Description

Technical Field

[0001] The present invention relates to the technical field of drainers, and in particular to a drainer for an efficient drainage system and a method of using the same. Background Art

[0002] Most existing drain products adopt a timed discharge mechanism and are widely used in industrial and civil drainage systems. The typical structure includes a shell, a timing control circuit and a solenoid valve. The working principle is to trigger the valve switch through a preset time interval to achieve periodic discharge of liquid or gas.

[0003] For example, a drainer provided by announcement number CN219251904U includes a shell, a lower space and an upper space are formed inside the shell; a connected drainage hole is provided between the lower space and the upper space, and a water vapor inlet and a drainage outlet are provided on the side wall of the shell, and the water vapor inlet is connected to the lower space; a drainage component, the drainage component is arranged in the upper space, located on the drainage hole, and closes the drainage hole; a drainage channel is provided in the drainage component, and the drainage component moves from a first position to a second position under air pressure, so that the drainage hole is connected to the drainage channel, and the drainage channel is connected to the drainage outlet; a first filter component, the first filter component is sleeved in the upper space, and is located on the outside of the drainage component to prevent impurities from entering the upper space.

[0004] However, these traditional drainers have significant defects because they only rely on fixed-time driving and ignore the actual liquid level status. They still perform drainage when the liquid level is insufficient, resulting in energy waste and low system efficiency. They lack liquid level detection function and are difficult to adapt to dynamic drainage needs. They are prone to frequent valve operation and increase the risk of failure. Therefore, we need to propose a drainer for efficient drainage systems and its use method. Summary of the Invention

[0005] The object of the present invention is to provide a drainer for an efficient drainage system and a method of using the same. The water level is detected by a liquid level sensor. When the water level is higher than the set value, the solenoid valve is opened to drain the water. When the water level is lower than the set value, the solenoid valve is closed to prohibit drainage. The above scheme realizes the liquid level detection function of the water level, avoids discharge due to insufficient liquid level, reduces energy waste, improves system efficiency, can adapt to dynamic drainage needs, reduces frequent valve operation, and reduces the risk of failure, so as to solve the problems raised in the above background technology.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 The present invention provides a drainer for an efficient drainage system and a method for using the same, comprising a housing 1, a liquid level sensor 2 for detecting the water level, and a solenoid valve 3 installed in a drainage channel. A control panel 4 is provided on the surface of the housing 1. The surface of the control panel 4 is provided with an LCD display and several groups of arc-shaped buttons 5. The LCD display is centered, and the several groups of buttons 5 are located directly below and surrounding the LCD display. A circuit board 6 for determining a threshold value to drive the solenoid valve 3 is provided inside the housing 1. The circuit board 6 is connected to the control panel 4, the liquid level sensor 2, and the solenoid valve 3 through cables. The bottom end of the liquid level sensor 2 is connected to the solenoid valve 3, and the solenoid valve 3 is installed at the bottom end of the housing 1.

[0029] Specifically, after the drainer is installed, the liquid level and drainage cycle of the liquid level sensor 2 are first set through the button 5. The signal set by the button 5 is transmitted to the circuit board 6 through the cable. The circuit board 6 transmits the signal to the LCD display screen through the cable to feedback the adjustment parameters. The liquid level sensor 2 detects the height of the water level and transmits the signal of the water level height to the circuit board 6. The threshold is judged by the circuit board 6. When the water level is higher than the liquid level value, the circuit board 6 drives the solenoid valve 3 to switch and open the solenoid valve 3 for drainage. When the water level is lower than the liquid level value, the circuit board 6 drives the solenoid valve 3 to switch and close the solenoid valve 3 to prohibit drainage. The above scheme realizes the liquid level detection function of the water level, avoids discharge due to insufficient liquid level, reduces energy waste, improves system efficiency, can adapt to dynamic drainage needs, reduces frequent valve operation, and reduces the risk of failure.

