Description

[Detailed explanation of the invention] (a) Purpose of the invention (industrial application field) This invention enables automatic watering of potted plants in general households, etc., and allows for automatic watering of potted plants when traveling etc. The aim is to eliminate problems such as plants dying due to forgetfulness.

(Prior Art) Conventional automatic water supply machines of this type typically supply water using a pump operated by a motor. In addition, there were also special pots in which a water storage chamber was formed inside the pot, and the water in the chamber was supplied to the roots of the plant.

(Problems to be solved by the invention) The production cost of an automatic water dispenser using a pump operated by a motor as described above is extremely high, and it is extremely difficult to provide it at a low price as a water dispenser for general household use. It was hot.

Furthermore, in the case of a pot equipped with a water supply function as described above, there are various water supply systems, but all of them tend to lead to oversupply of water and root rot.

The present invention eliminates these problems in the past, and can be manufactured at an extremely low cost because it does not use a motor. It also reduces overwatering by supplying water from above the potted plants. This system is characterized by solving the problem of supply and at the same time, by returning surplus water to the water tank, rational use of water is achieved.

(B) Structure of the invention (means for solving problems) The present invention is based on a water tank 1 whose upper opening is used as a surface for placing potted plants, and at the bottom of the tank 1, a water guide hole 3a is bored in the body, and the inner surface thereof is A water supply cylinder 3 with a valve body 3b made of rubber or the like attached thereto is fixedly installed, and a watering nozzle 5 is attached to the upper edge of the water tank 1, and the nozzle 5 and the tip of the water supply cylinder 3 can communicate with each other. This invention relates to an automatic watering machine for potted plants, characterized in that the water supply cylinder 3 is connected to the water supply cylinder 3 and a known compressor 6 that provides intermittent air supply through electromagnetic action is connected in a communicable manner.

(Example) An example of the configuration of the present invention shown in the drawings will be described in detail as follows.

In the figure, 1 is a water storage tank, and a potted plant mounting frame 2 is attached to the upper opening of the tank.

3 is a water supply tube fixed to the bottom of the water storage tank 1, and its body is provided with a water guide hole 3a as shown in FIG. A valve body 3b is attached, and the valve body 3
b is configured to open and take in water when the internal pressure of the water supply cylinder 3 decreases.

Reference numeral 4 denotes a water guide pipe connected to the tip of the water supply cylinder 3 so as to allow communication, and 5 indicates a water nozzle attached to the upper edge of the water tank 1, which directs the water sent through the water pipe 4 to the water tank. This is for sprinkling water on the upper surface of the container. Further, the nozzle is constructed so that its mounting angle and direction can be freely adjusted.

Reference numeral 6 denotes a compressor incorporating a timer mechanism, and the compressor 6 is communicatively connected to the base end of the water supply cylinder 1 through an air guide hose 7. Further, the compressor 6 is
The mechanism is exactly the same as that of commercially available air supply compressors for breeding tropical fish, etc., that is, based on an electromagnetically vibrating operating lever, the air supply body is expanded and contracted to supply compressed air intermittently. Since such a configuration belongs to the known technology, a detailed explanation of the specific configuration of the compressor 6 itself will be omitted. In other words, although it is an essential requirement for the present invention to use a compressor that provides intermittent air supply through electromagnetic action, the specific configuration for this purpose is not that of any known compressor of this type. Also allowed.

6a is a timer dial for setting the energization start time, 6b is a timer dial for setting the energization stop time, and 6c is a energization cord.

By the way, the compressor used in this invention uses an AC power source to perform its electromagnetic action. The intermittent supply of air is determined by the power supply frequency. Therefore, the number of intermittent supplies is 50 or 60 times per second. The air supply pressure is about 1 Kg/cm ² .

Furthermore, the diameter of the water supply cylinder 3 is about twice the diameter of the air guide hose 7, that is, about 2 cm. Further, the size of the valve body 3b is equal to or smaller than the diameter of the water guide hose 7.

In the end, the present invention uses air supplied intermittently at high speed to cause the valve body 3b to perform a vibratory opening/closing action to take water into the water supply cylinder 3, and the taken water to the water guide pipe 3. Based on the force of blowing air inside,
It is constructed so that it is transmitted to the inner wall of the pipe, pushed up, and sprayed from the nozzle 5. Therefore, the present invention is completely different from pumping water sprinkling using a pump, and is configured to perform spray water sprinkling using air.

(Function) As shown in Fig. 4, the present invention places a required number of potted plants on the frame 2 of the water storage tank 1 which has been filled with water in advance, and simultaneously energizes the compressor 5 and sets its timer to the desired time. Set it to the time.

When the desired time comes, the compressor 6 is started by the operation of the timer, and air is sent into the water supply cylinder 3 via the air guide hose 7.

However, since the compressor 5 supplies air by electromagnetic action, the air supply is extremely fast but intermittent, and therefore the internal pressure of the water supply cylinder 3 is Intermittent atmospheric pressure changes occur in conjunction with the intermittent air supply,
When the pressure is low, the valve body 3b is opened and the water guide hole 3a is opened.
When the pressure is high, the valve body 3b
The operation of closing the valve and stopping the suction is repeated rapidly and continuously.

When such an operation is repeated and the required amount of water accumulates in the water supply cylinder 3, the increase in the internal pressure of the water supply cylinder 3 as described above acts as a pressure for sending out the internal water (when the internal pressure decreases, it becomes less than the previous level). Similarly, the internal water is sent to the watering nozzle 5 via the water pipe 4 to water the potted plants.

After the required time has elapsed after the start of water sprinkling, the compressor 5 is stopped by the operation of the timer, and the water supply is stopped.

In addition, FIG. 5 shows water storage tank 1 in which auxiliary water storage tank A has already been described.
This figure shows an example in which the water is connected via a water-conducting communication hose B. In this case, the auxiliary water tank A has no water sprinkling function at all, and water is supplied all at once through the nozzle 5 of the water tank 1. That is, if a powerful compressor 6 is used, implementation in such a form is also possible.

(c) Effects of the invention Since the invention is configured to make it possible to supply water to potted plants using a well-known electromagnetic oscillation compressor, it does not require a pump operated by a motor like conventional water supply machines of this type. The manufacturing cost is significantly lower than that of systems that rely on water, and therefore automatic water dispensers for home use can be provided at low prices.

In addition, since the present invention is configured to water the potted plants from above, the water supply to the plants becomes an extremely ideal form. For example, when water is supplied only to the roots of the plants (planted in the soil). This will effectively avoid problems such as root-rooted outbreaks.

Furthermore, since the present invention is configured such that a potted plant is placed in the upper opening of the water storage tank 1, surplus water (water that does not touch the plants) during watering is drained into the water storage tank 1.
This will contribute significantly to the rational use of water.
