[0041] Embodiments of the present application will be described in more detail by referring to the drawings. Although embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to convey the scope of the present application to those skilled in the art.

[0042] It should be understood that although the terms "first", "second", "third", etc. are used to describe various information in the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the present application. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0043] ​In the description of the utility model, it is understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0044] Unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, can be fixed connection, can also be detachable connection or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0045] As shown in Figure 1 and Figure 2 , the water level detection device 10 in some embodiments of the utility model, connected to the sink 20, the water level detection device 10 includes support 1 and detection mechanism 2.It should be noted that the support 1 is used to provide a space or position for installing detection mechanism 2 in the sink 20.Detection mechanism 2 is arranged on the support 1.The sink 20 as a liquid container to be measured can be a washing machine, a water heater, a base station or other equipment that needs to detect the water level.

[0046] As shown in Figures 3 to 9 , the support 1 is connected to the sink 20, so that the support 1 and the tank wall of the sink 20 are provided with a floating space 30, and the floating space 30 is communicated with the sink 20.

[0047] The detection mechanism 2 includes a floating member 21, a first sensing member 22 and a second sensing member 23 (the second sensing member 23 is shown in Figure 9 ), the floating member 21 is movably arranged in the floating space 30 (the floating space 30 is shown in Figure 4 and Figure 9 ), the first sensing member 22 is arranged in the floating member 21, and the second sensing member 23 is arranged outside the sink 20, when the floating member 21 drives the first sensing member 22 to move to the position corresponding to the second sensing member 23 in the floating space 30, the first sensing member 22 triggers the second sensing member 23.

[0048] It can be understood that the floating member 21 moves freely up and down within the floating space 30. The floating member 21 can move the first sensing member 22 up and down as the water level changes. The first sensing member 22 is arranged inside the floating member 21. When the floating member 21 rises to a certain height with the water level, it will trigger the second sensing member 23. The second sensing member 23 is located outside the sink 20 and connected to the water level control related circuit board or control circuit, etc. Whether the second sensing member 23 is triggered by the first sensing member 22 can determine whether the predetermined water level in the sink 20 is reached.

[0049] It should be noted that when the water level in the sink 20 begins to rise, the floating member 21 will float up due to the buoyancy. As the water level continues to rise, the floating member 21 moves the first sensing member 22 inside it upwards. When the water level reaches the preset height, the first sensing member 22 aligns with the position of the second sensing member 23 located outside the sink. The first sensing member 22 triggers the second sensing member 23, generating an electrical or magnetic signal. This signal is transmitted to the control system (related circuit board or control circuit). After receiving the signal, the control system can take appropriate actions, such as stopping water or issuing an alarm.

[0050] It should also be noted that by setting a compact floating space 30, the entire detection mechanism can be integrated into the limited space of the sink 20. The floating member 21 and the first sensing member 22 are both located within the floating space 30, reducing the number of external components and significantly reducing the overall space occupied.

[0051] The bracket 1 can be flexibly installed at different positions of the sink 20 according to actual needs, without strict limitation of specific installation points. This setting allows users to adjust according to the site conditions, improving the flexibility of installation. The floating member 21 is arranged to move freely within the floating space 30, without being limited by the installation position, ensuring normal operation even in different shaped sinks.

[0052] Secondly, the water level detection device 10 can also be applied to various types of sinks and application scenarios. Whether it is a regular shape or an irregular shape, as long as an effective floating space 30 can be formed, the detection device can be used.

[0053] Further, the floating space 30 can include at least the following implementation ways:

[0054] First, the floating space 30 can be configured as a space jointly defined by the bracket 1 and the tank wall of the sink 20;

[0055] Secondly, the floating space 30 can be configured to be formed entirely by the groove, channel or various limiting structures (limiting wall or limiting protrusion, etc.) on the support 1. In such embodiments, the floating space 30 for the floating part 21 to float with the water level can be formed without relying on the groove wall of the water tank 20.

[0056] Third, the floating space 30 can be configured to be entirely defined by the groove, channel or other limiting structure with a certain amount of protrusion in the prior art that is opened on the wall of the water tank 20. In this embodiment, the bracket 1 only serves to limit the floating member 21 within the space, or the bracket 1 does not serve to limit the floating member 21, but serves to protect the floating member 21 and prevent foreign objects in the liquid from entering the floating space.

[0057] like Figures 3 to 8 As shown, in some embodiments of the water level detection device 10, the floating space 30 is defined by the support and the wall of the water tank 20 in the following embodiment: the support 1 includes a baffle 11, an upper baffle 12, a lower baffle 13 and two side baffles 14, and the baffle 11 is connected to the water tank 20.

