Abstract

[0002] A liquid level sensor (static pressure level gauge, liquid level transmitter, liquid level sensor, water level sensor) is a pressure sensor that measures the liquid level. The static pressure submersible liquid level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It adopts advanced foreign isolated diffused silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert static pressure into an electrical signal, and then converts it into a standard electrical signal after temperature compensation and linear correction.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0038] Please see Figure 1-5 A methanol fuel level sensor includes a housing component 100 and a level detection component 200. The housing component 100 includes a fuel tank body 110, and a communicating vessel assembly 120 is provided at one end of the fuel tank body 110. The level detection component 200 is disposed inside the communicating vessel assembly 120. The level detection component 200 includes a sensor assembly 210 disposed inside the communicating vessel assembly 120. A physical level assembly 220 is disposed outside the communicating vessel assembly 120, and the physical level assembly 220 and the sensor assembly 210 are adapted to each other.
[0039] By setting up the sensor assembly 210, the sensor can move inside the communicating vessel assembly 120. By setting up the physical liquid level assembly 220, it can work with the sensor assembly 210 to realize a physical liquid level observation and measurement structure. This structure can determine the remaining fuel in the tank when the sensor fails or is damaged, thus improving its practicality.
[0040] The communicating vessel assembly 120 includes a communicating vessel tube 121 fixedly connected to one end of the oil tank body 110 and communicating with the inside of the oil tank body 110. A tube cap 122 is provided at the top of the communicating vessel tube 121. The sensor assembly 210 includes a sensor body 211 disposed inside the communicating vessel tube 121. A protrusion 212 is provided on the sensor body 211. A first magnetic block 213 is fixedly connected to one end of the protrusion 212. The sensor assembly 210 includes a first convex block 214 fixedly connected to the inner wall of the communicating vessel tube 121. A first convex groove 215 is opened on the inner side of the first convex block 214. The protrusion 212 and the first magnetic block 213 are slidably engaged inside the first convex groove 215, and the first magnetic block 213 is in contact with the inner wall of the communicating vessel tube 121.
[0041] When the first magnetic block 213 slides inside the first convex groove 215, the first magnetic block 213 will drive the sensor body 211 to move inside the communicating tube 121 through the protrusion 212, thereby adjusting the position of the sensor body 211 so that the sensor body 211 can physically contact the fuel liquid surface inside the communicating tube 121, thereby facilitating the determination of the height of the fuel liquid surface inside the communicating tube 121.
[0042] The physical liquid level assembly 220 includes a second convex block 221 fixedly connected to the surface of the communicating vessel tube 121. The interior of the second convex block 221 is provided with a second convex groove 222. A second magnetic block 223 is slidably engaged with the inner side of the second convex groove 222. One end of the second magnetic block 223 is fixedly connected to an extension block 224, and the extension block 224 extends to the outside of the second convex groove 222. The second magnetic block 223 abuts against the surface of the communicating vessel tube 121. The second magnetic block 223 and the first magnetic block 213 are magnetically connected through the communicating vessel tube 121. The communicating vessel assembly 120 also includes a filter screen 123 disposed at the bottom of the inner side of the communicating vessel tube 121.
[0043] By pushing the extension block 224 to slide inside the second convex groove 222, the second magnetic block 223 can be driven to slide inside the second convex groove 222. When the second magnetic block 223 and the first magnetic block 213 are magnetically connected through the communicating vessel tube 121, the movement of the extension block 224 will drive the first magnetic block 213 to move through the second magnetic block 223, thereby driving the sensor body 211 to move inside the communicating vessel tube 121. This facilitates contact with the liquid surface of the fuel inside the communicating vessel tube 121. When the sensor body 211 contacts the liquid surface, buoyancy will be generated, causing resistance to the movement of the first magnetic block 213. Therefore, the height of the liquid surface inside the communicating vessel tube 121 can be determined. Thus, the height of the liquid surface inside the fuel tank can be determined according to the principle of communicating vessels, thereby determining the remaining fuel in the fuel tank.
[0044] The implementation principle of this application embodiment is as follows: When the sensor body 211 malfunctions or is damaged, the extension block 224 and the second magnetic block 223 can be slidably engaged with the inner side of the second convex groove 222. Then, the extension block 224 is manually moved to slide inside the second convex groove 222. The movement of the extension block 224 will cause the second magnetic block 223 to slide inside the second convex groove 222. Since the second magnetic block 223 is magnetically connected to the first magnetic block 213, the movement of the second magnetic block 223 will cause the first magnetic block 213 to slide inside the first convex groove 215. The movement of the first magnetic block 213 will cause the protrusion 212 to slide inside the first convex groove 215. The movement of the protrusion 212 will cause... The sensor body 211 moves inside the communicating vessel tube 121. When the sensor body 211 comes into contact with the fuel level in the tank, the liquid fuel gives the sensor body 211 a buoyancy force. Therefore, the user can feel that the movement of the first magnetic block 213 and the second magnetic block 223 increases the resistance, which makes it easier for the user to determine the height of the liquid level. Then, according to the principle of communicating vessels, it can be known that the height of the liquid level in the tank is the same as the height of the liquid level in the communicating vessel tube 121, thus determining the remaining fuel in the tank. This structure has a physical liquid level observation and measurement structure, which can determine the remaining fuel in the tank when the sensor body 211 malfunctions or is damaged, thus improving its practicality.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
