DETAILED DESCRIPTION

[0076] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0079] Integrated water and fertilizer technology, also known as fertigation, is a modern, advanced agricultural technique that combines drip irrigation and fertilization. This technology primarily utilizes drip irrigation systems, using the water in these systems as a carrier to simultaneously fertilize and irrigate, achieving integrated water and fertilizer utilization and management. This allows water and fertilizer to be optimally combined in the soil for crop absorption and utilization. However, existing fertilization systems suffer from complex designs and high costs, which also lead to difficult installation and maintenance challenges for users.

[0080] In order to overcome the above technical problems, refer to Figure 1The embodiment provides a fertilization system, which comprises an intelligent pump 100 and a liquid level sensor 300, the intelligent pump 100 comprises a pump body 11, a motor 12 and a controller 121, the motor 12 is electrically connected with the controller 121, the motor 12 is in transmission connection with the pump body 11, and the pump body 11 is connected with a fertilizer outlet 21 of a fertilizer storage container 200; the liquid level sensor 300 is installed on the fertilizer storage container 200 to monitor the liquid level height in the fertilizer storage container 200 and is in signal connection with the controller 121.

[0081] The fertilizer storage container 200 is used for storing fertilizers, the fertilization system of the embodiment pumps out the fertilizers through the intelligent pump 100, therefore, the fertilizers stored in the fertilizer storage container 200 should be in a liquid state, in application, liquid or solid fertilizers can be added into the fertilizer storage container 200, and then water is added to dissolve the fertilizers, so that the fertilizers are fully dissolved in the water to form liquid fertilizers.

[0082] The pump body 11 of the intelligent pump 100 has a liquid inlet interface 1121 and a liquid outlet interface 1122, in field installation, after the fertilizer storage container 200 and the intelligent pump 100 are fixed in positions respectively, a pipeline is used to connect the fertilizer outlet 21 of the fertilizer storage container 200 and the liquid inlet interface 1121 of the intelligent pump 100, and another pipeline is used to connect the liquid outlet interface 1122 and a drip irrigation pipeline on the site, so that the intelligent pump 100 can automatically pump out the liquid fertilizers in the fertilizer storage container 200. Preferably, the fertilizer outlet 21 is arranged at the bottom of the fertilizer storage container 200, so as to facilitate emptying of the liquid fertilizers in the fertilizer storage container 200.

[0083] Since the intelligent pump 100 itself integrates the motor 12, the controller 121 and other devices, the automatic control program can be preloaded in the controller 121, so that the intelligent pump 100 can automatically operate according to the set fertilization time and fertilization amount, the whole fertilization process does not need manual intervention, and the labor input is greatly reduced. Moreover, in field installation, the whole intelligent pump 100 can be integrally installed in position, so that the installation operation is greatly facilitated.

[0084] The liquid level sensor 300 is used for monitoring the liquid level height in the fertilizer storage container 200 and is in signal connection with the controller 121, in work, the liquid level sensor 300 can report the liquid level height in the fertilizer storage container 200 to the controller 121 in the form of an electric signal in real time, when the liquid level is too low, the controller 121 controls the motor 12 to stop rotating, so as to avoid the problem of dry running of the intelligent pump 100 and to protect the intelligent pump 100. In addition, a wireless communication module or an alarm can be arranged for the controller 121, when it is judged that the liquid level in the fertilizer storage container 200 is too low, the information can be reported to a user terminal through the wireless communication module to remind the user to add fertilizers, or the user can be prompted to add fertilizers through the alarm.

[0085] In summary, based on the fertilization system of the embodiment, automatic fertilization can be realized, including the fertilizer storage container 200, the intelligent pump 100, the liquid level sensor 300 and other structures. The controller 121 is integrated in the intelligent pump 100, and the liquid level sensor 300 is signal connected with the controller 121. During operation, the intelligent pump 100 can automatically operate according to the preset working procedure, so as to realize automatic control of the fertilization progress. Moreover, the operation of the intelligent pump 100 can be controlled in combination with the signal feedback of the liquid level sensor 300, and the advantages of high automation degree and high integration degree are achieved. Obviously, the fertilization system has the advantages of simple structure and low cost. During field application, the user only needs to simply connect the fertilizer storage container 200 and the intelligent pump 100 through a pipeline, and connect the intelligent pump 100 with a fertilization pipeline, so that the installation is simple and easy to maintain.

[0086] In an embodiment, the controller 121 is provided with a wireless communication unit, and the controller 121 communicates wirelessly with a user terminal through the wireless communication unit.

[0087] The wireless communication unit is a bridge for communication between the controller 121 and the user terminal. It can transmit the data collected by the controller 121 (such as liquid level, fertilization progress, etc.) to the user terminal in real time, so that the user can remotely monitor the running state of the fertilization system. At the same time, the user can also send instructions to the controller 121 through the user terminal, such as adjusting the fertilization time and the fertilization amount, to realize remote control.

[0088] The user terminal can be a smart phone, a tablet computer, a computer or other devices with wireless communication function. Through the user terminal, the user can check the running data of the fertilization system at any time and anywhere, and understand the fertilization progress and the liquid level. In addition, the user can also remotely control the fertilization system through the user terminal according to actual needs, such as increasing or reducing the fertilization amount, adjusting the fertilization time, etc.

[0089] In an embodiment, an external antenna 600 is further included, and the external antenna 600 is signal connected with the wireless communication unit through a first signal line 61.

[0090] Compared with the built-in antenna, the external antenna 600 usually has higher gain and wider coverage. It can more effectively capture and transmit wireless signals, thereby enhancing the communication stability and reliability between the fertilization system and the user terminal. The external antenna 600 can improve the transmission distance of wireless communication, so that the user can monitor and manage the fertilization system at a farther distance, which is particularly important for large farmland or scenarios that need remote monitoring. In complex environments (such as areas with strong signal interference), the external antenna 600 can better cope with signal attenuation and interference problems, and provide more stable and clear communication quality.

