Description

Technical Field

[0001] This utility model relates to the field of drainer technology, and specifically to a drainer with a high-precision liquid level detection component. Background Technology

[0002] A drain is a device whose main function is to guide water flow from indoors or outdoors to sewers or other drainage systems, ensuring the smooth operation of the piping system. Drains play a crucial role in piping systems, responsible for removing liquids or wastewater and ensuring the normal operation of the system.

[0003] Existing drain products mostly adopt timed discharge mechanisms and are widely used in industrial and civil drainage systems. A typical structure includes a shell, a timed control circuit and a solenoid valve. The working principle is to trigger the valve to open and close at a preset time interval to achieve periodic discharge of liquid or gas. However, these traditional drains have significant defects because they rely only on fixed time to drive and ignore the actual liquid level. They still perform discharge when the liquid level is insufficient, resulting in energy waste and low system efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a drainer with a high-precision liquid level detection component, characterized in that: it includes a shell assembly 1, a drain assembly 3 is installed at the bottom of the shell assembly 1, and a control component 2 for controlling the start and stop of the drain assembly 3 is installed inside the shell assembly 1. The shell assembly 1 includes a shell body 11, and a mounting groove 12 is provided through the top of the shell body 11. The control component 2 includes a circuit board 21 and a liquid level sensor 25. A connecting block 23 is electrically connected to the top of the circuit board 21, and a docking groove 24 is provided on the top of the connecting block 23. One end of the liquid level sensor 25 passes through the mounting groove 12 into the interior of the shell body 11, and one end of the liquid level sensor 25 is electrically connected to the connecting block 23 through the docking groove 24. A liquid level probe 26 for measuring the liquid level is electrically connected to the top of the liquid level sensor 25.

[0023] By controlling component 2 and utilizing the connection between circuit board 21, liquid level sensor 25, liquid level probe 26, connecting block 23, and docking groove 24, liquid level probe 26 transmits the liquid level height inside the container to be drained to liquid level sensor 25 in real time. Liquid level sensor 25 transmits the signal to circuit board 21 through connecting block 23. The signal processor on circuit board 21 analyzes and processes the signal. When the liquid level height reaches the threshold, drainage component 3 is activated to drain the liquid, avoiding energy waste caused by timed opening of solenoid valve 32. Furthermore, liquid level sensor 25 is installed via a movable plug-in connection, facilitating replacement and maintenance of the liquid level sensor.

[0024] A protective cover 13 is placed on the top of the liquid level sensor 25. Two sets of bolts 14 are movably installed through the top of the protective cover 13. The bottom ends of the two sets of bolts 14 are bolted to the top of the outer shell 11. Through the connection between the protective cover 13, the bolts 14 and the outer shell 11, the protective cover 13 can be quickly installed and removed. At the same time, the protective cover 13 plays a role in protecting and limiting the liquid level sensor 25.

[0025] The outer side of the protective cover 13 is provided with a through-hole groove 15. The liquid level probe 26 passes through the through-hole groove 15 to the outer side of the protective cover 13. Through the connection relationship between the protective cover 13, the through-hole groove 15 and the liquid level probe 26, the connection end of the liquid level probe 26 is protected and hidden without affecting the use of the liquid level probe 26, thereby improving aesthetics and practicality.

[0026] One end of the circuit board 21 is electrically connected to a power cord 22. The bottom of the outer casing 11 is connected to a locking clip 18. One end of the power cord 22 passes through the locking clip 18 to the outside of the outer casing 11. One end of the power cord 22 is connected to a power source, so that the power cord 22 can transmit electrical energy to the entire device. At the same time, the locking clip 18 facilitates the installation and fixation of the power cord 22 and improves the installation stability of the power cord 22.

[0027] One end of the circuit board 21 is electrically connected to the data line 27, and the other end of the data line 27 is electrically connected to the control panel 28. The control panel 28 includes an LCD display and buttons, and the liquid level threshold and drainage cycle are set through the control panel 28.

[0028] The outer side of the outer shell 11 has a through slot 16. One end of the control panel 28 is snapped into the inside of the slot 16. Through the connection between the outer shell 11, the slot 16 and the control panel 28, the control panel 28 can be quickly installed through the slot 16, and at the same time, it is convenient to operate the control panel 28 from the outside.

[0029] The drainage assembly 3 includes a drain pipe 31, a solenoid valve 32 is installed in the middle of the drain pipe 31, and a control line 33 is electrically connected to the top of the solenoid valve 32. One end of the control line 33 passes through the interior of the housing body 11 and is electrically connected to one end of the circuit board 21. When the liquid level reaches the threshold, the actuator on the circuit board 21 activates the solenoid valve 32 through the control line, so that the drain pipe 31 automatically starts to drain.

[0030] A retaining ring 17 is fixedly installed at the bottom of the housing body 11. The bottom of the retaining ring 17 is fitted onto the top of the solenoid valve 32. The retaining ring 17 facilitates quick installation and disassembly between the housing body 11 and the solenoid valve 32.

[0031] In practical use, one end of the drain pipe 31 is connected to the container that needs to be drained, and the liquid level probe 26 is placed inside the container. The liquid level threshold and drainage cycle are set through the control panel 28. The liquid level probe 26 transmits the water level height signal inside the container to the liquid level sensor 25. The liquid level sensor 25 transmits the signal to the processor of the circuit board 21. The processor of the circuit board 21 processes the data transmitted by the sensor. When the liquid level reaches the threshold, the actuator on the circuit board 21 starts the solenoid valve 32 through the control line 33, so that the drain pipe 31 automatically starts draining. After the drainage is completed, the solenoid valve 32 automatically closes. The liquid level sensor 25 is set to achieve real-time monitoring of the liquid level height, which avoids the solenoid valve 32 from continuing to discharge when the liquid level is insufficient, thus improving the efficiency of the solenoid valve 32.
