[0052] See Figures 1 to 12 , the present utility model provides an operating device with a two-way drainage function, including a base 1, a top cover 2, and a key mechanism 4 provided on the top cover 2. The top cover 2 is fixed above the base 1, forming a main device chamber therebetween. The base 1 is provided with a working cavity 11 for accommodating a working execution mechanism 3. The key mechanism 4 includes a key bracket 42 and an operation key 41. The key bracket 42 is provided with a key slot cavity 421, and the operation key 41 is movably installed in the key slot cavity 421. A mechanical reset structure is also provided in the key slot cavity 421 for the upward reset of the operation key 41. A first drainage port 12 is provided on the inner wall surface of the working cavity 11, and the first drainage port 12 is preferably provided on the top surface of the working cavity 11. A second drainage port 422 is provided on the inner wall surface of the key slot cavity 421, and the second drainage port 422 is preferably provided on the top surface of the key slot cavity 421. The first drainage port 12 and the second drainage port 422 are connected, and the connection method can be direct or through an intermediate pipeline. The first drainage port 12 is preferably located below the second drainage port 422; there is a drainage gap 43 between the operation key 41 and the key slot cavity 421, and the size of the drainage gap 43 can be set according to actual conditions. The drainage gap 43 communicates the key slot cavity 421 with the outside above the top cover 2, and can drain the water in the key slot cavity 421 to the outside.
[0053] The operating device related to the present utility model, when used outdoors normally, if water enters the key slot cavity 421 through the drainage gap 43 between the operation key 41 and the key slot cavity 421, it will be automatically discharged through the second drainage port 422 on the bottom surface of the key slot cavity 421, enter the working concave cavity 11 through the second drainage port 422, and be discharged from the bottom of the working concave cavity 11, thereby preventing water accumulation in the key slot cavity 421 from affecting the key mechanism 4. When flushing the working actuator 3 at the bottom, the operating device needs to be turned upside down, and then the working actuator 3 is flushed. At least part of the water that enters the working concave cavity 11 can automatically flow into the first drainage port 12 under the action of gravity and be discharged through the drainage gap 43 between the operation key 41 and the key slot cavity 421.
[0054] The operating device of the present utility model, by setting a drainage structure composed of a drainage gap 43, a key slot cavity 421, a first drainage port 12, a second drainage port 422, and a working concave cavity 11, can achieve two-way drainage during normal use and flipping flushing of the operating device, and timely discharge the water in the key slot cavity 421 and the working concave cavity 11, reducing the influence of water accumulation on the key mechanism 4 and the working actuator 3. And by draining water through the drainage gap 43 between the operation key 41 and the key slot cavity 421, there is no need to set additional drainage holes on the top cover 2, reducing the influence on the structure of the top cover 2.
[0055] See Figure 4 、 Figure 5 and Figure 11 In this embodiment, as a preferred design, a middle connecting pipe 44 is also fixedly connected to the bottom of the key bracket 42. The upper end of the middle connecting pipe 44 is communicated with the second drainage port 422, and the lower end is connected to the first drainage port 12. By using the middle connecting pipe 44 to connect the first drainage port 12 and the second drainage port 422, the pipe can be laid according to the layout in the main chamber of the operating device, which is more flexible in use and reduces the influence on the layout in the main chamber of the device. In this embodiment, the first drainage port 12 is located below the second drainage port 422, and the middle connecting pipe 44 is set as a straight pipe, shortening the middle path and having a simpler structure. In other embodiments, the first drainage port 12 and the second drainage port 422 can also be arranged with an offset up and down, and the middle connecting pipe 44 can also be bent. To further facilitate drainage, the first drainage port 12 is preferably set at the highest position on the top surface of the working concave cavity 11, and the second drainage port 422 is preferably set at the lowest position on the bottom surface of the key slot cavity 421.