[0091] In summary, the introduction of the external antenna 600 provides more stable and efficient signal transmission for the wireless communication function of the fertilization system.

[0092] The installation position of the external antenna 600 needs to consider the signal coverage range and communication quality. Generally, the external antenna 600 should be installed at a higher position of the fertilization system to reduce the influence of ground obstacles on signal transmission.

[0093] In an embodiment, in combination with Figure 2 Further comprising an antenna support 400, and the external antenna 600 is installed on the antenna support 400.

[0094] The antenna support 400 can provide installation support for the external antenna 600, fix the external antenna 600 to a sufficient height, reduce the influence of ground obstacles on signal transmission, and obtain better signal transmission effect.

[0095] In specific applications, the antenna support 400 can include a vertical long rod, the bottom end of which is fixed to the ground, and the top end extends upward to provide sufficient support height for the external antenna 600; or the antenna support 400 can be directly installed on the top of the fertilizer storage container 200, and at this time, the installation height of the antenna support 400 can be greatly improved by using the structure of the fertilizer storage container 200, so that a smaller size of the antenna support 400 structure can be used.

[0096] Optionally, the external antenna 600 is fixed to the antenna support 400 by a grommet, and the grommet is a structure that can be repeatedly adjusted in tightness, which is convenient for adjusting the height and direction of the external antenna 600 during installation, so as to facilitate the user to install it to the most suitable position.

[0097] In an embodiment, the antenna support 400 is installed on one side of the fertilizer storage container 200, one side of the antenna support 400 extends a side support rod 41, and the liquid level sensor 300 is installed on the side support rod 41.

[0098] Specifically, the liquid level sensor 300 is installed according to the type selected, for example, when the radar liquid level meter is selected, it needs to be installed on the top of the fertilizer storage container 200; when the air pressure liquid level meter is selected, the main body needs to be installed on the top of the fertilizer storage container 200, and the air pipe is connected to the main body at one end and extends to the bottom of the fertilizer storage container 200 at the other end; when the float type liquid level meter is used, it also needs to extend from the bottom to the top of the fertilizer storage container 200 in the fertilizer storage container 200. Therefore, no matter what kind of liquid level sensor 300 is used, its top needs to be fixed reasonably. The present scheme combines the structure of the antenna support 400, which extends a side support rod 41 on one side, and the side support rod 41 is located on the top of the fertilizer storage container 200, which can provide support and fixation for the liquid level sensor 300.

[0099] In summary, the antenna support 400 of the embodiment not only bears the function of the external antenna 600, but also ingeniously combines with the installation of the liquid level sensor 300, realizes the maximization of function diversification and space utilization, that is, meets the fixed demand and saves the structural cost.

[0100] Preferably, the liquid level sensor 300 is signal-connected with the controller 121 through a third signal line 32. The third signal line 32 is bound and fixed to the antenna support 400.

[0101] Preferably, the liquid level sensor 300 is a radar liquid level meter.

[0102] The radar liquid level meter measures the liquid level by emitting microwave pulses and receiving their echoes. The radar liquid level meter does not need to be in direct contact with the measured medium, thus avoiding damage to the sensor caused by the characteristics of the medium (such as viscosity, corrosiveness, temperature, etc.), which is particularly important for the corrosive fertilizer or high-temperature environment that may exist in the fertilizer storage container 200.

[0103] In application, a detection port is arranged at the top of the fertilizer storage container 200. Under the support of the antenna support 400, the liquid level sensor 300 can be aligned with the detection port above the fertilizer storage container 200, and it emits microwave pulses into the fertilizer storage container 200 through the detection port to realize the function of detecting the liquid level. In this structure, the liquid level sensor 300 is only supported by the antenna support 400, and it is completely not in contact with the fertilizer storage container 200, so it can avoid the problem that the vibration of the fertilizer storage container 200 drives the liquid level sensor 300 to vibrate and affects the accuracy of detection. For example, a stirring mechanism 500 can be arranged for the fertilizer storage container 200 to accelerate the volume of the fertilizer and improve the uniformity of water and fertilizer, and the stirring mechanism 500 will cause the fertilizer storage container 200 to vibrate when it works.

[0104] In an embodiment, the side support rod 41 is connected with a leveling support 42, and the liquid level sensor 300 is installed on the leveling support 42 to maintain the stability of the liquid level sensor 300 through the leveling support 42.

[0105] The introduction of the leveling support 42 further enhances the stability and detection accuracy of the liquid level sensor 300 (especially the radar liquid level meter). As a high-precision measuring tool, the stability of the radar liquid level meter during operation is crucial to ensure the accuracy of the measurement results. By connecting the leveling support 42, the stable state of the radar liquid level meter during operation can be effectively maintained, thereby ensuring its detection accuracy.

[0106] Specifically, the leveling support 42 has the function of self-adaptive universal adjustment, and can be self-adaptively adjusted by the gravity of the liquid level sensor 300, so that the liquid level sensor 300 can always be positively oriented, and even if the antenna support 400 is tilted or vibrated, it can be compensated by the adjustment of the leveling support 42 itself.

[0107] In an embodiment, the leveling support 42 comprises a first support body 421 and a second support body 422, the first support body 421 is fixedly connected to the side support rod 41, and the second support body 422 is connected to the first support body 421 and can rotate relative to the first support body 421 around the X direction; the liquid level sensor 300 is connected to the second support body 422 and can rotate relative to the second support body 422 around the Z direction.

[0108] Specifically, referring to Figure 6 , the direction perpendicular to the ground is defined as the Y direction, and the two directions perpendicular to the Y direction are the X direction and the Z direction, and the X direction and the Z direction are perpendicular to each other.

