Description

  The present invention relates to a hydrogen inhalation device and a capsule.

  In recent years, active oxygen generated in the body is said to cause diseases and aging. In order to reduce active oxygen, a health method for taking hydrogen into the body has been proposed. One method for taking hydrogen into the body is to inhale hydrogen through the mouth. Patent Document 1 describes a hydrogen suction device that sucks hydrogen generated in a hydrogen generation container using a cannula.

JP 2014-61275 A

  However, in the hydrogen inhalation device described in Patent Document 1, it is premised that a predetermined hydrogen generating agent is introduced into a container and all the hydrogen generating agent is reacted. It is difficult to react a part of the charged hydrogen generating agent. In addition, every time the inhalation is performed, it is necessary to prepare for the introduction of a hydrogen generating agent.

  The present invention has been made in view of such circumstances. An object of the present invention is to provide a hydrogen inhaler and a capsule capable of performing hydrogen inhalation in several steps once the preparatory work is performed.

  A hydrogen suction device according to the present invention includes a steam generation unit that generates steam, a storage unit that stores metal hydride, an introduction unit that introduces steam generated by the steam generation unit into the storage unit, and the steam. And a suction port for sucking in hydrogen generated by a chemical reaction with the metal hydride. When the suction port is sucked, the steam is introduced into the storage portion to generate hydrogen.

  In the present invention, when the suction port is sucked, the steam is introduced into the storage portion and hydrogen is generated. Therefore, it is possible to chemically react only a part of the metal hydride stored in the storage unit. Thus, once the metal hydride is stored, it is not necessary to store the metal hydride again until all the metal hydrides have chemically reacted. Therefore, once the preparatory work (work for storing metal hydride) is performed, it is possible to perform hydrogen suction in several times.

  The hydrogen suction device according to the present invention includes a number storage unit that stores the number of suctions by which the suction port has been sucked, and a display unit that displays that when the stored number of suctions exceeds a threshold value. And

  In the present invention, it is displayed that the number of times the suction port has been sucked is equal to or greater than the threshold value. Therefore, the user can know when to replace the metal in the storage unit with a new metal hydride.

  The hydrogen suction device according to the present invention includes a time storage unit that stores the cumulative time that the suction port has been sucked, and a display unit that displays that when the stored cumulative time is equal to or greater than a threshold value. And

  In the present invention, it is displayed that the cumulative time during which the suction port is sucked is equal to or greater than the threshold value. Therefore, the user can know when to replace the metal in the storage unit with a new metal hydride.

  The hydrogen suction device according to the present invention is characterized in that the metal hydride contains magnesium hydride.

  In the present invention, magnesium hydride is included as a metal hydride. Since magnesium hydride is chemically stable among the metal hydrides, it can be left after a part of the magnesium hydride stored in the storage portion chemically reacts with steam. Therefore, it becomes possible to react the metal hydride which has not been chemically reacted at a later time.

  The hydrogen suction device according to the present invention includes a receiving part for receiving steam, a storing part for storing metal hydride, an introducing part for introducing the steam received from the receiving part into the storing part, the steam and the hydrogen And a suction port for sucking in hydrogen generated by a chemical reaction with the metal halide. When the suction port is sucked, the steam is introduced into the storage portion to generate hydrogen.

  In this invention, since the receiving part which receives a vapor | steam is provided, various things can be utilized as a steam production | generation part.

  The capsule according to the present invention has a cylindrical shape, and includes a storage portion for storing metal hydride therein, a suction opening provided at an end of the storage portion, and an opening for taking in steam facing the suction opening. The steam generating unit that generates steam is connected to the opening at the opening.

  In the present invention, hydrogen generated by hydrolysis of a metal hydride can be sucked.

  The capsule which concerns on this invention takes in the vapor | steam produced | generated by the said vapor | steam production | generation part from the said opening part, when the pressure of the said opening part falls by the said suction opening being attracted | sucked.

It is a perspective view which shows the structure of a hydrogen inhaler. It is a block diagram which shows the structure of a control part. It is a perspective view which shows the other structure of a hydrogen inhalation device.

  Hereinafter, embodiments will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a perspective view showing the configuration of the hydrogen suction device 1. FIG. 1A is an external perspective view of the hydrogen suction device 1. FIG. 1B is an exploded perspective view of the hydrogen suction device 1. FIG. 1C is a perspective view of the capsule 10. The hydrogen suction device 1 includes a capsule 10, a cartridge 20, and an electrical component 30. The capsule 10 includes a mouthpiece 11 and a storage portion 12.

