DETAILED DESCRIPTION

[0027] The embodiments of the present disclosure will be described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0028] With the popularization of intelligent gardens, more intelligent lawn irrigation devices are needed to irrigate lawn areas with specific boundaries on demand and quantitatively in a more time-saving and labor-saving manner.

[0029] Figure 1 The intelligent irrigation device 100 of the embodiments of the present disclosure is shown, which can intelligently determine and adjust the control parameters according to the boundary data of the to-be-irrigated area or user demand, and irrigate the lawn area with specific boundaries in a more energy-saving and efficient manner according to the determined or adjusted control parameters.

[0030] As Figure 2 shown, the irrigation device 100 disclosed in some embodiments of the present specification can include a water flow channel 110, which is provided with a water inlet 111 and a water outlet 112 at both ends. The water inlet 111 can be connected to an external water source such as a water pipe. Water in the external water pipe can be guided into the water flow channel 110 through the water inlet 111 and flow out from the water outlet 112. The water outlet 112 can include a nozzle, etc. Water flow can be sprayed from the nozzle to irrigate the to-be-irrigated area where the irrigation device 100 is located. In addition, a water flow driving assembly such as a water pump can be provided in the irrigation device 100. The water from the external water source is guided into the water flow channel 110 by the water flow driving assembly, i.e. from the water inlet 111 to the water outlet 112.

[0031] As Figure 2 shown, the irrigation device 100 can also include a water flow control valve 120, which can be provided on the water flow channel 110 for adjusting the water flow parameters such as flow rate, flow speed or water pressure, etc. flowing through the water flow channel 110. As Figure 3 Figure 5 ​As shown, the water flow control valve 120 can include a valve inlet 121 and a valve outlet 122 opposite to the water flow passage 110, and the water flow parameter (e.g., flow rate or flow speed, etc.) of the water flow control valve 120 can be controlled by controlling the contact area between the valve inlet 121 and the valve outlet 122 and the water flow passage 110, so as to control the water flow parameter (e.g., flow rate or flow speed, etc.) of the water flow through the water flow passage 110 and the water outlet 112. The water flow control valve 120 can be configured at any suitable position on the water flow passage 110. In different embodiments, the water flow control valve 120 can be any suitable type of controllable valve, such as an electrically controlled valve, an electrically driven floating ball valve, a hydraulically driven control valve, an electromagnetically controlled valve, a flow control valve, etc., so that the flow rate, flow speed or water pressure of the water flow in the water flow passage 110 can be controlled by the opening degree, opening duration, closing duration, switching frequency, switching period, etc. of the valve inlet 121 and the valve outlet 122 of the water flow control valve 120.

[0032] The irrigation device 100 in the embodiments of the present specification can further include a controller (not shown in the figures), which can include any circuit and / or module having data processing capability and / or instruction execution capability and suitable for the irrigation device 100, such as a central processing unit (CPU), a graphics processing unit (GPU), a field programmable gate array (FPGA), etc., and can be configured to perform data processing and / or control related to the irrigation operation and / or other functions of the irrigation device 100 according to program instructions stored in a memory (not shown in the figures) in the irrigation device 100, etc.

[0033] For example, the controller can be directly or indirectly connected or coupled with other controllable components of the irrigation device 100, such as the water flow control valve 120, by any suitable means (including wired connection and / or wireless connection), and control the water flow parameter (e.g., flow rate or flow speed) of the water outlet 112 of the water flow passage 110 by controlling the water flow parameter (e.g., flow rate or flow speed) of the valve inlet 121 and the valve outlet 122 of the water flow control valve 120.

[0034] As shown, the water flow control valve 120 can include a valve inlet 121 and a valve outlet 122 opposite to the water flow passage 110, and the water flow parameter (e.g., flow rate or flow speed, etc.) of the water flow control valve 120 can be controlled by controlling the contact area between the valve inlet 121 and the valve outlet 122 and the water flow passage 110, so as to control the water flow parameter (e.g., flow rate or flow speed, etc.) of the water flow through the water flow passage 110 and the water outlet 112. The water flow control valve 120 can be configured at any suitable position on the water flow passage 110. In different embodiments, the water flow control valve 120 can be any suitable type of controllable valve, such as an electrically controlled valve, an electrically driven floating ball valve, a hydraulically driven control valve, an electromagnetically controlled valve, a flow control valve, etc., so that the flow rate, flow speed or water pressure of the water flow in the water flow passage 110 can be controlled by the opening degree, opening duration, closing duration, switching frequency, switching period, etc. of the valve inlet 121 and the valve outlet 122 of the water flow control valve 120. Figures 2-6As shown, the water flow control valve 120 can be configured as a rotatable valve such as a ball valve, etc. The controller can control the water flow parameters of the valve inlet 121 and the valve outlet 122 by controlling the rotation of the water flow control valve 120, and the rotation is conducive to the accurate control of the water flow parameters of the water flow control valve 120. For example, the controller can control the rotation of the water flow control valve 120 to adjust the area of the valve inlet 121 and the valve outlet 122 connected with the water flow channel 110, so as to adjust the opening degree of the water flow control valve 120, and then adjust the water flow parameters of the water flow channel 110, and finally control and adjust the water flow parameters of the water outlet 112 of the water flow channel 110. For example, the controller can adjust the rotation angle of the water flow control valve 120 according to the boundary information of the to-be-irrigated region, so that the irrigation device 100 can irrigate along the boundary of the to-be-irrigated region.

