[0035] The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings.
[0036] Referring to Figure 1 With Figure 2 As shown in the figure, the present application provides a rain device 100, the rain device 100 includes a base 110, a positive pole 120 and a negative pole 130, the rain device 100 is used to sense whether there is precipitation. As in the present embodiment, the rain device 100 is configured on a walking device, such as the rain device 100 is configured on an intelligent mower 200, the rain device 100 is used to sense whether the intelligent mower 200 is in a rain environment (such as rainy day, snowy day) to control the intelligent mower 200 to automatically avoid rain. For example, the rain device 100 can be used for environmental detection or weather forecasting, etc. The specific use scene of the rain device 100 is not limited in the present application.
[0037] The base 110 comprises a body 111 and a baffle 112 surrounding the outside of the body 111. The baffle 112 is in the form of a ring structure and surrounds the body 111 in the circumferential direction. The baffle 112 protrudes from the body 111 and forms a water storage groove 113 with the body 111. The water storage groove 113 is used to collect precipitation in a rain environment. The baffle 112 is provided with at least one drainage groove 114. Preferably, the baffle 112 is integrally formed with the drainage groove 114 by injection molding or extrusion, so as to simplify the forming process of the baffle 112. The drainage groove 114 is connected to the water storage groove 113. For example, the drainage groove 114 is a through groove penetrating the thickness direction of the baffle 112. One end of the drainage groove 114 is connected to the water storage groove 113, and the other end of the drainage groove 114 is connected to the external environment. The drainage groove 114 is used to drain the rainwater accumulated in the water storage groove 113.
[0038] The positive pole 120 and the negative pole 130 are arranged on the base 110 and at least partially extend into the water storage groove 113. That is, at least part of the positive pole 120 extends into the water storage groove 113, and at least part of the negative pole 130 extends into the water storage groove 113. For example, when the rain device 100 is in a rain environment and the water storage groove 113 accumulates rainwater, the rainwater accumulated in the water storage groove 113 forms a water film that connects the positive pole 120 and the negative pole 130, so as to connect the rain device 100 and execute corresponding actions.
[0039] The rain device 100 described above can timely drain the rainwater accumulated in the water storage groove 113 to disconnect the positive pole 120 and the negative pole 130 after the rain environment changes, such as when the rain device 100 changes from a rain environment to a non-rain environment (such as a sunny day or a cloudy day), so as to switch the working mode of the rain device 100 and improve the sensing sensitivity of the rain device 100 to the environment.
[0040] In an embodiment, as shown in Figure 1 The drainage grooves 114 are multiple and are arranged at intervals along the circumferential direction of the baffle 112. In this way, the drainage efficiency of the water accumulated in the water storage groove 113 can be improved by the multiple drainage grooves 114, and the drainage grooves 114 are arranged at intervals, so as to reduce the adverse phenomenon of the water storage groove 113 having a drainage dead angle and ensure the drainage efficiency and smoothness of the water accumulated in the water storage groove 113.
[0041] For example, in the present embodiment, the drainage grooves 114 are two and are symmetrically arranged on opposite sides of the baffle 112. Of course, in other feasible embodiments, the drainage grooves 114 can also be other numbers. The specific number of the drainage grooves 114 is not limited in the present application.
[0042] Specifically, as shown in Figure 1As shown, the drainage trough 114 has a water guiding surface 115. The water guiding surface 115 is inclined relative to the water-filling surface of the water storage tank 113, such that the water guiding surface 115 is inclined as follows: Figure 1 As shown, the water guide surface 115 is inclined downwards to guide the water in the water storage tank 113 to the outside. After the rain environment changes, the water in the drainage tank 114 is discharged to the outside along the inclined water guide surface 115. The drainage tank 114 can discharge the water in the water storage tank 113 in time, improve the drainage effect of the water in the water storage tank 113, further improve the sensitivity of the rain shower device 100 to the environment, and switch the working mode of the rain shower device 100.
[0043] Further, see Figure 1 , Figure 3 and Figure 4 As shown, the angle between the water guiding surface 115 and the water-filling surface of the water storage tank 113 is 30° to 60°. If the included angle between the water guiding surface 115 and the water-filling surface of the water storage tank 113 is α, then 30° ≤ α ≤ 60°. If the included angle α between the water guiding surface 115 and the water-filling surface of the water storage tank 113 is too small, the water guiding surface 115 will not be effective in draining the water accumulated in the water storage tank 113. If the included angle α between the water guiding surface 115 and the water-filling surface of the water storage tank 113 is too large, the water guiding surface 115 will drain the water accumulated in the water storage tank 113 too quickly, which is not conducive to the accumulation of rainwater in the water storage tank 113 and the formation of a water film that connects the positive electrode post 120 and the negative electrode post 130. Specifically, the included angle α between the water guiding surface 115 and the filling level of the water storage tank 113 can be one of 30°, 35°, 40°, 45°, 50°, 55°, and 60°. Of course, the included angle α between the water guiding surface 115 and the filling level of the water storage tank 113 is not limited to the specific values provided above. The included angle α between the water guiding surface 115 and the filling level of the water storage tank 113 can also be other values within the range of 30° to 60°. This application does not limit the specific value of the included angle α between the water guiding surface 115 and the filling level of the water storage tank 113.
[0044] The aforementioned rain shower device 100, by limiting the included angle α between the water guiding surface 115 and the water-filling surface of the water storage tank 113 to 30° to 60°, can improve the drainage effect of the drainage trough 114 on the water accumulated in the water storage tank 113, thereby improving the sensitivity of the rain shower device 100 to the environment. It can also ensure that in a rain shower environment, rainwater can accumulate in the water storage tank 113 and form a water film that connects the positive electrode post 120 and the negative electrode post 130, thereby activating the rain shower device 100 and performing corresponding actions.
