[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0027] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0028] like Figure 1 and Figure 4 As shown, the utility model provides a water flow monitoring and regulating device for a salt chlorine machine, comprising: a water pump 2 and a controller 3 arranged inside a salt chlorine machine housing 1, one end of the water pump 2 being connected to a water pipe 4; a monitoring component for monitoring the water flow of the water pipe 4; and a regulating component for regulating the water flow, the regulating component being electrically connected to the water pump 2 via the controller 3.

[0029] Two water pumps 2 for conveying tap water and saturated brine to the electrolytic cell of the salt chlorine machine are arranged inside the housing 1 of the salt chlorine machine. A water pipe 4 is arranged at the outlet of the water pump 2. The flow rate at the outlet of the water pump 2 is monitored by a monitoring component. The regulating component is used to adjust the voltage value, and then the working voltage of the water pump 2 is adjusted and outputted through the controller 3 accordingly. The working voltage can control the rotation speed of the water pump 2, so as to adjust the rotation speed of the water pump 2. The tap water or brine discharged from the outlet of the water pump 2 enters the water pipe 4 and is detected and displayed by the monitoring component. The controller 3 is set by a controller in the prior art.

[0030] Through the adjustment component and the controller 3, the working voltage of the water pump 2 can be adjusted, thereby controlling the rotation speed of the water pump 2 and adjusting the water flow in the water pipe 4; through the monitoring component, the water flow can be detected and displayed, and the flow of tap water and saturated salt water can be monitored and controlled, and the precise ratio of the two can be achieved, thereby improving the stability of the generated chlorine concentration.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the monitoring component includes: a water flow sensor 5 arranged inside the salt chlorine machine housing 1 and a display 6 arranged outside the salt chlorine machine housing 1, the water flow sensor 5 is arranged on the water pipe 4, and the water flow sensor 5 is electrically connected to the display 6.

[0032] Furthermore, the water flow sensor 5 is a Hall sensor.

[0033] The water flow sensor 5 is used to detect the water flow in the water pipe 4 in real time, and then convert the water flow into a pulse digital signal, display the flow data through the display 6, and then adjust it again through the adjustment component according to the displayed water flow size to adjust to the required water flow.

[0034] like Figure 2 As shown, in one embodiment, the regulating component is: a regulating control switch 7 arranged outside the salt chlorine machine housing 1, and the regulating control switch 7 is electrically connected to the water pump 2 through the controller 3.

[0035] The regulating control switch 7 is arranged below the display 6, and the switch and the speed of the water pump 2 can be controlled by the controller 3;

[0036] The regulating control switch 7 can be manually rotated to adjust the voltage value, so that the operating voltage of the water pump 2 is adjusted and output through the controller 3 .

[0037] Furthermore, the regulating control switch 7 includes: a fixing ring 710 arranged outside the salt chlorine machine housing 1, a knob 720 rotatably connected to the fixing ring 710, and a regulator 730 connected to the knob 720, and the regulator 730 is electrically connected to the controller 3.

[0038] The fixing ring 710 can be connected to the salt chlorine machine housing 1 by snap-fitting or screws, and the knob 720 is rotatably connected to the fixing ring 710. When the voltage is adjusted, while the knob 720 is rotated, the resistance value of the regulator 730 connected to the circuit will change, thereby realizing voltage regulation, and then the controller 730 will output the working voltage of the water pump 2 accordingly to adjust the working voltage of the water pump 2, thereby changing the rotation speed of the water pump 2 to achieve the purpose of regulating the water flow rate. The specific value of the water flow rate can be displayed on the display 6.

[0039] Furthermore, the regulator 730 is a potentiometer, or the regulator 730 is an adjustable resistor.

[0040] A potentiometer is a resistor element with three terminals and whose resistance value can be adjusted according to a certain law of change. A potentiometer is usually composed of a resistor body and a movable brush. When the brush moves along the resistor body, a resistance value or voltage that is related to the displacement is obtained at the output end.

[0041] The adjustable resistor mainly changes the resistance value by changing the length of the resistor connected to the circuit. It can gradually change the current in the electrical appliance connected in series with it, and it can also gradually change the voltage of the electrical appliance connected in series with it.

[0042] In this embodiment, the resistance of the regulator 730 changes with the rotation of the knob 720 .

[0043] like Figure 3 As shown, in one embodiment, a scale is provided on the surface of the fixing ring 710, and an indicator needle for indicating the scale position is provided on the surface of the knob 720.

[0044] When the knob 720 is rotated, the indicator needle rotates synchronously with the knob 720 , and the indicator needle can point to a corresponding scale, which may be a flow scale, that is, represents the magnitude of the water flow corresponding to the working voltage of the water pump 2 .

[0045] like Figure 5 As shown, in one embodiment, the adjustment component is: an automatic adjustment module;

[0046] The automatic adjustment module includes: an adjustment control switch 7 arranged outside the salt chlorine machine housing 1 and a driving unit capable of driving the adjustment control switch 7 to operate. The adjustment control switch 7 is electrically connected to the water pump 2 through the controller 3.

[0047] When the regulating component adopts an automatic regulating module, the controller 3 includes: a PID module and a DCS module electrically connected to the water pump 2, the regulating component and the monitoring component, and a processing module electrically connected to the monitoring component, and the processing module is electrically connected to the PID module and the DCS module.