  The suction port 11 has a cylindrical shape. An exhaust filter 111 is fixed to an opening at one end of the suction port 11. The exhaust filter 111 includes activated carbon and the like. The exhaust filter 111 includes a dehumidifying and deodorizing filter whose main purpose is to remove deodorization and moisture, and a foreign matter removing filter whose main purpose is to remove minute foreign substances and bacteria. A dehumidification deodorizing filter is formed using activated carbon, for example. The main object of the foreign matter removal filter is to remove minute foreign matters and bacteria from hydrogen by adsorbing them. The foreign matter removing filter is formed using glass fiber, polypropylene, nonwoven fabric, or the like. The fine foreign matter is a substance other than hydrogen, for example, magnesium hydroxide produced when hydrogen is generated.

The storage unit 12 has a cylindrical shape. The storage unit 12 has a shape in which two cylinders having different outer diameters are connected. The portion where the two cylinders are connected has a tapered shape. The outer diameter of one end of the storage part 12 is the same as or smaller than the outer diameter of the suction mouth 11. The one end is connected to the suction port 11. The outer diameter of the other end of the storage unit 12 is smaller than the outer diameter of the one end. The storage unit 12 is formed of a heat resistant resin, for example. The upper limit of the heat resistant temperature of the resin used is at least 120 degrees Celsius. This is because steam of 100 to 120 degrees Celsius is introduced into the storage unit 12. The storage unit 12 stores magnesium hydride (MgH ₂ ) 40. An air supply filter 121 is fixed to the other end portion of the storage portion 12 facing the one end portion. The air supply filter 121 has a cylindrical shape. The outer diameter of the air supply filter 121 is the same as or larger than the outer diameter of the other end of the storage unit 12. The outer peripheral surface of the air supply filter 121 is made of, for example, an elastic resin. The air supply filter 121 is mainly intended to remove foreign matter. Inside the air supply filter 121, the same material as that of the above-described foreign matter removal filter is stored.

Magnesium hydride 40 is an example of a metal hydride. Other metal hydrides include aluminum hydride (ALH ₃ ) and calcium hydride (CaH ₂ ). Of the three metal hydrides listed here, magnesium hydride is the most chemically stable. Therefore, it is desirable to employ magnesium hydride as the metal hydride.

  The cartridge 20 has a cylindrical shape. The cartridge 20 includes an introduction part 21, a steam generation part 22, an outside air introduction port 23, a connected part 24, and a sensor part (not shown). One end of the introduction part 21 is an opening 21a. The vapor generation unit 22 includes a liquid holding unit 221 and a heater unit 222. The other end portion of the introduction portion 21 and the other end portion of the steam generation portion 22 communicate with each other inside the cartridge 20.

  The introduction part 21 is a part into which the storage part 12 is fitted. The inner diameter of the introduction part 21 is the same as or smaller than the outer diameter of the storage part 12. As a result, the capsule 10 is held in the cartridge 20 by friction between the outer peripheral surface of the storage portion 12 and the inner peripheral surface of the introduction portion 21. The storage unit 12 is shorter than the introduction unit 21. That is, when the capsule 10 is attached to the cartridge 20, a gap is formed between the steam generation unit 22 and the storage unit 12.

  The liquid holding unit 221 holds a liquid. The liquid is, for example, water or an aqueous citric acid solution. The liquid holding part 221 is, for example, a porous member impregnated with a liquid. The liquid holding unit 221 may be a liquid-absorbing polymer used for a disposable diaper, a sanitary napkin, or the like and containing a liquid. Further, the liquid holding unit 221 may be a storage of a mixture of glycerin and liquid. A heater unit 222 is disposed on the outer peripheral surface of the liquid holding unit 221. The liquid holding unit 221 is heated by the heater unit 222. The outside air introduction port 23 communicates the liquid holding part 221 with the outside. One end of the connected portion 24 is an opening 24a. The inner surface of the connected portion 24 is internally threaded. The connected portion 24 has a plurality of electrodes.

  The sensor unit includes a pressure sensor, a temperature sensor, a tilt sensor, and the like. The function of each sensor will be described later.

