Japanese Patent Laid-Open No. 11-5078

  By the way, when mixing such a liquid, which is a medicine, with water, for example, if a liquid such as a colloid solution that separates vertically is used, the following problems occur. That is, when a liquid that causes precipitation is stored in the liquid storage tank, the precipitate stays downward with the passage of time, and a liquid with a low specific gravity such as a supernatant liquid separates upward. For this reason, when the liquid is discharged in such a separated state, first, the sediment precipitated in the lower part is discharged first, and then a liquid having a relatively low specific gravity such as a supernatant liquid is discharged. . Thereby, even if it mixes with water in a water pipe, a density | concentration difference will be produced with progress of time. Furthermore, if sediment with a high specific gravity is discharged first, clogging may occur between the liquid storage tank and the connecting pipe when the liquid is discharged from the liquid storage tank.

  Therefore, the present invention has been made paying attention to the above-mentioned problem, and when a liquid that is separated over time is poured into a water pipe or the like, the liquid is uniformly stirred into the water pipe or the like. It is an object of the present invention to provide a liquid mixing apparatus that can be injected.

  That is, in order to solve the above-mentioned problem, the present invention includes a liquid storage tank that stores a second liquid for mixing with the first liquid flowing in the conduit, and the second liquid discharged from the liquid storage tank. In the liquid mixing apparatus for discharging the liquid to the conduit and mixing with the first liquid, the stirring member for stirring the second liquid stored in the liquid storage tank, and the stirring member is driven in the liquid storage tank And a drive mechanism.

  If comprised in this way, since the liquid which is easy to isolate | separate can be stirred in a liquid storage tank, it can stir to a uniform density | concentration and can discharge a liquid to the insides, such as a water pipe. Further, by stirring the liquid in the liquid storage tank, clogging is not caused in the pipe when the liquid is discharged from the liquid storage tank.

  Moreover, as one aspect in such an invention, a drive mechanism for driving the stirring member is provided in a lid part detachably provided in the upper part of the liquid storage tank.

  In this way, when a liquid that does not need to be stirred (for example, a liquid that is not separated) is put into the liquid storage tank, it can be dealt with by replacing the lid with another lid, and the liquid is stirred strongly. When a necessary liquid is added, it can be handled by replacing the lid with a stirring member having a strong stirring force.

  Furthermore, when driving such a stirring member, a drive mechanism that rotates the stirring member in a clockwise direction and a counterclockwise direction is used.

  In this way, it is possible to solve the problem that a substance having a high specific gravity is attracted to the vicinity of the outer peripheral portion by the centrifugal force generated by the rotation of the stirring member, and the liquid is separated to the vicinity of the outer peripheral portion.

  Moreover, in another invention, what drives a stirring member based on the flow in a conduit | pipe is used as a drive mechanism.

  Among these inventions, if the fluid flow can be used for stirring, it is not necessary to use a drive mechanism such as a motor, and the liquid is stirred semi-permanently without the need for periodic maintenance such as battery replacement. To be able to.

  Further, when configuring the drive mechanism in such an invention, a shaft member provided between the conduit and the liquid storage tank, and a shaft provided by the force of the fluid provided in the conduit side of the shaft member and flowing in the conduit. A first rotating member that rotates the member and a second rotating member that stirs the second fluid on the liquid storage tank side of the main shaft are provided.

  If it does in this way, the 1st rotation member will be rotated by the flow of the fluid in a conduit, and in connection with this, the 2nd rotation object may be rotated and the 2nd fluid in a liquid storage tank may be stirred. Therefore, stirring according to the strength of the flow can be performed.

  In addition, the drive mechanism includes a shaft member provided between the conduit and the liquid storage tank, and a support member that pivotally supports the shaft member so that the shaft member can be driven by the force of fluid flowing through the conduit. Is swung to agitate the second fluid in the liquid storage tank.

  If comprised in this way, since a shaft member can be rock | fluctuated irregularly by the flow of the fluid which passes along a conduit | pipe, it can agitate a 2nd fluid irregularly by the liquid storage tank side by this movement. become.

  As described above, according to the present invention, the liquid storage tank storing the second liquid for mixing with the first liquid flowing in the conduit is provided, and the second liquid discharged from the liquid storage tank is supplied to the conduit. In the liquid mixing device that discharges and mixes with the first liquid, a stirring member that stirs the second liquid stored in the liquid storage tank, and a drive mechanism that drives the stirring member in the liquid storage tank. Since it was made to provide, the 2nd liquid which is easy to isolate | separate can be stirred in a liquid storage tank. Moreover, when the second liquid is discharged from the liquid storage tank by the stirring of the second liquid, clogging is not caused in the pipe.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a liquid mixing device 1 in the first embodiment, and FIG. 2 is a diagram showing a liquid storage tank 4 attached to the liquid mixing device 1.

