Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples of the invention do not represent all embodiments consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The technical scheme provided by the embodiment of the invention considers that after airflow (the following part is expressed by 'injection airflow') generated by injection action of spray droplets in the spraying process reaches a target area, the injection airflow moves around due to the obstruction of a target object in the target area, the continuously generated injection airflow enables the surrounding air to be continuously accelerated, the airflow strength around the spray droplets is continuously increased and generates turbulence, the corresponding airflow kinetic energy is continuously increased, the drifting action on the spray droplets is increasingly large, so that partial spray droplets fall off the target and drift along with the airflow, and the strength of the injection airflow is a key factor influencing the spray droplet deposition rate, therefore, the technical scheme provided by the embodiment of the invention obtains the corresponding spray amount and the corresponding spraying interval time by controlling the starting time and the stopping time of the power unit according to the factor, the fog body of intermittent spraying is generated, the intensity of ejection airflow is reduced by reducing the fog amount of single spraying, and the continuity of the ejection airflow generated by the movement of fog drops is greatly reduced by adopting an intermittent spraying mode, so that the airflow intensity is reduced, the drifting amount of the fog drops is greatly reduced, the deposition rate of the fog drops is improved, and the resource waste and the adverse effect of the fog drops after off-target on the environment are reduced.
As shown in fig. 1, an embodiment of the present invention provides a spraying system, which includes a power unit 01, a control unit 02; the power unit 01 is connected with the spraying pipeline 03 and used for conveying liquid to the spraying pipeline 03, and the conveyed liquid reaches the nozzle 04 through the spraying pipeline 03 and is sprayed out through the nozzle 04 to form mist.
The control unit 02 is configured to acquire a preset start-stop period, and control the power unit 01 to periodically deliver liquid to the nozzles 04 according to the start-stop period.
Specifically, as shown in fig. 2, the control unit 02 obtains a preset start-stop period S1, where the start-stop period S1 includes a start time S11 and a stop time S12, that is, within the start time S11, the control unit 01 controls the nozzle 04 to deliver liquid to form mist, where the mist is formed by a mist droplet group, a duration of the start time S11 determines a size of the mist or a quantity (mist quantity) of the mist, and the smaller the mist or the smaller the mist quantity, the larger the influence of air resistance is, the smaller the kinetic energy is generated, the lower the mist speed is, and therefore, the lower the air flow intensity generated by the injection is; the duration of the stop time S12 determines the degree of weakening of the air flow strength because the air flow generated by the mist sprayed during the start time reaches the target region, and the air flow strength is gradually weakened by the obstruction of the target object and the influence of air resistance, so that the air flow strength is gradually weakened after the mist stops being sprayed to the nozzle 04 during the stop time S12.
In summary, the control unit 02 correspondingly obtains the continuous and intermittent spray by controlling the power unit 01 to work according to the start-stop period S1, so as to greatly reduce the airflow strength generated by the spray injection effect and improve the spray deposition rate.
Illustratively, in an embodiment of the present invention, as shown in fig. 3 and 4, the main components of the power unit 01 may include: a pump 08 or a switching valve 09; for example, in the embodiment, the pump 08 may be embodied as a pump structure, such as a diaphragm pump, a plunger pump, but is not limited to the diaphragm pump and the plunger pump, and both the diaphragm pump and the plunger pump belong to a displacement pump; the switch valve 09 may be embodied as a controllable switch valve, such as but not limited to a solenoid valve and an electric valve.
Further, in the embodiment of the present invention, the control Unit may be a control circuit for controlling the pump or the switch valve, may be a control circuit including a Microcontroller (which shall be: a Microcontroller Unit, abbreviated as MCU), and may also be a cycle timing circuit including a 555 timer, but is not limited to these two circuit types.
It should be noted that the control unit may further include a component for selecting or inputting a start-stop period, such as a potentiometer, a button, a human-computer interaction interface, but not limited to the potentiometer, the button, and the human-computer interaction interface, for example, the control unit obtains a corresponding start-stop period by obtaining a current value or a voltage value of the potentiometer and performing analog-to-digital conversion; for example, the control unit may determine one of the groups as the current use start-stop period by selecting a preset set of start-stop period values, for example, by a button, or by increasing/decreasing the adjustment step length, and add the value determined to increase/decrease according to the corresponding step number to the initial value of the start-stop period to obtain the current use start-stop period; for another example, the control unit may directly receive a corresponding start-stop period input by a user through a human-computer interaction interface; further, the control unit may also receive the start-stop period sent by the network side through the receiving module.