  The electrical unit 30 includes a control unit 31, a connection unit 32, a light emitting unit 33, and a rechargeable battery (not shown). The electrical component 30 has a shape in which two cylinders having different diameters are connected coaxially. A portion having a small diameter is the connection portion 32. The connection part 32 is shorter in length (the length corresponding to the height of the cylinder) than the other parts of the electrical component part 30. The external surface of the connection part 32 is cut off by a male screw. The connection part 32 has a plurality of electrodes.

  The control unit 31 is stored inside the electrical unit 30. The light emitting unit 33 is provided at the end of the electrical unit 30 opposite to the connection unit 32. The light emitting unit 33 has a cylindrical shape. The light emitting unit 33 has a light emitting element inside. The light emitting element is, for example, an LED (Light Emitting Diode). The rechargeable battery is, for example, a lithium ion battery. When the female screw of the connected portion 24 and the male screw of the connecting portion 32 are screwed together, the cartridge 20 and the electrical component 30 are fixed to each other. As a result, the electrode of the connected portion 24 and the electrode of the connecting portion 32 are electrically connected.

  FIG. 2 is a block diagram showing the configuration of the control unit 31. The control unit 31 includes a CPU (Central Processing Unit) 311, a ROM (Read Only Memory) 312, a RAM (Random Access Memory) 313, an I / O 314, and a timing unit 315. Each component is connected by a bus B.

  The CPU 311 controls each part of the hardware according to the control program stored in the ROM 312. The RAM 313 is, for example, SRAM (Static RAM), DRAM (Dynamic RAM), or flash memory. The RAM 313 temporarily stores data generated when the CPU 311 executes the control program.

  The I / O 314 is electrically connected to each of the sensor unit, the light emitting unit 33, and the heater unit 222. The time measuring unit 315 measures time such as time or elapsed time since the hydrogen inhaler is activated. This is a circuit that gives a time measurement result to the CPU 311 in response to a request from the CPU 311.

  Next, the operation of the hydrogen suction device 1 will be described. In the following description, it is assumed that the hydrogen suction device 1 does not have a power switch, and power is always supplied to the electrical component 30 and the like. The user sucks the mouthpiece 11. When the suction port 11 is sucked, the pressure in the vicinity of the opening of the capsule 10 to which the air supply filter 121 is attached decreases. As a result, the pressure inside the hydrogen suction device 1 decreases. This pressure drop is detected by a pressure sensor constituting the sensor unit. The CPU 311 receives the detection result via the I / O 314. The CPU 311 turns on the heater unit 222 via the I / O 314. When the user's suction is finished, the pressure inside the hydrogen suction device 1 returns to the atmospheric pressure. This pressure restoration is also detected by the pressure sensor. The CPU 311 receives the detection result via the I / O 314. The CPU 311 turns off the heater unit 222 via the I / O 314. That is, the CPU 311 turns on the heater unit 222 only while the user is sucking the suction port 11. The heater unit 222 heats the liquid holding unit 221. When the liquid holding unit 221 is heated and the user sucks the suction port 11, the heated air is introduced from the liquid holding unit 221 to the introduction unit 21. At this time, the air absorbs moisture from the liquid holding unit 221 and steam is generated. The generated steam is introduced into the storage unit 12. The vapor and the magnesium hydride 40 stored in the storage unit 12 cause a chemical reaction. This chemical reaction generates hydrogen. The generated hydrogen is taken into the body from the mouth of the user who is sucking the mouthpiece 11. Since the steam is generated and introduced into the storage portion 12 only while the user is sucking the suction port 11, hydrogen is generated only while the suction port 11 is sucked. Whether or not the suction port 11 is sucked may be detected by a gas flow sensor instead of the pressure sensor.

