[0001] The present application relates to the technical field of spraying devices, and particularly to a spraying device, a control method for the spraying device, and a computer storage medium. Background Art

[0002] In recent years, precise and intelligent spraying devices have been widely used. There are mainly two traditional spraying methods: one is to dig open the area to be sprayed in advance, lay corresponding pipes inside the area to be sprayed, and arrange multiple nozzles to cover the entire area to be sprayed. Although this method is beautiful and highly automated, it is complex to install and costly; the other is to attach nozzles to traditional water pipes to spray the area to be sprayed, but the spraying area of this method is limited, and the water pipes and nozzles need to be frequently moved, resulting in low spraying efficiency for the area to be sprayed. Therefore, there is an urgent need to develop a new implementation method to avoid the above problems and ensure that the spraying device can spray the area to be sprayed efficiently and intelligently. Summary of the Invention

Among them, the liquid container is used to store the liquid to be sprayed; the first pipe is connected to the nozzle, and the first pipe is used to guide the external water source to the nozzle; one end of the second pipe is connected to the liquid container, and the other end is connected to the first pipe. The second pipe is used to suck the liquid to be sprayed in the liquid container into the first pipe; the nozzle is used to spray the water flow in the first pipe onto the area to be sprayed; the controller can adjust the liquid flow rate or liquid pressure in the first pipe; among them, the controller can control the liquid flow rate or liquid pressure in the second pipe based on the liquid flow rate or liquid pressure in the first pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] The present application provides a spraying device 10, and the spraying device 10 of the present application can be applied to various areas to be sprayed such as grasslands, vegetation, gardens, etc. Figure 1 FIG. shows a schematic diagram of the overall structure of the spraying device 10 according to the present application. Figure 2 FIG. shows a cross-sectional schematic diagram of the internal structure of the spraying device 10 according to the present application. The following will be combined with Figure 1 and Figure 2 to describe the spraying device 10 of the present application in detail.

[0027] The spraying device 10 includes: a liquid container 101, a first pipeline 102, a second pipeline 103, a nozzle 104, and a controller 105. Among them, the liquid container 101 is used to store the liquid to be sprayed; the first pipeline 102 is connected to the nozzle 104, and the first pipeline 102 is used to guide the external water source to the nozzle 104; one end of the second pipeline 103 is connected to the liquid container 101, and the other end is connected to the first pipeline 102. The second pipeline 103 is used to suck the liquid to be sprayed in the liquid container 101 into the first pipeline 102; the nozzle 104 is used to spray the water flow in the first pipeline 102 onto the area to be sprayed; the controller 105 can adjust the liquid flow rate or liquid pressure in the first pipeline 102; among them, the controller 105 can control the liquid flow rate or liquid pressure in the second pipeline 103 based on the liquid flow rate or liquid pressure in the first pipeline 102.

[0028] For example, as shown in Figure 1 and Figure 2 , the spraying device 10 includes a liquid container 101, a first pipeline 102, a second pipeline 103, a nozzle 104, a controller 105 and other components. And the spraying device 10 is generally in a vertical structure. However, the spraying device provided by the present application is not limited to such a vertical structure.

[0029] The liquid container 101 is used to store the liquid to be sprayed. For example, it can be a liquid medicine, a nutrient solution, an insecticide, or a fertilizer suitable for the area to be sprayed, etc., and can provide functions such as preventing and controlling pests and diseases, supplementing nutrients, regulating the environment, or enhancing stress resistance for the area to be sprayed. The liquid container 101 can be presented in various different shapes, such as cylindrical or square-columnar, as long as it can be accommodated within the housing of the spraying device 10.

[0030] The first pipeline 102 can connect an external water source to the nozzle 104 and can guide the external water source to the nozzle 104. Among them, the arrow in the first pipeline 102 represents the direction of the water flow. The first pipeline 102 can be formed of plastic or alloy materials. The first pipeline 102 can have a certain degree of flexibility to facilitate the user to move the spraying device 10. It should be noted that Figure 2 The arrangement and orientation of the first pipeline 102 shown in [the figure] are only exemplary.

