[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] like Figures 1 to 7 As shown, this embodiment of the utility model provides a water immersion detector, which includes a housing and a detection assembly. The housing has a receiving cavity and two opposing ends, a first end 01 and a second end 02. The end face of the first end 01 has a confluence recess 10, and the second end 02 has a wall-mounting structure. The detection assembly includes a first probe 21, a control board 30, and a detection probe 40. The control board 30 is located inside the receiving cavity. One end of the first probe 21 is electrically connected to the control board 30, and the other end of the first probe 21 extends to the outside of the receiving cavity and is located inside the confluence recess 10. The detection probe 40 is detachably connected to the housing and is used for electrical connection with the control board 30. The water immersion detector has a horizontal state and a wall-mounted state. When the water immersion detector is in the horizontal state, the detection assembly can collect signals through the first probe 21. When the water immersion detector is in the wall-mounted state, the detection probe 40 is fixed to the housing and electrically connected to the control board 30, and the detection assembly collects signals through the detection probe 40.

[0042] The technical scheme of the utility model, the water immersion detector has two use states of horizontal and wall hanging, when the water immersion detector is in the horizontal state, the water drop can be collected by the confluence recess 10 arranged at the first end 01 of the shell, because one end of the first probe 21 is electrically connected with the control panel 30 in the containing cavity, the other end of the first probe 21 is arranged outside the containing cavity and is located in the confluence recess 10, therefore the part of the first probe 21 that is arranged outside the containing cavity can detect and feedback the water in the confluence recess 10. When the detection space of the water immersion detector is limited and cannot be detected, the water immersion detector can be hung on a wall surface through the wall hanging structure of the second end 02 of the shell first, and then the detection probe 40 is used to collect the liquid level signal in the water immersion area. The detection probe 40 is detachably connected with the shell, so that the water immersion detector is more flexible in switching between the horizontal and wall hanging states, and the occupied space can be reduced. Through the above structure design and state conversion, the embodiment can realize efficient, convenient and accurate water immersion detection function in different use scenarios, and meet various detection requirements.

[0043] Specifically, the wall hanging structure includes but is not limited to a hook, a nail or other fixing devices for stably fixing the detector on a wall or other vertical surface.

[0044] Further, the detection assembly further includes a second probe 22, one end of the second probe 22 is electrically connected with the control panel 30, and the other end of the second probe 22 is arranged outside the containing cavity and located at the second end 02 of the shell. In the embodiment, one end of the second probe 22 is connected with the circuit on the control panel 30, and the other end of the second probe 22 can be arranged outside the containing cavity and protrude from the second end 02 of the shell. When the water immersion detector is in the horizontal state and the ground is in the water accumulation state, the part of the second probe 22 arranged outside the containing cavity will contact the water accumulation. Because of the conductivity of water, a closed loop is formed between the second probe 22 and the control panel 30, and then the detection feedback is completed.

[0045] Further, the shell further includes a mounting hanging plate 50, the mounting hanging plate 50 is detachably connected with the second end 02 of the shell to form a wall hanging structure. In the embodiment, the mounting hanging plate 50 is a plate structure and is detachably connected with the second end 02 of the shell, so that the water immersion detector can simply and flexibly change its working state. During installation, the mounting hanging plate 50 is first fixed on the wall surface or other required position by screws, and then the second end 02 of the water immersion detector is fixedly connected with the mounting hanging plate 50 to complete the installation.

[0046] Specifically, at least one screw hole can be arranged on the mounting hanging plate 50 for being fixed on the wall or other supporting surface by screws, and a non-slip pad is arranged on the side of the mounting hanging plate 50 facing the wall to increase the friction between the mounting hanging plate 50 and the wall, avoid accidental falling and improve the fixing effect.

[0047] Further, the mounting plate 50 is provided with a connecting portion 51, the connecting portion 51 is provided on the mounting plate 50, when the water immersion detector is in the wall-mounted state, the detection probe 40 is electrically connected with one end of the connecting portion 51, the other end of the connecting portion 51 is electrically connected with the second probe 22, and the detection probe 40 is electrically connected with the control panel 30 through the connecting portion 51 and the second probe 22.

[0048] In the embodiment, when the water immersion detector is in the wall-mounted state, the connecting portion 51 serves to connect the detection probe 40 and the second probe 22. One end of the connecting portion 51 is in contact with the detection probe 40, and the other end is connected with the second probe 22. Since the second probe 22 is electrically connected with the control panel 30, the detection probe 40 can be directly electrically connected with the control panel 30 in the containing cavity through the connecting portion 51. The probe cable can be deep into the container or area where the liquid level needs to be detected for detection, and then transmitted to the control panel 30 through the connecting portion 51, so as to realize accurate monitoring of the liquid level. The control panel 30 can judge whether the water immersion phenomenon occurs after receiving the signal.

[0049] As shown in Figure 5 and Figure 6 , one end of the connecting portion 51 connected with the second probe 22 has an elastic clamping groove 511, and the shell has a dismounting position and a mounting position relative to the mounting plate 50. When the shell is in the mounting position, the shell is fixedly connected with the mounting plate 50, and the second probe 22 is clamped and connected with the elastic clamping groove 511. When the shell is in the dismounting position, the shell is separated from the mounting plate 50, and the second probe 22 is disconnected with the connecting portion 51. In the embodiment, the elastic clamping groove 511 is arranged at the end of the connecting portion 51 connected with the second probe 22. The elastic clamping groove 511 can realize flexible switching of the dismounting position and the mounting position of the shell relative to the mounting plate 50.