[0058] The upper baffle 12, the lower baffle 13 and the two side baffles 14 are respectively disposed on the baffle 11. The two side baffles 14 are opposite each other and there is a clearance interval 141 between them. The upper baffle 12 and the lower baffle 13 are opposite each other and there is a start and end interval between them. The baffle 11, the upper baffle 12, the lower baffle 13, the two side baffles 14 and the wall of the water tank 20 together define the floating space 30.

[0059] Understandably, the baffle 11 is directly connected to the wall or outside of the water tank 20, serving a supporting and fixing function. The baffle 11 can be made of corrosion-resistant materials, such as stainless steel or corrosion-resistant plastic, to ensure long-term stability. The upper baffle 12 is located on the upper part of the baffle 11 to limit the rising height of the floating component 21. The upper baffle 12 can be a horizontally placed plate-like structure, fixed to the baffle 11 with screws or other fasteners. The lower baffle 13 is located on the lower part of the baffle 11 to limit the falling height of the floating component 21. The lower baffle 13 can also be a horizontally placed plate-like structure, fixed to the baffle 11 with screws or other fasteners. Two side baffles 14 are positioned opposite each other on both sides of the baffle 11, with a clearance gap 141 between them, allowing the floating component 21 to move freely within this gap. Each side baffle 14 is fixedly connected to the baffle 11 to ensure structural stability. The side baffle 14 can be a vertically placed plate-like structure, fixed to the baffle 11 by welding, screws or other fasteners.

[0060] Further, the baffle 11, the upper blocking piece 12, the lower blocking piece 13 and the two side blocking pieces 14 can be configured as an integrally formed structure, thereby improving the overall structural strength of the bracket 1 and eliminating the need for setting a bolt or a buckle or other connecting mechanism at the connecting position to ensure high compactness of the bracket 1.

[0061] As shown in FIG. 1, in some embodiments of the water level detection device 10, the baffle 11 is provided with a flow guide window 111, which is in communication with the water tank 20 and the floating space 30. Figures 5 to 8

[0062] As can be understood, the flow guide window 111 allows water to flow freely into the floating space 30, thereby ensuring that the floating piece 21 can move with the change of the water level. The flow guide window 111 can be a rectangular, circular or other shaped opening, the size and position of which are set according to actual needs.

[0063] As shown in FIG. 1, in some embodiments of the water level detection device 10, the bottom of each side blocking piece 14 is provided with an inflow gap 17 between the lower blocking piece 13, and the inflow gap 17 is in communication with the water tank 20 and the floating space 30. Figures 3 to 8

[0064] As can be understood, the inflow gap 17 is for the liquid between the water tank 20 and the floating space 30 to flow, ensuring that the water tank 20 and the floating space 30 can timely communicate the liquid. The height and width of the inflow gap 17 should be designed to ensure sufficient water flow while not affecting the normal movement of the floating piece 21.

[0065] As shown in FIG. 1 and FIG. 2, in some embodiments of the water level detection device 10, the thickness of the lower blocking piece 13 gradually decreases away from the floating space 30, thereby forming a mounting slope 131 on the lower blocking piece 13. Figure 6 Figure 7 As can be understood, the mounting slope 131 is provided to facilitate the insertion of the floating piece 21 into the floating space 30 from the outside, preventing the floating piece 21 from being stuck outside the floating space 30 during installation.

[0066] As can be understood, the mounting slope 131 is provided to facilitate the insertion of the floating piece 21 into the floating space 30 from the outside, preventing the floating piece 21 from being stuck outside the floating space 30 during installation.

[0067] As shown in FIG. 1, in some embodiments of the water level detection device 10, the bracket 1 is provided with a mounting wing 15; the mounting wing 15 is used for corresponding installation on the water tank 20. The connection between the mounting wing 15 and the water tank 20 has at least the following implementation manners: Figures 4 to 8 The first implementation manner is that a plurality of mounting holes 151 are provided on the mounting wing 15, and the mounting holes 151 are provided for the bolts to pass through and be screwed to the water tank 20.

[0068] The first implementation manner is that a plurality of mounting holes 151 are provided on the mounting wing 15, and the mounting holes 151 are provided for the bolts to pass through and be screwed to the water tank 20.

[0069] ​​​It can be understood that the mounting hole 151 can be screwed into the sink 20 to correspondingly screw to the sink 20, thereby fixing the installation wing 15 in the sink 20, and further fixing the bracket 1 in the sink 20.

[0070] In a second embodiment, the installation wing 15 is provided with a clamping part, and the installation wing 15 is clamped to the sink 20.

[0071] It can be understood that a clamping groove can be formed on the sink 20, so that the clamping part can be correspondingly clamped and fixed to the clamping groove on the sink 20.

[0072] In a third embodiment, the installation wing 15 is provided with a plug-in part, and the plug-in part is plugged into the sink 20.

[0073] It can be understood that a plug-in groove can be formed on the sink 20, so that the plug-in part can be correspondingly plugged into the sink 20.

