Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plant watering device that supplies water and culture solution to plants grown in flower pots, planters, and the like.

Conventional plant waterers include those shown in FIGS. 8 and 9.

In the case shown in Fig. 8, (1) Since the tank part 102 of the branch tank 101 is rectangular, it has low water pressure resistance, and a timer and solenoid valve are used to intermittently flow water. If water is intermittently flushed using a water fountain, the tank portion 102 is likely to expand and contract repeatedly and be damaged.

(2) Since the tank joint 103 and the tank connection part 104 are simply connected by a tapered fit, the tank joint 103 easily comes off from the tank connection part 104.

In particular, when tension is applied to the thin tube 105 or water pressure is high, it becomes easy to slip out.

(3) The tube 105 made of thin polyethylene resin with an outer diameter of about 2 wg and the tank joint 103 made of ethylene vinyl acetate resin have similar elastic modulus, and the joining of the two can be achieved by press-fitting using a simple dimensional difference. Therefore, water tends to leak from the joints.

(4) Since the spacing between tank connecting parts 1040 is determined not by the outer diameter of the thin tube 105 but by the outer diameter of the tank joint 103, the tank part 102 can be fitted with a large seat.

Therefore, the tank portion 102 becomes larger than necessary, which causes an increase in cost. Of course, it is susceptible to damage due to expansion and contraction due to intermittent water supply.

There were drawbacks such as.

The one in Fig. 9 includes: (1) A rubber gasket 204 whose curled portion 202 at the tip of the tube 201 prevents water from leaking from inside the tank 203 when a force in the direction of the arrow is applied to the thin tube 201 during use.
It slips out and moves to the position shown by the dashed line, causing water to leak.

(2) Since the nozzle stand 205 is a straight pipe, the actual usage state is as shown in FIG. For this reason, connection hose 2
06, wire clamp 207 attached to it, Y-shape (
Second, many extra piping materials such as 208 are required, and the piping work is troublesome. Water leaks easily because there are many connections.

(3) As a result of the above, the hoses end up coiled around pot shelves and flower buds that should normally be kept tight, resulting in an unsightly appearance.

There were drawbacks such as.

The purpose of the present invention is to improve the above-mentioned drawbacks, have high water pressure resistance,
To provide a watering device for plants that is resistant to water leakage, can be used continuously with simple piping, and has excellent handling properties.

In the present invention, in order to achieve the above object, the cylindrical hose connection part is arranged in a straight line, and the branch tube connection part is provided in a T-shape perpendicular to the cylindrical hose connection part.

In addition, to prevent the end of the branch tube from slipping out of the branch gasket, a branch seat is installed inside the branch gasket.The gasket prevents water from leaking from the outer periphery of the branch tube, and the branch seat prevents the tip of the branch tube from slipping out. We performed functional differentiation.

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 and 3, the main case 1 has a timer 2 and a water supply valve 3. The water supply pulp 3 is operated by a timer 2 and opens and closes the water supply channel.

A hose 4 from a water faucet is connected to the inlet side of the pulp 3 for water supply.
However, hoses 5 to branch tanks 6 are connected to the outlet sides.

A plurality of thin branch tubes 7 are inserted into the branch tank 6, and a nozzle 8 is detachably connected to the tip of the branch tube 7.

As shown in FIG. 2, this nozzle 8 is made of polypropylene,
A flexible elongated cylindrical body 9 made of a synthetic resin material such as polyethylene or vinyl chloride, a large number of ejection holes 10 formed in this cylindrical body 9, and an aluminum wire or the like inserted into the hollow part of the cylindrical body 9. It is composed of a flexible wire 11.

One end of the cylindrical body 9 constituting the nozzle 8 is closed by welding, and an insertion part 13 is formed on the distal end side of this closing part 12. A connector 14 having a water passage hole is provided at the other end of the cylindrical body 9.
is fixed. The branch tube 7 is inserted into the connection port of the connector 14.

When some of the plurality of nozzles 8 are not used, water sprinkling from the nozzles 8 can be stopped by connecting the branch tube 7 to the insertion part 13 of that nozzle 8.

Since the nozzle 8 has the above-described configuration, the water supplied from the hose 4.5 and the branch tube 7 passes through the hollow part of the cylindrical body 9 and the spout hole 10, and is ejected as shown in FIG. It is.

