Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.

[0034] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0035] Figure 1 is a flow chart of a cleaning liquid flow control method provided by the embodiment of the present application, the embodiment can be applicable to the case of accurately controlling the cleaning liquid flow; the method can be executed by a cleaning liquid flow control device, as shown in Figure 1 The design method specifically includes the following steps:

[0036] S110, determining the clean water flow according to the water jet pump power duty cycle.

[0037] The water jet pump power duty cycle is the ratio between the power of the water jet pump in the on state and the rated power; the size can be any value in 0-100%; it can be understood that the greater the water jet pump power duty cycle, the greater the output power; the smaller the water jet pump power duty cycle, the smaller the output power; when the output power is large, the speed of the water jet pump is large, and the output clean water flow is large; when the output power is small, the speed of the water jet pump is small, and the output clean water flow is small; that is, there is a certain mapping relationship between the water jet pump power duty cycle and the clean water flow;

[0038] The embodiment can determine the actual clean water flow according to the size of the water jet pump power duty cycle based on the mapping relationship between the water jet pump power duty cycle and the clean water flow.

[0039] S120, determining the cleaning liquid flow rate according to the fresh water flow rate and the set concentration.

[0040] The current fresh water flow rate can be monitored in real time by a flow meter on the fresh water pipeline, and the cleaning liquid flow rate can be determined based on the proportional relationship between the fresh water flow rate, the set concentration and the cleaning liquid flow rate. Thus, the set concentration of the cleaning liquid is ensured to be constant. Specifically, the proportional relationship between the fresh water flow rate, the set concentration and the cleaning liquid flow rate is: cleaning liquid flow rate = fresh water flow rate x set concentration / (1-set concentration).

[0041] The cleaning liquid flow rate in the embodiment is the target cleaning liquid flow rate determined according to the set concentration, and the actual cleaning liquid flow rate output often has a certain deviation from the target cleaning liquid flow rate. When the actual cleaning liquid flow rate has a small deviation from the target cleaning liquid flow rate, the cleaning liquid flow rate output precision meets the requirements. When the actual cleaning liquid flow rate has a large deviation from the target cleaning liquid flow rate, the cleaning liquid flow rate output precision does not meet the requirements.

[0042] S130, outputting a power duty cycle signal according to the cleaning liquid flow rate, or outputting a power duty cycle signal and a time duty cycle signal to the cleaning liquid pump body.

[0043] Generally, the power duty cycle signal is linearly output according to the cleaning liquid flow rate. Since the cleaning liquid pump body itself has a highest efficiency zone (BEP), which is usually located near the rated flow rate. When the flow rate is lower than the highest efficiency zone (BEP), the leakage (backflow) loss, disc friction loss and other losses inside the cleaning liquid pump will dominate. Thus, when the cleaning liquid flow rate is small, the corresponding power duty cycle is low. If the output power is small at this time, a large part of it is used to overcome the internal losses of the cleaning liquid pump rather than to transport fluid, resulting in a large deviation between the actual output flow rate and the theoretical calculation value, and leading to poor flow rate control precision.

[0044] The power duty cycle signal is output according to the cleaning liquid flow rate, or the power duty cycle signal and the time duty cycle signal are output to the cleaning liquid pump body. Specifically, when the cleaning liquid flow rate is in the low flow rate zone, the power duty cycle signal and the time duty cycle signal are output; when the cleaning liquid flow rate is not in the low flow rate zone, the power duty cycle signal is output. Thus, by intervening the time duty cycle signal on the basis of the power duty cycle signal, the problem of insufficient control precision in the low flow rate zone caused by directly outputting the power duty cycle signal according to the cleaning liquid flow rate can be avoided, so as to ensure the control precision of the cleaning liquid flow rate output in the low flow rate zone and other flow rate zones. The time duty cycle signal is the opening time proportion of the cleaning liquid pump body in a certain period.

[0045] The embodiment of the present application determines the clean water flow according to the water jet pump power duty cycle, determines the cleaning liquid flow according to the clean water flow and the set concentration, and outputs the power duty cycle signal or the power duty cycle signal and the time duty cycle signal to the cleaning liquid pump body according to the cleaning liquid flow size, so that the control method combining the power duty cycle signal and the time duty cycle signal can ensure the accuracy of the cleaning liquid flow at each cleaning liquid flow size, and the problem of insufficient control accuracy caused by using a single PWM signal to control the power duty cycle of the pump is avoided.

