Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a soil moisture concentration notification plate, and more particularly, to a plate that detects soil moisture concentration and visually notifies the soil moisture concentration.

[0002]

[Prior art]

 For horticultural farmers and horticultural enthusiasts, knowing the exact water concentration in the soil is very important in growing plants. In particular, recently, due to the gardening boom, it has become increasingly popular to plant a variety of plants in flowerpots, and it is becoming increasingly important to accurately know the moisture concentration in the soil.

[0003] That is, when a variety of plants are planted in a single flower pot, there are various things to be noted, but one of them is an important precaution to properly maintain the soil moisture concentration. . It is necessary to accurately detect the current moisture concentration in order to maintain the soil moisture concentration appropriately. As a device for detecting the moisture concentration in soil, there is a moisture meter. However, a full-fledged moisture meter is expensive and the operation is complicated, so it is not suitable for general horticultural farmers and gardening enthusiasts.

[0004] Therefore, as a means for allowing a general horticultural farmer or horticultural enthusiast to easily know the moisture concentration in the soil, a simple water sensor using a moisture sensitive agent as shown in FIG. Has come to be used.

The simple water sensor 61 includes a support body 62, an adhesive layer 63, a water absorbing paper 64, a display layer 65, a water reaction layer 66, a transparent protective film 67, and the like, which constitute a main body of the simple water sensor 61. It consists of.

The conventional simple moisture sensor 61 configured as described above displays the water-absorbing paper 64 sucking up moisture in the soil, and the absorbed moisture gives a change to the water reaction layer 66 to display. It is.

[0007]

[Problems to be solved by the invention]

 The simple moisture sensor 61 is provided with a transparent protective film on the surface of the detection body in order to protect the water absorbing paper 64 and the water reaction layer 66 and to protect the simple water sensor 61 from water supply to plants and rainwater. 67 are arranged. For this reason, the moisture absorbed in the water absorbing paper 64 is hardly removed from the inside of the central region, regardless of the end portion, due to the influence of the transparent protective film 67, and there is a defect that the water remains in the water absorbing paper 64 forever. .

There is a problem that a detection error occurs or recovery of the detection function is delayed due to the water remaining in the water absorbing paper 64. Further, this causes small water droplets to be generated in the transparent protective film 67. Causes of the above-mentioned water droplets becoming cloudy, or the adhesive (not shown) between the water-absorbing paper 64 and the transparent protective film 67 being wetted by the moisture and becoming milky cloudy, thereby shortening the product life. It has become.

[0009] Therefore, conventionally, there is a limit in increasing the surface area of the detection object, that is, the width for enlarging the central portion, and there is a limit in a method of displaying the detected information. There was a problem that could not be done. The present invention has been made in view of the above-described problems, and has as its object to provide a moisture concentration notification plate having a large detection display area and capable of visually displaying the state of soil moisture.

[0010]

[Means for Solving the Problems]

 The soil moisture concentration notification plate of the present invention includes a support 2 constituting a main body of the notification plate 1, a water absorbing layer 4 provided on the support 2, and a water absorbing layer 4 provided on the water absorbing layer 4. And a water reaction layer 6 disposed on the display layer 5. The display layer 5 has a first pattern for notifying that the moisture state in the soil is low. The water reaction layer 6 is non-transparent when the water absorbing layer 4 does not absorb water from the soil, and the water absorbing layer 4 absorbs water from the soil. The first pattern is formed when the water-reactive layer 6 is not transparent because the water-absorbing layer 4 does not absorb water from the soil. The patterns other than the first pattern are formed so that they can be recognized from the outside, and the water absorbing layer 4 When the water reaction layer 6 is transparent, the water reaction layer 6 is formed so as to be recognizable from outside by absorbing water. It is characterized in that the pictures displayed on the layer 5 are sequentially visible from the outside. Another feature of the present invention is that the water reaction layer 6 is hollowed out in a predetermined shape so that the background of the display layer 5 looks like a predetermined shape. By forming one pattern, the first pattern can be recognized from the outside only when the water reaction layer 6 is non-transparent. Another feature of the present invention is that the water absorbing layer 4 is disposed on the support 2 via the adhesive layer 3. . Another feature of the soil moisture concentration notification plate of the present invention is that, in addition to the first pattern that indicates that the soil moisture condition is low, the soil moisture content is slightly low. , And a third pattern notifying that the soil moisture is sufficient is marked on the display layer 5.

[0011]

[Embodiment of the invention]

 Next, with reference to the accompanying drawings, an embodiment of the soil moisture concentration notification plate of the present invention will be described in detail. FIG. 1 is a plan view of a notification plate 1 showing an embodiment of the present invention, and FIG. 2 is a cross-sectional view. As shown in FIG. 1, the notification plate 1 of the present embodiment has a rectangular shape in plan view.

[0013] Then, one end in the longitudinal direction is formed in a sharp tapered shape to form an insertion portion 1a, and the other end is a plate for detecting a moisture concentration. "Water Sensor" is written in English.

[0013] The insertion portion 1a is formed so that the notification plate 1 can be easily inserted into the soil. In the present embodiment, the notification plate 1 is formed of a hard synthetic resin or synthetic paper. It is made of thin wood, thin metal and the like, and the insertion portion 1a is formed so that it can be easily inserted into soil such as a flowerpot.

