Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a multi-channel detection high-precision water immersion sensor. Background Art

[0002] The water sensor is a device that uses the principle of liquid conductivity to detect whether there is water leakage. Under normal circumstances, the two-pole probe is insulated by air. When immersed in water, the two-pole probe is connected, and the sensor generates an alarm signal to inform the user that there is a water leak in the installation area.

[0003] Patent "CN201922301483.X" proposes a host housing, a detection chip and a connection probe group, wherein the detection chip is arranged in the host housing, a first detection circuit is arranged on the detection chip, the connection probe group is connected to the first detection circuit, and the connection probe group is exposed from the bottom surface of the host housing. The host, the detection end and the connection line in the patent are all integrated and cannot be disassembled, so that if other probes or the host are to be replaced in the patent, a new instrument needs to be replaced, resulting in a large waste of resources;

[0004] To this end, we propose a multi-channel detection high-precision water immersion sensor. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a multi-channel detection high-precision water immersion sensor, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0007] When the staff needs to replace wires of different lengths or replace a new probe end, the staff first slides the slider in the locking assembly so that the slider does not contact the connection end, and then pulls the connection end outward, thereby separating the connection end from the lower end of the control panel. It is installed anyway, and the locking assembly makes it convenient for the staff to disassemble and replace wires of different lengths or replace new probe ends, thereby saving costs.

[0008] As a preferred technical solution of the present invention, the locking assembly includes a slider symmetrically slidably arranged at the lower end of the control panel, the outer wall of the control panel is provided with a sliding groove used in conjunction with the slider, a limit plate is hingedly arranged in the sliding groove, and torsion springs used in conjunction with the control panel are respectively arranged at both ends of the limit plate.

[0009] The slider is clamped by the limit plate, and torsion springs are provided at both ends of the limit plate, so the limit plate will not open at will, preventing the slider from sliding and causing the connection end to fall off.

[0010] As a preferred technical solution of the utility model, the connecting end includes an extrusion block connected to the wire, a connecting column is fixedly provided at the middle position of the extrusion block, and a sealing gasket is pasted on the surface of the extrusion block.

[0011] A sealing gasket is provided at the position where the extrusion block contacts the control panel, thereby preventing water stains from entering and causing the two connecting columns to be connected, thereby causing misjudgment of the instrument.

[0012] As a preferred technical solution of the utility model, inclined surfaces for cooperating with a slider are respectively provided on both sides of the extrusion block, the cross-section of the slider is concave, grooves are respectively provided on both sides of the concave surface of the slider, and an inclined surface for cooperating with the extrusion block is provided at one end of the slider close to the extrusion block.

[0013] By providing inclined surfaces for use with the slider on both sides of the extrusion block, it is convenient for the slider to approach the control panel, thereby pressing the connection end tightly to prevent water from entering between the extrusion block and the control panel.

[0014] As a preferred technical solution of the utility model, both ends of the slide groove penetrate the surface of the control panel, and limit blocks are respectively arranged at both ends of the slide groove.

[0015] Since both ends of the slide groove pass through the surface of the control panel, when the slider is damaged, the limit block is opened and a new slider can be replaced.

[0017] 1. According to the utility model, when the staff needs to replace the wires of different lengths or replace the new probe ends, the staff first slides the slider in the locking assembly so that the slider does not contact the connection end, and then pulls out the connection end, thereby separating the connection end from the lower end of the control panel. It is installed anyway, and the locking assembly makes it convenient for the staff to disassemble and replace the wires of different lengths or replace the new probe ends, thereby saving costs.