[0031] One end of the second pipeline 103 is connected to the liquid container 101, and the other end is connected to the first pipeline 102. It is used to suck the liquid to be sprayed in the liquid container 101 into the first pipeline 102 to achieve the mixing of the two liquids. Among them, the arrow in the second pipeline 103 represents the flow direction of the liquid to be sprayed. The second pipeline 103 can be formed of plastic or alloy materials. It should be noted that Figure 2 The arrangement and orientation of the second pipeline 103 shown in [the figure] are only exemplary.

[0032] The nozzle 104 is installed at the end or near the end of the first pipeline 102 and is used to spray the water flow in the first pipeline 102 or the liquid after the water flow is mixed with the liquid to be sprayed onto the area to be sprayed. The nozzle 104 can have a certain angle so as to obtain a certain spraying angle when spraying the water flow or liquid in the first pipeline 102.

[0033] The controller 105 is the core control component of the spraying device 10. It can adjust the liquid flow rate or liquid pressure in the first pipeline 102 and can control the liquid flow rate or liquid pressure in the second pipeline 103 based on the liquid flow rate or liquid pressure in the first pipeline 102.

[0034] Specifically, the first pipeline 102 is the main channel for guiding the external water source to the nozzle 104. By adjusting the liquid flow rate or liquid pressure in the first pipeline 102, the controller 105 can control the spraying intensity and spraying range of the water flow. For example, the controller 105 can increase the liquid flow rate or liquid pressure in the first pipeline 102 to make the water flow stronger, thereby expanding the spraying range of the area to be sprayed. The liquid to be sprayed in the liquid container 101 can be suctioned into the first pipeline 102 through the second pipeline 103 and mixed with the water flow in the first pipeline 102. The liquid in the second pipeline 103 needs to match the water flow in the first pipeline 102 to ensure that the spraying of the mixed liquid on the area to be sprayed meets the spraying purpose (for example, the liquid medicine concentration meets the expected concentration).

[0035] For example, if the liquid flow rate in the first pipeline 102 increases, the controller 105 will correspondingly increase the liquid flow rate in the second pipeline 103 to ensure that the two liquids can be mixed in a suitable proportion. For example, if the liquid flow rate in the first pipeline 102 doubles while the liquid flow rate in the second pipeline 103 remains unchanged, the proportion of the liquid to be sprayed in the mixed liquid will decrease, which may cause the spraying on the area to be sprayed to fail to achieve the expected effect. Therefore, the controller 105 needs to dynamically adjust the liquid flow rate in the second pipeline 103 according to the liquid flow rate in the first pipeline 102 to keep the mixing ratio in line with the expectation. Similarly, if the liquid pressure in the first pipeline 102 changes, the controller 105 will also adjust the liquid pressure in the second pipeline 103. For example, if the liquid pressure in the first pipeline 102 increases while the liquid pressure in the second pipeline 103 is not adjusted accordingly, it may cause the liquid to be sprayed in the second pipeline 103 to fail to enter the first pipeline 102 smoothly, or the mixed liquid to be uneven. Therefore, the controller 105 needs to accurately control the liquid pressure in the second pipeline 103 based on the liquid pressure in the first pipeline 102 to ensure that the two liquids can be mixed smoothly and sprayed evenly on the area to be sprayed.

[0036] The controller 105 includes a microcontroller 1051 and a first valve 1052. The microcontroller 1051 can control the opening degree of the first valve 1052, thereby controlling the liquid flow rate or liquid pressure in the first pipeline 102.

[0037] As Figure 2 shown, the microcontroller 1051, as the core component of the controller 105, is a miniaturized computer chip with functions such as data processing, logical judgment, and instruction output. It can receive externally input signals (such as spraying parameters set by users, environmental information detected by sensors, etc.) and process and analyze them according to a preset program to output corresponding control instructions.

