[0029] In the prior art, the magnet is set in the float, which occupies the space inside the float filled with lightweight objects, resulting in the float being too large and inconvenient to use. In addition, in the existing magnetic float level gauge, the sensor is set in the box body, and the box body is connected to the fixing part by threads, which requires high processing accuracy. Moreover, different fixing parts have different threaded holes with different specifications, which requires different molds to be designed, resulting in high processing costs. In addition, there is a risk of thread slippage and other risks in the long-term use of threaded connections, which poses a quality risk.
[0030] To solve the above problems, this embodiment provides a liquid level detection device. Figure 1-Figure 3 , including a fixing part 10, a box body 20, a floating component 30 and a magnetizing component 40; the box body 20 extends along a first direction and is integrally formed with the fixing part 10, and a sensor is arranged inside the box body 20; the floating component 30 is sleeved outside the box body 20 and can slide along the first direction as the water level changes; the magnetizing component 40 is sleeved outside the floating component 30 and can slide with the floating component 30 to selectively connect the sensor. The magnetizing component 40 is sleeved on the floating component 30 to avoid occupying the internal space of the float 31 and increase the convenience of use; the box body 20 and the fixing part 10 are integrally formed, which reduces the processing cost and avoids quality risks.
[0031] Specifically, the case body 20 is made of a resin material.
[0032] Furthermore, the floating assembly 30 includes a float 31 and a sliding block 32. The sliding block 32 is sleeved outside the box body 20. The float 31 is arranged at one end of the sliding block 32 away from the box body 20. The float 31 can drive the sliding block 32 to slide along the first direction as the water level changes. In this embodiment, the box body 20 and the sliding block 32 are both configured as bare rods, and the box body 20 and the sliding block 32 are slidably connected with each other through clearance fit. In other implementations, the box body 20 and the sliding block 32 can be connected through a slider slot or a pulley rail.
[0033] Furthermore, a pin hole is provided at one end of the box body 20 near the float 31, and a long hole 321 is provided on the sliding block 32 extending along the first direction, and the pin shaft 21 is inserted into the pin hole and can abut against the inner wall of the long hole 321 to prevent the sliding block 32 from detaching from the box body 20. In other embodiments, a limit rod can also be integrally formed at one end of the box body 20 near the float 31.
[0034] Furthermore, the float 31 is made of polypropylene material, and a foam material is enclosed in the float 31. The foam material can provide buoyancy for the float 31, so that the float 31 can float with the change of liquid level, and the polypropylene can prevent the measured liquid from soaking the foam material and thus damaging the buoyancy of the float 31.
[0035] Furthermore, two first clamping blocks are arranged at intervals along the first direction at the end of the sliding block 32, and the two first clamping blocks are respectively abutted against the two ends of the float 31 to connect the float 31 and the sliding block 32. Specifically, a clamping groove is arranged on one side of the float 31, and a clamping hook is arranged on one of the first clamping blocks, and the clamping hook is hooked with the clamping groove, so that the connection between the float 31 and the sliding block 32 is more stable.
[0036] Furthermore, the magnetization assembly 40 includes a magnet 41 and a magnetic cover 42, and the magnetic cover 42 can abut the magnet 41 against the sliding block 32 along the axial direction of the magnetic cover 42. Specifically, the other end of the sliding block 32 is provided with two second clamping blocks spaced apart along the first direction, and the magnet 41 and the magnetic cover 42 are both provided between the two second clamping blocks to prevent the magnet 41 and the magnetic cover 42 from falling off.
[0037] Furthermore, the sensor includes a reed switch, which is disposed at one end of the box body 20 away from the floating assembly 30. The floating assembly 30 slides in a first direction, and can drive the magnetizing assembly 40 to move in a direction close to or away from the reed switch. When the magnet 41 approaches the reed switch, the reed switch is magnetized, so that the reed switch sends a liquid level signal.
[0038] Furthermore, the liquid level detection device further includes a wire 50, which extends along a first direction and has one end connected to the reed switch for communication. When the reed switch is magnetized, the liquid level signal is transmitted to the host computer through the wire 50. Specifically, the other end of the wire 50 is connected to a terminal 60, and the terminal 60 is provided with a jack for communication with the host computer.
[0039] Further, the fixing member 10 includes a fixing buckle 11, which can be engaged with the connecting rod to fix the fixing member 10. Specifically, a plurality of fixing buckles 11 are arranged at intervals along a certain direction to increase the fixing stability. The spacing direction of the plurality of fixing buckles 11 is not limited here.
[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