[0035] In the process of rotating the water flow control valve 120, the flow of water passing through the valve outlet 122 linearly increases (or approaches linear increase) or linearly decreases (or approaches linear decrease), that is, the flow of water passing through the valve outlet 122 changes regularly. For example, the shape of the valve outlet 122 can be set so that the area of the valve outlet 122 connected with the water flow channel 110, that is, the opening degree of the valve outlet 122, changes linearly when the water flow control valve 120 rotates, and then the flow of water passing through the valve outlet 122 and the water outlet 112 changes linearly. By controlling the flow of water of the water outlet 112, the range of the irrigation device 100 can be controlled. If the flow of water passing through the valve outlet 122 and the water outlet 112 changes linearly, the range of the irrigation device 100 can be easily adjusted to meet the needs of different users in different scenarios.

[0036] As shown in Figure 4 , Figure 5 As shown in Figure 6 , the opening direction of the "V"-shaped opening can be configured to be parallel or substantially parallel to the rotation direction of the water flow control valve 120, that is, the base of the triangle is perpendicular to the rotation direction of the water flow control valve 120. In this way, the contact area of the valve outlet 122 with the water flow channel 110 when the water flow control valve 120 rotates can be represented as the product of the base and the height of the triangle. In the process of rotating the water flow control valve 120, the contact area of the valve outlet 122 with the water flow channel 110 changes linearly with the length of the height and the length of the base of the valve outlet 122 connected with the water flow channel 110, and then the flow of water passing through the valve outlet 122 and the water outlet 112 can be linearly controlled.

[0037] As shown in Figure 5As shown, the valve inlet 121 can be configured as circular, which increases the adjustment range of the water inflow of the valve core 123. Of course, the valve inlet 121 and the valve outlet 122 can also be set to other shapes, such as rectangles, as long as they meet the principle of this scheme.

[0038] like Figures 3-4 As shown, the water flow control valve 120 may include a valve core 123 and a housing 124. The valve core 123 is rotatably disposed within the housing 124 and has a valve inlet 121 and a valve outlet 122. Both ends of the housing 124 are connected to the water flow channel 110, and the valve inlet 121 and valve outlet 122 are opposite to the two ends of the housing 124. When the valve core 123 rotates within the housing 124, the contact area between the valve inlet 121 and valve outlet 122 and the water flow channel 110 connected to the two ends of the housing 124 changes accordingly, thereby altering the water flow parameters of the water flowing through the water flow control valve 120. The housing 124 protects and seals the valve core 123, preventing water from flowing from the connection between the valve core 123 and the water flow channel 110 to the outside of the water flow channel 110.

[0039] like Figure 6 As shown, the irrigation device 100 also includes a valve drive assembly, which can be used to drive the water flow control valve 120 to rotate. The valve drive assembly may include a drive motor 131 and a gear 132. The gear 132 can be a single gear or a gear set, such as a reduction gear set, which can be configured according to actual needs. The controller is also configured to control the drive motor 131 to drive the gear 132 to rotate, and the gear 132 drives the water flow control valve 120 to rotate. The gear drive method makes it easier to adjust the rotation angle, speed, and valve opening of the water flow control valve 120.

[0040] like Figure 6 As shown, the water flow control valve 120 also includes a valve stem 125, one end of which is connected to the gear 132, and the other end is connected to the water flow control valve 120. Figure 6 As shown in one embodiment of this specification, gear 132 may include two gears meshing with each other. One gear is connected to the output shaft of drive motor 131, and the shaft of the other gear may be connected to valve stem 125. Drive motor 131 drives the gear connected to it to rotate, which in turn drives valve stem 125 connected to the gear to rotate. The rotation of valve stem 125 drives water flow control valve 120 (e.g., valve core 123) connected to it to rotate.

[0041] Furthermore, the valve stem 125 can be integrally formed with the valve core 123, or it can be non-detachably connected to the valve core 123, such as by welding. Of course, the valve stem 125 can also be detachably connected to the valve core 123, such as... Figure 4As shown, a valve rod connecting groove 126 can be arranged on the valve core 123, and one end of the valve rod 125 can be matched with the valve rod connecting groove 126 to be connected with the valve core 123 through the valve rod connecting groove 126. The valve core 123 is connected with the output gear 132 of the speed reducer through the valve rod 125 in a small gap fit, and a magnetic steel of an encoder is arranged above the output gear 132, and the controller can determine the opening and closing angle of the large gear 132 and the valve core 123 by detecting the relative angle of the magnetic steel, so as to realize the accurate control of the water flow. The control accuracy of the water flow control valve 120 in the embodiment of the present application can be controlled to be ±0.5°.

[0042] In addition, the irrigation device 100 can also be provided with a sealed shell 140, wherein the controller (such as a water flow control valve control panel), the driving motor 131, the gear 132 and the water flow control valve 120 and other components that need to be waterproof can be arranged in the sealed shell 140, and the components that need to be waterproof are separated from the waterway through the sealed shell 140, so as to ensure the stability of the overall structure of the irrigation device 100.

[0043] Of course, the irrigation device 100 can also include other components, such as a base, which can be used to set the irrigation device 100 at a suitable position of the area to be irrigated, and the water flow parameters of the water outlet 112 of the water flow channel 110 can be controlled by controlling the water flow parameters of the valve inlet 121 and the valve outlet 122 of the water flow control valve 120, so as to control the range of the irrigation device 100, so that the entire area to be irrigated can be irrigated without moving the irrigation device 100, realizing the functions of intelligent and automatic irrigation and improving the irrigation efficiency. The irrigation device 100 can also be provided with a liquid medicine bottle to spray liquid medicine on the lawn that needs to be treated by the irrigation device 100. Other components can also be arranged on the irrigation device 100 according to the needs, and the embodiments of the present application are not limited.