[0074] As shown in Figures 4 to 9 In some embodiments of the water level detection device 10, the first sensing part 22 includes a magnetic part, and the second sensing part 23 includes a Hall switch.

[0075] It can be understood that the first sensing part 22 includes a magnetic part, which is arranged inside the floating part 21. The magnetic part can be a permanent magnet, such as a neodymium iron boron magnet or a ferrite magnet. The position of the magnetic part should ensure that it can move with the movement of the floating part 21, and can approach the second sensing part 23 when reaching a predetermined water level.

[0076] As shown in Figure 7 In some embodiments of the water level detection device 10, the first sensing part 22 is arranged on the central axis L1 in the thickness direction of the floating part 21.

[0077] It can be understood that the second sensing part 23 includes a Hall switch, which is located outside the sink 20 and connected to the control system. The Hall switch is a sensor based on the Hall effect. When the magnetic part approaches the Hall switch, the Hall switch will generate an electrical signal, thereby triggering the control system to perform corresponding operations.

[0078] It should be noted that the control system can be a circuit board or other circuit with control function commonly used in the prior art.

[0079] As shown in Figure 4 and Figures 6 to 8 In some embodiments of the water level detection device 10, the floating part 21 includes a first semicircular shell 211 and a second semicircular shell 212, and the first semicircular shell 211 is connected to the second semicircular shell 212.

[0080] It can be understood that the first semicircular shell 211 is part of the floating member 21, which is generally semicircular or similar in shape to adapt to the internal space of the sink 20. The second semicircular shell 212 corresponds to the first semicircular shell 211 and is also semicircular or similar in shape.

[0081] It should be noted that the cross section of the semicircular shell in the embodiments of the present application is circular, and the first semicircular shell 211 and the second semicircular shell 212 are assembled to form a cylindrical or pie shape.

[0082] It should also be noted that the first semicircular shell 211 and the second semicircular shell 212 can be configured as left and right cover connection or upper and lower cover connection.

[0083] As shown in Figure 4 and Figure 8 In some embodiments of the water level detection device 10, the center of the first semicircular shell 211 or the center of the second semicircular shell 212 is provided with a mounting groove 213, and the second sensing member 23 is arranged in the mounting groove 213.

[0084] The edge of the first semicircular shell 211 is provided with a positioning groove 2111, and the edge of the second semicircular shell 212 is provided with a positioning protrusion 2121, and the positioning protrusion 2121 is inserted into the mounting groove 213.

[0085] It can be understood that the mounting groove 213 is used to accommodate the second sensing member 23 (Hall switch), so as to ensure that the position is fixed and cannot be moved. The setting position of the mounting groove 213 can avoid the deflection of the floating member 21 due to the weight of the second sensing member 23 during the floating process, so as to ensure that the second sensing member 23 can correspond to the first sensing member 22 when the floating member 21 is in a predetermined position, that is, to ensure that the second sensing member 23 can trigger the second sensing member 23 in time, thereby completing the water level detection in time and accurately.

[0086] As shown in Figure 9 The base station 40 of the utility model includes a base station body 50, a water level detection device 10 and a sink 20. The sink is arranged on the base station body, the second sensing member is arranged in the base station body, the base station body is provided with a control circuit board, and the control circuit board is electrically connected to the second sensing member.

[0087] It can be understood that the base station can be various devices requiring water storage function in the prior art, such as washing machine, water heater, sweeping base station or other devices requiring water level detection. The control circuit board is used to receive the electrical signal from the second sensing member, so that when the second sensing member is triggered by the first sensing member, the control circuit board can control the corresponding mechanism when the water level alarm.

[0088] The implementation of the utility model has the following beneficial effects:

[0089] The utility model relates to a water level detection device and base station, and the base station is provided with the water level detection device.

[0090] Secondly, since the floating space is directly communicated with the water tank, and the first sensing member is located in the floating member and the second sensing member is placed outside the water tank, the configuration mode greatly reduces the requirement for the specific position of the sensor.

[0091] Furthermore, the utility model can work normally as long as the effective formation of the floating space is ensured whether it is applied to the regular or irregular water storage container, which greatly widens the application range.

[0092] In addition, although the utility model increases the components such as the floating member, the overall structure is simple and clear, and the application of complex and expensive parts is avoided; meanwhile, the production and assembly process is relatively simple and fast, which helps to reduce the manufacturing cost.

[0093] The utility model has been described in detail above with reference to the drawings. In the above embodiment, the description of each embodiment has its own emphasis, and the part not described in detail in a certain embodiment can be referred to the relevant description of other embodiments. It should be known by those skilled in the art that the acts and modules involved in the specification are not necessarily required by the utility model. In addition, it can be understood that the steps in the embodiment method of the utility model can be adjusted, combined and reduced in sequence according to actual needs, and the modules in the embodiment device of the utility model can be combined, divided and reduced according to actual needs.