[0030] Furthermore, a fixing structure 7 for fixing the cable is provided at the bottom end of the housing 1. The fixing structure 7 includes a cable clamp 71 and a waterproof sealing ring 72 installed inside the cable clamp 71. The inner wall of the cable clamp 71 is connected to the bottom end of the housing 1. The cable passes through the cable clamp 71, and then the cable clamp 71 is adjusted to clamp and fix the cable, thereby increasing the stability of the cable after being connected to the drainer and preventing the connection between the cable and the drainer from being affected by the impact of water flow and causing the connection to loosen.

[0031] Preferably, the shell 1 is set in a shield shape. Setting the shell 1 in a shield shape can improve the aesthetics of the shell 1. The shield-shaped structure is wide at the top and narrow at the bottom, which reduces space occupation. The inner cavity of the shell 1 is bolted to the circuit board 6 by bolts. The shell 1 and the circuit board 6 are bolted together so that the shell 1 and the circuit board 6 can be disassembled. When the circuit board 6 is damaged, it can be repaired and replaced. The bottom of the shell 1 is respectively connected to the liquid level sensor 2 and the solenoid valve 3 through a sealing gasket. After being connected through the sealing gasket, the sealing between the shell 1 and the liquid level sensor 2 and the solenoid valve 3 is improved, thereby improving the sealing effect.

[0032] Specifically, a hidden structure 8 for hiding the circuit is provided at the top of the solenoid valve 3. The hidden structure 8 includes a circuit cover 81 and a connecting port 82 opened at the top of the solenoid valve 3. The circuit cover 81 is connected to the solenoid valve 3 by bolts. The inner cavity of the connecting port 82 is provided with a wiring tube 83. The inner cavity of the wiring tube 83 is connected to the connecting circuit. A connecting groove 84 is provided at the bottom end of the circuit cover 81. The connecting circuit is inserted into the inner cavity of the wiring tube 83 and connected to the wiring tube 83. Then the wiring tube 83 is inserted into the inner cavity of the connecting port 82. Finally, the circuit cover 81 is covered to cover the connection between the circuit and the solenoid valve 3 to avoid exposure of the connection between the circuit and the solenoid valve 3. The connection of the solenoid valve 3 is optimized, thereby improving the aesthetics and stability of the connection of the solenoid valve 3.

[0033] In addition, a card slot 85 that is compatible with the connecting line is provided at the top of the wiring tube 83, and a connecting plate 86 is connected to the bottom end of the wiring tube 83. The bottom end of the connecting plate 86 is engaged with the inner cavity of the connecting port 82. The setting of the card slot 85 can cooperate with the circuit cover 81 to position the position of the connecting line, so as to avoid the external line shaking left and right due to the influence of water flow after the connecting line is connected to the solenoid valve 3, causing damage to the wiring point of the solenoid valve 3, thereby improving the stability of the connecting line after the wiring point of the solenoid valve 3 is connected. Through the cooperation of the connecting plate 86 and the connecting port 82, the position of the bottom end of the wiring tube 83 can be fixed, so as to avoid the angle deviation after the wiring tube 83 is connected to the wiring port.

[0034] Preferably, the solenoid valve 3 is arranged in a hexagonal shape, and the solenoid valve 3 includes a valve body upper shell 31 and a valve body lower shell 32. The outer wall of the valve body upper shell 31 is provided with a connecting hole 33 adapted to the connecting line, and the bottom end of the valve body upper shell 31 is provided with a connecting structure for connecting the valve body lower shell 32. The angular structure on the hexagon of the solenoid valve 3 optimizes the stress distribution, enhances the pressure resistance and corrosion resistance, and reduces the installation space requirement. Through the setting of the wiring hole, the connecting line can enter the inner cavity of the valve body lower shell 32 through the wiring hole and be connected to the valve body lower shell 32.