The notification plate 1 is provided with a support 2 constituting a main body, a water-absorbing layer 4 attached to the support 2 via an adhesive layer 3, and provided on the water-absorbing layer 4. It comprises a display layer 5 and a water reaction layer 6 provided on the display layer 5.

As will be described in detail later, the display layer 5 has a first pattern that reports that the soil moisture state is low, a second pattern that reports that the soil moisture level is slightly low, It is for displaying a third pattern or the like that informs that the moisture in the soil is sufficient. FIG. 1 shows a state in which a character "Empty", which is a first pattern for notifying that the soil water content is low, and a "pattern giving water to Futaba" are displayed. .

As shown in FIG. 2, such a display is a portion corresponding to the above-mentioned “Empty” in the water reaction layer 6 when the water absorbing layer 4 does not absorb water. Only the first display portion 6a and the second display portion 6b, which is a portion corresponding to the "pattern providing water to Futaba", are hollowed out to be transparent, and the other display portions are non-transparent. It is possible by doing so.

The method of making the first display portion 6a and the second display portion 6b transparent when the water-absorbing layer 4 does not absorb water is not limited to hollowing out, and the portions are always made transparent. This can also be realized by:

In the notification plate 1 of the present embodiment configured as described above, when the insertion portion 1a is inserted into the soil such as a flower pot, if the soil has moisture, the water absorbing layer 4 is placed in the soil. Absorbs water.

The water absorbed by the water absorbing layer 4 penetrates into the water reaction layer 6 via the display layer 5, and the water reaction layer 6 becomes transparent. That is, the water reaction layer 6 changes to be transparent up to the position where the water absorption layer 4 is absorbing moisture.

Accordingly, the water in the first display area A in which the first display of the character “Empty” as the first pattern and the “pattern giving water to Futaba” is performed. The reaction layer 6 first becomes transparent.

Therefore, if there is a certain amount of moisture in the soil, the entire first display area A in which the first display is performed becomes visible from the outside, and as shown in FIG. In the first display area A, the letters “Empty” and the “pattern giving water to Futaba” disappeared in the background of the water reaction layer 6. For example, only blue single color display is performed.

As the water absorption of the water absorbing layer 4 progresses, the transparent part of the water reaction layer 6 rises. When the second display area B of the water reaction layer 6 becomes transparent, the second picture drawn in the second display area B becomes visible from the outside as shown in FIG. In the present embodiment, an example in which English characters of "Semi" and a pattern of "sun / watering" are drawn in the second display area B is shown.

As the water absorption of the water-absorbing layer 4 further proceeds, the transparent portion of the water-reactive layer 6 spreads further upward, and the third display area C of the water-reactive layer 6 becomes transparent. As a result, as shown in FIG. 5, the third picture drawn in the third display area C also becomes visible from the outside. In the present embodiment, an example in which English characters of “Full” and a picture of “sun” are drawn in the third display area C is shown.

The user can see that the soil has sufficient moisture by seeing the English characters of “Full” and the picture of “Sun”. Therefore, it can be determined that there is no need to supply water when these indications are displayed.

Since the notification plate 1 of the present embodiment is configured as described above, the inconvenience caused by disposing the transparent protective film 67 on the surface of the detection body, which is a disadvantage of the conventional simple moisture sensor 61, is provided. That is, the water absorbed into the water-absorbing paper 64 is less likely to escape from the inside due to the influence of the transparent protective film 67, so that a defect caused by remaining in the water-absorbing paper 64 forever can be prevented.

Therefore, according to the soil moisture concentration notification plate of the present embodiment, there is a problem that the detection error occurs or the recovery of the detection function is delayed due to the moisture remaining in the water absorption layer 4. Can be prevented.

Furthermore, it is possible to prevent a problem that the adhesive is moistened by the water remaining in the transparent protective film 67 and the milk becomes cloudy, thereby shortening the product life. This makes it possible to increase the surface area of the detection object and improve the performance of displaying the detected information.

In the present embodiment, an example in which the display area is divided into three areas A to C has been described, but the display area may be divided into two or more than three areas. In addition, the display for notifying the state of water in the soil is not limited to the above-described embodiment, and it goes without saying that various characters and patterns can be drawn.

[0029]

[Effect of the invention]

 As described above, the present invention provides a support constituting the main body of the notification plate, a water-absorbing layer provided on the support, a display layer provided on the water-absorbing layer, and a display layer provided on the water-absorbing layer. The first pattern can be seen from the outside only when the water reaction layer is opaque because the water absorption layer does not absorb water from the soil. When the water-reactive layer is transparent because the water-absorbing layer absorbs water from the soil, a pattern other than the first pattern is made visible from the outside. According to the state in which the layer is absorbing the moisture in the soil, the pictures displayed on the display layer can be sequentially seen from the outside. This makes it possible to provide a moisture concentration notification plate capable of visually displaying the state of moisture in the soil. Furthermore, since there is no transparent protective film on the surface, there is no water trapped in the central area of the surface, so that the width of the entire detection object can be increased, and the area of the detection display can be increased, and it can be freely adjusted. Visual display is possible.
