Abstract

(57) [Abstract] In the present invention, a liquid can be discharged for a very small amount of time without being affected by atmospheric pressure by utilizing the capillary phenomenon of porous fibers. PROBLEM TO BE SOLVED: To provide an excellent device for easily and effectively discharging a small amount of liquid by utilizing a capillary phenomenon of a porous fiber and a porous material. A fibrous discharge medium (2) having pores is provided in a first discharge port (1) provided in a part of a contact plate (4) to utilize a capillary phenomenon. Air enters in a bubble form from the air port (3) provided in the pair of the first discharge ports, and the liquid is discharged to the outside by adjusting the pressure between the inside and the outside of the container.

Description

[Detailed description of the invention]         [0001]     [Technical field to which the invention belongs]   The present invention relates to a liquid micro-discharge device.         [0002]     [Prior art]   For example, a high-precision pump is used to discharge a small amount of liquid of 5 ml or less per minute. I was On the other hand, a drip device or the like is frequently used as a method not using a pump or the like.         [0003]     [Problems to be solved by the invention]   However, when the high-precision pump is used, the equipment cost is high, and for example, For example, it is inconvenient to use it for watering houseplants in ordinary households. Requires a separate holding device to hold the liquid container. There was a problem that much time and labor were required. Liquid trace by the present invention Inexpensive and simple liquid by combining the discharge device and the simple holding device that can be attached An object of the present invention is to realize a micro-discharge device, which solves the above-mentioned problem.       [0004]     [Means for Solving the Problems]   The present invention is provided at an opening of a liquid container to discharge a small amount of liquid. A contact plate (4) provided so as to be in close contact with the mouth and having an air port (3); A first discharge port (1) provided in a part of the liquid and one of the liquids inserted into the first discharge port Fibrous ejection medium (2) penetrating the edge and having micropores inside and below the close-contact plate A second discharge port (6) that is provided in the section and discharges the liquid dropped from the discharge medium to the outside of the container. ), A part of which is inserted into the second discharge port, and is A small amount of liquid consisting of an open / close knob (5) that moves up and down and fits to open and close the second discharge port Simple operation and light weight are realized by providing the structure of the discharge device. It is to solve the above-mentioned problem.         [0005]     [Embodiment of the invention]   The present invention relates to a capillary phenomenon caused by a porous fibrous discharge medium (2) having fine pores. It is possible to discharge a very small amount of liquid of 5 ml or less per minute by utilizing.         [0006]   In the present invention, the size of the diameter of the first discharge port (1) (inner diameter 4 to 6 mm) and the fineness Capillary phenomenon of porous fibrous discharge medium (2) with pores and air from second air port The pressure inside the container creates the same pressure as the outside by the intrusion of one or two bubbles. As a result, a small amount of liquid can be discharged. At this time, the air in the container is Although the pressure becomes low and the liquid hardly comes out, the empty space becomes larger than the diameter (3 to 4) of the second air port (3). The air is in the form of one or two bubbles, and the same pressure as the outside makes it easier to discharge. It has become easier and overcomes this.         [0007]   The liquid micro-discharge device of the present invention is opened and closed by an external force as shown in FIG. When (5) is pushed up, a minute amount of liquid is discharged. The ejection medium (5) of the present invention is a fibrous material having micropores of 0.5 mm or less. Although loofah fibers are used here, natural fibers and synthetic fibers may be used. Porous The use of fibers (similar materials such as fibers of hemchima) enables the discharge of a small amount of liquid. Was.         [0008]       [Effect of the invention]   The liquid micro-dispensing device of the present invention can easily perform micro-irrigation for a long time without human intervention. It is thought that parts can be easily procured, and that it has excellent practicality.
