Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1, an automatic coolant filling apparatus includes a high level monitor a, a low level monitor B and a minimum allowable liquid level monitor C sequentially arranged in a filling chamber 100 from top to bottom, in order to facilitate real-time observation of coolant conditions in the filling chamber, the filling chamber 100 is made of a transparent material;

the high-level monitor A, the low-level monitor B and the lowest allowable liquid level monitor C are all connected with the control circuit 200, and the high-level monitor A, the low-level monitor B and the lowest allowable liquid level monitor C are respectively a high-level probe, a bottom-level probe and a lowest allowable liquid level probe;

the control circuit 200 is connected with a water pump 300, the water pump 300 is connected into a cooling liquid barrel 400 through a water suction pipe 301 and is connected into a filling port 101 of a filling cavity 100 through a water outlet pipe 302, and the water outlet pipe is a hose and is good in flexibility and convenient to move and install in the filling port.

As shown in fig. 2, specifically, the control circuit 200 includes a sensor 201, a power supply 202, a relay 203, a transistor 204, a normally open contact J1 and a normally open contact J2, the high water level probe is electrically connected to the sensor pin 1, the lowest allowable liquid level probe is electrically connected to the sensor pin 2, the bottom water level probe is connected to the normally open contact J1 and then connected to the sensor pin 1, the power supply is electrically connected to the transistor and the relay in series and then connected to the sensor pin 3, the transistor is further connected to the sensor pin 4, and the normally open contact J2 is connected to the water pump in series. The control principle is as follows: when the water level drops below the point B of the low-level monitor, the pins 1 and 2 of the sensor are disconnected, the pin 4 of the sensor is at a low level, the triode is conducted, the relay is attracted, the normally open contact J2 is conducted, and the water pump starts to work. When the water level rises to the high-level monitor of A point, because coolant liquid electric conductivity, sensor pin 1, 2 establish ties, create the azithromycin pin 4 and be in the high level, the triode cuts to, and the relay stops the actuation, and normally open contact J2 disconnection, normally closed contact J1 closure resets, and the water pump stop work.