Specifically, as shown in fig. 5, the response time of the power unit is related to the performance and parameters of the main components of the power unit, for example, when the main components of the power unit are a pump, that is, the pump directly drives the liquid to be pressurized and delivered to the nozzle, as is well known, the power unit of the pump is mainly a motor, and since the motor is an inductive load, it takes a certain time to reach a steady state, and the driving load is different, so that after a steady output power is reached, a steady liquid pressure is reached at the nozzle, thereby obtaining a sufficient atomization effect, for example, the minimum time from start to steady output of the pump used in the embodiment of the present invention is t1, and assuming that t1=150MS, the preset start time should be greater than 150 MS; it is understood that this is by way of illustration and not by way of limitation.
For another example, when the main control component of the power unit is a switch valve, as shown in fig. 4, the liquid in the liquid inlet pipe 10 is received at the liquid inlet end of the switch valve 09, and the liquid in the liquid inlet pipe 10 has a certain pressure, such as a tap water pipe network, or a liquid storage tank pressurized by gas or liquid, or a main pipeline or a branch pipeline in a centralized pressure supply system, or an output end pipeline of a pump which is not suitable for being started or stopped quickly; therefore, the liquid is periodically delivered to the nozzle 04 by controlling the on-off of the switch valve 09, and then the minimum on-time of the switch valve 09 determines the response time of the power unit with the structure, and it should be understood that the minimum on-time is the time required for the liquid pressure at the liquid inlet end and the liquid outlet end of the switch valve 09 to be consistent, and is not the response time of the switch valve itself, for example, the response time of a high-precision electromagnetic valve can reach 5 ms; for example, assuming that the minimum time from activation of the switching valve to the steady state of the liquid pressure is 20MS, the preset activation time should be greater than 20 MS; it is understood that this is by way of illustration and not by way of limitation.
In practice, the distances between the nozzle and the target object are different, so the starting time is not limited to the minimum starting time, because the smaller mist generates smaller kinetic energy, the kinetic energy is gradually exhausted due to the resistance of air friction after being sprayed, and the kinetic energy is naturally dropped under the action of gravity after being exhausted, then the naturally dropped mist drops can fall off the target even if the position of the nozzle is not located at the vertical position of the target object, or the mist drops need certain kinetic energy to reach the target area as soon as possible when the nozzle is far away from the target area, so the mist drops are prevented from being drifted under the influence of environmental air flow (small indoor air flow), therefore, it is necessary to obtain the proper mist through changing the starting time, and certainly, the starting time is controlled within a reasonable range, the size of the mist can be controlled according to the actual situation, the proper injection air flow strength is obtained, and the mist drop deposition rate is improved. To sum up, the start-up time in the start-stop cycle of the control unit according to the embodiment of the present invention is less than or equal to the minimum start-up time +550ms, for example, the start-up time range of the pump: the starting time is more than or equal to 150ms and less than or equal to 700 ms; start-up time range of the on-off valve: the starting time is more than or equal to 20ms and less than or equal to 570 ms; in order to make the start-stop cycle of the control unit more universal, the start time range provided by the invention is as follows: the starting time is more than or equal to 20ms and less than or equal to 700 ms.
It should be noted that, in practical use, the start time range of the most commonly used pump is 200ms or less and 500ms or less, but not limited to this range; the starting time range of the switch valve is not less than 50ms and not more than 350ms, but is not limited to the range; then, in order to simplify the adjustment range, the start-up time range provided by the present invention may also be: 50ms ≦ activation time ≦ 500ms, although this is merely illustrative and not the only limitation of the present invention.
Furthermore, after the sprayed mist reaches the target area, the air flow strength is gradually weakened due to the fact that the mist flows around under the obstruction of the target object and is influenced by air resistance, the weakening degree of the air flow strength is determined by the duration of the stopping time, and the preset range of the stopping time is 500 ms-2000 ms; the most common preset stop time range in practical use is 800ms to 1500ms, which is only illustrative and not limiting to the present invention.
