[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-Figure 5 As shown, the utility model provides a pressure-regulated metering diaphragm pump device, comprising: a water pump 2 and a controller 3 arranged inside a salt chlorine machine housing 1, a regulating control switch 7 for regulating water flow, the regulating control switch 7 being electrically connected to the water pump 2 through the controller 3; a one-way valve 8 is provided at the water inlet of the water pump 2.

[0029] The controller 3 is set by using the controller in the prior art, the water pump 2 is an ordinary vacuum diaphragm pump, and two water pumps 2 for conveying tap water and saturated brine to the electrolytic cell of the salt chlorine machine are arranged inside the salt chlorine machine housing 1. The regulating control switch 7 is used to adjust the voltage value, and then the working voltage of the water pump 2 is adjusted and outputted by the controller 3 accordingly. The working voltage can control the speed of the water pump 2, so as to adjust the speed of the water pump 2; the original metering pump is changed from the frequency and speed metering method to the pressure regulating method to change the speed metering method of the vacuum diaphragm pump;

[0030] In order to prevent the water flow in the vacuum diaphragm pump from flowing back, a one-way valve 8 is installed at the water inlet of the water pump 2. The one-way valve 8 can prevent the water from flowing back after the water pump 2 stops working, that is, prevent the water from flowing out of the water inlet of the water pump 2.

[0031] Through the above scheme, a vacuum diaphragm pump and an adjusting control switch 7 can be used to adjust the water flow of the water pump 2 by adjusting the voltage, replacing the original method of adjusting the water flow by the metering pump, thereby saving costs; the water backflow can be controlled by the one-way valve 8 to prevent the water from flowing out of the water inlet, thereby achieving the purpose of accurately mixing tap water and saturated salt water.

[0032] like Figure 1 As shown, in one embodiment, a water pipe 4 is connected to the water outlet of the water pump 2 , and a water flow sensor 5 is provided on the water pipe 4 .

[0033] Furthermore, it also includes: a display 6 arranged outside the salt chlorine machine housing 1, and the water flow sensors 5 are electrically connected to the display 6 respectively.

[0034] Furthermore, the water flow sensor 5 is a Hall sensor.

[0035] The tap water or salt water discharged from the outlet of the water pump 2 enters the water pipe 4, the water flow is detected by the water flow sensor 5, and then the water flow is converted into a pulse digital signal. The flow data is displayed on the display 6, so that the operator can observe the water flow more intuitively.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, the adjustment control switch 7 includes: a fixed ring 710 arranged outside the salt chlorine machine housing 1, a knob 720 rotatably connected to the fixed ring 710, and a regulator 730 connected to the knob 720, and the regulator 730 is electrically connected to the controller 3.

[0037] The adjustment control switch 7 is set below the display 6, and the adjustment control switch 7 can control the switch and speed of the water pump 2; the adjustment control switch 7 can be manually rotated to adjust the voltage value, so as to adjust and output the working voltage of the water pump 2 through 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] In one embodiment, the regulator 730 is a potentiometer or 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 2 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 3 and Figure 4 As shown, in one embodiment, the regulator 730 includes: a resistor body arranged on the inner side of the salt chlorine machine housing 1, a driving member is provided on the resistor body, and a connecting shaft 737 is provided on the knob 720 and passes through the salt chlorine machine housing 1, and the end of the connecting shaft 737 away from the knob 720 is connected to the driving member.

[0046] Furthermore, the resistor body includes: a resistor 732, both ends of which are provided with fixed blocks 731, and the fixed blocks 731 are connected to the fixing parts on the salt chlorine machine housing 1; the resistor 732 is slidably provided with two power-connecting slides 733 electrically connected to it, and the power-connecting slide 733 is provided with a power-connecting slider 734 electrically connected to it.

[0047] Furthermore, the driving member includes: a fixed rod 735 arranged between two fixed blocks 731, the power-connecting slider 734 is slidably connected to the fixed rod 735, and the two power-connecting sliders 734 are respectively provided with racks 736, and the two racks 736 are arranged symmetrically with the center; the end of the connecting shaft 737 away from the knob 720 is provided with a gear 738 meshing with the two racks 736.

[0048] Furthermore, the two power-connecting sliders 734 are both provided with wires, and the regulator 730 is electrically connected to the controller 3 via the wires.

[0049] In the above technical solution, the resistor 732 is connected to the fixing member on the salt chlorine machine housing 1 through the fixing block 731, and the resistor 732 can be fixed by screw connection or clamping;

[0050] 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;

[0051] 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.

[0052] like Figure 5-Figure 7 As shown, in one embodiment, the one-way valve 8 includes: a valve body 810, wherein two ends of the valve body are respectively provided with a water inlet hole 811 and a water outlet hole 812, wherein the water outlet hole 812 is connected to the water inlet of the water pump 2; a movable cylinder body 820 is provided inside the valve body 810, wherein the end of the movable cylinder body 820 close to the water inlet hole 811 is a closed end, and the end close to the water outlet hole 812 is an open end, and an elastic member 840 is provided inside the movable cylinder body 820, wherein one end of the elastic member 840 is connected to the closed end of the movable cylinder body 820, and the other end is connected to the side wall of the valve body 810 where the water outlet hole 812 is located; and a through hole 821 is provided on the side wall of the movable cylinder body 820.

[0053] Furthermore, a sealing ring 830 is provided on the side wall where the water inlet hole 811 of the valve body 810 is located.

[0054] A valve cavity is provided in the valve body 810, and a movable cylinder 820 is arranged in the valve cavity. One end of the movable cylinder 820 close to the water inlet hole 811 is tapered, and a gap is formed between the tapered shape and the valve cavity.

[0055] After the water pump 2 is working, water flows in from the water inlet hole 811 of the one-way valve 8. Under the push of the water pressure, the closed end of the movable cylinder 820 is pushed to move toward the water outlet hole 812, thereby compressing the elastic member 840, and the closed end of the movable cylinder 820 is separated from the sealing ring 830. The water flows in from the gap formed after the separation, and then enters the inside of the movable cylinder 820 from the through hole 821 of the movable cylinder 820, and finally flows out from the water outlet hole 812.

[0056] After the water pump 2 stops working, the closed end of the movable cylinder 820 loses the thrust of the water pressure, and the movable cylinder 820 is pushed to the side of the water inlet hole 811 under the elastic recovery force of the elastic member 840, so that its closed end is sealed against the sealing ring 830 to achieve sealing. In this way, after the water pump 2 stops working, the water flow will not flow back, ensuring the accurate ratio of tap water and saturated salt water.