Now, since this nozzle 8 is equipped with a flexible wire 11, it can be bent into various shapes such as a spiral shape and a meandering shape as shown in FIG. 1, and the bent shape can be maintained. .

FIG. 3 shows the nozzle 8 bent into various shapes and placed at the base of a plant 16 grown in a planter 15, or attached to the base or branch of a plant 18 in a flowerpot 17. This is an example of actual use. ' In this way, the nozzle 8 can be arbitrarily bent into various shapes, so it can be adjusted to suit the tension of the roots of the plant 16 and the
7 or the shape of the branches of the plant 18 can be obtained. At the same time, since the nozzle 8 itself maintains its shape, there is no need for a separate holder, making it extremely easy to handle and highly practical.

Next, the branch tank will be explained in detail.

As shown in FIGS. 4 and 6, the branch tank 6 includes a tank body 19, a branch cap 20. Branching patch all 1, branching seat 2
2 and a filter 23. Also,
The tank body 19 has a cylindrical hose connection part 24 and a cylindrical branch tube connection part 26 having a threaded part 25 on the outer periphery.
It's well established.

The cylindrical hose connection part 24 is for connecting an extension hose of arbitrary length, and the hose connection parts 24 form a pair on the left and right, and are arranged in a straight line. Further, a branch tube connecting portion 26 is provided so as to be orthogonal to the pair of hose connecting portions 24 and forming a T-shape.

The tank body 19 is a pressure vessel subject to water pressure, and is preferably made of ABS or polypropylene resin by integral molding in order to reduce costs and ensure mass productivity.

The tank body 19 has a shape similar to a T-shaped joint used for water pipes, etc., and has excellent pressure resistance. Moreover, as shown in FIG. 5, a plurality of branch tanks 6 can be connected in succession to the hose connection portion 24 by using the extension connection hose 27 and the wire clamp 28.

In this embodiment, ten nozzles 8 are connected to one branch tank 6, so 10 nozzles 8 are connected to each branch tank 6.
Can be used to water flower pots, etc.

Note that 5, for example, 10 branch tanks 6 are connected in series,
Connect this to two or three rows using a Y-shaped branch joint, etc.
May be connected in parallel in columns. In this way, 100 pots for 1 row, 200 pots for 2 rows, 30 pots for 3 rows.
It becomes possible to water 0 pots.

Moreover, the piping becomes cleaner.

If they are connected in series as shown in FIG. 5 and the terminals are sealed with rubber caps 29, it is possible to spray water from all the nozzles 8. Moreover, water is supplied from one place,
If the branch tank 6 and the connecting hose 27 are arranged to form a closed loop, water can flow out from all nozzles 8 more uniformly.

The branch gasket 21 is made of rubber or other material with excellent elasticity, and is used to prevent water from leaking to the outside from the hole 30 of the branch cap 20 through the outer periphery of the thin branch tube 7. This branch tube 21 should be made of rubber with a shore hardness of 40 to 60 for ease of insertion of the branch tube 7 (which can be said to be easy to assemble during mass production) and prevention of water leakage. Although it is hard, it can withstand actual use.

The branch seat 22 is the curled end 3 of the branch tube 7.
1 does not easily pass through the branch seat 21. Therefore, the through hole 32 is made slightly thicker than the outer diameter of the branch tube 7.
The material of 1 is a branch tube 7 made of polyethylene resin, etc.
It is necessary to select a material that is somewhat harder and less likely to deform. For example, ABS resin molded products are preferable.

As described above, according to the embodiments of the present invention, (1) the branch tank, which is the main part of the plant watering device, can be made into a T-shaped joint, which is optimal as a pressure-resistant water container; Will not be damaged.

(2) Since the arrangement of the branch tube within the branch cap is determined by the degree of curl at the end of the branch tube, a compact shape can be achieved.

(3) Since branch tanks can be connected in succession, it is easy to dispose of hoses, etc., and the handling is good.

(4) Because the branch seat prevents the branch tube from coming out easily, water leaks are unlikely.

We were able to obtain many effects such as

As described above, according to the present invention, it is possible to provide a watering device for plants that has high water pressure resistance, is resistant to water leakage, and is also easy to handle.
