[0004] This invention is implemented as follows: an intelligent liquid extraction and addition device includes a lid body with an adapter for connecting to an external pipe. A ratchet component is fixedly installed on the lid body, the ratchet component containing multiple ratchet teeth that can deform to one side. A ratchet cover is rotatably mounted on the lid body, the ratchet cover having grooves that engage with the ratchet teeth. A sensor assembly is connected to the side of the lid body away from the ratchet cover via a cascaded structure. The sensor assembly is used to detect the remaining liquid level in the container, and the cascaded structure controls the depth of the sensor assembly inside the container.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, this is an embodiment of the present invention providing an intelligent liquid extraction device. The device includes a cover body 4, an adapter 5 installed on the cover body 4 for connecting to an external pipe, a ratchet component 3 fixedly installed on the cover body 4, the ratchet component 3 containing multiple ratches, the ratches being deformable to one side, a ratchet cover 1 rotatably mounted on the cover body 4, the ratchet cover 1 having a tooth groove that engages with the ratchet, a sensor assembly connected to the side of the cover body 4 away from the ratchet cover 1 via a cascade structure 7, the sensor assembly for detecting the remaining liquid in the container, the cascade structure 7 for controlling the depth of the sensor assembly inside the container, and an air hole provided on the cover body 4 for balancing the pressure inside the container.

[0021] In this embodiment of the utility model, during installation, the adapter 5 is installed onto the cover body 4; the sensor 8 is placed inside the sensor housing 9 and fixed; the cascade structure 7 is installed onto the cover body 4, and the sensor housing 9 is installed onto the cascade structure 7; the magnetic ring 10 is fitted into the cylindrical rod of the sensor housing 9, and the magnetic ring bracket 11 is installed onto the sensor housing 9 to prevent the magnetic ring 10 from falling off; the sealing gasket 6 is installed onto the cover body 4; the ratchet component 3 is installed onto the cover body 4 using the fixing screw 2; the ratchet cover 1 is installed onto the ratchet component 3; and the threaded sleeve 12 is installed onto the cover body 4.

[0022] In this embodiment of the utility model, the functions of each component are as follows:

[0023] Ratchet cap 1: Used to fasten and tighten the cap. It works with the ratchet teeth on the ratchet component 3 to secure the device to the container. Existing technology cannot control the amount of force required to install the cap, which can lead to insufficient sealing or the cap falling off during use if the force is too great or too small. The ratchet cap has a groove on the outside to increase the friction of the palm contact surface and improve force distribution when tightening.

[0024] Fixing screw 2: It serves to secure the connection between the ratchet component 3 and the cover body 4.

[0025] Ratchet component 3: Equipped with ratchet teeth, which work in conjunction with ratchet cover 1: When ratchet cover 1 rotates clockwise, it tightens the threads of cover body 4. When the designed torque is reached, the ratchet teeth are bent and deformed under force, thereby reducing the force on the threads of cover body 4 until it can no longer rotate the cover body 4, thus achieving the tightening effect; When ratchet cover 1 rotates counterclockwise, it cannot cause the ratchet teeth to bend and deform under force, thus loosening the threads of cover body 4, thereby achieving the disassembly effect. Multiple slots are provided on the side for drainage.

[0026] The lid body 4 has multiple mounting holes, the number of which is not fixed and can be adjusted according to actual conditions. These holes, together with the fixing screws 2, secure the ratchet component 3. Multiple toothed plates prevent rainwater from splashing into the device; after blocking, rainwater drains out through the slots around the ratchet component 3. Multiple vents ensure atmospheric pressure balance inside and outside the container when adding or removing liquid. Threads are provided for fastening the device to the container. Input and output flow paths are provided; the adapter 5 is installed at the flow path opening to connect the inside and outside of the container.

[0027] Adapter 5: Installed on the lid body 4, it is used for the flow of liquid inside and outside the container. The pipeline is connected to the adapter, and the pump is used to pump or add liquid into the container.

[0028] Sealing gasket 6: After the lid body 4 is installed on the container, it is connected with the sealing gasket 6 to achieve a sealing effect, preventing the special liquid from evaporating and the impurities in the air from entering the container and causing the liquid inside the container to deteriorate; it also prevents external rainwater from adhering and seeping into the container.

[0029] Cascade Structure 7: Used to increase the detection depth of the device and adapt to containers of different depths. Cascade Structure 7 has an internal thread at one end and an external thread at the other end, and multiple sections can be stacked and combined for use.

[0030] Sensor 8: Used to transmit liquid level signals in the container and send the liquid level signals to the pump body to control the pump body to start or stop. The liquid level height set by the sensor 8 can be configured according to the needs of the scenario to meet different application requirements.

[0031] Sensor housing 9: It is threaded and installed on the cover body 4 for mounting sensor 8 and protecting sensor 8 from being wetted or damaged by liquid.

[0032] Magnetic ring 10: floats on the liquid surface and works with sensor 8 to detect the liquid level using magnetism.

[0033] Magnetic ring bracket 11: It is threaded and installed on the sensor housing 9 to prevent the magnetic ring from leaving the sensing range of the sensor 8.

[0034] Threaded sleeve 12: Double thread, namely internal thread and external thread, is installed on the lid body 4 to adapt to the installation of different diameter thread structures at the mouth of the container; it is provided with ratchet teeth to cooperate with the lid body 4 to prevent loosening after installation.

[0035] When using this invention: the device is installed at the mouth of a container, one end of the pipeline is connected to the adapter 5, and the other end is connected to the pump. When the sensor 8 detects that the liquid level in the container is low, it transmits the signal to the controller. After receiving the signal, the controller starts the pump and delivers the external liquid through the flow path to the adapter 5 on the cover body 4 of the device, and finally into the container. At this time, the liquid level in the container rises, and the magnetic ring 10 rises with the liquid level until the sensor 8 reaches a high liquid level. The sensor 8 sends a high liquid level signal to the controller, and the controller receives the signal and stops the pump, and the liquid delivery stops.

[0036] In one embodiment of this utility model, the vent can be replaced by two sets of one-way valves. That is, the vent is removed, and two sets of one-way valves are provided on the lid body 4, with the two sets of one-way valves installed in opposite directions. One one-way valve is used for venting, and the other one-way valve is used for venting. When the internal pressure of the container is too high, the one-way valve reaches the venting limit, and venting is carried out through one set of one-way valves to balance the internal and external pressure of the container. When the internal pressure of the container is too low, the one-way valve reaches the venting limit, and venting is carried in through the other set of one-way valves to balance the internal and external pressure of the container.

[0037] In one embodiment of this utility model, the cascade structure 7 can be replaced by a spring, utilizing the elastic properties of the spring to enable the device to be used in containers of different depths.

[0038] In one embodiment of this utility model, an inner adapter is also connected to the lid body 4, and a pipe is connected to the inner adapter. When the liquid inside the container is not used for a long time, the pump body can be controlled to run in reverse, thereby drawing out the liquid inside the container through the pipe and the inner adapter.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
