  FIG. 10 shows a third embodiment. FIG. 10A is a side sectional view of the liquid supply mechanism, and FIG. 10B is a view seen from above. The third embodiment has substantially the same configuration as the liquid supply mechanism (1) as an automatic irrigation apparatus using the plant cultivation container (37) shown in FIGS. 7 to 9, but the usage is moisture for pets. Used for supply. The difference between the configuration of the third embodiment and the second embodiment is that the third embodiment does not require a pot tray (36) and a plant cultivation container (37), and the liquid level control is an accommodation section ( 31) It is a point that is actively controlled using a floating body regardless of the atmospheric pressure related to the liquid level in the tank and the pressure balance in the reservoir (2). Other configurations are the same as the configuration of the liquid supply mechanism (1) shown in FIG.

The liquid supply mechanism (1) shown in FIG. 10 mainly includes a reservoir (2) and a liquid receiver (3). In the example shown in FIG. 10, the reservoir (2) is arranged on the right side. Similarly to the second embodiment, the reservoir (2) is connected to the liquid receiver (3) with the opening facing downward, and supplies the liquid into the liquid receiver (3).
The liquid receiver (3) has a large opening (34) on its upper surface. Adjacent to the opening (34), an upper plate (35) covering the upper surface of the liquid receiver (3) is provided. A cylindrical supply port (32) is erected upward from the upper plate (35). The upper plate (35) and the supply port (32) support the reservoir (2).
Moreover, the area | region of an opening part (34) is comprised from the edge part (312) standingly arranged from the bottom face (311) and the bottom face (311) outer edge.

A part of the wall surface constituting the supply port (32) extends to the inner bottom surface of the accommodating portion (31) and is connected to the inner bottom surface. The wall surface functions as a support wall (53) that supports the connection mechanism (5).
The support wall (53) is provided with a rotating shaft (531), and a rod-shaped arm portion (54) is connected to the rotating shaft (531). The arm part (54) can be rotated up and down around the rotation axis (531).
A floating body (55) is attached to the end of the arm portion (54) in the region of the opening (34). The floating body (55) has a lower specific gravity than the liquid used. At the other end of the arm portion (54), a rod-like projection portion (52) standing up is disposed.
The upper end of the protrusion (52) is inserted into the pipe (42) of the adapter (4) attached to the reservoir (2), and the valve body (51) arranged in the pipe (42) In accordance with the operation of the part (54), the pipe (42) is moved up and down.

In the liquid supply mechanism (1) having the above configuration, the valve body (51) is the liquid outlet of the reservoir (2) until the reservoir (2) is inserted into the supply port (32) of the receiver (3). To prevent leakage of liquid. When the reservoir (2) is inserted into the supply port (32) and the protrusion (52) pushes up the valve body (51), the liquid from the reservoir (2) passes through the conduit (42) of the adapter portion (4). And then flows down into the liquid receiver (3). The position of the floating body (55) rises while the upper end position of the protrusion (52) falls as the liquid level in the accommodating part (31) of the liquid receiver (3) rises. And the valve body (51) reaches the adapter part (4) lower end, and stops the liquid supply from the reservoir (2).
The pet can ingest the liquid in the container (31) through the opening (34) provided on the upper surface of the container (31). When the liquid level in the container (31) is lowered due to liquid intake, the tip of the protrusion (52) rises again, pushes up the valve body (51), and causes the liquid in the reservoir (2) to flow down. In this way, the liquid level in the storage part (31) is kept in a certain range.
In addition, it is preferable to distribute | arrange the lower end of an adapter part (4) in the position higher than the upper limit of the control liquid level which fluctuates. If it does in this way, since an adapter part (4) will leave | separate from a liquid level, it will become possible to prevent the liquid in a accommodating part (31) flowing backward into a reservoir | reserver (2).
In addition, in the form used as a water supply device for pets, the floating body (55) is not an essential configuration, and a form in which the protrusion (52) protrudes upward from the bottom surface of the housing part (31) may be adopted. Good.