[0046] Optionally, based on the above embodiment, further refinement is made, Figure 2 is a flow chart of another cleaning liquid flow control method provided by the embodiment of the present application, as shown in the figure, the cleaning liquid flow control method comprises the following steps: Figure 2

[0047] S210, determining the clean water flow according to the water jet pump power duty cycle.

[0048] S220, determining the cleaning liquid flow according to the clean water flow and the set concentration.

[0049] S230, when the cleaning liquid flow size is in the first interval range, outputting the first power duty cycle value signal and the time duty cycle range signal to the cleaning liquid pump body.

[0050] The first interval range is a low flow interval range; for example, 0.4-10ml / min; the first power duty cycle value signal is a signal greater than the average power duty cycle value signal linearly output according to the lower cleaning liquid flow size in the prior art; for example, 40%; the first power duty cycle value signal is set to be greater than the average power duty cycle value signal linearly output according to the lower cleaning liquid flow size, so that the output flow can be greater than the lower cleaning liquid flow size; the time duty cycle range signal can be a signal setting different opening time in a certain period of time; it can also be a signal setting the same opening time in different periods of time; when the cleaning liquid flow size is the lower cleaning liquid flow size, the time duty cycle signal in the time duty cycle range signal is output on the basis of the first power duty cycle value signal, so that the output flow greater than the lower cleaning liquid flow can be controlled to be the lower cleaning liquid flow; thus the output accuracy of the lower cleaning liquid flow is ensured.

[0051] ​Similarly, when the cleaning liquid flow size is in the first interval range, a first power duty cycle value signal is outputted, so that the flow output exceeds the first interval range; on the basis of outputting the first power duty cycle value signal, a time duty cycle range signal is outputted to the cleaning liquid pump body, so that the cleaning liquid flow size remains in the first interval range. For details, refer to Table 1 below. Table 1 is a signal output table corresponding to different cleaning liquid flow sizes.

[0052]

[0053] S240, when the cleaning liquid flow size is in the second interval range, a second power duty cycle value signal is outputted to the cleaning liquid pump body.

[0054] The second interval range is a medium flow interval range. For example, 10-15 ml / min.

[0055] The second power duty cycle value signal is an average power duty cycle value signal outputted linearly according to the medium flow size in the prior art. The second power duty cycle value signal is smaller than the first power duty cycle value signal. For example, the second power duty cycle value signal is 30% (see Table 1). Thus, when the cleaning liquid flow size is in the second interval range, the second power duty cycle value signal is directly outputted to the cleaning liquid pump body, so that the cleaning liquid pump body outputs the cleaning liquid flow in the second interval range, and the output precision of the cleaning liquid flow in the second interval range is ensured.

[0056] S250, when the cleaning liquid flow size is in the third interval range, a third power duty cycle range signal is outputted to the cleaning liquid pump body.

[0057] The third interval range is a high flow interval range. For example, 20-65 ml / min. The third power duty cycle range signal is each power duty cycle value signal outputted linearly according to the high flow size in the prior art. The duty cycle value in the third power duty cycle range signal is greater than the second power duty cycle value signal (see Table 1). Thus, when the cleaning liquid flow size is in the third interval range, the third power duty cycle range signal is directly outputted to the cleaning liquid pump body, so that the cleaning liquid pump body outputs the cleaning liquid flow in the third interval range, and the output precision of the cleaning liquid flow in the third interval range is ensured.

[0058] The embodiment of the present application determines the clean water flow according to the water jet pump power duty cycle, determines the cleaning liquid flow according to the clean water flow and the set concentration, and outputs different control modes according to the cleaning liquid flow in different interval ranges, so that the cleaning liquid flow accuracy can be ensured under different cleaning liquid flow sizes, and the problem of insufficient control accuracy caused by using a single PWM signal to control the power duty cycle of the pump is avoided.

[0059] Optionally, based on the above embodiment, further refinement is made, Figure 3 is a flow chart of another cleaning liquid flow control method provided by the embodiment of the present application, as shown in the figure, the cleaning liquid flow control method comprises the following steps: Figure 3

[0060] S310, determining the clean water flow according to the water jet pump power duty cycle.

[0061] S320, determining the cleaning liquid flow according to the clean water flow and the set concentration.

[0062] S330, when the cleaning liquid flow size is in the first interval range, outputting the first power duty cycle value signal and the time duty cycle range signal to the cleaning liquid pump body; wherein the time duty cycle value in the time duty cycle range signal is related to the cleaning liquid flow value in the first interval range.

[0063] Specifically, the time duty cycle value in the time duty cycle range signal and the cleaning liquid flow value in the first interval range can be that the time duty cycle value size in the time duty cycle range signal gradually changes with the time duty cycle value in the time duty cycle range signal, or exponentially changes.