It should be noted that the start time range and the stop time range provided above can be set according to actual needs, for example, the drift condition of the mist droplets can be observed, and an appropriate start time and stop time are set, and the control unit determines the start-stop period according to the start time and the stop time.
Optionally, in the embodiment of the present invention, the control unit obtains a preset working duration, and controls the power unit to operate according to the start-stop period within the working duration according to the working duration, so as to obtain a mist continuously and discontinuously sprayed within the preset working duration, so as to achieve the purpose of timing the spraying operation, for example, when the working duration is 30 seconds, the start-stop period is 300ms of start time, and the stop time is 1000 ms; within 30 seconds, then, 30000 ÷ 1300 ≈ 23 is obtained by calculation, i.e. 23 actuation cycles are performed within 30 seconds, which may also be understood as 23 mists within 30 seconds, each time a misting time of 300ms, each time an interval of 1000ms, although this is merely an example and is not a sole limitation of the present invention.
In summary, the spraying system provided by the embodiment of the invention controls the power unit to periodically work through the control unit according to the start-stop period to obtain the discontinuously sprayed mist, so that compared with a continuous spraying mode, the spraying system greatly reduces the strength of the injected airflow and improves the deposition rate of the droplets.
In the above description of the spraying system in the embodiment of the present invention, the following description of the spraying control method in the embodiment of the present invention:
as shown in fig. 6, the method is used in a spraying system or in a terminal device such as a mobile phone for controlling the operation of the spraying system or in an application program for controlling the operation of the spraying system, and includes:
s101, acquiring a preset start-stop period;
specifically, please refer to the embodiment provided in fig. 2 for a detailed description of the start-stop period, which is not repeated herein. Further, the start-stop period may be set by direct or indirect input, such as directly inputting a value setting of a corresponding start-stop period through a human-computer interface or receiving a value setting of a start-stop period sent from a network side; an indirect input mode, for example, a current value or a voltage value of the potentiometer is subjected to analog-to-digital conversion to obtain a corresponding start-stop period value, and the start-stop period value is used for setting; the start-stop period may also be set by a fixed value, for example, one or more groups of fixed start-stop period values are provided, and the start-stop period is set by selecting one of the start-stop period values, or for example, a preset start-stop period initial value and an adjustment step size are provided, where the increase/decrease adjustment step size may be to increase/decrease only the start time, or to increase/decrease only the stop time, or to increase/decrease the start time and the stop time according to a preset ratio, for example, the start-stop period initial value may be set to be the start time 100ms, the stop time 1100ms, and the preset adjustment step size is 30ms, then taking only the start time to increase as an example, then the adjusted start time may be understood as: 100+ n × 30, e.g., the start-up time after adding 2 adjustment steps is: 100+2 × 30=160ms, the start-stop cycle is the start time 160ms, and the stop time 1100 ms. It should be understood that the present invention is described by way of example only, and not by way of limitation, and the present invention may be practiced in other ways than those described above.
And S102, controlling the power unit to work periodically according to the start-stop period.
It can be understood that the periodic work of the power unit is controlled according to the acquired start-stop period to obtain corresponding mist quantity and spraying interval time, the intermittently sprayed mist is generated, the intensity of the injection airflow is reduced by reducing the mist quantity of single spraying, the continuity of the airflow generated by the movement of the mist drops is greatly reduced by means of intermittent spraying, so that the airflow intensity is reduced, the mist drop drift amount is greatly reduced, and the mist drop deposition rate is improved.