[0038] The first valve 1052 is used to regulate the liquid flow rate or liquid pressure in the first pipeline 102. In other words, the opening degree of the first valve 1052 affects the throughput and pressure of the liquid in the first pipeline 102. Specifically, the microcontroller 1051 can calculate an appropriate valve opening based on preset spraying requirements (such as spraying range, spraying intensity, or spraying frequency, etc.) and information such as the real-time monitored liquid flow rate or liquid pressure in the first pipeline 102, and send corresponding control instructions to the first valve 1052. After receiving the instruction from the microcontroller 1051, the first valve 1052 can adjust its opening degree. The larger the valve opening of the first valve 1052, the greater the liquid flow rate in the first pipeline 102, and the relatively smaller the liquid pressure; the smaller the valve opening of the first valve 1052, the smaller the liquid flow rate in the first pipeline 102, and the relatively larger the liquid pressure. In this way, the microcontroller 1051 can accurately control the liquid flow rate or liquid pressure in the first pipeline 102, thereby achieving precise control of the area to be sprayed.

[0039] The other end of the second pipeline 103 is located downstream of the first valve 1052.

[0040] For example, as Figure 2 shown, the upstream of the first valve 1052 refers to the pipeline part before the liquid flows through the first valve 1052, and the downstream of the first valve 1052 refers to the pipeline part after the liquid flows through the first valve 1052. The part where the second pipeline 103 is connected to the first pipeline 102 is located after the water flow direction of the first valve 1052, that is, the other end of the second pipeline 103 is located downstream of the first valve 1052. Specifically, one end of the second pipeline 103 is connected to the liquid container 101, and the other end is connected to the first pipeline 102. The external water source can enter the interior of the spraying device 10 through the first pipeline 102 and flow to the nozzle 104 through the first valve 1052. Installing the other end of the second pipeline 103 downstream of the first valve 1052 can enable the liquid to be sprayed in the liquid container 101 to be injected into the first pipeline 102 through the second pipeline 103. In other words, after the liquid to be sprayed in the second pipeline 103 is mixed with the liquid in the first pipeline 102 (such as the external water flow), it will continue to flow along the first pipeline 102 (such as the direction indicated by the arrow in the first pipeline 102) to the nozzle 104. At the same time, when the first valve 1052 is in the closed state, the downstream of the first valve 1052 is a relatively closed area, which can prevent the liquid to be sprayed in the liquid container 101 from being affected by changes in the upstream liquid pressure or liquid flow rate, etc., thereby avoiding the possibility of liquid backflow.

[0041] The second pipeline 103 may include a power pump 1031, and the power pump 1031 is configured to provide a suction force for the second pipeline 103, and the liquid flow rate or liquid pressure in the second pipeline 103 is controlled by the power pump 1031.

[0042] For example, as Figure 2 shown, the power pump 1031 can provide a suction force for the second pipeline 103, so as to suck the liquid to be sprayed in the liquid container 101 into the second pipeline 103, and further transport it to the first pipeline 102, so that the liquid to be sprayed in the second pipeline 103 is mixed with the liquid (for example, external water flow) in the first pipeline 102. Specifically, the power pump 1031 generates a negative pressure through internal mechanical movement (for example, the rotation of an impeller driven by an electric motor), so that a suction force is formed inside the second pipeline 103, which can overcome the pressure difference between the liquid to be sprayed in the liquid container 101 and the second pipeline 103, and suck out the liquid to be sprayed in the liquid container 101. For example, when the power pump 1031 is started, the power pump 1031 can generate a low-pressure area at the inlet of the power pump 1031 through the rotation of the impeller, so that the liquid to be sprayed in the liquid container 101 is sucked into the second pipeline 103 under the action of the atmospheric pressure. The power pump 1031 can also pressurize the liquid. For example, when the liquid to be sprayed in the liquid container 101 passes through the power pump 1031, the power pump 1031 will pressurize the liquid to be sprayed, so that the liquid to be sprayed can overcome the resistance in the second pipeline 103 and flow smoothly in the second pipeline 103.

[0043] The second pipeline 103 may include a power pump 1031 and a second valve. The power pump 1031 is configured to provide a suction force for the second pipeline 103, and the second valve is configured to adjust the liquid flow rate or liquid pressure in the second pipeline 103.

