Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of liquid level controllers, in particular to a piston motion type liquid level controller. Background Art
[0002] A liquid level controller is a device that controls the high and low water levels by mechanical or electronic methods. It can control solenoid valves, water pumps, etc. to become an automatic water level controller or a water level alarm. A float is usually used to determine whether the water level has reached the warning value. The float is not protected from being easily affected by impurities such as garbage when working underwater. A net tube is usually used to shield and protect the float. However, the net tube is easily blocked by impurities after long-term use, which affects the floating of the float. A structure is proposed to prevent impurities such as garbage from affecting the float. Utility Model Content

[0018] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific liner 204 described in the above embodiment. For example, a sealing rubber ring is provided at the connection between the liner 204 and the connecting rod 203 and the shell 101. The purpose of this setting is to prevent garbage and impurities from entering the shell 101 in this way.
[0019] Specifically, an external gear 205 is fixedly connected to the bottom of the connecting rod 203 . The external gear 205 is meshedly connected to a gear ring 206 . The gear ring 206 is fixedly connected to the housing 101 .
[0020] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific shell 101 described in the above embodiments. For example, the shell 101 can be fixed by screws on its side. The purpose of this setting is to prevent the shell 101 from moving due to water flow in this way.
[0021] Specifically, the outer gear 205 is meshedly connected with the main gear 207 , and a connecting rod A208 is fixedly connected to the axis of the main gear 207 , and the connecting rod A208 is rotatably connected to the housing 101 .

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0034] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.
[0035] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.
[0036] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.
[0037] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.
[0038] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.
