Description

  The present invention relates to a pressure adjusting device, and more particularly to an exhaust pressure releasing device.

  As an exhaust pressure relief device used in a conventional blood pressure monitor, one having a container for containing a gas therein is mainly known. In such an exhaust pressure release device, in particular, the movable valve member is abutted against the pressure release port of the container, and the exhaust amount is controlled by the interval between the valve member and the pressure release port. Thereby, it is possible to adjust the atmospheric | air pressure in a container, for example, it is used for the measurement of a blood pressure, etc.

  In the conventional exhaust pressure relief device, the valve member moves in a straight line when the valve member is detached from the pressure relief port or contacts the pressure relief port, so the distance between the valve member and each part of the pressure relief port. Are always maintained at regular intervals.

  However, when the valve member is detached from the pressure release port, the formed interval is the distance between the peripheral edge of the pressure release port and the valve member. The amount is also large. Therefore, it becomes difficult to finely adjust the exhaust gas, and the exhaust gas fine adjustment technology cannot be epoch-making.

In view of such circumstances, the inventor of the present invention has conducted research using logic, and as a result, has obtained the present invention that has a reasonable design and can effectively improve and solve the above-mentioned drawbacks. .
Accordingly, the present invention provides an exhaust pressure relief device capable of controlling the operation relationship between the valve member and the pressure relief port by controlling the swinging mode of the valve body, thereby realizing fine exhaust adjustment and low-speed exhaust. The main purpose is to do.

  In order to achieve the above object, an exhaust pressure release device according to the present invention includes a carrier having a working space and a working member provided in the working space. The carrier is further provided with a valve nozzle that communicates with the working space. The actuating member includes an axis and a valve body that controls the distance from the valve nozzle by swinging with respect to the axis.

  In the exhaust pressure release device according to the present invention, when a gap is generated between the valve body and the valve nozzle due to the swinging of the valve body, the distance changes depending on the relative distance between the valve body and the shaft center. A minute amount of gas can be exhausted at a position away from the heart, and the above-described object can be achieved.

  The features and technical contents of the present invention will become more apparent by referring to the following detailed description of the present invention and the accompanying drawings. However, it should be understood that the drawings are for reference and description only and are not intended to limit the invention in any way.

  FIG. 1 is a schematic view showing an internal structure when the exhaust pressure release device according to the first embodiment of the present invention is sealed. The exhaust pressure release device according to the present invention is connected to a container (not shown) containing gas therein and controls the opening and closing of the valve port to adjust the atmospheric pressure in the container. The exhaust pressure release device includes a carrier 1 and an operation member 2 provided on the carrier 1.

  The carrier 1 mainly includes a working space 10. The operating member 2 is installed in the operating space 10. Therefore, the carrier 1 supports the operation member 2 and is used for the operation member 2 to perform a preset operation in the operation space 10. Further, a valve nozzle 11 communicating with the working space 10 is further provided on the carrier 1. In the present embodiment, the carrier 1 is provided with an engagement hole 100 for engaging with the valve nozzle 11. The valve nozzle 11 has a valve port 110 that communicates with a container that contains gas therein and extends to the working space 10. When the pressure in the container is to be reduced, the gas in the container is exhausted from the valve port 110 by the valve nozzle 11 and can be released.

  The operation member 2 is provided in the operation space 10 of the carrier 1 and performs a preset operation. The operation set in advance is that the operating member 2 controls the opening and closing of the valve opening 110 of the valve nozzle 11 to adjust the atmospheric pressure in the container by external control (not shown). The actuating member 2 includes an axis 20 and a valve body 21 that swings with respect to the axis 20. Specifically, the actuating member 2 may include a base portion 200 that is pivotally provided on the axis 20 and a drive portion 22 that is coupled to the base portion 200. The drive unit 22 controls the valve body 21 so as to swing with respect to the shaft center 20 by controlling from the outside, for example, changing the position shift direction and the amount of position shift. The distance between the nozzle 11 and the nozzle 11 is adjusted to control the exhaust amount.

  In the present embodiment, the drive unit 22 can be oscillated and displaced in the left-right direction by the forward voltage and the reverse voltage of the power element 3. Further, the drive unit 22 may be a magnetic element having a first magnetic pole 220 and a second magnetic pole 221. The power element 3 may be a coil that generates electromagnetic induction with the drive unit 22. When forward voltage is applied to the power element 3, the drive unit 22 is displaced to one side by one magnetic pole of the coil and the magnetic element magnetic pole from the principle that the same poles repel each other due to attracting different poles. To come. And since the drive part 22 is connected with the base part 200, when it shifts | deviates to a position, it will rock | fluctuate and deviate with respect to the axial center 20, and also will make the valve body 21 perform preset operation | movement with the momentum. In the opposite case, when a reverse voltage is applied to the power element 3, another magnetic pole is generated in the coil, causing the drive unit 22 to be displaced to the other side.