[0044] For example, as Figure 2As shown, during the spraying process of the area to be sprayed by the spraying device 10, the power pump 1031 of the second pipeline 103 can cooperate with a second valve (not shown in the figure) to achieve the suction, transportation, and precise control of the liquid to be sprayed in the liquid container 101. The principle of the power pump 1031 has been described above and will not be elaborated here. The second valve is another key component installed on the second pipeline 103 and is used to adjust the liquid flow rate or liquid pressure in the second pipeline 103. The second valve can control the liquid flow rate in the second pipeline 103 by changing the valve opening degree, that is, the larger the valve opening degree of the second valve, the greater the liquid flow rate in the second pipeline 103. The second valve can also control the liquid pressure in the second pipeline 103 by changing the valve opening degree. When the valve opening degree of the second valve is small, the liquid will encounter a greater resistance when passing through the second valve, resulting in an increase in liquid pressure; when the valve opening degree of the second valve is large, the resistance of the liquid when passing through the second valve is small, resulting in a relatively lower liquid pressure. By adjusting the rotation speed of the power pump 1031 and the opening degree of the second valve, the liquid flow rate or liquid pressure in the second pipeline 103 can be precisely controlled, thereby achieving precise control of the area to be sprayed. For example, when it is necessary to spray a higher concentration of liquid medicine on the area to be sprayed, the rotation speed of the power pump 1031 can be increased and the valve opening degree of the second valve can be increased to increase the delivery volume of the liquid medicine per unit time.

[0045] The first valve 1052 and / or the second valve is an electrically controlled valve and is electrically connected to the controller 105.

[0046] For example, as Figure 2 shown, an electrically controlled valve is a device that controls the valve opening degree through an electrical signal. The electrically controlled valve is electrically connected to the controller 105 through an electrical circuit. Specifically, the controller 105 can control the valve opening degree by outputting a specific electrical signal (for example, a voltage signal, a current signal, etc.). For example, the controller 105 can output an analog signal, and its voltage value or current value is proportional or inversely proportional to the valve opening degree; or the controller 105 can output a pulse signal to control the valve opening degree through the frequency or duty cycle of the pulse. The electrically controlled valve can be equipped with a feedback device (for example, a position sensor or a pressure sensor, etc.) to improve the control accuracy. The feedback device can real-time monitor the valve opening degree, the liquid flow rate in the pipeline, or the liquid pressure in the pipeline, and feedback the monitored signal to the controller 105. The controller 105 can compare the feedback signal with the set value and calculate a suitable control signal, and send it to the electrically controlled valve again, thereby achieving precise closed-loop control. For example, when the feedback signal shows that the actual valve opening degree is less than the set value, the controller 105 will increase the intensity of the output signal to further open the valve, so as to always keep the actual valve opening degree consistent with the set value.

[0047] The second pipeline 103 includes a liquid container interface for detachably connecting to the liquid container 101.

[0048] For example, in the spraying device 10, the liquid container interface of the second pipeline 103 is a key component for connecting the liquid container 101 and the second pipeline 103, enabling a detachable connection between the liquid container 101 and the second pipeline 103. As a result, the operator can conveniently replace different liquid containers 101 to meet different spraying requirements. Specifically, the liquid container interface can use sealing elements such as sealing rings and gaskets to ensure the sealing performance at the connection, preventing the liquid to be sprayed from leaking or overflowing at the connection. For example, the connection between the liquid container interface and the liquid container 101 can be designed as a threaded connection, and a sealing ring can be installed at the thread. By tightening the thread, the sealing ring is compressed and deformed to achieve sealing. The connection between the liquid container interface and the liquid container 101 can also use mechanical locking devices such as buckles and snap rings to ensure the firmness of the connection. At the same time, the liquid container interface has good compatibility, enabling it to match various types of liquid containers 101.

[0049] The spraying device 10 further includes a housing 106, and the first pipeline 102, the second pipeline 103, and the controller 105 are all located inside the housing 106.

