JPH01242948A - Detector for dewatering soil in pot - Google Patents

Abstract

PURPOSE:To effectively detect the timing of watering and to take advantage of the detection for evading a failure in watering by measuring the rest of water when a water rest sensor part is stuck into the soil in the pot to proper depth. CONSTITUTION:The dewatering detector consists of a thermometer type external case 1, the water rest sensor part 2 incorporated in the tip part of the external case 1, an index display part 3' provided to the rear end part of the external case 1, and a microcomputer 4 which is incorporated in the case 1 so that the water rest sensor part 2 is its input side and the display part is its output side. Then when the water rest sensor part 2 is stuck into the soil in the pot by the proper depth, the water rest sensor part 2 measures the rest of water. The measurement result is displayed on display parts 3 and 3'. Consequently, the timing of watering is detected effectively and utilized to evade the failure in watering.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a soil drainage detector in a potted flower pot, which is used to determine when to water potted plants.

In addition, in the present invention, draining includes a state in which there is little remaining water.

[Conventional technology]

In general, the current situation is that people acquire knowledge and techniques for watering and dispensing potted flowers by reading literature taught by people with experience.

However, even if you acquire the knowledge and techniques as described above, potted flowers often develop root rot due to being given too much water, and wither due to lack of water.

There is an old proverb that says, ``Tsumashi, Mizuyashi, Three Years'' means that even those who are experienced in watering potted plants have had many mistakes and failures.

[Problem to be solved by the invention]

An object of the present invention is to provide a soil drainage detector inside a potted plant, which is extremely effective and convenient for determining the above-mentioned difficult timing of watering, and which is useful for avoiding the above-mentioned failures. That is.

[Means to solve the problem]

In order to achieve the above object, the soil drainage detector in the body of a potted plant according to the present invention includes an outer case shaped like a thermometer, a residual moisture sensor built in the tip of the outer case, and It is equipped with an appropriate display section such as an index display section or a graphic display section provided at the rear end, and a microcomputer built into the outer case that operates with the moisture level sensor section as an input side and the display section as an output side. It is something.

[For production]

The soil drainage detector in the body of a potted plant according to the present invention measures the residual moisture level by the sensor unit when the tip is inserted into the soil inside the body to an appropriate depth in a usable state, and displays it on the display. The detection results are displayed on the screen.

〔Effect of the invention〕

Since the present invention has the above-described configuration, it is possible to easily obtain invisible data in the soil indicating that the remaining moisture content is zero or less, based on the detection results displayed on the display. It is very effective and convenient to use for knowing the timing of water and water, and if the above data and the manual given in advance are used to make water and water, It is possible to significantly reduce the number of failures compared to cases based on experience, and is particularly useful for avoiding failures when people with little experience perform water palms.

〔Example〕

Hereinafter, the first and second embodiments of the present invention will be described.
To explain based on the figures, in the figure (11 is an outer case having the shape of a thermometer made of hard plastic, (2) is a residual moisture sensor part built in the tip of the outer case (1), (3) (3)
' is an index display section and a graphic display section provided at the rear end of the outer case (1), and (4) operates with the moisture level sensor section (2) as the input side and the display section (3) as the output side. When the tip of the microcomputer built into the outer case (1) is inserted into the soil inside the body, the water remaining amount sensor unit (2) measures the amount and displays the display unit (31 (3).
' The detection results are displayed in '.

The remaining moisture sensor part (2) is a self-heating type (indirect heating type).
The structure uses a thermistor that uses a temperature sensing element to detect using the rolling and wet bulb principles of a thermometer.
It is another structure that has the function of achieving the desired effect.

[Brief explanation of the drawing]

FIG. 1 shows the entire oblique restoration of the first embodiment of the present invention, and the second embodiment of the present invention.
The figure is an overall perspective view showing the second embodiment. (1)...outer case, (2)...remaining moisture sensor section, (3)(3)'...display section, (4)...microcomputer.

Claims (1)

[Claims] An outer case shaped like a thermometer, a moisture level sensor built into the tip of the outer case, an appropriate indicator such as an index display or graphic display provided at the rear end of the outer case, and a moisture level sensor built into the tip of the outer case. A soil drainage detector for a potted plant, characterized by having a microcomputer built in an outer case using mercury, which operates with a quantity sensor section as an input side and a display section as an output side.