[0045] In one embodiment, see Figure 1As shown, the main body 111 array has multiple protrusions 116, which are spaced apart within the water storage tank 113. Preferably, the main body 111 is integrally formed with multiple protrusions 116 by injection molding, extrusion, or other methods to simplify the molding process of setting the protrusions 116 on the main body 111. Adjacent protrusions 116 are interconnected, and multiple protrusions 116 surround the outside of the positive electrode post 120 and the negative electrode post 130. The gaps between adjacent protrusions 116 store precipitation in a rainy environment, forming a water film that connects the positive electrode post 120 and the negative electrode post 130. Thus, when the rain shower device 100 is in a rainy environment, rainwater falls onto the protrusions 116 and the protrusions 116 disrupt the surface tension of the raindrops, causing the rainwater to spread rapidly and form a water film that connects the positive electrode post 120 and the negative electrode post 130, thereby quickly triggering the rain shower device 100.
[0046] Specifically, see Figure 1 As shown, the outer contour of the protrusion 116 is one of the following: cylindrical, prismatic, or conical. Thus, the tip of the protrusion 116 can effectively disrupt the surface tension of raindrops. Of course, in other feasible embodiments, the outer contour of the protrusion 116 can also be other shapes, as long as the protrusion 116 has a tip. This application does not limit the specific shape of the outer contour of the protrusion 116. Furthermore, since the protrusion 116 is located within the water storage tank 113, the protrusion 116 can be a waterproof component such as stainless steel or galvanized steel, preventing corrosion and other adverse effects from prolonged immersion in water, ensuring the working stability of the protrusion 116 in rainy environments, and improving the service life of the rain shower device 100.
[0047] In one embodiment, see Figure 1 and Figure 4 As shown, the portions of the positive terminal 120 and the negative terminal 130 that extend into the water storage tank 113 are waterproof components. That is, the portions of the positive terminal 120 and the negative terminal 130 that extend into the water storage tank 113 are waterproof components. These portions can be made of stainless steel, galvanized steel, or other waterproof materials to prevent corrosion and other adverse effects from prolonged immersion in water. This ensures the stability of the positive terminal 120 and the negative terminal 130 in rainy conditions, allowing them to maintain good electrical conductivity even after prolonged use, further extending the service life of the rain device 100.
[0048] In one embodiment, see Figure 1As shown, the rain shower device 100 further comprises a support 140. The base 110 is detachably connected to the support 140, for example, the base 110 is detachably connected to the support 140 by screwing, welding or the like. Among them, the rain shower device 100 is configured to be connected to other equipment through the support 140. For example, the support 140 is provided with a mounting hole 141, and a connecting member such as a screw, a buckle or the like is arranged in the mounting hole 141 to realize the configuration connection of the rain shower device 100 and other equipment. For example, the rain shower device 100 is configured on a walking device through the support 140, and the rain shower device 100 can control the walking device.
[0049] The rain shower device 100 described above, the base 110 is detachably connected to the support 140, only need to disassemble the base 110 and the support 140, can configure the rain shower device 100 on another device, improve the adaptability of the rain shower device 100, expand the application environment of the rain shower device 100, and reduce the use cost of the rain shower device 100.
[0050] In an embodiment, referring to Figure 1 and Figure 4 As shown, the positive pole 120 and the negative pole 130 each comprise a conductive part 150 and a conduction member 160. The conductive part 150 is embedded in the base 110, and the conductive part 150 extends into the water storage tank 113, so that when the water storage tank 113 contains rainwater, the conductive part 150 can be turned on by the water film. The conduction member 160 is electrically connected to the conductive part 150, and the conduction member 160 is used to lead out the signal of the conductive part 150. For example, the conduction member 160 is a wire, and the conduction member 160 is electrically connected to the conductive part 150, so that after the conductive part 150 of the positive pole 120 and the conductive part 150 of the negative pole 130 are turned on by the water film in the water storage tank 113, the conduction member 160 can lead out the conduction signal of the conductive part 150 and control other equipment to perform corresponding actions.
[0051] In addition, referring to Figure 1 and Figure 2 As shown, the present application provides a smart mower 200, which comprises a main body 210 and a rain shower device 100 as described above. The main body 210 is provided with a walking mechanism 220 and a control mechanism (not shown in the figure), and the control mechanism is used to control the walking mechanism 220 to work. The rain shower device 100 is arranged on the main body 210, and the rain shower device 100 is in communication connection with the control mechanism.
[0052] The intelligent mower 200 described above, when the intelligent mower 200 is in a rain environment, rainwater accumulates in the water storage groove 113 and forms a water film that connects the positive electrode column and the negative electrode column 130, the rain device 100 is connected and feeds back a rain signal to the control mechanism, and the control mechanism controls the walking mechanism 220 to perform an automatic rain-avoiding operation. For example, when the rain environment of the intelligent mower 200 changes, the drainage groove 114 timely drains the accumulated rainwater in the water storage groove 113 to disconnect the positive electrode column 120 and the negative electrode column 130, the control mechanism controls the intelligent mower 200 to switch the working mode, and the intelligent mower 200 does not need to continue to perform the rain-avoiding operation. In this way, the intelligent mower 200 timely drains the accumulated rainwater in the water storage groove 113 through the drainage groove 114 to improve the sensing sensitivity of the intelligent mower 200 to the environment, and then quickly realize the working mode switching of the intelligent mower 200.
[0053] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