  The liquid mixing apparatus 1 in this embodiment uses a mixture of a medicine 6 such as a disinfectant solution in water flowing through a water pipe 2 at a certain ratio. For example, a medical site such as dentistry or surgery, a humidifier. It is used in places where humidification and sterilization, antibacterial, sterilization, etc. in indoor spaces are performed, in restaurants and in general household cooking areas. Of these, in dentistry, etc., when performing treatment in the oral cavity, the patient's saliva or blood may adhere to the treatment device such as a drill. In order to enable spraying, the liquid mixing apparatus 1 is attached to a water pipe to which a treatment instrument is connected. In addition, when humidifying or sterilizing air in a general home, a hall, a vehicle indoor space, or the like, a sprayer is attached to the tip of a pipe extending from a water pipe so that a liquid mixed with a medicine can be sprayed. Further, when it is necessary to sterilize, antibacterial, and disinfect dishes such as tableware and cooking utensils in a kitchen such as a restaurant, the liquid mixing device 1 is attached to a water pipe in such a washing place so that it can be used. In addition, in a site where sterilization, antibacterial, sterilization, and the like are performed using the liquid to be used, such a liquid mixing device 1 is attached to the water pipe 2 so that it can be used.

  The configuration of the liquid mixing apparatus 1 will be described. As shown in FIG. 1, the liquid mixing device 1 is used by being connected to a water pipe 2, and is used for mixing with the connecting pipe 3 connected to the water pipe 2 and the water in the water pipe 2. The liquid storage tank 4 for storing the medicine 6 and the liquid injection pipe 5 for discharging the medicine 6 discharged from the liquid storage tank 4 to the connecting pipe 3 are characteristically provided. 4, a stirring member 7 for stirring the drug 6 and a drive mechanism 8 for rotating the stirring member 7 are provided.

  As shown in FIG. 2, the liquid storage tank 4 is constituted by a bottomed cylindrical member. The liquid storage tank 4 can store the medicine 6 therein, and has a lid 41 screwed on the upper side. The medicine 6 is prevented from spilling due to stirring. As this chemical | medical agent 6, the aqueous solution etc. which have dolomite ore powder can be used, for example. This drug 6 is used by pulverizing dolomite ore powder, which is a mixture of calcium carbonate and magnesium carbonate, to 0.3 μm to 0.5 μm and diluting in water (“An antiviral dolomite is added. Application development of processed new materials "(Industry-Academia-Government Collaboration Journal Vol.2 No.9 2006)) It has strong sterilization, antibacterial, sterilization and other effects. By the way, when this chemical | medical agent 6 is left for a fixed time, the finely grind | pulverized calcium salt, magnesium salt, etc. will precipitate below. Therefore, a stirring member 7 and a driving mechanism 8 for stirring the medicine 6 are provided.

  The stirring member 7 is formed by hanging a rod-like or flat long member or the like down to the vicinity of the bottom surface, and is driven to rotate by a motor 81 attached to the upper portion of the lid portion 41. The motor 81 is driven by a battery (not shown), and rotates the stirring member 7 clockwise and counterclockwise at regular intervals by a timer. At this time, if the drug 6 is rotated by the stirring member 7, a precipitate having a high specific gravity moves to the outer peripheral portion of the liquid storage tank 4, and uniform stirring cannot be performed. Thus, in this embodiment, the liquid reservoir 4 is provided with an upright portion 42 for rotating the medicine 6 clockwise and counterclockwise and causing turbulent flow in the medicine 6 flow. ing. The standing portion 42 is provided so as to stand up from the bottom surface or the side surface of the liquid storage tank 4, and causes turbulence in the flow of the medicine 6 rotated by the stirring member 7. Accordingly, the medicine 6 is more uniformly stirred by the forward and backward rotations by the stirring member 7 and the standing part 42.

  Then, after the drug 6 is stirred in the liquid storage tank 4 in this way, the drug 6 is discharged to the connecting pipe 3 through the liquid injection pipe 5. At this time, a flow rate adjustment valve 51 is provided in the middle of the liquid injection pipe 5, and the flow rate of the drug 6 is adjusted by opening and closing the flow rate adjustment valve 51.

  Thus, the medicine 6 discharged from the liquid injection pipe 5 is mixed with tap water in the connecting pipe 3. At this time, in order to mix the medicine 6 with tap water efficiently, the turbulent flow generating member 31 is provided in the connecting pipe 3. The turbulent flow generating member 31 is configured to transition the flow in a rectified state to a turbulent flow, and has a simpler configuration, in which a rod-shaped member or a mesh-shaped member is provided in the pipe. Further, the turbulent flow generation member 31 is provided on the downstream side of the connection portion of the liquid injection pipe 5. When the turbulent flow generating member 31 is provided upstream of the connection portion of the liquid injection tube 5, the pressure at the connection portion with the liquid injection tube 5 fluctuates, and the drug 6 is discharged from the liquid injection tube 5 in a non-uniform state. Because it will end up. For this reason, in this embodiment, the turbulent flow generation member 31 is provided on the downstream side of the connecting portion so that the discharge amount of the medicine 6 can be made constant, and the discharged medicine 6 can be efficiently diffused. ing.