Magnesium hydride is a compound in which hydrogen is chemically bonded between magnesium metal atoms. Magnesium hydride has a property of decomposing while releasing hydrogen by reacting with water according to a hydrolysis reaction represented by the following formula (1). The hydrolysis reaction represented by the formula (1) generates 15.2 [wt%] hydrogen of magnesium hydride.
MgH ₂ + 2H ₂ O → Mg (OH) ₂ + 2H ₂ (1)

  In the above-described operation, the heater unit 222 is turned on only while the suction port 11 is being sucked. For example, a temperature sensor is provided in the hydrogen suction device 1. Based on the detection result of the temperature sensor, the CPU 311 controls on / off of the heater unit 222 so that the inside is kept at a predetermined temperature. Hereinafter, maintaining the inside of the hydrogen suction device 1 at a predetermined temperature is referred to as preheating. The predetermined temperature (residual heat temperature) is set to be slightly lower than the temperature at which steam is generated. When the suction port 11 is sucked, the heater unit 222 is further heated and the temperature rises, so that steam is generated and hydrogen is generated. Further, when the suction port 11 is not sucked, no steam is generated and hydrogen is not generated. When preheating is performed, it is desirable that the CPU 311 can control the current flowing through the heater unit 222. When the heater unit 222 is turned on due to residual heat and the suction port 11 is sucked, the current flowing through the heater unit 222 is increased to increase the heating capability of the heater unit 222. Thereby, even when the inside does not reach the preheat temperature, if the suction port 11 is sucked, steam can be generated.

  In order not to consume useless electric power due to the residual heat, the residual heat may be interrupted when the hydrogen suction device 1 is close to the vertical posture. Further, when the hydrogen suction device 1 becomes close to a horizontal posture, residual heat is started. Here, the vertical posture means a case where the longitudinal direction of the hydrogen inhaler 1 is a vertical direction. The horizontal posture refers to the case where the longitudinal direction of the hydrogen suction device 1 is the horizontal direction. For example, a biaxial tilt sensor is used to detect the posture of the hydrogen suction device 1.

  The hydrogen suction device 1 does not have a power switch, and the power is always supplied to the electrical unit 30 and the like, but is not limited thereto. The hydrogen suction device 1 may be provided with a power switch. In this case, as soon as the power switch is turned on, the operation of remaining heat may be started immediately.

  This embodiment has the following effects. Since the heater unit 222 is turned on only while the suction port 11 is being sucked, steam is generated only during that time. As a result, hydrogen can be generated only while the suction port 11 is sucked. That is, the chemical reaction between steam and hydrogen can be performed intermittently. The reaction can be stopped while only a part of the magnesium hydride 40 stored in the storage unit 12 is reacted. As a result, once the capsule 10 is set in the cartridge 20, hydrogen can be sucked in without replacing the capsule 10 until all of the magnesium hydride 40 has reacted. Note that the cartridge 20 is replaced when the liquid in the liquid holding unit 221 runs out.

The configuration of the cartridge 20 described above is merely an example. In the liquid holding unit 221, water or a citric acid solution can be stably held, and when heated, a material other than the porous member can hold the water or the citric acid solution as long as the material can generate steam. May be. The positional relationship between the liquid holding unit 221 and the heater unit 222 is also an example. If the generation of steam starts when the suction port 11 is sucked and the operation of stopping the generation of steam is possible when the suction is stopped, the positional relationship between the liquid holding unit 221 and the heater unit 222 can be changed. good.
Further, when water is held in the liquid holding unit 221, the storage unit 12 of the capsule 10 may store a mixture of magnesium hydride powder and citric acid powder.

Citric acid acts as a catalyst when the magnesium hydride is hydrolyzed. By adding citric acid, it is possible to increase the speed of the chemical reaction of formula (1). Magnesium hydride and citric acid undergo a chemical reaction according to the following formula (2) to generate hydrogen.
3MgH ₂ + 2C ₆ H ₈ O ₇ → Mg ₃ (C ₆ H ₅ O ₇ ) ₂ + 6H ₂ (2)

  In the hydrolysis of magnesium hydride, the reaction proceeds efficiently in the range of 70 degrees Celsius to 100 degrees Celsius. Therefore, it is desirable to adjust the temperature of the generated steam so that the temperature during the reaction falls within this temperature range. Further, it is known that in an environment of 90 degrees Celsius or less, the reaction proceeds more easily when the particle size of magnesium hydride is smaller. For example, the particle size is 5 μm.

