3 is a conceptual diagram illustrating a coolant sensing device equipped with a time relay according to the present invention, and FIG. 4 is a view illustrating a coolant container according to the present invention.

As shown in FIG. 3 and FIG. 4, the present invention is connected by a power supply unit 100 and a cooling water 610 to apply power through the power supply unit 100, and when there is no cooling water 610, the power supply unit 100. The coolant 610 is connected to the connection part 200 to cut off the power applied through the power supply, and the power supply is applied through the cooling water 610, the connection part 200 is relayed to the off contact, the cooling water 610 connection part 200 The relay unit 300 is relayed to an on-contact point by the blocking operation of the relay unit 300 for applying power through the power supply unit 100, and the warning unit 500 is operated by receiving power through the relay unit 300. In the cooling water 610 detection device, a time relay 400 is further formed between the relay unit 300 and the warning unit 500, and the coolant 610 is connected by the blocking operation of the connection unit 200. Relayed to an on-contact point to supply power to the warning unit 500 Before or after the time relay, the relay unit 300 is configured to control whether the power is applied to the warning unit 500 in accordance with the time.

Hereinafter, each configuration will be described in detail.

The power supply unit 100 applies electricity to the connection unit 200 and the relay unit 300 to determine whether the warning unit 500 is operated.

Preferably the power supply unit 100 is controlled by the user can be turned on, off.

The connection part 200 is formed of two terminals and is formed on one side of the cooling water container 600, and one terminal thereof is connected to the power supply part 100. Therefore, the connection part 200 is connected to the two terminals by the cooling water 610, the power is supplied, and the connection between the two terminals is blocked without the cooling water 610. That is, when the coolant 610 is in contact with the connection unit 200, the power of the power supply unit 100 is applied to transfer the power to the relay unit 300, which will be described later, and the coolant 610 is not in contact with the connection unit 200. Otherwise, the power of the power supply unit 100 is not applied.

Preferably, the connection part 200 is fixedly installed at a point where the amount of the coolant 610 before the heat generated in the engine cannot be cooled, and is usually before and after a point of 1/3 of the cylinder of the coolant 610. It is good to be installed.

In the relay unit 300, the coolant 610 is connected to the two terminals of the connection unit 200 to be relayed to an off contact by an applied power source so that the power through the power supply unit 100 is cut off, and the coolant 610 is The power applied by the blocking operation of the connecting portion 200 separating the two terminals of the connecting portion 200 is relayed to the on-contact point and transferred to the warning unit 500 described later.

The warning unit 500 receives power from the relay unit 300 to notify the passenger or driver of the bus about the danger.

Preferably, the warning unit 500 receives a power from the relay unit 300 to turn on a lamp to inform the coolant 610 injection time, and a warning light to receive power through the relay unit 300 to receive the cooling water 610 is made of a buzzer for generating a warning sound informing the timing of injection.

Here, the warning light is attached to a position that can be identified by the driver, the buzzer is installed in a plurality inside the bus.

In the present invention, the time relay 400 is installed between the warning unit 500 and the relay unit 300. When the coolant 610 is positioned above the connection part 200 in the coolant container 600, the relay part 300 is off-contacted so that power is not applied to the warning part 500, thereby notifying a danger. When the coolant 610 is positioned below the connection part 200, the relay part 300 is in contact with the power supply to the warning part 500 to inform the user of the danger, and the driver recognizes this and supplies power to the power supply part 100. Operation is possible in the state of being cut off.

However, when the coolant 610 surface of the coolant 610 is formed at the position similar to the contact portion 200 in the coolant container 600, the two terminals of the contact portion 200 are connected and disconnected whenever the vehicle is shaken. The relay unit 300 is powered or not applied to the warning unit 500, so that the warning light and the buzzer to operate and non-operation continuously, passengers and drivers are inconvenient.

As shown in FIG. 4, when the coolant 610 is 'c', the warning unit 500 does not operate, but the coolant 610 becomes 'a' and 'b' whenever the bus moves. 500 is activated and deactivated.

Therefore, since the time relay 400 is installed between the warning unit 500 and the relay unit 300, the warning unit 500 is continuously contacted from the relay unit 300 for a time specified by the user. Make sure the power is applied.

Here, the designated time of the time relay 400 can be specified in various ways according to the user, but usually about 5 seconds.

Figure 5 is a block diagram showing a cooling water detection device equipped with a time relay according to the present invention.

As shown in FIG. 5, the power supply unit 100 supplies power to the connection unit 200. When the connection unit 200 is connected by the coolant 610, the relay unit 300 is turned off. When the power is grounded and the connection unit 200 is not contacted by the coolant 610, the relay unit 300 is in direct contact with the power, and the time relay 400 is also transferred.

In addition, when the on-contact point of the relay unit 300 is 5 seconds or more, the time relay 400 contacts the warning unit 500 by informing the danger, and when it is less than 5 seconds, the off-contact point is grounded. .

As described above, it is a basic technical idea to install the time relay in the coolant detection device, which is merely exemplary, and various modifications and equivalent embodiments may be made by those skilled in the art. As will be appreciated, the true technical protection scope of the present invention should be defined only by the appended claims.