[0035] Furthermore, the connection structure includes an annular fixing plate 34 and an annular connecting seat 35. The top of the annular fixing plate 34 is connected to the bottom end of the valve body upper shell 31, and the bottom end of the annular connecting seat 35 is connected to the top of the valve body lower shell 32. The bottom end of the annular fixing plate 34 is connected with a threaded tube 36, and the inner cavity of the annular connecting seat 35 is threadedly connected to the surface of the threaded tube 36. At the same time, a sealing belt is provided at the bottom end of the annular fixing plate 34, which is threadedly connected to the annular connecting seat 35 through a threaded rod. The valve body upper shell 31 and the valve body lower shell 32 can be disassembled and installed by rotation. When the solenoid valve 3 is damaged, it provides convenience for the replacement of internal parts of the solenoid valve 3. Through the setting of the sealing belt, the sealing effect after the annular fixing plate 34 and the annular connecting seat 35 are connected is increased.

[0036] The present invention also provides a method for using a drainer for an efficient drainage system, comprising the following steps:

[0037] Step S1: Use button 5 to set the liquid level and drainage cycle of the liquid level sensor 2. The signal set by button 5 is transmitted to the circuit board 6 through the cable. The circuit board 6 transmits the signal to the LCD display screen through the cable to feedback the adjustment parameters.

[0038] Step S2: The liquid level sensor 2 detects the height of the water level. When the water level is greater than the value set by the liquid level sensor 2, the circuit board 6 determines the threshold. When the water level is higher than the value, the circuit board 6 sends a signal to the solenoid valve 3 through the wiring to drive the solenoid valve 3 to open and drain. After the drainage is completed, the circuit board 6 drives the solenoid valve 3 to open and close.

[0039] Step S3, the liquid level sensor 2 detects the height of the water level. When the water level is less than the value set by the liquid level sensor 2, the circuit board 6 determines the threshold. If the water level is lower than the value, the circuit board 6 sends a signal to the solenoid valve 3 through the wiring to drive the solenoid valve 3 to switch, so that the solenoid valve 3 is closed and drainage is prohibited.

[0040] When in use, first install the drainer, then press button 5 to set the liquid level and drainage cycle of the liquid level sensor 2. The signal set by button 5 is transmitted to the circuit board 6, and the circuit board 6 transmits the signal to the LCD display to feedback the adjustment parameters. The staff makes adjustments based on the parameters fed back on the LCD display.

[0041] When the drainer is draining, the liquid level sensor 2 detects the height of the water level. When the water level is greater than the value set by the liquid level sensor 2, the liquid level sensor 2 sends a signal to the circuit board 6. The circuit board 6 determines the threshold. If the water level is higher than the value, the circuit board 6 sends a signal to the solenoid valve 3 through the wiring to drive the solenoid valve 3 to open and drain. After the drainage is completed, the circuit board 6 drives the solenoid valve 3 to open and close.

[0042] When the water level is lower than the value set by the liquid level sensor 2, the liquid level sensor 2 sends a signal to the circuit board 6. The circuit board 6 determines the threshold value. If the water level is lower than the value, the circuit board 6 sends a signal to the solenoid valve 3 through the wiring to drive the solenoid valve 3 to switch, so that the solenoid valve 3 is closed and drainage is prohibited. The above scheme realizes the liquid level detection function of the water level, avoids discharge due to insufficient liquid level, reduces energy waste, improves system efficiency, can adapt to dynamic drainage needs, reduces frequent valve operation, and reduces the risk of failure.

[0043] The electronic circuit includes a main control circuit (MCU, STM32F103C8T6, for signal processing), a liquid level detection circuit (HC-SR04 sensor, for outputting liquid level data), a display driver circuit (for controlling the LCD), a button 5 input circuit (for receiving instructions), and an output control circuit (JQX-13F relay, for driving solenoid valve 3). The main control circuit integrates input and output to the LCD display and relay without requiring replacement circuits, ensuring seamless collaboration and high accuracy and efficiency.
