【Example】

An embodiment embodying the present invention will be described below with reference to the drawings.

[0007] The case 1, which is integrally molded from resin, has a pot part 2 that is recessed from the top surface. , and has a water supply tank part 3 of a sealed structure arranged at the lower part of the pot part 2. pot A water pipe 4 is provided from the bottom of the section 2 toward the lower part of the water tank section 3. Before In the outer peripheral space of the storage pot 2, there is a chargeable container that is curved into a cylindrical shape so as to wrap around the pot 2. The paper battery 5, the control circuit 6, and the outside air communicate with the upper part of the water tank section 3. The solenoid valve 8 to which the exhaust pipe 7 is attached also connects the outside air and the upper part of the water tank section 3. An air pump 10 to which a communicating air pipe 9 is attached, mercury is sealed and electricity is connected above and below the air pump 10. Fall detector 11 provided with contacts, charging terminal 12 for the paper battery 5 are stored in each.

[0008] Inside the water tank section 3, there is a water level sensor 1 that detects "full water" from its upper position. 3.Water level sensor 14 that detects "appropriate water";Water level sensor that detects the need for "replenishment" The position sensor 15 detects the "lower" position slightly above the lower end of the water pipe 4. A water level sensor 16 is provided above the pot part 2 to detect the "upper" level. A sensor 17 is provided. The container 18 is housed in the pot part 2, and the hydroponic culture is carried out in this container. It is used to store gravel for holding plants used for cultivation, and there are several at the bottom. holes 19 are provided. The water level in the water tank section 3 is displayed on the upper end of the case 1. A display section 20 and a switch 21 are arranged integrally, and the water pipe 4 has a A solenoid valve 22 is provided for closing the passage of the water conduit 4. Service The cutting plate 23 makes the water supply tank part 3 a sealed structure, and the water supply pipe 7 and the water supply The tube 9 passes through the partition plate 23. In addition, paper battery 5, control circuit 6, Solenoid valve 8, Air pump 10, Fall detector 11, Charging terminal 12, Water level control The sensors 13 to 17, the display section 20, and the switch 21 are electrically connected.

[0009] In the above configuration, the solenoid valve 8 and the solenoid valve 22 are now controlled by the control circuit 6. Closed, the air pump 10 is in a stopped state, and air cannot pass through it. It has become. In this state, the timer function in the control circuit 6 measures the time. When the predetermined time has elapsed, the control circuit 6 opens the solenoid valve 22 and The air pump 10 is operated to send air into the water tank section 3. The surface of the water is pressed down by air pressure. Therefore, water passes through the water conduit 4 to the pot part 2 and Water is supplied into the container 18 until it reaches the upper water level sensor 17.

0010 Thereafter, the control circuit 6 stops the operation of the air pump 10 and turns the solenoid valve 8 into place. After being opened for a certain period of time, the solenoid valve 8 and solenoid valve 22 are closed. This movement As a result, air is discharged from the water tank section 3 via the solenoid valve 8, and water is supplied. The water in the pot part 2 flows back into the tank part 3 and returns to its initial state. This series of actions The plants in the pot part 2 are watered. Watering through this series of operations is carried out by the control circuit 6. This is performed every predetermined time, for example, once a day. The control circuit 6 also includes a water level sensor. -13 to 15 monitor the amount of water in the water tank 3, and the user presses the switch. It is designed to be displayed on the display section 20 only when 21 is pressed, and the user can , whether the water in the water tank section 3 is in a "full" state, "adequate water" state, or " You can know whether "replenishment water" is required and reduce the consumption of paper battery 5. It is kept to a minimum. The control circuit 6 also operates when the switch 21 is pressed. A drive command is issued to perform the water supply and drainage operations at the same time, and the user can perform the water supply and drainage operations when necessary. It can be made to perform an action.

[0011] Incidentally, the "lower" water level sensor 16 is connected to the water level sensor 16 in the water supply tank section 3 during the water supply operation. When the water moves into the pot 2 and the amount of water no longer reaches the water level sensor 16, the air pump 10 stops, i.e. the state equivalent to reaching the "upper" water level synthesizer 17. This prevents the air pump 10 from sending air into the water pipe 4.

0012 Here, if this pot falls over, the fall detector 11 is tilted and placed above and below it. The mercury enclosed in the electrical contacts short-circuits, and the control circuit 6 detects the signal and outputs the solenoid. Close the noid valve 22. Therefore, the water in the water tank section 3 is transferred to the air pump 1. In the non-operating state of 0, even if the pot falls over, it will not overflow to the outside, and the operating time will be reduced. It is generally extremely short compared to the flying time.

[0013] In this embodiment, the solenoid valve 8 was closed when not in operation, but the water supply tank Part 3 should have a sealed structure, and the exhaust pipe 7 should be for air, so the pipe diameter should be small. Therefore, if the solenoid valve 22 is closed, the exhaust pipe 7 will be removed when the pot falls over. The amount of water leaking can be reduced for practical use. It also detects overturning of pots. In this embodiment, a fall detector 12 is provided in order to prevent the fall of a pot from falling inside the water pipe 4. A mechanical mechanism may be provided to block the water conduit 4 at this time.