  Instead of the steam generation unit 22, an aerosol generation unit that generates aerosol may be used. An aerosol is a substance in which solid or liquid fine particles are dispersed and suspended in a gas. The aerosol generating unit includes a holding body that holds the aerosol generating substance and a heater. The holding body is a porous member activated carbon or paper that can hold the aerosol generating substance. The aerosol generating substance is a polyhydric alcohol or a carboxylic acid aliphatic ester. The polyhydric alcohol is, for example, glycerin, propylene glycol, triethylene glycol, or tetraethylene glycol. The carboxylic acid aliphatic ester is, for example, methyl stearate, dimethyl dodecanedioate, or dimethyl tetradecanedioate. In the aerosol generating unit, when the aerosol generating substance held by the holding body is heated by the heater, the aerosol is generated. The generated aerosol is introduced into the storage unit 12. Moisture or water vapor contained in the aerosol and magnesium hydride 40 stored in the storage unit 12 cause a chemical reaction. This chemical reaction generates hydrogen. When the aerosol introduced into the storage unit 12 does not contain sufficient moisture or water vapor to cause a chemical reaction, the aerosol-generating substance and water may be mixed and held in the holding body.

(Embodiment 2)
The present embodiment relates to a form for notifying the replacement time of the capsule 10. The CPU 311 counts the number of times the heater unit 222 is turned on and stores the value in the RAM 313. In this case, the RAM 313 functions as a number storage unit. The CPU 311 compares the count value with a predetermined threshold value, and displays that the capsule 10 should be replaced when the count value is equal to or greater than the threshold value. For example, the light emitting unit 33 is blinked. For example, each time the CPU 311 detects that the suction port 11 has been sucked, the CPU 311 compares the threshold value with the count value. In addition, since the heater part 222 will be turned on if the suction opening 11 is attracted | sucked, you may consider that the frequency | count of having been turned on is the frequency | count of being attracted | sucked.

  In the present embodiment, it is displayed that the number of times the suction port 11 has been sucked (the number of times of suction) has reached a threshold value or more. Therefore, the user can know when to replace the capsule 10. The threshold value is determined through experiments.

(Embodiment 3)
The present embodiment relates to a form for notifying the replacement time of the capsule 10. The CPU 311 uses the timer unit 315 to obtain the accumulated time when the heater unit 222 is turned on and stores it in the RAM 313 or the like. In this case, the RMA 313 functions as a time storage unit. The CPU 311 compares the accumulated time with a predetermined threshold value, and displays that the capsule 10 should be replaced when the accumulated time exceeds the threshold value. For example, the light emitting unit 33 is blinked. For example, every time the CPU 311 detects that the suction port 11 has been sucked, the CPU 311 compares the threshold value with the accumulated time. The heater unit 222 is turned on while the suction port 11 is being sucked. Strictly speaking, there is a time lag from when the suction of the suction port 11 is started until the heater unit 222 is turned on, but it is a slight time as a whole. Therefore, the time when the heater unit 222 is turned on may be the sucked time.

  In the present embodiment, it is displayed that the cumulative time that the suction port 11 has been sucked is equal to or greater than a threshold value. Therefore, the user can know when to replace the capsule 10. The threshold value is determined through experiments.

  In Embodiment 2 or 3, the replacement time of the cartridge 20 may be displayed by a method similar to the method for notifying the replacement time of the capsule 10. In this case, in order to distinguish between the replacement time of the capsule 10 and the cartridge 20, it is only necessary to change the emission color of the light emitting unit 33 or change the blinking cycle.

(Embodiment 4)
The present embodiment relates to a configuration in which the steam generation unit 22 is not provided in the hydrogen suction device 1. FIG. 3 is a perspective view showing another configuration of the hydrogen suction device 1. The hydrogen suction device 1 includes a capsule 10, a joint portion 50, and an adapter 60. In this embodiment, a steam-type inhaler 200 is used as a steam generation source. Since the configuration of the capsule 10 is the same as that of the first embodiment, the description thereof is omitted.

  The joint portion 50 has a cylindrical shape. The joint part 50 includes a first fitting part 51, a receiving part 52, an introduction part 53, a second fitting part 54, a valve body 55, and a display part 56. One end of the first fitting portion 51 is an opening 51a. The other end of the first fitting portion 51 communicates with one end of the receiving portion 52. The first fitting part 51 is fitted with the adapter 60. The receiving unit 52 receives steam through the adapter 60. The other end of the receiving portion 52 and one end of the introducing portion 53 communicate with each other via a valve body 55. The other end of the introduction portion 53 communicates with one end of the second fitting portion 54. The other end of the second fitting portion 54 is an opening 54a. The capsule 10 is fitted to the second fitting portion 54. The valve body 55 is a valve that opens and closes due to a pressure difference. When the pressure of the introduction part 53 is smaller than the pressure of the receiving part 52, the valve body 55 will be in an open state. When the pressure of the receiving part 52 is smaller than the pressure of the introduction part 53, the valve body 55 will be in an open state. The display unit 56 is controlled by a control unit (not shown). The valve body 51 may be provided between the introduction part 53 and the second fitting part 54.

