  According to the facial instruments of Patent Documents 1 to 3, by rotating the circular adjustment knob, the carbon dioxide gas can be ejected, stopped, and further the ejection can be adjusted. Does not occur. However, in a high temperature environment, the internal pressure of the carbon dioxide gas cylinder increases, and if it is left as it is, the spray pressure and the spray amount from the spray body increase due to the abnormal pressure. The only way is to retighten the child. In particular, when the internal pressure of the cylinder is higher than a specified value in a stopped state, there is a problem that the lotion spouts at a momentum exceeding the user's expectation as soon as the circular adjustment knob is turned in the opening direction.

  If the facial device is left at a higher temperature, the internal mechanism may be damaged due to extreme abnormal pressure, or the cylinder may burst in the worst case. Not taken.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a convenient and safe regulator for a compressed gas cylinder by automatically opening an abnormal pressure when it occurs. It is.

In order to achieve the above-described object, in the present invention, the interior is partitioned into a primary side and a secondary side by a valve seat having a valve hole, and a compressed gas cylinder is attached to the primary side end, while the secondary side end A compressed gas opening / closing handle is provided so as to be rotatable in forward and reverse directions , and further, a compressed gas outlet is provided on the secondary side and an outlet for abnormal pressure is provided closer to the handle than the outlet,
A sleeve provided in the primary side of the main body having a gas flow path communicating with the valve hole;
A pin that is supported so as to be movable in the axial direction in the gas flow path of the sleeve, and that is biased in a direction to close the valve hole in a state in which a distal end portion protrudes to the secondary side through the valve hole;
A packing is provided on the outer periphery, and the inner side of the secondary side can be pressed in the opening direction against the biasing force while maintaining airtightness between the relief hole for the abnormal pressure and the valve seat by the packing. A sliding pin retainer,
A pressure adjusting spring provided between the pin press and the opening / closing handle, and compressed by an operation in the opening direction of the opening / closing handle to urge the pin holding in the opening direction of the pin;
The pin retainer used means for releasing the abnormal pressure from the escape hole by displacing the packing to a position exceeding the escape hole against the biasing force of the pressure adjusting spring by the abnormal pressure.

  The regulator of the present invention displaces the pin presser within the open / close range of the pin in conjunction with the opening / closing operation of the open / close handle. During this time, the compressed gas introduced to the secondary side through the valve hole acts on the bottom surface of the pin presser, that is, the pressing surface of the pin, and a slight change in internal pressure is absorbed by the expansion and contraction of the pressure adjusting spring, and the compressed gas is ejected. The pressure is stabilized. On the other hand, if the internal pressure rises abnormally due to temperature rise during use, the pin retainer is greatly displaced by the abnormal pressure, and the abnormal pressure is automatically released from the relief hole by displacing the packing to a position beyond the relief hole. To release.

In a higher temperature environment, the regulator may break down due to excessive abnormal pressure, or in the worst case, the compressed gas cylinder may rupture. A means is used in which a branch hole is formed in the primary side of the main body and a fusible plug is provided on the primary side of the main body. According to this means, the inner metal of the fusible plug is melted and opened by high temperature, and an excessive abnormal pressure can be automatically released to the outside.

Further, it is preferable to further provide an indicator of the remaining amount of gas that can be moved by the internal pressure on the secondary side of the main body.

Furthermore, in the present invention, the above-mentioned regulator, a spray main body provided with a cosmetic water storage cup, and a gas hose that connects one end to the outlet of the compressed gas of the regulator and connects the other end to the spray main body, Means is also used that constitutes a facial device in which the skin lotion is jetted out of the spray body by the compressed gas introduced from the regulator.

  In such a facial device, the compressed gas is preferably carbon dioxide.

  According to the present invention, when an abnormal pressure exceeding a predetermined value is generated, it is automatically released from the escape hole to the outside, which is convenient because the user does not have to retighten the opening / closing handle. , Safe. In addition, the fusible stopper functions in an abnormally high temperature environment to prevent an excessive increase in internal pressure, so that it is possible to prevent dangers such as bomb explosion.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, an example is shown in which the present invention is used as a carbon dioxide gas regulator in a carbonic acid mist facial device. FIG. 1 shows the entire facial device, in which a cylinder container V containing a carbon dioxide cylinder is connected by a gas hose P to a spray main body S with a cup for containing lotion. In use, with the upper handle H of the cylinder container V turned in the opening direction, the carbon dioxide gas guided from the cylinder container V through the hose P is drawn by pulling the trigger T of the spray body S with a finger. It can be sprayed in the form of mist from the spray body together with the inner lotion. The cylinder container V is provided with an indicator I for visually observing the remaining gas amount together with the coupler C of the hose P.