[0109] As a fixed part of the leveling support 42, the first support body 421 is firmly connected to the side support rod 41, and its main function is to provide a stable support base to ensure the stability of the entire leveling support 42 system. The second support body 422 is connected to the first support body 421 and can rotate around the X direction, which allows the second support body 422 and the liquid level sensor 300 to adaptively yaw in the X direction; the liquid level sensor 300 is connected to the second support body 422 and can rotate around the Z direction, which allows the liquid level sensor 300 to adaptively yaw in the Z direction, so that when the antenna support 400 is tilted or vibrated, the leveling support 42 can be self-adaptively adjusted by the gravity of the liquid level sensor 300, so that the sensing side of the liquid level sensor 300 can always be positively downward, achieving its purpose of always being able to accurately detect the liquid level height in the fertilizer storage container 200.

[0110] In an embodiment, in combination with Figure 7 , the first support body 421 is provided with a first center hole 4211 and a first arc-shaped hole 4212, the hole axis of the first center hole 4211 extends along the X direction, the first arc-shaped hole 4212 is arranged around the first center hole 4211, the second support body 422 is rotatably connected to the first center hole 4211 through a first rotating pin 4213 and slidably connected to the first arc-shaped hole 4212 through a first guide pin 4214;

[0111] The second support body 422 is provided with a second center hole 4221 and a second arc-shaped hole 4222, the hole axis of the second center hole 4221 extends along the Z direction, the second arc-shaped hole 4222 is arranged around the second center hole 4221, the liquid level sensor 300 is rotationally connected to the second center hole 4221 through a second rotating pin 4223 and is slidably connected to the second arc-shaped hole 4222 through a second guide pin 4224.

[0112] When the antenna support 400 is tilted or vibrated, the leveling support 42 can adaptively adjust by the gravity of the liquid level sensor 300. Specifically, in the X direction, the second support body 422 can adjust its position by rotating around the first rotating pin 4213 and sliding along the first arc-shaped hole 4212, thereby compensating for the tilt or vibration in the X direction. In the Z direction, the liquid level sensor 300 can adjust its orientation by rotating around the second rotating pin 4223 and sliding along the second arc-shaped hole 4222, thereby compensating for the tilt or vibration in the Z direction, thereby ensuring that it always faces the inside of the fertilizer storage container 200 for measurement.

[0113] The present scheme adopts a combination of rotational connection and guide connection, ensuring the smoothness and stability of the second support body 422 during the swinging process of the liquid level sensor 300. Moreover, the design of this leveling support 42 is relatively compact, occupying less space while maintaining sufficient strength and rigidity.

[0114] In an embodiment, the liquid level sensor 300 includes a sensor body 31 and a sensor base 33, the sensor body is installed on the sensor base 33, and the sensor base 33 is rotationally connected to the second support body 422.

[0115] Specifically, the sensor base 33 includes a bottom frame and a connection arm extending upward on one side of the bottom frame, and the sensor body 31 is installed on the bottom frame and can transmit and receive electromagnetic waves downward through the center of the bottom frame; the connection arm extends upward and connects the second support body 422.

[0116] The sensor body 31 is the core part of the liquid level sensor 300, responsible for transmitting and receiving microwave signals to measure the liquid level. The sensor base 33 is a bridge connecting the sensor body 31 and the second support body 422, which not only provides stable support, but also allows the sensor body 31 to rotate for adjustment within a certain range. This design enables the liquid level sensor 300 to better adapt to different installation conditions and measurement requirements, with the advantage of more flexible application and installation.

[0117] In an embodiment, in combination with Figure 2 It also includes an EC / PH sensor 700 connected to the pump body 11 to monitor the EC / PH value of the fertilizer, and is in signal connection with the controller 121.

[0118] EC (Electrical Conductivity Sensor), i.e. electrical conductivity; PH (Potential of Hydrogen), i.e. pH value, the EC / PH sensor 700 is a device specifically designed to measure the electrical conductivity and pH value of a liquid, in agricultural fertilization systems, the EC value and PH value of the fertilizer are crucial for the growth of crops, the EC value reflects the concentration of soluble salts in the fertilizer solution, and the PH value indicates the degree of acidity or alkalinity of the solution, by monitoring these parameters, the quality and suitability of the fertilizer solution can be ensured.

[0119] The EC / PH sensor 700 is connected to the pump body 11, which means that the sensor is directly inserted into the fertilizer solution, which can measure the EC value and PH value in real time and accurately. The design simplifies the complexity of the system and improves the accuracy of the measurement. The EC / PH sensor 700 is in signal connection with the controller 121, which means that the data measured by the EC / PH sensor 700 can be transmitted to the controller 121 in real time for further processing and analysis, and the controller 121 can automatically adjust the parameters of the fertilization system, such as irrigation rate, time, etc., according to the received data, to ensure that the crops obtain the best growth conditions.

[0120] In addition, the controller 121 can also upload the obtained data to the user terminal, which is convenient for the user terminal to monitor the parameters of the fertilizer solution in real time, so as to make reasonable adjustments in a timely manner, such as the fertilizer in the fertilizer storage container 200 is prone to precipitation, stratification, etc. after a certain period of time, which causes the problem of uneven pumping of the fertilizer, when the fertilizer precipitates and stratifies, the EC value and PH value of the pumped fertilizer will also change, so when the user finds that the EC value and PH value of the fertilizer have changed, it can be judged that the fertilizer has precipitated and stratified, and the fertilizer can be stirred in time to make the fertilizer solution uniform.

[0121] In an embodiment, the pump body 11 includes a liquid inlet interface 1121 and a liquid outlet interface 1122, and the EC / PH sensor 700 is connected to the liquid inlet interface 1121 or the liquid outlet interface 1122.

