Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) device technology, and in particular to a water immersion sensor that is easy to install. Background Technology

[0002] With the development of IoT technology, smart home systems are increasingly widely used in home security monitoring. Water immersion detection devices, as an important component of smart home systems, are mainly used to monitor for leaks and water accumulation indoors to prevent property damage caused by burst pipes or leaking equipment. Currently, common water immersion detection devices typically consist of a gateway and a water immersion sensor. The gateway receives sensor signals and uploads them to the cloud or local control system, while the water immersion sensor monitors the water immersion status of the ground or a specific area in real time. The water immersion sensor includes a housing, a circuit board inside the housing, and two probes electrically connected to the circuit board. The probes are the core sensing elements of the water immersion sensor. When the probes come into contact with water, the conductivity of the water creates a closed loop between the two electrodes, reducing resistance and allowing current to flow, thereby triggering the sensor to output a switching signal.

[0003] In practical applications, water immersion sensors are typically battery-powered to ensure long-term stable operation without an external power source. However, existing water immersion sensor battery installation methods usually require users to use tools such as coins and screwdrivers to install or replace the battery by rotating or prying open the sensor's back cover. While this design is simple in structure, in actual use, users often need to prepare additional tools, making the operation cumbersome and inefficient. Therefore, this paper proposes a water immersion sensor that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a water immersion sensor that is easy to install, which can effectively solve the aforementioned problems.

[0005] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] The receiving groove is provided with a cover plate assembly, which includes a cover plate body and a fixing post vertically inserted through the cover plate body; the fixing post is threadedly connected to the cover plate body; the cover plate body is provided with a through hole for the probe to pass through;

[0008] In the initial state, the probe presses the cover plate body against the receiving groove; when installed in place, the probe passes through the through hole, and the fixing post presses the battery against the battery holder.

[0009] This utility model discloses a water immersion sensor that is easy to install. The housing of the water immersion sensor includes a base and a detachable top cover located above the base. The base is shaped like a "Z" and the base and top cover together form the inner cavity of the water immersion sensor. A circuit board is provided inside the inner cavity and is located on the upper surface of the base. A waterproof edge is raised on the surface where the base and the top cover are connected.

[0010] This utility model discloses a water immersion sensor that is easy to install. The upper surface of the base is provided with a positioning block, and the battery holder and the positioning block are integrally formed. The upper end of the probe is located in the inner cavity and is soldered to the lower surface of the circuit board.

[0011] This utility model discloses a water immersion sensor that is easy to install. The battery holder is annular, and the outer wall of the battery holder is provided with an external thread. The inner wall of the receiving groove is provided with an internal thread that matches the external thread of the battery holder.

[0012] This utility model discloses a water immersion sensor that is easy to install. When installed, the bottom surface of the fixing post away from the cover plate body and the housing of the water immersion sensor is provided with an adhesive layer, and the side of the adhesive layer away from the fixing post and the housing of the water immersion sensor is provided with an anti-sticking layer.

[0013] This utility model provides a water immersion sensor that is easy to install, wherein when installed in place, a first waterproof ring is fitted onto the lower end of the fixing column.

[0015] The beneficial effects of this utility model are as follows:

[0016] The gateway features a mounting base on its upper surface, with a protruding battery holder threadedly connected to the mounting base beneath the water immersion sensor. This allows users to easily remove the water immersion sensor from the mounting base without any tools, exposing the battery holder. This completely eliminates the cumbersome steps of rotating, prying open the cover, or using a screwdriver found in traditional designs, significantly improving the convenience and efficiency of battery replacement. The threaded engagement between the cover assembly and the fixing post ensures that the battery is securely held in place from above by the fixing post after insertion into the battery holder, creating a stable longitudinal restraint. This integrated design improves assembly reliability while reducing structural complexity, facilitating further reduction in sensor size and extending battery life. Attached Figure Description