  As shown in the exploded view of FIG. 2, the cylinder container V is composed of cylindrical case bodies V1 and V2 that are divided into two vertically. Among them, the upper case body V1 is provided with the handle H, the coupler C, and the indicator I described above, and a cartridge type relatively small carbon dioxide gas cylinder B is attached to the lower opening thereof by screwing. And the upper case body V1 is equipped with the regulator of this invention. Note that the lower case body V2 is attached to and detached from the upper case body V1 when the cylinder B is replaced, and the cylinder container V is shown in FIG. Can be placed on the desk in a stable manner.

  FIG. 3 is an exploded view of the regulator R installed in the upper case body V1, and FIG. 4 is an assembled view. The main body 1 that connects the coupler C and the indicator I to the sides is used as a base, and the interior is the primary side. And a secondary part, and a control part for the valve part is configured in the lower chamber 1a and a valve part in the upper chamber 1b. Specifically, the main body 1 divides the inside of the substantially cylindrical member into a lower chamber 1a and an upper chamber 1b by a partition 1c, and the connection ports 1d and 1e of the coupler C and the indicator I are communicated with the upper chamber 1b. Each is provided. The connection port 1d of the coupler C is a carbon dioxide gas outlet. A through hole 1f is provided through the center of the partition 1c so as to penetrate vertically. The lower chamber 1a on the primary side is inserted through the through hole 1f so that a part of the upper end protrudes into the upper chamber 1b. A valve portion is configured by mounting a pin 2 and a sleeve 3 on the valve. On the other hand, the upper chamber 1b, which is the secondary side of the partition 1c, is equipped with a pin presser 4 and a pressure adjustment spring 5 so that the protruding portion of the pin 2 can be pressed downward to constitute a control unit for the valve unit. ing.

  Next, the valve part and the members constituting the control part will be described in detail. First, as shown in FIG. 3, the sleeve 3 constituting the valve portion in the lower chamber 1a of the main body 1 is provided with a gas flow path 3a vertically passing through the inside, and a packing 3b is attached to the recessed portion on the upper surface. Yes. The packing 3b functions as a valve seat using the pin 2 as a valve while airtightly adhering the upper surface of the sleeve 3 to the lower surface of the partition 1c of the main body 1. That is, the packing 3b is provided with a valve hole 3c communicating with the through hole 1f of the partition 1c of the main body 1. On the other hand, the pin 2 is supported by movement in the axial direction (vertical direction) in the gas flow path 3a of the sleeve 3, and protrudes into the upper chamber 1b of the main body 1 through the valve hole 3c, A taper portion 2c that widens toward the end is formed between the lower half portion 2b having a larger diameter than the upper half portion 2a, and the taper portion 2c airtightly closes the valve hole 3c of the packing 3b from below. . For this reason, in this embodiment, the shape of the lower opening in the valve hole 3 c is tapered corresponding to the tapered portion 2 c of the pin 2. In this embodiment, the upper opening of the valve hole 3c is also tapered, but this ensures communication between the valve hole 3c and the through hole 1f of the main body 1 at the interface between the packing 3b and the partition 1c. This is because the carbon dioxide gas is efficiently sent to the upper chamber 1b.

  In this way, the pin 2 is such that the tapered portion 2c airtightly closes the valve hole 3c of the packing 3b from below, but in order to assist this operation, the lower half 2b of the pin 2 has a receiving portion for the spring 6. 2d is provided to urge the pin 2 in the valve closing direction.

  More specifically, the spring 6 uses the filter 8 built in the opening member 7 of the carbon dioxide cylinder B that is screwed into the lower chamber 1a of the main body 1 as a receiving portion on the lower end side, and the pin 2 is in the valve closing direction, that is, upward. Energize.

  Here, the unsealing member 7 has a connecting projection 7a that breaks through the sealing film at the mouth of the carbon dioxide cylinder B at the bottom, and introduces carbon dioxide into the gas introduction hole that communicates with the gas flow path 3a of the sleeve 3. 7b is formed. Further, a sintered metal filter is adopted as the filter 8 built in the opening member 7.

