバから供給された液体を加熱することができる。 Therefore, the power supply unit 4 can operate the heater to heat the liquid supplied from the reservoir only when the non-combustion type suction device 1 is in the suction state.