Further, as shown in fig. 7, in the spray control method provided in the embodiment of the present invention, S101 specifically includes:
s201, acquiring preset starting time, wherein the starting time ranges from 20ms to 700 ms;
it should be noted that, in practice, the distances between the nozzle and the target are different, and the starting time is not limited to the minimum starting time, which has been described in detail in the embodiments of the method, and will not be described herein again, because the smaller the kinetic energy of the mist is, after the kinetic energy is gradually exhausted due to the resistance of air friction after spraying, the kinetic energy is naturally dropped due to the effect of gravity, and then, if the position of the nozzle is not located at the vertical position of the target, the naturally dropped mist drops will also fall off the target, or if the nozzle is farther from the target area, the mist drops need a certain kinetic energy to reach the target area as soon as possible, and are prevented from being drifted due to the influence of the ambient air flow (smaller indoor air flow), and therefore, it is necessary to obtain a suitable mist by changing the starting time, of course, the starting time should be controlled within a reasonable range, the injection airflow strength can be controlled according to actual conditions, and the droplet deposition rate is improved. To sum up, the start-up time in the start-stop cycle of the control unit according to the embodiment of the present invention is less than or equal to the minimum start-up time +550ms, for example, the start-up time range of the pump: the starting time is more than or equal to 150ms and less than or equal to 700 ms; start-up time range of the on-off valve: the starting time is more than or equal to 20ms and less than or equal to 570 ms; in order to make the start-stop cycle of the control unit more universal, the start time range provided by the invention is as follows: the starting time is more than or equal to 20ms and less than or equal to 700 ms.
It should be noted that, in practical use, the start time range of the most commonly used pump is 200ms or less and 500ms or less, but not limited to this range; the starting time range of the switch valve is not less than 50ms and not more than 350ms, but is not limited to the range; in order to simplify the adjustment range and improve the versatility, the start-up time range provided by the present invention may also be: 50ms ≦ activation time ≦ 500ms, although this is merely illustrative and not the only limitation of the present invention.
S202, acquiring preset stop time, wherein the preset range of the stop time is 600 ms-2000 ms;
it should be noted that, after the sprayed mist reaches the target area, the air flow strength is gradually weakened due to the obstruction of the target object to flow around and the influence of the air resistance, so the duration of the stop time S12 determines the weakening degree of the air flow strength, and the preset range of the stop time provided by the invention is 500ms to 2000 ms; the most common preset stop time range in practical use is 800ms to 1500ms, which is only illustrative and not limiting to the present invention.
It should be noted that the setting method and the manner of the start-up time or the stop time are the same as the setting method of the start-up and stop period, please refer to the detailed description of step S101, and are not described herein again.
S203, determining the start-stop period according to the acquired start time and stop time.
It should be noted that the start time range and the stop time range provided above may be set according to actual needs, for example, the drift condition of the mist droplets may be observed, an appropriate start time and an appropriate stop time may be set, and the start-stop period may be determined according to the start time and the stop time.
Optionally, as shown in fig. 8, the spray control method provided in the embodiment of the present invention further includes:
s301, acquiring a preset working duration;
and S302, controlling the power unit to work according to the start-stop period in the working duration according to the working duration.
It should be noted that, in the embodiment of the present invention, by obtaining a preset working time length, and according to the working time length, controlling the power unit to work according to the start-stop period within the working time length, so as to obtain a mist continuously and discontinuously sprayed within the preset working time length, a purpose of timing a spraying operation is achieved, for example, when the working time length is 30 seconds, a start-stop period is 250ms, and a stop time is 1200 ms; within 30 seconds, this is then calculated to be 30000 ÷ 1450 ≈ 20, i.e. about 20 activation cycles are performed within 30 seconds, which may also be understood as 20 sprays within 30 seconds, each spraying time 250ms and each interval 1200ms, although this is only an illustration and not a sole limitation of the invention.
In summary, the spraying control method provided by the invention obtains the corresponding mist quantity and the corresponding spraying interval time by controlling the periodic work of the power unit, generates the intermittently sprayed mist, reduces the intensity of the generated air flow by reducing the mist quantity of single spraying, and greatly reduces the continuity of the air flow generated by the movement of the mist drops by means of intermittent spraying, thereby greatly reducing the drift amount of the mist drops and improving the deposition rate of the mist drops.
As shown in fig. 9, an embodiment of the present invention provides a spray control device, including:
the first obtaining module 111 is configured to obtain a preset start-stop period;
and the control module 112 is used for controlling the power unit to work periodically according to the start-stop period.

In summary, the spray control device provided by the invention generates intermittently-sprayed mist by controlling the periodic work of the power unit to obtain corresponding mist amount and spraying interval time, reduces the intensity of generated air flow by reducing the mist amount of single spraying, and greatly reduces the continuity of air flow generated by the movement of mist drops by means of intermittent spraying so as to reduce the intensity of air flow, thereby greatly reducing the drift amount of the mist drops and improving the deposition rate of the mist drops.