[0050] For example, as Figure 1 and Figure 2 shown, the housing 106 is an external protection structure of the spraying device 10, providing physical protection for the various components inside the spraying device 10. The housing 106 can effectively prevent external contaminants such as dust and moisture from entering the inside of the spraying device 10, protecting components such as the first pipeline 102, the second pipeline 103, and the controller 105 from pollution and corrosion. The housing 106 can also withstand a certain degree of external impact to protect the internal components from damage. For the spraying device 10 used outdoors, the material of the housing 106 usually has an anti-ultraviolet function to prevent the internal components from aging or being damaged due to long-term exposure to sunlight. By integrating components such as the first pipeline 102, the second pipeline 103, and the controller 105 inside the housing 106, the overall structure of the spraying device 10 can be made more compact, reducing the floor area and volume of the spraying device 10. It also provides a stable support structure for the internal components of the spraying device 10, ensuring that the positions and connection relationships of the various components can remain stable during the operation of the spraying device 10.

[0051] It should be noted that the liquid container 101 can be placed inside or outside the housing 106 according to actual needs and application scenarios. When the liquid container 101 is integrated with other components of the spraying device 10 (such as the first pipeline 102, the second pipeline 103, and the controller 105, etc.) inside the housing 106 to form a compact whole, the overall volume of the spraying device 10 is smaller, which is convenient for handling, storage, and overall maintenance. At the same time, it also reduces the damage of the external environment to the liquid container 101. When the liquid container 101 is located outside the housing 106 as an independent component, the capacity of the liquid container 101 can be selected according to actual needs. At the same time, the liquid container 101 can also be easily detached from the spraying device 10, which is convenient for replacement, cleaning, and maintenance, improving the versatility and flexibility of the spraying device 10.

[0052] The spraying device 10 further includes a position detection sensor 107, and the position detection sensor 107 is used to detect whether the liquid container 101 is installed in place.

[0053] For example, as Figure 2 shown, the position detection sensor 107 (such as a micro switch, a limit switch, a Hall sensor, or an optical sensor, etc.) can be used to detect whether the liquid container 101 is installed in place. If the detection result indicates that the liquid container 101 is not installed in place, the position detection sensor 107 will send a signal to the controller 105 to remind the user to check and adjust. Specifically, it can be detected whether the liquid container 101 is installed in place through mechanical contact. For example, when the liquid container 101 is installed in place, it will trigger the closure or disconnection of a micro switch or a limit switch, etc., so as to send a signal to the controller 105 to detect whether the liquid container 101 is installed in place. It can also use the occlusion or reflection of a light beam to detect whether the liquid container 101 is installed in place.

[0054] It should be noted that after the position detection sensor 107 detects that the liquid container 101 is installed in place, the spraying device 10 will start to operate. If the position detection sensor 107 detects that the liquid container 101 is not installed in place, the position detection sensor 107 will send a signal to the controller 105 and issue an alarm or prompt message through the controller 105 to remind the user to check the installation status of the liquid container 101.

[0055] The spraying device 10 further includes a storage module for storing map data, spraying area information input by the user, or preset spraying rules. The controller 105 can adjust the liquid flow rate or liquid pressure in the first pipeline 102 based on the map data, the spraying area information input by the user, or the preset spraying rules, so as to change the water spray range of the spraying device 10; and, the nozzle 104 can rotate in the horizontal direction or the vertical direction.

[0056] For example, the storage module is used to store key information related to the spraying operation, such as map data, spraying area information input by the user, or preset spraying rules, etc. Specifically, the storage module can be used to store map data, which is the basis for the spraying device 10 to achieve precise positioning and path planning. It usually includes geographical coordinates, boundary information, terrain features, etc. of the area to be sprayed. By storing the map data, the spraying device 10 can adjust the spraying parameters in a timely manner according to the geographical location during the spraying process, avoiding spraying non-target areas. The storage module can also be used to store the spraying area information input by the user, such as the shape, size of the area to be sprayed, and spraying requirements for specific areas. For example, the user can specify that certain areas need to be sprayed more intensively, while certain areas need to reduce the spraying amount. The storage module can also be used to store preset spraying rules. The preset spraying rules are spraying strategies preset according to common spraying scenarios and spraying requirements, and can include rules such as spraying amounts, spraying frequencies, or spraying times for different areas. For example, for lawn spraying, it can be preset to spray once in the early morning and once in the evening every day, and the spraying amount each time is automatically adjusted according to the area of the lawn and the soil humidity.