[0122] The liquid inlet interface 1121 is the part of the pump body 11 used to receive liquid input, usually, the fertilizer solution or other liquids that need to be pumped will enter the pump body 11 through this interface. The liquid outlet interface 1122 is the part of the pump body 11 used to output liquid, the liquid (such as fertilizer solution) pressurized by the pump body 11 will be delivered to the target position, such as the irrigation system or the root of the crops, through this interface.

[0123] By directly connecting the EC / PH sensor 700 to the interface of the pump body 11, the connection distance between the sensor and the pump body 11 can be minimized, which not only simplifies the structure of the system, but also reduces the loss and interference in the signal transmission process. Since the sensor is closely adjacent to the pump body 11, the signal connection between them becomes more convenient, which can be achieved through wired or wireless means, depending on the design and requirements of the system. In addition, by directly connecting the EC / PH sensor 700 to the interface of the pump body 11, the convenience of field installation can be greatly improved, and the installer does not need to find additional installation positions near the pump body 11 or perform complex wiring work, thereby saving time and cost.

[0124] In an embodiment, referring to Figures 23-25 , the EC / PH sensor 700 includes a housing 710, a first detection probe 720, a second detection probe 730, and a control board 740, wherein,

[0125] The first detection probe 720 is built-in in the housing 710 and partially exposed on the surface of the housing 710, for detecting the electrical conductivity of the liquid;

[0126] The second detection probe 730 is built-in in the housing 710 and partially exposed on the surface of the housing 710, for detecting the pH value of the liquid;

[0127] The control board 740 is built-in in the housing 710 and electrically connected with the first detection probe 720 and the second detection probe 730 respectively.

[0128] By setting the first detection probe 720 and the second detection probe 730 on the EC / PH sensor 700, the electrical conductivity and the pH value of the liquid can be detected simultaneously; the housing 110 can be quickly installed on the corresponding component through the connecting part 713 on the housing 710, to realize the installation and fixation of the EC / PH sensor on the corresponding component.

[0129] In an embodiment, the first end surface of the housing 710 is provided with a first probe hole and a second probe hole respectively, part of the first detection probe 720 is protruded through the first probe hole to be exposed on the surface of the housing, and part of the second detection probe 730 is protruded through the second probe hole to be exposed on the surface of the housing.

[0130] Through the above structure, the main part of the first detection probe 720 and the main part of the second detection probe 730 can be well built-in in the housing 710 for isolation and protection, and at the same time, part of them is exposed through the corresponding first probe hole and second probe hole to contact with the external liquid for corresponding electrical conductivity and pH value detection of the external liquid.

[0131] In an embodiment, the end face of the first end of the shell 710 is provided with a protection structure 712, and the exposed part of the first detection probe 720 and the exposed part of the second detection probe 730 are both outside the end face of the first end of the shell 710 and both within the protection range of the protection structure 712.

[0132] Through the provision of the protection structure 712, the exposed part of the first detection probe 720 and the exposed part of the second detection probe 730 are protected while the first detection probe 720 and the second detection probe 730 are not affected in contacting the external liquid.

[0133] In an embodiment, the protection structure 712 includes a plurality of protection protrusions, and the plurality of protection protrusions are arranged along the end face of the first end of the shell 710 to surround and protect the exposed part of the first detection probe 720 and the exposed part of the second detection probe 730 outside the end face of the first end of the shell 710.

[0134] Through the arrangement of the plurality of protection protrusions, the external liquid can enter the protection space through the top opening formed by the plurality of protection protrusions to contact the first detection probe 720 and the second detection probe 730 in the protection space, or the external liquid can enter the protection space through the gap between the protection protrusions to contact the first detection probe 720 and the second detection probe 730 in the protection space, so that the exposed part of the first detection probe 720 and the exposed part of the second detection probe 730 are protected while the first detection probe 720 and the second detection probe 730 are not affected in contacting the external liquid.

[0135] In an embodiment, referring to Figure 4 , the liquid inlet interface 1121 or the liquid outlet interface 1122 of the pump body 11 is provided with a three-way pipe 71, the first interface of the three-way pipe 71 is connected to the liquid inlet interface 1121 or the liquid outlet interface 1122, and the second interface of the three-way pipe 71 is connected to the liquid inlet pipe or the liquid outlet pipe; the three-way pipe 71 is provided with a sensing interface 711, and the EC / PH sensor 700 is installed on the sensing interface 711 to sense the EC / PH value of the fertilizer flowing through the three-way pipe 71.

[0136] One opening of the tee pipe 71 is connected with the liquid inlet interface 1121 or the liquid outlet interface 1122 of the pump body 11 to ensure that the fertilizer solution can flow smoothly, and the other opening is used as an interface for connecting the liquid inlet pipe or the liquid outlet pipe to continue conveying the fertilizer solution. The third opening, i.e. the sensing interface 711, is used for installing the EC / PH sensor 700 to measure the EC and PH values of the fertilizer solution flowing therethrough. Since the EC / PH sensor 700 is connected with the pump body 11 through the tee pipe 71, it can be conveniently disassembled and replaced, which helps to reduce the maintenance cost and improve the maintainability of the system.

[0137] In an embodiment, the EC / PH sensor 700 is connected with a second signal line 72 which is connected with the controller 121 in a plug-in manner.

[0138] The second signal line 72 is used to transmit the EC and PH value data measured by the EC / PH sensor 700 to the controller 121 in real time in a wired connection manner, which can ensure that the data can be accurately and quickly transmitted. Through the plug-in connection, the wiring of the system can be significantly simplified, which not only reduces the complexity and cost of the system, but also improves the neatness and aesthetics of the system. The design of the plug-in connection also makes the connection between the EC / PH sensor 700 and the controller 121 easy to maintain and replace. When the EC / PH sensor 700 fails or needs to be upgraded, it only needs to be simply disconnected and replaced with a new EC / PH sensor 700.