  As described above, according to the first embodiment, since the stirring member 7 is rotated by the motor 81 and thereby the drug 6 is stirred in the liquid storage tank 4, the drug 6 is supplied to the water pipe at a uniform concentration. 2 can be discharged. Further, since the medicine 6 is agitated, clogging does not occur in the liquid injection tube 5.

  In addition, since the motor 81 and the stirring member 7 as the driving mechanism 8 are provided on the removable lid 41, a medicine that does not need to be stirred (for example, a medicine that is not separated) is put into the liquid storage tank 4. Can be dealt with by replacing the lid 41 with another lid, and when a drug that needs to be vigorously stirred is added, it can be replaced with the lid 41 having the stirring member 7 having a strong stirring force. It will be possible to respond. In addition, when a failure occurs in the motor 81, it is possible to deal with it easily and at low cost by replacing only the lid 41.

Furthermore, when the stirring member 7 is driven, the stirring member 7 is rotated in the clockwise direction and the counterclockwise direction. Therefore, when a part of the drug 6 having a high specific gravity is put in the liquid storage tank 4, the stirring member 7 The problem that the drug 6 having a high specific gravity is attracted to the outer peripheral portion by the centrifugal force caused by the rotation can be solved, and the drug 6 can be uniformly stirred.
<Second Embodiment>

  Next, the liquid mixing apparatus 1 in the second embodiment will be described with reference to FIG. The liquid mixing apparatus 1 in the second embodiment is configured to stir the drug 6 in the liquid storage tank 4 using the flow of water in the water pipe 2.

  The first rotating body 71 is configured by symmetrically attaching hemispherical members, and rotates the shaft member 70 in one direction by the flow of tap water. The shaft member 70 is supported by the support portion 54 in a state where a certain gap is provided between the shaft member 70 and the liquid injection tube 5. When the shaft member 70 is supported by the support portion 54, the medicine 6 cannot be discharged if the gap is reduced, so that the medicine 6 can be passed as shown in FIG. The shaft member 70 can be rotatably supported. Specifically, a ring portion 53 is provided at the center of the four wire rods 52 provided in the radial direction so as to rotatably support the shaft member 70, thereby allowing the drug to be discharged from the gap between the wire rods 52. Yes.

  On the other hand, the second rotator 72 provided on the liquid storage tank 4 side is configured by providing a member for stirring the drug 6, for example, configured by symmetrically attaching hemispherical members. . The shape of the second rotating body 72 may be a rod-shaped member or a member having another shape. When the second rotating body 72 is rotated, the drug 6 in the liquid storage tank 4 rotates in a certain direction as in the first embodiment, and the sediment having a high specific gravity is attracted to the outer peripheral portion. There is a possibility. For this reason, as in the first embodiment, a standing portion 42 for causing turbulent flow is provided to stir the drug 6.

As described above, according to the second embodiment, the first rotating body 71 is rotated using the flow of the fluid, and thereby the second rotating body 72 provided on the opposite side of the shaft member 70. Since the medicine 6 is stirred by rotating the, the stirring operation according to the strength of the flow can be performed.

The swing member 73 is attached so as to have a slight gap between the liquid injection tube 5 and, for example, a support portion 54 having a ring portion 53 at the center of the wire 52 as shown in FIG. The swing member 73 is swung with the support portion 54 as a fulcrum.

  The operation of the liquid mixing apparatus 1 configured as described above will be described. Water flowing through the water pipe 2 flows into the connecting pipe 3 and hits a flat portion 73a provided on the lower end side of the swing member 73. . At this time, the water flows in either direction by the flat portion 73a, and the flat portion 73a swings irregularly with the change of the flow. As a result, the flat portion 73b provided on the upper end side of the swing member 73 swings, and the medicine 6 in the liquid storage tank 4 is agitated irregularly.

  If such a structure is used, since the water in the liquid storage tank 4 can be stirred irregularly without rotating, the medicine 6 can be stirred in a more uniform state.

  In this embodiment, the flat portion 73a on the lower end side is swung by the force of water, but in order to make this swing more irregular, the upstream side of the flat portion 73a of the connecting pipe 3 is used. A turbulent flow generator (not shown) for causing turbulent flow may be provided. As this turbulent flow generating portion, as a simpler configuration, a protrusion protruding inside the connecting pipe 3 may be provided as shown in FIG. In this way, the flow in the water pipe 2 becomes turbulent due to the protrusion, and the flat portion 73a can be oscillated in small increments by this turbulent flow.