  Reference numeral 9 denotes a cylinder mounting member for mounting the carbon dioxide gas cylinder B by screwing. The cylinder mounting member 9 is positioned below the opening member 7 and is screwed into the lower chamber 1a of the main body 1 through the ring-shaped packing 10 and assembled. It is

  Then, the structure of the control part of the valve part in the upper chamber 1b of the main body 1 is explained in full detail. The control unit slides up and down in the upper chamber 1b, and pushes the tip of the upper half 2a of the pin 2 protruding into the upper chamber 1b downward, and above the pin press 4 The pressure adjusting spring 5 is provided, and a rod-shaped pushing portion 12 that moves the pressure adjusting spring 5 up and down in a compressible manner between the pin holder 4 and a spring receiver 11. A ring-shaped Y packing 13 is provided on the outer periphery of the pin retainer 4 and is airtightly attached to the upper chamber 1b. In the case of this embodiment, the handle H is attached to the upper portion of the main body 1 in a cap shape and can be rotated forward and backward by screws or the like. A push-in portion 12 is provided inside the top surface of the handle H, and the handle H The pushing portion 12 is moved up and down in conjunction with the forward and reverse rotation operations.

  In the regulator R having the above-described configuration, the feature of the present invention is that the abnormal pressure is automatically released, which will be described later, and the basic operation in normal time will be described first.

  The state in which the handle H is closed in the closing direction is as shown in FIG. 4. At this time, the handle H is located on the uppermost side, the pressure adjustment spring 5 is also uncompressed, and the pin 2 on the lower chamber 1a side is also pin-pressed 4 Not pushed by. Accordingly, the valve hole 3c of the packing 3b is closed by the taper portion 3c of the pin 2, and the ejection of carbon dioxide gas is stopped.

  On the other hand, when the handle H is turned in the opening direction, as shown in FIG. 5, the pushing portion 12 is lowered in conjunction with this, and the pressure adjusting spring 5 is compressed. The pin presser 4 is urged downward by this compression force, and the pin 2 is pushed downward against the spring 6. When the pin 2 is pushed downward, a gap is formed between the valve hole 3c (the lower surface side tapered portion) of the packing 3b and the pin 2 (the tapered portion 2c). This gap becomes a flow path for carbon dioxide gas, and an amount of carbon dioxide gas corresponding to the size of the gap flows into the upper chamber 1b through the through hole 1f of the partition 1c, but the rotation amount of the handle H in the opening direction is large. As the pin 2 is lowered, the clearance between the valve holes 3c is also increased. However, if the rotation of the handle H in the opening direction is allowed indefinitely, the pin presser 4 comes into contact with the partition 1c and closes the through hole 1f. It is preferable to regulate.

  The arrows in FIG. 5 indicate the flow of carbon dioxide gas, but there are extremely narrow channels on the way, so that the explanation will be given again with reference to FIG. Carbon dioxide flows along the route. That is, the carbon dioxide gas in the carbon dioxide cylinder B is formed by the gas introduction hole 7b of the opening member 7, the filter 8, the gap between the gas flow path 3a in the sleeve 3 and the pin 2, the gap between the valve hole 3c and the pin 2 in the packing 3b, and the partition 1c. Flow through the through holes 1f, the space formed by the upper surface of the partition 1c in the upper chamber 1b and the lower surface of the pin presser 4, and the connection ports 1d and 1e in this order. In particular, the gap in the tapered portion of the gap between the pin 2 and the valve hole 3c is extremely narrow. This is because the carbon dioxide gas is decompressed and ejected in a mist form by the principle of the needle valve.

  The carbon dioxide gas flowing into the connection port 1d of the coupler C is guided to the spray body S through the hose P connected to the coupler C, and the lotion is mixed by pulling the trigger T of the spray body S as described above. Sprayed as carbonated mist.

  On the other hand, the indicator I is urged outward from the main body 1 by the pressure of the carbon dioxide gas flowing into the connection port 1e of the indicator I. Therefore, when carbon dioxide is sufficiently left in the carbon dioxide cylinder B, the indicator I is more urged, and the remaining amount may be sufficient by observing the position of the indicator ring provided at the tip. I can confirm.

