Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a liquid level indicator that informs a liquid level position in a liquid tank with a buzzer.

(B) Conventional Technology In the conventional liquid level indicator, a method of using an electrode rod or a float and operating a switch according to the position of the float to sound a buzzer has been adopted. However, in both cases, the position of the liquid surface inside the liquid tank must be strictly selected and installed, and when installing it, a clasp or adhesive must be used, which was very troublesome. .

(C) Problems to be solved by the present invention The present invention solves the above-mentioned drawbacks and provides a liquid level indicator that accurately informs the liquid level position in the liquid tank by simply putting it in the liquid tank. The purpose is to do.

(D) Means for Solving the Problems First Embodiment FIG. 1 is a sectional view showing a first embodiment of the present invention. The float body (1) is a container (4) and a container (4). It is composed of a lid (5) which is fitted in close contact so that it can be removed and is freely waterproofed. A mounting plate (6) is attached to the inside of the container (4), and a power battery (7) is attached to the mounting plate (6). ), The buzzer (9), and the current amplification circuit (10) are attached so that the vicinity of the bottom of the floating body (1) becomes the center of gravity. A pair of sensors (8) exposed to the outside are attached to the top of the lid (5) so as to be waterproof, and the built-in parts of the sensor (8) and the container body (1) are the technology of Shuchi. Wiring is performed around the current amplification circuit (10) as indicated by the broken line. Further, although the outer upper part of the float body (1) and the weight (3) are connected by the liquid height setting action string (2), the weight (3)
The weight of the float body (1) suspends the weight (3) at the time when the liquid height reaches the position of the liquid height setting action string (2). At this time, the upper part of the float body (1) is It is sufficient that the float (1) is pulled in the direction of the weight (3) so that the bottom of the float body (1) is on the upper side.

Second Embodiment Although there is no drawing for the second embodiment, the current amplification circuit (10) is further provided by separating the floating body (1) from the buzzer (9) which is a built-in component of the floating body (1). From the float to the buzzer (9) to the outside of the float body (1), connect the wire to the footer (9), and set the footer part at an appropriate place depending on the length of the wire. is there.

Third Embodiment Although there is no drawing for the third embodiment, the buzzer (9) is taken out from the first embodiment and placed separately, and instead, a wireless transmission device is built in, and the wireless transmission device is installed in the separately placed buzzer part. Is provided so that the buzzer can be carried around freely.

Fourth Embodiment Although there is no drawing as the fourth embodiment, a light bulb is attached to the outside of the float body (1) of the first, second and third embodiments, and the liquid level position is not limited to the buzzer. It is designed to be visually perceptible.

The present invention has the above configuration.

(E) Action In this method, the liquid height setting action string (2) is tied midway, and its length is adjusted to the desired liquid surface position in the liquid tank (11), and the float is lifted as shown in FIG. The child body (1), the liquid height setting action string (2) and the weight (3) are put in the liquid tank (11). Liquid height setting action string (2) in which liquid is accumulated and set in the liquid tank (11)
As shown in FIG. 3, the liquid level setting action string (2) is stretched by the buoyancy of the float body (1) and the weight of the weight (3) in the opposite direction, and the liquid level Since the setting string (2) is connected to the outer upper part of the floating body (1), the upper part of the floating body (1) is pulled in the direction of the weight (3), and the floating body (1) rotates. To do. At this time, the liquid in the liquid tank (11) comes into contact with the sensor (8) that is exposed and attached to the outside of the floating body (1), and a small current flows through the pair of sensors (8).
The current is amplified by the current amplifying circuit (10), a current flows through the buzzer (9), and the buzzer (9) sounds to inform the liquid surface position.

(F) Effect of the Invention According to the present invention, it is possible to easily know the desired liquid surface position simply by putting it in the liquid tank without using a special installation method in the liquid tank. It is possible to provide an inexpensive liquid level indicator having a smaller number of parts, a simple structure, and a lower price than those of the above.