[0139] In an embodiment, referring to Figure 1 The system further comprises a stirring mechanism 500 which extends into the fertilizer storage container 200 to stir the fertilizer.

[0140] Preferably, the stirring mechanism 500 is signal connected with the controller 121. The main function of the stirring mechanism 500 is to ensure that the fertilizer solution in the fertilizer storage container 200 is uniformly mixed to avoid precipitation, stratification and other phenomena. Through stirring, the various components in the fertilizer solution can be fully mixed. After the fertilizer in the fertilizer storage container 200 is left for a certain period of time, precipitation, stratification and other phenomena are likely to occur, which leads to the problem of uneven pumping of the fertilizer. When the fertilizer precipitates and stratifies, the EC and PH values of the pumped fertilizer will also change. Therefore, when the controller 121 detects that the problem of precipitation and stratification is likely to occur, it can send a stirring start command to the stirring mechanism 500 to automatically and timely stir the fertilizer solution uniformly.

[0141] Therefore, the stirring mechanism 500 in this embodiment is designed to be signal connected with the controller 121, which effectively solves the problem of uneven pumping of the fertilizer caused by precipitation and stratification of the fertilizer in the fertilizer storage container 200, and has the advantage of high automation degree.

[0142] Optionally, the stirring mechanism 500 comprises a stirring driver fixed to the top of the fertilizer storage container 200 and a stirrer connected to the stirring driver at the top end and extending downward into the interior of the fertilizer storage container 200. A support structure for supporting the stirring mechanism 500 is further arranged outside the fertilizer storage container 200.

[0143] In an embodiment, in combination with Figures 8-21 The pump body 11 comprises a pump shell 112 and a pushing mechanism 111 installed in the pump shell 112, the pushing mechanism 111 is used to push the flow of fertilizer; the motor 12 comprises a motor shell 124 and a motor body 122, the motor body 122 and the controller 121 are installed in the motor shell 124, the motor shell 124 is fixedly connected with the pump shell 112, the motor body 122 comprises a motor shaft 1221, one end of the motor shaft 1221 is connected with the pushing mechanism 111, and the other end is connected with a fan blade 123; the air flow in and out of the motor shell 124 is driven by the rotation of the fan blade 123, so as to promote the heat dissipation of the motor body 122 and the controller 121.

[0144] The pump shell 112 is provided with a pump cavity, the pump shell 112 is provided with at least one liquid inlet interface 1121 and at least one liquid outlet interface 1122, the pushing mechanism 111 arranged in the pump shell 112 is driven to operate by the motor 12, when the pushing mechanism 111 operates, the fluid can be sucked into the liquid inlet interface 1121 by suction and extruded to the liquid outlet interface 1122 after being pushed, and then extruded, so as to realize the function of conveying fluid. The pushing mechanism 111 can be reasonably selected according to the actual application scene, which can be but is not limited to impeller, blade, gear and the like, and the form of the pump cavity formed in the pump shell 112 also needs to be correspondingly arranged according to the specific form of the pushing mechanism 111.

[0145] The controller 121 is integrated in the motor 12, and the controller 121 is electrically connected with the motor body 122, which can control the power supply to the motor body 122, realize the functions of controlling the rotating speed and rotating direction of the motor body 122, and realize the purpose of automatically controlling the work of the intelligent pump 100.

[0146] The motor body 122 of the motor 12 comprises a motor shaft 1221, both ends of the motor shaft 1221 are connected with the pushing mechanism 111 and the fan blade 123 respectively, when the motor shaft 1221 operates, it will synchronously drive the pushing mechanism 111 and the fan blade 123 to rotate, the rotation of the pushing mechanism 111 can push the flow to operate, and the rotation of the fan blade 123 can drive the air flow.

[0147] In the traditional motor 12 structure, a large amount of heat is generated by the coil when the motor 12 operates, and a large amount of heat is also generated by the control panel. In order to avoid excessive heat accumulation and cause the temperature to be too high, the traditional motor 12 can only separate the motor main body 122 part and the control panel, and the two need to provide independent protection shell structures. In the structure of the motor 12 of the present scheme, the motor main body 122 and the controller 121 share a motor shell 124, which can provide installation support and protection for the motor main body 122 and the controller 121 at the same time. Compared with the form of separating the installation of the motor main body 122 and the controller 121 in the traditional scheme, the integrated installation mode of the present scheme is more compact in structure and lower in cost. It should be noted that the integration of the motor main body 122 and the controller 121 into the motor shell 124 in the present scheme is based on the reliable heat dissipation structure of the present scheme, that is, the internal and external air exchange in the motor shell 124 is driven by the operation of the fan blade 123, which realizes the rapid removal of the working heat of the motor main body 122 and the controller 121, and avoids the problem of excessive heat accumulation in the motor shell 124 leading to high temperature.

[0148] It can be understood that, in order to realize the internal and external air exchange of the motor shell 124, appropriate ventilation hole positions need to be provided on the motor shell 124 to allow the air to enter and exit.

[0149] Based on the intelligent pump 100 of the present embodiment, the motor 12 is used to drive the operation of the pushing mechanism 111 in the pump body 11 to realize the driving function. In the structure of the motor 12 of the present scheme, the motor main body 122 and the controller 121 are arranged in the motor shell 124, and the fan blade 123 is connected to the end of the motor shaft 1221 away from the pump body 11. During the operation of the motor main body 122, the fan blade 123 is also driven to rotate, which blows the air in the motor shell 124 out, and at the same time, the new air from outside is replenished into the motor shell 124, realizing the circulation of the air in and out of the motor shell 124. The heat generated by the operation of the motor main body 122 and the controller 121 is carried away by the air flow, thereby realizing effective heat dissipation of the motor main body 122 and the controller 121.