[0050] Specifically, the elastic clamping groove 511 can be provided in a trapezoidal structure, and the size of the slot is slightly larger than the diameter of the second probe 22, so as to ensure that the second probe 22 can enter the slot in the mounting state. The middle part of the elastic clamping groove 511 is gradually narrowed, so that the elastic clamping groove 511 can elastically clamp the second probe 22, fix the position of the second probe 22 relative to the elastic clamping groove 511, prevent the second probe 22 from loosening after clamping, and generate a proper extrusion force to realize close contact between the elastic clamping groove 511 and the second probe 22.

[0051] Specifically, the elastic clamping groove 511 can be a clamping groove structure made of a metal sheet with a certain elasticity or an elastic material. When the shell is in the dismounting position relative to the mounting plate 50, the elastic clamping groove 511 can quickly recover to the original state and will not be permanently deformed due to long-term use.

[0052] Specifically, the connecting part 51 itself is a contact spring, which is fixed on the second end 02 and is in a sheet shape, and has a certain bending degree, so as to generate sufficient elastic force when the second probe 22 contacts the contact spring, to maintain the tightness and sensitivity of the contact.

[0053] As shown in Figure 2 and Figure 3 , the mounting hanging plate 50 and the shell are detachably connected through the buckle structure 52. In the embodiment, the mounting hanging plate 50 and the shell are detachably connected through the buckle structure 52, which is convenient to change the level or wall-mounted state of the water immersion detector at any time, and is more convenient and flexible in use. The buckle structure 52 is easy to install and detach, and can effectively prevent the water immersion detector from accidentally falling off due to external force.

[0054] Further, the buckle structure 52 includes a plurality of clamping grooves 521 and a plurality of protrusions 522, the plurality of clamping grooves 521 are annularly and spacedly distributed on the mounting hanging plate 50, and the plurality of protrusions 522 are annularly and spacedly distributed on the second end 02 of the shell. The protrusions 522 are arranged one by one corresponding to the clamping grooves 521, and the protrusions 522 and the clamping grooves 521 cooperate to form the buckle structure 52. In the embodiment, the plurality of clamping grooves 521 on the mounting hanging plate 50 are evenly distributed around the center of the hanging plate, which can ensure the balance of the buckle structure 52. The opening direction of the clamping groove 521 is designed to face the center of the hanging plate, so that the protrusions 522 on the second end 02 of the shell can smoothly slide into the clamping grooves 521 during installation, and also ensure the stability of the buckle during use, avoiding loosening due to external force.

[0055] During installation of the water immersion detector, the user only needs to align the protrusions 522 on the second end 02 of the shell with the adjacent intervals of the clamping grooves 521 on the mounting hanging plate 50, and then rotate the shell. The protrusions 522 on the shell can be embedded one by one into the clamping grooves 521 on the mounting hanging plate 50, thereby forming the buckle structure 52, which is simple and fast, and does not require the use of additional tools or fasteners. At the same time, the second probe 22 is clamped into the elastic clamping groove 511 of the connecting part 51 due to the rotating force, and the connection of the detection probe 40 is completed. When the detection is completed, the shell is reversely rotated, and the disassembly of the shell and the detection probe 40 is completed, which greatly improves the efficiency of installation and disassembly.

[0056] As shown in Figure 1 , the shell includes a lower cover assembly 61 and an upper cover assembly 62, the lower cover assembly 61 and the upper cover assembly 62 are detachably connected, the upper cover assembly 62 and the lower cover assembly 61 cooperate to form a containing cavity, and the upper cover assembly 62 has a first end 01, and the first probe 21 is arranged on the upper cover assembly 62.

[0057] In this embodiment, the housing consists of two parts: a lower cover assembly 61 and an upper cover assembly 62. These two parts are connected in a detachable manner to facilitate the assembly, maintenance, and replacement of the water immersion detector. The upper cover assembly 62 and the lower cover assembly 61 fit tightly together to form a receiving cavity, which is used to house core components such as the control board 30. The structure is simple, with few parts, and easy to install.

[0058] like Figure 1 As shown, a sealing element 63 is provided between the lower cover assembly 61 and the upper cover assembly 62, and the sealing element 63 is located at the connection between the lower cover assembly 61 and the upper cover assembly 62. In this embodiment, the sealing element 63 provided between the upper and lower cover assemblies 61 can ensure the waterproof performance of the water immersion detector in various operating environments. In particular, when placed horizontally, it can effectively prevent water from entering the device, ensuring the normal operation of the control board 30 circuit. At the same time, it can also prevent dust from entering the device, ensuring that the circuit board and electronic components work stably in humid or water-dripping environments.

[0059] Specifically, the seal 63 can be made of silicone material with high elasticity and waterproof properties, which has good compressibility and resilience, and can maintain good sealing performance after long-term use to prevent moisture intrusion.

[0060] Furthermore, the second end 02 has a support portion that supports the housing. The end of the support portion furthest from the housing protrudes beyond the outer end of the second probe 22 located on the housing's exterior. In this embodiment, the support portion is a structure extending outward from the second end 02 of the housing, used to support the entire water immersion detector. In use, the support portion directly contacts a wall or ground, improving the detector's stability and preventing swaying or tilting due to external forces or its own weight, ensuring accurate detection by the detection components.

[0061] Specifically, the protrusion 522 can also be configured as a support, thereby reducing the number of parts in the housing and enabling the protrusion 522 to simultaneously support the housing and connect the mounting plate 50.

[0062] Specifically, the material of the support is preferably a corrosion-resistant metal or a high-strength plastic to ensure that its structural strength is not affected by long-term use in a humid environment.