[0064] In some embodiments, the time duty cycle value in the time duty cycle range signal and the cleaning liquid flow value in the first interval range are positively correlated; for example, 0.4 ml / min corresponds to the minimum time duty cycle in the time duty cycle range signal, 10 ml / min corresponds to the maximum time duty cycle in the time duty cycle range signal, and 5.2 ml / min corresponds to the intermediate time duty cycle in the time duty cycle range signal; in this way, the time duty cycle value in the time duty cycle range signal and the cleaning liquid flow value in the first interval range are positively correlated, so that the output accuracy of the flow in the first interval range can be accurately controlled.

[0065] S340, when the cleaning liquid flow size is in the second interval range, outputting the second power duty cycle value signal to the cleaning liquid pump body.

[0066] ​S350. When the cleaning fluid flow rate is within the third interval range, output the third power duty cycle range signal to the cleaning fluid pump body; wherein, the power duty cycle within the third power duty cycle range signal is related to the cleaning fluid flow rate within the third interval range.

[0067] Among them, the power duty cycle within the third power duty cycle range signal is related to the cleaning fluid flow rate within the third interval range, that is, the power duty cycle within the third power duty cycle range signal changes gradually or exponentially with the cleaning fluid flow rate within the third interval range.

[0068] In some embodiments, the power duty cycle within the third power duty cycle range signal is positively correlated with the cleaning fluid flow rate within the third interval range. For example, 20 ml / min corresponds to a minimum power duty cycle of 40% within the third power duty cycle range signal; 65 ml / min corresponds to a maximum power duty cycle of 100% within the third power duty cycle range signal; and 37.5 ml / min corresponds to a maximum power duty cycle of 70% within the third power duty cycle range signal. Thus, the power duty cycle within the third power duty cycle range signal is positively correlated with the cleaning fluid flow rate within the third interval range, which allows for precise control of the output accuracy of the flow rate within the third interval range.

[0069] S360 outputs a control signal to the electro-proportional valve based on the flow rate of the cleaning fluid.

[0070] In order to achieve higher output accuracy based on the dual control methods of output power duty cycle and time duty cycle, this embodiment can also output an adjustment control signal to the electro-proportional valve according to the cleaning fluid flow rate (that is, further adjust the opening of the electro-proportional valve based on the original control of the opening of the electro-proportional valve). In this way, the output accuracy of the cleaning fluid flow rate can be further adjusted by the opening of the electro-proportional valve.

[0071] In this embodiment of the invention, the clean water flow rate is determined based on the power duty cycle of the water pump; the cleaning fluid flow rate is determined based on the clean water flow rate and a set concentration; and different control methods are output according to the cleaning fluid flow rate within different ranges. At the same time, an adjustment control signal is output to the electro-proportional valve according to the cleaning fluid flow rate. This further improves the accuracy of the cleaning fluid flow rate under various cleaning fluid flow rates, avoiding the problem of insufficient control accuracy caused by using a single PWM signal to control the pump power duty cycle.

[0072] This invention also provides a cleaning fluid flow control device, which can execute the cleaning fluid flow control method provided in any embodiment of this invention, and has the corresponding functional modules and beneficial effects of the method.

[0076] Optionally, the output module 30 includes:

[0077] The first output unit is used to output a first power duty cycle value signal and a time duty cycle range signal to the cleaning fluid pump body when the cleaning fluid flow rate is within the first interval range.

[0078] The second output unit is used to output a second power duty cycle signal to the cleaning fluid pump body when the cleaning fluid flow rate is within the second range; wherein the second power duty cycle signal is less than the first power duty cycle signal.

[0079] The third output unit is used to output a third power duty cycle range signal to the cleaning fluid pump body when the cleaning fluid flow rate is within the third interval range; wherein the duty cycle value within the third power duty cycle range signal is greater than the second power duty cycle value signal.

[0080] Optionally, the first output unit is specifically used to output a first power duty cycle value signal and a time duty cycle range signal to the cleaning fluid pump body when the cleaning fluid flow rate is within a first interval range; wherein, the time duty cycle value within the time duty cycle range signal follows the change of the cleaning fluid flow rate value within the first interval range.

[0081] Optionally, a third output unit is specifically used to output a third power duty cycle range signal to the cleaning fluid pump body when the cleaning fluid flow rate is within the third interval range; the power duty cycle within the third power duty cycle range signal is related to the cleaning fluid flow rate within the third interval range.

[0082] Optionally, the time duty cycle value within the time duty cycle range signal is positively correlated with the cleaning fluid flow rate value within the first interval range.