[0048] Among them, the PID module is used to control and adjust the operating parameters of the water pump 2, the regulating component and the monitoring component, the DCS module is used to monitor the operating parameters of the water pump 2, the regulating component and the monitoring component, and the processing module is used to receive and process the signal of the water flow sensor 5 of the monitoring component;

[0049] Wherein, the regulating control switch 7 comprises: a fixing ring 710 arranged outside the salt chlorine machine housing 1, a knob 720 rotatably connected to the fixing ring 710, and a regulator 730 connected to the knob 720, wherein the regulator 730 is electrically connected to the controller 3; one end of the knob 720 connected to the regulator 730 is also provided with a driving part for driving the rotation thereof, and the driving part can be a micro motor, and the micro motor is electrically connected to both the PID module and the DCS module;

[0050] The controller 3 further includes a control module for controlling the rotation of the micro motor to adjust the regulator 730 .

[0051] At the initial moment of operation, the operator can first rotate the knob 720 to set the initial working voltage of the water pump 2. In theory, there will be a set water flow corresponding to the initial working voltage in the water pipe 4; but since the scale indicated by the indicator needle may have an error with the actual water flow, it is necessary to monitor the actual water flow to achieve automatic adjustment; the water flow sensor 5 will transmit the detected actual water flow to the processing module in real time. After the processing module receives and processes the actual water flow, it will be transmitted to the PID module and the DCS module. The PID module and the DCS module compare the actual water flow with the set water flow, and then control the micromotor of the automatic adjustment module to drive the knob 720 to rotate, thereby adjusting the resistance of the regulator 730, thereby controlling and adjusting the working voltage of the water pump 2 to ensure the accuracy of the actual water flow.

[0052] The PID module, DCS module, control module and processing module in the above scheme are all configured using system modules in the prior art;

[0053] For example, the PID module can use a PID controller (composed of a proportional unit P, an integral unit I and a differential unit D. The PID controller is mainly suitable for systems whose basic linearity and dynamic characteristics do not change over time) to compare the collected data with a reference value, and then use the difference to calculate a new input value. The purpose of this new input value is to allow the system data to reach or remain at the reference value; the DCS module is a distributed control system, which is based on a microprocessor and adopts the design principles of decentralized control functions, centralized display operations, and a combination of autonomy and comprehensive coordination. Distributed control system is referred to as DCS, which can also be directly translated as "distributed control system" or "distributed computer control system."

[0054] like Figure 6 and Figure 7As shown, in one embodiment, the regulator 730 includes: two fixed blocks 731 for connecting to the inner side of the salt chlorine machine housing 1, a resistor 732 is connected between the two fixed blocks 731, two power-connecting slides 733 electrically connected thereto are slidably provided on the resistor 732, a power-connecting slider 734 electrically connected thereto is provided on the power-connecting slider 733, a fixed rod 735 is further connected between the two fixed blocks 731, the power-connecting slider 734 is slidably connected to the fixed rod 735, a rack 736 is further connected to the power-connecting slider 734, and the two racks 736 are centrally symmetrically arranged; the knob 720 is provided with a connecting shaft 737 passing through the salt chlorine machine housing 1, and a gear 738 meshingly connected to the rack 736 is provided at the end of the connecting shaft 737;

[0055] The two power-connecting sliders 734 are electrically connected with wires, and the regulator 730 is electrically connected to the controller 3 via the wires.

[0056] The above is a solution when the regulator 730 uses an adjustable resistor. The resistor 732 is connected to the fixing member on the salt chlorine machine housing 1 through the fixing block 731. The resistor 732 can be fixed by screw connection or clamping.

[0057] The resistor 732, the power-connecting slide 733 and the power-connecting slider 734 are electrically connected in sequence, and a wire is arranged on the power-connecting slider 734, and the resistor 732 between the two power-connecting slides 733 is connected to the circuit through the wire;

[0058] When the knob 720 is rotated, the connecting shaft 737 and the gear 738 are driven to rotate synchronously, and the two racks 736 meshing with the gear 738 move synchronously, driving the two power-connecting sliders 734 to move away from or towards each other. When the two power-connecting sliders 734 move away from each other, the two power-connecting slides 733 move away from each other, and the length of the resistor 732 connected to the circuit becomes longer. When the two power-connecting sliders 734 move towards each other, the two power-connecting slides 733 move towards each other, and the length of the resistor 732 connected to the circuit becomes shorter, thereby achieving voltage regulation.

[0059] When the regulating component adopts an regulating control switch, that is, when the voltage is adjusted only by manual rotation control, the regulator 730 can adopt the above-mentioned technical solution; when the regulating component adopts an automatic regulating module, the regulator 730 is based on the above-mentioned technical solution, and a micro motor is installed on the inner side of the salt chlorine machine housing 1, and a driving gear is set at the output end of the micro motor, and a driven gear is set on the connecting shaft 737.

[0060] like Figure 1 and Figure 2 As shown, a salt chlorine machine includes the water flow monitoring and regulating device of the salt chlorine machine described in the utility model.

[0061] The salt chlorine machine adopts the water flow monitoring and regulating device described in the utility model, which can realize accurate control of water flow, achieve accurate proportioning of tap water and saturated salt water, and improve the stability of generated chlorine concentration.