[0150] In summary, in the present embodiment, the motor main body 122 and the controller 121 are integrated into one motor shell 124, which has the advantages of compact structure, good safety, low cost, etc. At the same time, the motor 12 is used, the end of the motor shaft 1221 is connected to the fan blade 123, and the motor shaft 1221 rotates to drive the fan blade 123 to rotate to drive the internal and external air exchange, realizing the purpose of effectively promoting the heat dissipation of the motor main body 122 and the controller 121, achieving the beneficial effects of reducing the working environment temperature of the motor main body 122 and the controller 121, ensuring the stability of the work, and prolonging the service life.

[0151] In one embodiment, referring to Figure 15 The motor shell 124 is provided with a motor cavity 1243, and the motor body 122, the controller 121 and the fan blade 123 are arranged in the motor cavity 1243. The motor cavity 1243 is communicated with an air outlet 12421 on the side away from the pump shell 112. The motor shell 124 and the pump shell 112 are provided with an air inlet cavity 1244, and the air inlet cavity 1244 is communicated with a first air inlet 12411 on the side. The motor cavity 1243 and the air inlet cavity 1244 are communicated.

[0152] In this embodiment, the internal structure of the motor shell 124 is further optimized to ensure more efficient and direct heat dissipation.

[0153] Specifically, the motor shell 124 is divided into a motor cavity 1243 for accommodating the motor body 122, the controller 121 and the fan blade 123. The design of the motor cavity 1243 not only protects the internal components, but also provides a relatively closed environment for heat management. It is worth noting that the motor cavity 1243 is provided with an air outlet 12421 on the side away from the pump shell 112, which allows the heated air to be effectively cooled and smoothly discharged from the motor shell 124.

[0154] Importantly, the motor shell 124 and the pump shell 112 are ingeniously provided with an air inlet cavity 1244, which is communicated with the outside through a first air inlet 12411 on the side, providing a continuous supply of cold air to the motor cavity 1243. The motor cavity 1243 and the air inlet cavity 1244 are provided with a communication passage, which allows cold air to be blown into the motor cavity 1243 along the axial direction and directly to the motor body 122. This design ensures that the air can be directly poured into the coil of the motor body 122. Since the coil is the main part of the motor 12 that generates heat, this direct blowing method can more quickly and effectively remove the heat of the coil.

[0155] In summary, this embodiment can make the air enter the air inlet cavity 1244, blow into the motor cavity 1243 along the axial direction, and then blow axially to the motor body 122. This direction can make the air pour into the coil of the motor body 122, more quickly and directly remove the heat of the coil, and then blow out from the air outlet 12421 away from the air inlet cavity 1244, achieving the purpose of efficient and direct heat dissipation.

[0156] In addition, the air inlet cavity 1244 arranged between the motor housing 124 and the pump housing 112 can also provide sufficient space for the connection between the motor shaft 1221 and the pushing mechanism 111, thereby ensuring the reliability of the connection between the motor shaft 1221 and the pushing mechanism 111.

[0157] In an embodiment, in combination with Figure 18 The motor cavity 1243 and the air inlet cavity 1244 are separated by a motor bottom plate 12413, and the motor bottom plate 12413 is provided with a first air passage hole 12412 that communicates the motor cavity 1243 and the air inlet cavity 1244.

[0158] The first air passage hole 12412 provided on the motor bottom plate 12413 can be used for ventilation, so that the air in the air inlet cavity 1244 can smoothly enter the motor cavity 1243.

[0159] In an embodiment, the motor body 122 includes a stator assembly 1222 and a rotor assembly 1223, the rotor assembly 1223 includes a coil, the stator assembly 1222 is fixed to the motor bottom plate 12413, the rotor assembly 1223 is sleeved on the outer periphery of the stator assembly 1222 and is spaced apart from the motor bottom plate 12413, and the first air passage hole 12412 is arranged in alignment with the rotor assembly 1223.

[0160] The motor body 122 is composed of the stator assembly 1222, the rotor assembly 1223, and the motor shaft 1221, wherein the stator assembly 1222 is fixedly arranged on the motor bottom plate 12413, the rotor assembly 1223 is sleeved on the outer periphery of the stator assembly 1222, and the motor shaft 1221 is fixedly connected with the rotor assembly 1223. When electricity is supplied, the rotor assembly 1223 rotates relative to the stator assembly 1222, thereby driving the motor shaft 1221 to rotate synchronously. In this scheme, the first air passage hole 12412 is carefully arranged on the motor bottom plate 12413, and these hole positions are accurately aligned with the rotor assembly 1223. Since the coil in the rotor assembly 1223 is the main part that generates heat in the motor 12, this alignment design can ensure that the cold air entering from the air inlet cavity 1244 can directly blow to the coil, thereby more effectively removing the heat.

[0161] In specific implementation, the motor bottom plate 12413 needs to be provided with a shaft hole that allows the motor shaft 1221 to pass through, so that the motor shaft 1221 can extend into the air inlet cavity 1244 to connect with the pushing mechanism 111.

[0162] In an embodiment, in combination with Figure 17The stator assembly 1222 is connected with a reinforcing bottom plate 1224 near one side of the motor bottom plate 12413, the reinforcing bottom plate 1224 is fixed on the motor bottom plate 12413, and the reinforcing bottom plate 1224 is provided with a second air passing hole corresponding to the first air passing hole 12412.