  The valve body 21 may further include a valve arm 210 formed extending from the drive unit 22 and a valve cover 211 provided on the valve arm 210. As shown in FIG. 1, the valve cover 211 may be manufactured from a material such as rubber, for example, and is used to abut against the valve opening 110 of the valve nozzle 11. In this way, the valve port 110 is sealed by the contact between the rubber and the valve port 110. Further, a gap 212 is recessed at a position facing the valve cover 211 of the valve arm 210. The gap 212 corresponds to the valve port 110 of the valve nozzle 11. Therefore, the deformation amount of the valve cover 211 caused by the pressure from the valve port 110 when the valve cover 211 abuts against the valve port 110 is eliminated by the deformation space due to the gap 212, and the valve cover 211 is pressed from the valve port 110. It is possible to avoid the influence on the exhaust amount that can be adjusted and its exhaust range by concentrating the deformed portion caused by the above around the valve port 110.

  Thus, according to the above configuration, the exhaust pressure release device according to the present invention is obtained.

  As shown in FIGS. 2 and 3, when the valve body 21 is controlled to change the valve port 110 from the sealed state shown in FIG. 1 to the exhaust state, the operating member 2 is connected to the valve port 110 of the valve nozzle 11. The swinging direction of the valve body 21 is controlled by the drive unit 22 so that a minute space S is generated between the valve port 110 and the contact, and the gas in the container is exhausted from the space. The valve element 21 of the actuating member 2 generates an interval S by swinging with respect to the axis 20. Therefore, when the valve body 21 is detached from the valve port 110, the interval S, that is, the maximum interval S is formed on one side between the valve port 110 and the valve body 21 away from the axis 20. The contact between the valve body 21 and the valve port 110 is maintained to some extent on the other side close to the axis 20 between the valve port 110 and the valve body 21, that is, a minimum distance S is formed. In other words, in the low-pressure exhaust state of the exhaust pressure release device according to the present invention, the size of the interval S is not constant, and the valve body 21 and the shaft center 20 are moved by the valve body 21 swinging with respect to the shaft center 20. Varies depending on the relative distance. That is, the distance S between the valve port 110 and the valve body 21 increases as the valve port 110 moves away from the axis 20. Conversely, the closer to the axis 20 of the valve port 110, the smaller the distance between the valve port 110 and the valve body 21. According to the above feature, the interval S between the valve port 110 and the valve body 21 can be further finely adjusted, and the interval S is opened obliquely by the valve body 21. Exhaust is performed only from one side having a large interval S. By doing so, the amount of exhaust can be reduced and the purpose of fine adjustment of exhaust and low speed exhaust is achieved.

  In addition, as shown in FIG. 4, when exhausting at high speed, the interval S is increased simply by controlling the valve body 21 so as to be completely away from the valve port 110, and the exhaust amount can be increased. Reach the purpose of high-speed exhaust.

  As shown in FIG. 3, when the end surface of the valve port 110 is set to the horizontal position of the valve port 110 in order to bring the valve body 21 into close contact with the valve port 110, the horizontal position of the center position O of the axis 20 of the operating member 2 The position is closer to the valve nozzle 11 side than the end face of the valve port 110. That is, the center position O of the shaft center 20 is not located at the same horizontal position as the end face of the valve port 110. Between the connecting line connecting the end portion of the end face of the valve port 110 closest to the axis 20 and the center position O of the axis 20 and the horizontal position of the center position O of the axis 20, the included angle θ Is formed. As the included angle θ increases as a control parameter for the interval S during low-speed exhaust, the interval S increases. Further, as a preferred embodiment, it is possible to generate a positional deviation amount between the center position O of the axis 20 and the end face of the valve port 110. Note that the range of the positional deviation amount is within about 0.5 mm, and preferably 0.1 to 0.2 mm, but is not limited thereto.

  5 to 8 are views showing an exhaust pressure release device according to the second embodiment of the present invention. As shown in FIGS. 5 to 8, the valve body 21 has a sheet shape, one side of which is fixed to the valve arm 210, and the other side facing the valve body 110 and the gap 212. By doing so, the interval S between the valve port 110 and the valve body 21 can be further finely adjusted (shown in FIG. 7), and the interval S is opened obliquely by the valve body 21, thereby Since the gas in the inside is exhausted from only one side having the large interval S, the exhaust amount can be further reduced, and the purpose of fine adjustment of exhaust and low-speed exhaust can be achieved as in the above embodiment.

  In view of the above, the present invention has achieved the expected purpose of use, overcomes the drawbacks of the prior art, and has novelty and inventive step. A patent is filed based on the law. The examiner hopes that this case will be patented after detailed examination to ensure the rights of the inventor.

  While preferred embodiments of the invention have been disclosed above, they are not intended to limit the invention in any way. Various changes and modifications in the specification and drawings of the present invention belong to the scope of the protection of the present invention.