FIG. 11 shows a modification of the liquid supply mechanism (1) shown in FIG. FIG. 11A is a side sectional view of the liquid supply mechanism (1), and FIG. 11B is a view of the liquid supply mechanism (1) as viewed from above.

The wave preventing wall (56) is a U-shaped wall, and both ends thereof extend from the support wall (53). Further, the upper edge of the wave barrier (56) is higher than the liquid level to be controlled. In addition, a flow hole is appropriately provided in the lower part of the wave barrier (56) so that the liquid from the reservoir (2) can flow.
A floating body (55) is disposed in a region surrounded by the wave preventing wall (56) and the support wall (53).
Since the wave barrier (56) surrounds the floating body (55) in this way, the floating body (55) is not affected by the waves generated when the pet ingests the liquid, and the liquid from the reservoir (2) is not affected. Supply will be carried out smoothly.

  As another modification, the floating body (55) may be movable along the arm portion (54) and fixed at a desired position on the arm portion (54). In this way, it is possible to adjust the liquid level control characteristics to be desired. For example, if the floating body (55) is attached to the tip of the arm part (54) arranged far from the reservoir (2), the vertical movement of the valve body (51) becomes gradual, and the vicinity of the reservoir (2) If the floating body (55) is fixed in the middle of the arm portion (54), the valve body (51) can be operated quickly.

In the above example, the adapter portion (4) and the spherical valve body (51) formed in a tapered tube shape have been described, but the adapter portion (4) and the valve body (51) of other shapes are also used. It can be used.

When the lower head (511b) comes into contact with the lower end of the pipe (42), the valve body (51) is in the upper position (see FIG. 12 (a)), and the upper head (511a) is in the pipe. (42) When contacting the lower end, the valve body (51) is in the lower position (see FIG. 12B).

The inside of the valve body body part (512) is formed hollow. An upper opening (513) is formed on the upper peripheral surface of the valve body body (512), and a lower opening (514) is formed on the lower peripheral surface of the valve body body (512), and the upper opening (513) and The lower opening (514) communicates with a hollow portion (516) inside the valve body body.
When the valve body (51) is in the upper position, the upper opening (513) is located above the upper end of the pipe (42), and liquid is supplied into the valve body (51) through the upper opening (513). Is done. On the other hand, the lower opening (514) contacts the inner wall surface of the pipe (42), and the liquid supplied to the inside of the valve body (51) does not flow out of the valve body (51).
When the valve body (51) is in the lower position, the upper opening (513) comes into contact with the inner wall surface of the pipe line (42), and the liquid inflow into the valve body (51) is stopped. On the other hand, the lower opening (514) appears below the pipe (42), and allows the liquid flowing into the valve body (51) to be discharged. The discharged liquid is supplied into the storage part (31).

12B shows a valve body having an I-shaped cross section instead of the upper opening (513), the lower opening (514) and the hollow portion (516) of the valve body (51) of FIG. 12 (a). (51) It is the form which formed the groove part (515) in the valve body trunk | drum (512) peripheral surface. The groove (515) extends along the axial direction of the valve body (512), and when the valve body is in the upper position, the upper end of the groove (515) appears above the pipe (42) and the lower end of the groove (515). Is in contact with the inner wall surface of the pipe (42). The liquid in the reservoir (2) then flows into the groove (515).
When the valve body (51) is in the lower position, the upper end of the groove (515) contacts the inner wall surface of the pipe (42). On the other hand, the lower end of the groove (515) appears below the pipe (42). At this time, the liquid in the groove (515) is discharged.
By using the valve body as shown in FIG. 12, it becomes possible to supply a constant and small amount of liquid to the storage portion (31), and finer liquid level adjustment is possible.
In the groove portion (515), the head portion (511b) disposed at the lower end of the valve body body portion (512) may be removed, and the valve body body portion (512) may be formed in a substantially T-shaped cross section. Then, by extending the groove (515) to the lower end of the valve body (512), when the upper end of the groove (515) appears inside the reservoir (2), liquid continues to flow out from the lower end of the groove (515). It becomes.