[0057] The controller 105 can precisely control the spraying process according to the map data, the spraying area information input by the user, or the preset spraying rules, etc. Specifically, the controller 105 can dynamically adjust the liquid flow rate or liquid pressure in the first pipeline 102 according to the map data, the spraying area information input by the user, or the preset spraying rules, so as to change the water spray range of the spraying device 10. For example, when the spraying device 10 approaches the boundary of the area to be sprayed, the controller 105 can automatically reduce the liquid flow rate or liquid pressure to reduce the spraying amount, thereby reducing the water spray range of the spraying device 10; when the spraying device 10 enters the area that needs to be sprayed more intensively, the controller 105 can increase the liquid flow rate or liquid pressure to increase the spraying amount, thereby increasing the water spray range of the spraying device 10.

[0058] It should be noted that as Figure 1 、 Figure 2 and Figure 3As shown, the nozzle 104 can rotate horizontally or vertically. The horizontal rotation of the nozzle 104 is mainly used to change the local spraying area. By horizontal rotation, the nozzle 104 can cover a wider area to ensure the uniformity of spraying. The vertical rotation of the nozzle 104 is mainly used to adjust the spraying range and the spraying water volume in different areas. By changing the pitch angle of the nozzle 104, the spraying angle of the water flow can be changed, thereby adjusting the spraying range of the water flow.

[0059] The spraying device 10 further includes a water pressure detection module located in the first pipeline 102. When the water pressure detection module detects that the liquid pressure in the first pipeline 102 does not match the liquid pressure in the second pipeline 103, it can trigger the controller 105 to adjust the liquid pressure in the second pipeline 103 so that the liquid pressure in the first pipeline 102 matches the liquid pressure in the second pipeline 103.

[0060] For example, the water pressure detection module is located in the first pipeline 102 (for example, on the inner wall of the upstream or downstream of the first pipeline 102) and is used to monitor the water pressure or liquid pressure in the first pipeline 102 in real time and compare it with the liquid pressure in the second pipeline 103. When it is detected that the liquid pressures of the two do not match, the water pressure detection module will trigger the controller 105 to adjust the liquid pressure in the second pipeline 103 to ensure that the liquid to be sprayed in the second pipeline 103 and the water flow in the first pipeline 102 can achieve a good mixing ratio and spraying effect when mixed. Specifically, the water pressure detection module can convert the detected pressure value of the liquid into an electrical signal through a pressure sensor and transmit it to the controller 105. The controller 105 can compare the liquid pressures in the first pipeline 102 and the second pipeline 103 through the electrical signal. If it is detected that the liquid pressure difference between the two exceeds a preset threshold (for example, ±0.1 MPa), the controller 105 will determine that the liquid pressure in the first pipeline 102 does not match the liquid pressure in the second pipeline 103. When the controller 105 determines that the liquid pressures of the two do not match, it will trigger corresponding control instructions to adjust the liquid pressure in the second pipeline 103. For example, the controller 105 can change the liquid pressure in the second pipeline 103 to match the liquid pressure in the first pipeline 102 by adjusting the opening of the second valve in the second pipeline 103 or adjusting the rotation speed of the power pump 1031.

[0061] In this application, whether the liquid pressure in the first pipeline 102 matches the liquid pressure in the second pipeline 103 is not limited to the equality or proximity of the two pressures. According to different application scenarios, spraying requirements, etc., the meaning of the term "match" is different. For example, to achieve certain spraying requirements, the matching of the liquid pressure in the first pipeline 102 and the liquid pressure in the second pipeline 103 can mean that the pressure values of the two differ greatly.