  Here, the function of the pressure adjustment spring 5 will be described. In the valve open state of FIGS. 5 and 6, the pressure adjustment spring 5 expands and contracts so as to balance with the internal pressure of the upper chamber 1b. Therefore, when the internal pressure of the upper chamber 1 b increases due to a change in room temperature or the like during use of the carbonic acid mist, an upward force acts on the pin retainer 4 with its lower surface as the pressure receiving surface, and the internal pressure is applied to the pressure adjusting spring 5. When exceeding the urging force, the pin presser 4 raises the upper chamber 1 b while compressing the pressure adjusting spring 5. When the pin presser 4 is raised, the pin 2 is also raised in conjunction with this, whereby the opening of the valve hole 3c is reduced, and excessive ejection of carbon dioxide can be suppressed. When the internal pressure of the upper chamber 1b is restored, the pressure adjusting spring 5 urges the pin presser 4 downward to lower the pin 2 so that the carbon dioxide gas ejection amount is always constant.

  In this way, in normal times, a slight pressure change is absorbed by the expansion and contraction of the pressure adjustment spring 5, and the ejection amount of the carbon dioxide gas is kept constant. However, when a high abnormal pressure exceeding this range occurs, the pressure adjustment spring The pin retainer 4 rises as the distance from the pin 2 increases while compressing 5 greatly. In this state, since the pin 2 is in the valve closing position shown in FIG. 4, the valve hole 3c is completely closed, and the abnormal pressure is accumulated in the regulator R without being released. It is.

  Therefore, in the present invention, the abnormal pressure that continues even after the valve is closed is released to the atmosphere. As a means for this, as shown in FIG. 7, a relief hole 14 is provided at a predetermined position in the upper chamber 1b of the main body 1. Provided. FIG. 7 shows a cross section when the main body 1 is rotated 90 degrees from the state of FIGS. As shown in FIGS. 8 and 9 showing the open / close state during normal times, the escape hole 14 is normally closed by a Y packing 13 provided in the pin retainer 4 to prevent communication between the upper chamber 1b and the atmosphere. Yes.

  In such a configuration, when an abnormal pressure is generated in the upper chamber 1b, the pin presser 4 is pushed up until the Y packing 13 is positioned above the escape hole 14, as shown in FIG. Are automatically released to the atmosphere through the escape hole 14. At this time, the pin 2 rises with the rise of the pin presser 4 and the valve is closed, but if the pressure in the upper chamber 1b returns to normal due to the release of the abnormal pressure described above, the restoring force in the extending direction of the pressure adjusting spring 5 Thus, the pin 2 as well as the pin presser 4 is restored to the normal position.

  The abnormal pressure as described above is generally generated in a high temperature environment. However, if the regulator R is left in a closed state in an extremely high temperature environment of about 70 degrees, an extreme abnormal pressure is generated, and the regulator R There is not only a failure but also a danger that the carbon dioxide gas cylinder B bursts.

  As a countermeasure against this, in the present invention, as shown in FIG. 11, the sleeve 3 is provided with a branch hole 3d that branches the middle of the gas flow path 3a to the side and communicates with the lower chamber 1a, as shown in FIG. In addition, a fusible plug 15 that leads to the lower chamber 1 a is provided on the side of the main body 1. The fusible plug 15 is formed by filling and solidifying a metal that melts at a predetermined temperature in a hole that communicates with the inside and outside, and when the temperature exceeds a certain temperature, the metal dissolves to release the abnormal pressure from the hole to the outside. It is also called a fusing plug or a safety plug.

  In this configuration, as shown in FIGS. 8 and 9, the fusible stopper 15 is closed by the filling metal during normal times, and can be used as usual. Further, as shown in FIG. 10, the fusible stopper 15 does not function even when an abnormal pressure accompanied by opening from the escape hole 14 occurs unless the ambient temperature becomes a certain level or higher. In other words, the fusible plug 15 depends on the ambient temperature of the regulator R, and only when the temperature exceeds a certain level, the filler metal of the fusible plug 15 melts and communicates the lower chamber 1a with the outside air. To demonstrate. At this time, naturally, the internal pressure of the carbon dioxide gas cylinder B is extremely increased due to the high temperature environment. However, as shown by the arrow in FIG. 12, such an extreme abnormal pressure is generated from the branch hole 3d of the sleeve 3 to the lower chamber 1a. Thus, the metal of the fusible plug 15 is released to the outside air through the gap formed by melting, thereby preventing the failure of each part and the explosion of the carbon dioxide gas cylinder B.

  Since the regulator of the present invention sprays compressed gas, it is suitable for a carbonated mist facial device. However, the compressed gas ejection mode can be changed by changing the size of the pin and the valve hole, so the compressed gas is used. It can be widely used for other devices.