[0163] The reinforcing bottom plate 1224 is newly added to one side of the stator assembly 1222 near the motor bottom plate 12413. This design not only enhances the structural strength of the stator assembly 1222, but also provides convenience for the assembly between the stator assembly 1222 and the motor bottom plate 12413. Specifically, the reinforcing bottom plate 1224 can provide a larger connection area, which can be specifically set to have a larger cross-sectional area than the stator assembly 1222, so that it is more convenient to firmly and reliably fix the reinforcing bottom plate 1224 to the motor bottom plate 12413, such as distributed multiple bolt fastening; the connection between the reinforcing bottom plate 1224 and the stator assembly 1222 can adopt welding connection or bolt connection, so the structure improves the structural strength of the stator assembly 1222 installation. During assembly, the stator assembly 1222 and the reinforcing bottom plate 1224 can be fixed and connected first, and then the reinforcing bottom plate 1224 is fixed to the motor bottom plate 12413 as a whole. This way not only improves the assembly efficiency, but also enhances the reliability of the connection between the stator assembly 1222 and the motor bottom plate 12413; in addition, this way also facilitates the disassembly and assembly work of the motor main body 122 during maintenance, that is, only the reinforcing bottom plate 1224 needs to be removed, and the motor main body 122 can be disassembled.

[0164] The reinforcing bottom plate 1224 of the scheme is provided with a second air passing hole corresponding to the first air passing hole 12412 on the motor bottom plate 12413. In this way, when the cold air enters the motor cavity 1243 from the air inlet cavity 1244 through the first air passing hole 12412, it can continue to pass through the second air passing hole on the reinforcing bottom plate 1224, further ensuring the effective cooling of the stator assembly 1222 and the rotor assembly 1223.

[0165] In an embodiment, the motor bottom plate 12413 is provided with a support rib network 12416 near one side of the motor cavity 1243, and the reinforcing bottom plate 1224 abuts against the support rib network 12416.

[0166] The support rib network 12416 is formed by a series of longitudinal and transverse intersecting ribs, which form a dense grid structure on the motor bottom plate 12413. When the reinforcing bottom plate 1224 is fixed to the motor bottom plate 12413, it will tightly abut against the support rib network 12416, which ensures the stable connection between the reinforcing bottom plate 1224 and the motor bottom plate 12413.

[0167] In an embodiment, in combination with Figure 11 and Figure 16 , the motor housing 124 is provided with a second air inlet 12422 corresponding to the mounting position of the controller 121.

[0168] The second air inlet 12422 provides an additional heat dissipation channel for the controller 121. Since the controller 121 also generates heat during the operation of the motor 12, the cold air introduced through the second air inlet 12422 can directly blow onto the controller 121 to help dissipate heat. In this way, the controller 121 can be kept at a relatively low operating temperature, thereby improving its operating efficiency and stability.

[0169] In an embodiment, in combination with Figure 22 , the controller 121 is provided with a plug-in seat 1211, and the second air inlet 12422 is correspondingly arranged with the plug-in seat 1211 to allow an external connector to be plugged into the plug-in seat 1211 through the second air inlet 12422.

[0170] The plug-in seat 1211 facilitates current transmission and signal transmission between the controller 121 and external devices. Specifically, through the plug-in seat 1211, the connectors of external power lines and signal lines can be plugged into the plug-in seat 1211 to achieve power supply to the controller 121 and the motor body 122, and to achieve signal transmission between the controller 121 and external devices. The controller 121 can exchange data and communicate with other electronic devices or systems, thereby realizing remote monitoring and control of the entire motor 12 system. This design not only improves the intelligence of the system, but also provides users with a more convenient and flexible operation method.

[0171] In addition, the second air inlet 12422 on the motor housing 124 is directly used as a window allowing the external connector to pass through, which meets the requirements of directly blowing air to the controller 121 and the insertion connection of the external connector, reduces the number of holes on the motor housing 124, and is beneficial to improve the reliability of the motor housing 124 and the protection capability of the motor housing 124 to the internal devices.

[0172] In an embodiment, in combination with Figure 19 and Figure 20 , the controller 121 is provided with a control protection cover 1212, and the control protection cover 1212 is provided with a plug-avoiding hole corresponding to the plug seat 1211.

[0173] The introduction of the control protection cover 1212 also improves the safety and reliability of the entire controller 121, which can prevent dust, moisture and other sundries from entering the inside of the controller 121, thereby avoiding the failure or damage of the controller 121 caused by environmental factors. The plug-avoiding hole provided on the control protection cover 1212 allows the external connector to be smoothly plugged into the plug seat 1211 when needed, without being hindered by the control protection cover 1212, which not only ensures the convenience of connection, but also ensures that the controller 121 can normally communicate and exchange data with external devices while being protected.

[0174] In specific implementation, sealing measures such as sponge pads or rubber pads are taken between the periphery of the plug seat 1211 and the control protection cover 1212 to improve the dustproof and waterproof capability. In specific setting, a sufficient gap is reserved between the control protection cover 1212 and the edge of the second air inlet 12422 to provide the required air inlet.

[0175] In an embodiment, the control protection cover 1212 is provided with a heat dissipation fin 12121.

[0176] Specifically, when the controller 121 is working, the heat generated by the controller 121 is transferred to the control protection cover 1212 through heat conduction, and the heat dissipation fin 12121 can quickly disperse the heat to a larger surface area and take away the heat through air convection.

[0177] In an embodiment, in combination with Figure 16 , Figure 17 and Figure 19 , the motor bottom plate 12413 is provided with a support frame 12415, the peripheral part of the control protection cover 1212 is sealingly connected with the support frame 12415, and the controller 121 is installed on the side of the control protection cover 1212 facing the motor bottom plate 12413.

[0178] The support frame 12415 is firmly mounted on the motor base plate 12413, forming a recess with a certain depth that can perfectly accommodate the protruding electronic components that may exist on the controller 121, thereby avoiding damage caused by component collision or extrusion during installation. The peripheral part of the control protection cover 1212 is tightly attached to the support frame 12415 through a sealing connection (such as using sealing strips, sealing rings, etc.), thereby effectively preventing dust, moisture and other debris from entering the interior of the controller 121. This sealing design not only improves the protection level of the controller 121, but also ensures its stable operation in harsh environments.

