Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a water supply amount adjustment structure of a water supply device suitable for supplying water to potted plants and plants in the ground.

[Conventional technology and its issues]

Various types of water supply devices have been proposed in the past, but the problem is that
If a small amount of water supply (less than 300 cc per day) is required, the question is how to maintain that amount. Furthermore, no definitive device has been found for adjusting the amount of water supplied.

Among these methods, a common method for maintaining a small amount of water supply is to fill water supply pipes with fibers, etc.
65630), this method may cause the filling to become clogged with dirt and the like, making it impossible for water to pass through (the more tightly packed the container is to limit the amount of water supplied, the more likely this is to happen).

In addition, to adjust the amount of water supplied, Japanese Utility Model Application Publication No. 59-77873 shows a method using a control valve similar to that installed in a normal water pressure circuit, but this also raises concerns about clogging. The problem is whether a very small amount can be secured. In addition, JP-A-61
Publication No. 192219 shows an example of using a device similar to the drip amount adjuster of a medical drip device that holds down the water supply tube and limits the amount of water that passes through it, but this also requires delicate amount adjustment. There are concerns about whether it will be possible and whether it will be difficult to operate.

[Means for solving the problems]

Therefore, this invention is a water supply amount adjustment structure of a water supply device in which a water supply pipe is connected to a water supply container, in which a small-diameter through hole is formed at the starting end of the water supply pipe in the water supply container, communicating the inner and outer peripheries. The above problems have been solved by providing a structure for adjusting the amount of water supplied to a water supply device, which is formed by replacing an upwardly convex water supply cap.

[Effect]

By taking the above measures, the water supply cap has a small diameter through hole through which a small amount of water can pass. By making this water supply cap convex, its surface area is increased.
Even if the holes (through holes) are a little small, they don't get clogged and allow water to pass through. Furthermore, since this water supply cap can be easily replaced, by varying the diameter and number of through holes formed in it, a simple and reliable water supply amount adjustment structure can be realized.

〔Example〕

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

Fig. 3 is a perspective view of the water supply device, and Fig. 4 is a side view of the water supply device. It consists of a water supply pipe 3 that leads to the location.

The water supply container 2 may be in the form of a medical drip bag made of soft vinyl resin or the like. That is, two sheets are overlapped, the top and bottom edges are made to have a certain width, and the side edges are sealed by sealing the edges as they are.
It is a bag-shaped container (however, as will be described later, only the water supply pipe 3 is inserted into the lower end). Furthermore, a hanging hole 4 is provided at the top for hanging by hand or from a hook, and a scale 5 is provided to indicate the amount of water stored inside. Note that water is injected through an inlet 6 provided at the top (always covered with a cap 7).

The water supply pipe 3 is also made of a flexible material such as vinyl material, and is connected to the lower end of the water supply container 2. One or more water supply pipes 3 are provided, and the length thereof is also set appropriately. The tip of the water supply pipe 3 is led to an object 8 to be watered, such as a flowerpot.

FIG. 1 is an enlarged cross-sectional view showing a structure 9 for adjusting the amount of water introduced into the water supply pipe 3. It is covered with a water supply cap 10.

In short, this water supply cap 10 may be a filter-like structure with a through hole 11 of an extremely small diameter as shown in FIG. It has an upwardly convex shape, and has a large number of through holes 11 formed on its surface to communicate the inner and outer peripheries. Then, this is fitted into the starting end of the water supply pipe 3 from above and fixed. In order to make this easier and more reliable, it is conceivable to provide a step 12 on the inner periphery of the starting end of the water supply pipe, and to fit the water supply cap 10 against this step. FIG. 2 is a cross-sectional view of the water supply cap 10 having a convex shape. Various types with different diameters and numbers of through holes 11 are prepared in advance by color coding, etc., to suit the required water supply amount. Replace and use as appropriate. In addition,
The water supply cap 10 is replaced by inserting one's hand into the water supply container 2 through the inlet 6.

By the way, regarding the operation of this water supply device 1, if you fill the water supply container 2 with water from the inlet 6 and extend the end of the water supply pipe 3 to the desired object 8, the rest is automatic. water supply. The water for water supply is not just water; it goes without saying that nutrients, sterilizers, etc. may be mixed in as needed. Incidentally, in order to prevent water from being discharged from unused water supply pipes 3 when pouring water into the water supply container 1 or from discharging water from unused water supply pipes 3, the necessary water supply pipes 3 may be held with something like a clip. Furthermore, if the water supply container 1 is made of a flexible vinyl material, the volume of the air chamber formed above the water surface in the water supply container 1 decreases as the water surface decreases, so the air pressure also decreases. There is no drop in water supply, and the amount of water supplied remains the same. However, if the water supply container 1 is made of a rigid or semi-rigid body, air must enter there, so a small air hole or the like may be provided in the cap 7 or the like. In addition, in order to ensure a small amount of water supply, it is of course necessary to make the diameter of the through hole 11 small, but in such a case, the water supply cap 10 should be made of something like unglazed pottery that allows water to penetrate. It is also possible to use it as a substitute.

[Effect of idea]

As mentioned above, this idea is as follows.
That is, a water supply cap 10 having a simple structure in which only a large number of through holes 11 are formed on the circumferential surface is fitted onto the starting end of the water supply pipe 3 in the water supply container 1, and the diameter and number of the through holes 11 are further adjusted. Various water supply amounts can be set by simply replacing the various types as appropriate. Therefore, the water supply amount adjustment structure 9 can be implemented at low cost, and operations such as replenishing water to the water supply container 1 and replacing the water supply cap 10 are easy, so anyone can use it easily.

If the water supply cap 10 is formed into the above-described upwardly convex shape, the surface area can be increased and the through hole 1 can have a small diameter.
1 can be secured in large numbers, and one through hole 1 can be secured.
Since the amount of water passing through the tube is small, there is less clogging. Furthermore, due to the unique shape of the upwardly convex shape, it is difficult for the penetrating water to concentrate on each through hole 11, and there is less clogging from this surface.