  The adapter 60 includes a first fitted portion 61, an air supply pipe 62, and a mounting portion 63. The first fitted part 61 includes a base part 611 and a tip part 612. The diameter of the base 611 is larger than the diameter of the tip 612. The distal end portion 612 is fitted to the first fitting portion 51 of the joint portion 50. The outer surface of the tip 612 is male threaded. The inner surface of the first fitting portion 61 is internally threaded. The female screw of the tip 612 and the male screw of the first fitting part 61 are screwed together, and the first fitted part 61 and the first fitting part 51 are fixed. The air supply pipe 62 is a hollow pipe formed of a heat resistant resin. One end of the air supply pipe 62 is connected to the first fitted portion 61. The other end of the air supply pipe 62 is connected to the mounting portion 63. The mounting portion 63 has a bowl shape. The mounting portion 63 is made of an elastic material such as rubber, for example. The attachment part 63 is attached to the vapor blowing part 201 of the inhaler 200. In addition, you may make it fix the 1st to-be-fitted part 61 and the 1st fitting part 51 with a frictional force like the capsule 1 and the coupling part 50. FIG.

  Next, the operation of the hydrogen suction device 1 will be described. The steam supplied from the inhaler 200 is received by the receiving part 52 through the air supply pipe 62, the first fitted part 61, and the first fitting part 51. The valve body 55 is closed in a steady state. The received steam stays in the receiving part 52.

  When the user sucks the suction port 11, the pressure of the introduction part 53 decreases. Since the pressure of the introduction part 53 falls below the pressure of the receiving part 52, the valve body 55 will be in an open state. The received steam further passes through the introduction portion 53 and is introduced into the storage portion 12 through the second fitting portion 54.

  The steam introduced into the storage unit 12 chemically reacts with the stored magnesium hydride to generate hydrogen. The generated hydrogen is exhausted from the suction port 11. The exhausted hydrogen is taken into the body through the user's mouth. When the user stops sucking the suction port 11, the pressure of the introduction part 53 is restored. Thereby, the valve body 55 returns to the closed state. Since no steam is introduced into the storage unit 12, no hydrogen is generated. The valve body 55 may be an electromagnetic valve, and a sensor may be used to detect whether or not the suction port 11 is being sucked, and the valve body 55 may be opened and closed based on the detection result.

  In the present embodiment, since the valve body 55 is opened only while the suction port 11 is being sucked, steam is introduced into the storage portion 12 only during that time. As a result, hydrogen can be generated only while the suction port 11 is sucked. That is, the chemical reaction between steam and hydrogen can be performed intermittently. The reaction can be stopped while only a part of the magnesium hydride 40 stored in the storage unit 12 is reacted. As a result, once the capsule 10 is set in the cartridge 20, hydrogen can be sucked in without replacing the capsule 10 until all of the magnesium hydride 40 has reacted.

  In addition, the apparatus which supplies vapor | steam is not restricted to the steam type inhaler 200. FIG. Equipment that generates steam, such as a steam-type humidifier and a steam facial device, can be used.

  Furthermore, an ultrasonic humidifier or the like that outputs spray instead of steam can be used. In this case, the temperature is lower than steam. If the temperature is low, the reaction with magnesium hydride becomes worse. In order to improve it, a heater may be provided in the joint portion 50 and the spray may be heated and then introduced into the storage portion 12. Furthermore, preheating may be performed and heating may be performed until the spray is changed to steam.

  Also in the fourth embodiment, as in the second and third embodiments, the number of times of suction and the accumulated time of suction are stored, and the replacement time of the capsule 10 can be displayed by comparing them with a threshold value. . Whether it is sucked or not is detected by a pressure sensor. Alternatively, a sensor for detecting opening / closing may be attached to the valve body 55 to detect the number of times of opening / closing the valve body 55 and the accumulated time of opening.

The technical features (components) described in each embodiment can be combined with each other, and a new technical feature can be formed by combining them.
The embodiments disclosed herein are illustrative in all respects and should not be considered as restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