[0062] The spraying device 10 further includes a water flow rate detection module. The water flow rate detection module can be located in the first pipeline 102. When the water flow rate detection module detects that the liquid flow rate in the first pipeline 102 does not match the liquid flow rate in the second pipeline 103, it can trigger the controller 105 to adjust the liquid flow rate in the second pipeline 103 so that the liquid flow rate in the first pipeline 102 matches the liquid flow rate in the second pipeline 103.

[0063] For example, the water flow rate detection module is located in the first pipeline 102 (such as the inner wall of the upstream or downstream of the first pipeline 102), and is used to monitor the liquid flow rate in the first pipeline 102 in real time and compare it with the liquid flow rate in the second pipeline 103. When it is detected that the liquid flow rates of the two do not match, the water flow rate detection module will trigger the controller 105 to adjust the liquid flow rate in the second pipeline 103 to ensure that the liquid to be sprayed in the second pipeline 103 and the liquid in the first pipeline 102 (such as the external water flow) can achieve a better mixing ratio and spraying effect when mixed. Specifically, the water flow rate detection module can convert the detected liquid flow rate value into an electrical signal through a flow rate sensor (such as an electromagnetic flowmeter, a vortex street flowmeter, or an ultrasonic flowmeter, etc.) and transmit it to the controller 105. When the controller 105 determines that the liquid flow rates of the two do not match, it will trigger corresponding control instructions to adjust the liquid flow rate in the second pipeline 103. For example, the controller 105 can change the liquid flow rate in the second pipeline 103 to match the liquid flow rate in the first pipeline 102 by adjusting the opening of the second valve in the second pipeline 103 or adjusting the rotation speed of the power pump 1031.

[0064] The controller 105 can control the spraying device 10 to switch the spraying mode based on a user instruction or a preset program. The spraying mode includes a liquid medicine or fertilizer application mode and a normal spraying mode. In the normal spraying mode, the controller 105 controls the second pipeline 103 to turn off the suction function. In the liquid medicine or fertilizer application mode, the controller 105 controls the second pipeline 103 to suck the liquid in the liquid container 101.

[0065] For example, the controller 105 of the spraying device 10 can flexibly switch the spraying mode (e.g., normal spraying mode, liquid medicine or fertilizer application mode, etc.) according to user instructions or preset programs to meet different spraying requirements. Specifically, in the normal spraying mode, the spraying device 10 mainly uses the external water source in the first pipeline 102 to spray the area to be sprayed, without involving liquid medicine or fertilizer, etc., which is suitable for daily spraying requirements. In the liquid medicine or fertilizer application mode, the spraying device 10 sucks the liquid medicine or fertilizer, i.e., the liquid to be sprayed, from the liquid container 101 through the second pipeline 103, mixes it with the external water source in the first pipeline 102, and then sprays it. This mode is suitable for scenarios where pest control or nutrient supplementation of plants is required. In the normal spraying mode, the controller 105 will turn off the suction function of the second pipeline 103. In other words, the second pipeline 103 will not suck the liquid medicine or fertilizer from the liquid container 101, and the spraying device 10 only sprays using the external water source in the first pipeline 102.

[0066] It should be noted that the user can select the required spraying mode through the operation interface of the spraying device 10 (e.g., buttons, touch screens, etc.) or a remote terminal (e.g., mobile application, computer software, etc.). The controller 105 can also automatically switch the spraying mode according to the preset spraying program (e.g., spraying schedule, spraying area, spraying mode, etc. information). For example, by running the preset program, the spraying device 10 can be controlled to perform normal spraying from 6:00 to 8:00 every morning, and liquid medicine spraying on Wednesdays and Fridays every week.

[0067] The spraying device 10 provided in this application can accurately adjust the liquid flow rate or liquid pressure in the first pipeline 102 according to different spraying requirements through the controller 105, and then control the liquid flow rate or liquid pressure in the second pipeline 103, so as to achieve the precise mixing of the liquid to be sprayed in the liquid container 101 and the external water source, enabling the spraying device 10 to better adapt to areas to be sprayed with different sizes and shapes, and improving the intelligence of the spraying device 10.