[0056] See Figure 4 、 Figure 5 and Figure 11, in this embodiment, further preferably, the first drain port 12 is provided with a connecting pipe 13 extending upward. The lower end of the intermediate communication pipe 44 is inserted into the connecting pipe 13, and the walls between the two are sealed, specifically, it can be sealed by setting a plurality of sealing rings. By adopting the above method, it is convenient for the connection and assembly of the intermediate communication pipe 44 and the first drain port 12. At the same time, there is a certain connection flexibility between the intermediate communication pipe 44 and the connecting pipe 13, and when the working equipment vibrates, the intermediate communication pipe 44 can generate a slight displacement relative to the connecting pipe 13. In other embodiments, the lower end of the intermediate communication pipe 44 can also be connected to the first drain port 12 by using a hose or other suitable connection method.
[0057] See Figure 4 , Figure 5 and Figure 11 , in this embodiment, as a preferred design, the key bracket 42 is detachably fixed to the top cover 2 by bolts, and the connection is sealed, so that the key slot cavity 421 and the intermediate communication pipe 44 are sealed and isolated from the main chamber of the device, preventing water from entering the main chamber of the device. The intermediate communication pipe 44 and the key bracket 42 are integrally formed and manufactured by an integral molding method, which is convenient for manufacturing and installation. In other embodiments, the intermediate communication pipe 44 can also be separately manufactured from the key bracket 42 and fixedly connected to the key bracket 42.
[0058] See Figure 6 , Figure 7 and Figure 11, in this embodiment, as a preferred design, the working device further includes a Hall trigger component 5 for sensing the pressing action of the operation button 41 and outputting a signal. The Hall trigger component 5 includes a magnet 52 and a sensing output part 51 for sensing the position of the magnet 52 and outputting a signal. Among them, the sensing output part 51 generally includes a magnetosensitive element, an output circuit, etc. The sensing output part 51 can sense the approach of the magnet 52 and output a corresponding electrical signal. The specific structural principle of the Hall trigger component 5 is existing and will not be elaborated here. An active accommodation cavity 423 communicating with the bottom of the button slot cavity 421 is provided in the button bracket 42. An extension rod 411 extending into the active accommodation cavity 423 is provided on the operation button 41. The active accommodation cavity 423 provides a movement space for the up and down movement of the extension rod 411. The sensing output part 51 is fixedly arranged in the main chamber of the device between the top cover 2 and the base 1, preferably directly fixed on the outer surface of the button bracket 42. The magnet 52 is fixedly arranged on the extension rod 411. After the operation button 41 is pressed down, the magnet 52 on the extension rod 411 approaches the sensing output part 51, and the sensing output part 51 outputs an electrical signal. The controller of the working device can control the working device to perform corresponding actions according to this electrical signal. Specifically, in this embodiment, the operation button 41 is an emergency STOP button. When pressed, the working device stops all work, the mowing cutter disc stops rotating, and the wheels also stop. The side of the active accommodation cavity 423 in the button bracket 42 can be connected to the inside of the intermediate connecting pipe 44, which is convenient for manufacturing. Of course, the active accommodation cavity 423 and the inside of the intermediate connecting pipe 44 can also be not connected. By using the Hall trigger component 5 to sense the operation button 41 and trigger the action of the working device, there is no need for direct contact between the sensing output part 51 and the magnet 52. Compared with mechanical or other triggering methods, better sealing isolation can be achieved between the inside of the button bracket 42 and the main chamber of the device, so as to ensure the overall sealing performance and prevent water from entering the main chamber of the device. In other embodiments, the magnet 52 can also be installed inside the button bracket 42 in other ways, fixed to the operation button 41, and capable of moving synchronously with the operation button 41.
[0059] In this embodiment, as a preferred design, both the first drain port 12 and the second drain port 422 are provided with filter meshes, and the mesh size of the filter mesh is set according to actual needs to prevent sundries from entering the water channel and causing blockage. In other embodiments, it can also be that only one of the first drain port 12 and the second drain port 422 is provided with a filter mesh, or a filter mesh can also be provided in the intermediate connecting pipe 44.
[0060] In this embodiment, refer to Figure 1 , the working device is a lawn mower, and the work execution mechanism 3 is a mowing mechanism, including a mowing cutter disc, a lifting component, etc. The working device of the present utility model can also be other functional devices, such as a sweeper, and the work execution mechanism 3 is used to perform corresponding cleaning functions.
[0061] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