[0179] In general, the design of the support frame 12415 and the control protection cover 1212 in this embodiment collectively provides a stable, secure and sealed installation environment for the controller 121, enhancing the reliability and durability of the controller 121.

[0180] In addition, the controller 121 is installed on the control protection cover 1212, which facilitates the direct transfer of heat from the controller 121 to the control protection cover 1212 and the direct dissipation by the control protection cover 1212, i.e. this structure facilitates the optimization of the heat dissipation of the controller 121.

[0181] In an embodiment, the controller 121 is provided with a main control unit and an electric adjustment unit.

[0182] The main control unit is the core part of the controller 121, which is responsible for processing various signals from the system inside and outside the application, and making decisions and controls according to the preset algorithm and logic. The main control unit usually has high computing power and stability, which can ensure the stable operation of the motor 12 system under various working conditions.

[0183] The electric adjustment unit is the part of the controller 121 directly related to the motor 12, which is responsible for receiving instructions from the main control unit and controlling the speed, direction and power of the motor 12. The electric adjustment unit usually has precise current and voltage control capability, which can realize precise control of the motor 12, thereby improving the efficiency and performance of the motor 12 system.

[0184] By integrating the main control unit and the electric adjustment unit on the controller 121, comprehensive control and optimization of the motor 12 system can be achieved. This design not only improves the integration and reliability of the system, but also makes the controller 121 more comprehensive and powerful.

[0185] In an embodiment, in combination with Figure 10The motor housing 124 includes a motor bottom shell 1241 and a motor cover 1242. The motor bottom shell 1241 is fixedly connected with the pump shell 112. The motor cover 1242 covers the side of the motor bottom shell 1241 away from the pump shell 112. The air inlet cavity 1244 is formed between the motor bottom shell 1241 and the pump shell 112. The motor cavity 1243 is formed between the motor cover 1242 and the motor bottom shell 1241.

[0186] The motor cover 1242 covers the side of the motor bottom shell 1241 away from the pump shell 112, forming a relatively closed space, i.e., the motor cavity 1243. The motor cavity 1243 is the main working area of the motor 12, which contains the stator assembly 1222, the rotor assembly 1223, and the controller 121, etc. The design of the motor cover 1242 not only protects these components from external environment interference and damage, but also provides a relatively quiet and stable working environment for them.

[0187] Meanwhile, the air inlet cavity 1244 is formed between the motor bottom shell 1241 and the pump shell 112. The design of the air inlet cavity 1244 is to introduce cold air to help the motor 12 and the pump dissipate heat. The cold air can enter the air inlet cavity 1244 through the air inlet on the motor housing 124, then flow through the heat dissipation area of the motor 12, and finally be discharged through the air outlet 12421.

[0188] In an embodiment, the motor bottom shell 1241 includes a motor bottom plate 12413 and a bottom plate surrounding wall 12414 arranged around the periphery of the motor bottom plate 12413. The bottom plate surrounding wall 12414 extends to the side where the pump shell 112 is located and is connected to the pump shell 112. The first air inlet 12411 is arranged on the bottom plate surrounding wall 12414, and / or the air outlet 12421 is arranged on the motor cover 1242.

[0189] The motor bottom plate 12413 is the planar part of the motor bottom shell 1241, which provides a mounting platform for the motor main body 122 and the controller 121, etc. The bottom plate surrounding wall 12414 is a vertical wall arranged around the periphery of the motor bottom plate 12413. It extends to the side where the pump shell 112 is located and is tightly combined with the pump shell 112 through fixed connection (such as bolt connection, welding, etc.). This design not only enhances the connection strength between the motor bottom shell 1241 and the pump shell 112, but also forms a relatively closed space (i.e., the air inlet cavity 1244) and provides protection for the connection structure of the motor shaft 1221 and the pump body 11.

[0190] In an embodiment, an air inlet shroud 131 is further included, which is installed on the motor shell 124 corresponding to the side of the first air inlet 12411, a uniform air interval 1312 is formed between the air inlet shroud 131 and the motor shell 124, and a third air inlet 1311 is arranged on the air inlet shroud 131, which is arranged in a staggered manner with the first air inlet 12411.

[0191] Specifically, during operation, external air enters through the third air inlet 1311, passes through the uniform air interval 1312, and then enters the air inlet cavity 1244 through the first air inlet 12411. This structure can ensure the uniformity and stability of the airflow, and can also block the dust entering through the third air inlet 1311, that is, the dust entering the uniform air interval 1312 through the third air inlet 1311 will impact the motor shell 124, avoiding the dust entering the air inlet cavity 1244 through the first air inlet 12411 again.

[0192] In an embodiment, a pump base 13 is further included, and the pump body 11 and the motor 12 are integrally installed on the pump base 13.

[0193] The introduction of the pump base 13 provides additional stability and convenience for the installation of the pump body 11 and the motor 12. The pump base 13 is a specially designed structural component that is used to carry and fix the pump body 11 and the motor 12, ensuring that they can maintain stability and reliability during operation.

[0194] In an embodiment, in combination with Figure 10 and Figure 13 , the first air inlet 12411 is arranged on the bottom side of the motor shell 124, and the air inlet shroud 131 is arranged on the top side of the pump base 13.

[0195] By combining the air inlet shroud 131 into the structure of the pump base 13, the function of air inlet dust prevention can be achieved while simplifying the structure of the entire device. Importantly, by arranging the first air inlet 12411 on the bottom side of the motor shell 124 and the air inlet shroud 131 of the pump base 13 below the motor shell 124, the air inlet direction is from bottom to top, and when the air enters through the third air inlet 1311, the dust carried therein will impact the motor shell 124 upwards, and then the dust will fall downwards under the action of its own gravity, and then fall out of the third air inlet 1311 in the opposite direction, that is, this structure can achieve the effect of automatically discharging dust.
