Description

Technical Field

[0001] This utility model relates to the field of lawn mowing robot technology, and more specifically, to a lawn mowing robot with self-cleaning function. Background Technology

[0002] A lawnmower is a device specifically designed for automatically mowing lawns. These robots can work autonomously, reducing the need for manual lawn maintenance. Modern lawnmowers are typically equipped with intelligent navigation systems that can automatically identify lawn boundaries and start and stop according to a preset schedule. Some advanced models also support remote control and monitoring via a smartphone app. Most lawnmowers move across the lawn in random or systematic patterns. They are powered by built-in batteries and automatically return to a charging station when the battery is low. Users can set specific times for the lawnmower to start working automatically, which helps keep the lawn always clean.

[0003] Existing lawn mowing robots use different navigation technologies to cover the entire lawn surface, enabling them to navigate and operate in a more systematic way. Lawn mowing robots can automatically return to pre-set charging stations for charging, relying on radio signals between the robot and the charging station for precise positioning. Lawn mowing robots are equipped with rotating blades located at the bottom of the body, which effectively cut grass blades by rotating at high speed. Their cutting method tends to frequently but in small amounts, which helps promote healthy lawn growth. Many lawn mowing robots support programming and monitoring via smartphone apps or other remote control methods.

[0004] In practical use, existing lawnmowers accumulate grass clippings, dirt, and other debris, which adhere to the blades. If the grass clippings and debris are not cleaned for a long time, it will affect the cutting effect. Therefore, a lawnmower with a self-cleaning function is proposed. Utility Model Content

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a lawnmower robot with a self-cleaning function, including a lawnmower robot shell 1, a lawnmower component 2 and a cleaning component 3. The lawnmower robot shell 1 has an installation cavity 101. The lawnmower component 2 is installed in the installation cavity 101 and includes two electric push rods 201 that are symmetrically fixedly connected to the top of the installation cavity 101. A moving plate 202 is fixedly connected to the lower end of the electric push rod 201. A drive motor 203 is fixedly connected to the middle of the upper surface of the moving plate 202. A cutting blade 205 is fixedly connected to the output shaft end of the drive motor 203 through the moving plate 202.

[0031] Specifically, the movable plate 202 is circular and moves inside the mounting cavity 101, and a groove 204 is provided on the outer surface of the movable plate 202.

[0032] Furthermore, when the lawnmower robot is running, the electric push rod 201 adjusts the position of the moving plate 202 according to the height of the grass, so that the cutting blade 205 can maintain the optimal cutting height to meet different lawn mowing needs. Then, the drive motor 203 is started to drive the cutting blade 205 to rotate and perform lawn mowing work.

[0033] The cutting blade 205 is directly responsible for mowing the lawn. It requires high hardness, sharpness and easy replacement. It is usually made of steel that has been specially treated to enhance wear resistance. The moving plate 202 serves as a support platform, supporting the drive motor 203 and the cutting blade 205, and can move freely within the mounting cavity 101. It is made of wear-resistant and corrosion-resistant materials such as engineering plastics or lightweight metals.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The cleaning component 3 is installed inside the lawn mower shell 1. It includes two branch pipes 301 fixedly connected to the inner cavity of the lawn mower shell 1. One end of the branch pipe 301 located inside the mounting cavity 101 is connected to a nozzle 302, and the other end of the branch pipe 301 located outside the lawn mower shell 1 is connected to a main pipe 303.

[0036] Specifically, the groove 204 is directly opposite the nozzle 302. There are two nozzles 302, which are set at an angle and symmetrically arranged on the upper and lower sides of the cutting blade 205. A water pump 304 is installed on the main pipe 303. One side of the water pump 304 is fixedly connected to the outer surface of the lawnmower shell 1. A universal connector 305 is connected to the upper end of the main pipe 303. A piston 306 is movably connected to the inner cavity of the universal connector 305. The piston 306 is made of elastic material. A sealing gasket is fixedly connected to the upper surface of the moving plate 202.

[0037] Furthermore, after the mowing operation is completed, the electric push rod 201 is activated to drive the cutting blade 205 back to its original position. At this time, the two nozzles 302 are symmetrically located on the upper and lower sides of the cutting blade 205. They are connected to the external tap water pipe through the universal connector 305. The water pump 304 is activated to draw water in through the main pipe 303 and distribute it to the two branch pipes 301. Finally, the water is sprayed out from the nozzles 302. The two inclined nozzles 302 are located on the upper and lower sides of the cutting blade 205 respectively, ensuring that the blade area can be fully covered and effectively washing away the grass clippings and other dirt adhering to the cutting blade 205.

[0038] The nozzle 302 is aligned with the groove 204 on the outer surface of the moving plate 202 to prevent the moving plate 202 from colliding with the nozzle 302 during movement. The upper surface of the moving plate 202 abuts against the inner wall of the mounting cavity 101 through a sealing gasket, which can prevent the flushing wastewater from entering the area of ​​the drive motor 203 and the electric push rod 201. When the universal connector 305 is not connected to the external tap water pipe, it is blocked by the piston 306 to prevent impurities from entering the main pipe 303. The cleaning process is automated, reducing the need for manual intervention.

[0039] Working principle: During operation, when the lawnmower robot is running, the electric push rod 201 adjusts the position of the moving plate 202 according to the height of the grass, ensuring that the cutting blade 205 maintains the optimal cutting height to meet different mowing needs. Then, the drive motor 203 is activated to rotate the cutting blade 205, performing lawn mowing. After mowing is complete, the electric push rod 201 is activated again to return the cutting blade 205 to its original position. At this point, the two nozzles 302 are symmetrically positioned on the upper and lower sides of the cutting blade 205, connected to an external water pipe via a universal connector 305. The water pump 304 is activated to draw water through the main pipe 303 and distribute it to the two branch pipes 301. Finally, the water is sprayed out from the nozzle 302. The two inclined nozzles 302 are located on the upper and lower sides of the cutting blade 205 respectively, ensuring that the blade area can be fully covered and effectively washing away grass clippings and other dirt adhering to the cutting blade 205. The nozzles 302 are aligned with the grooves 204 on the outer surface of the moving plate 202 to prevent the moving plate 202 from colliding with the nozzles 302 when it moves. The upper surface of the moving plate 202 abuts against the inner wall of the mounting cavity 101 through a sealing gasket, which can prevent the flushing wastewater from entering the area of ​​the drive motor 203 and the electric push rod 201. When the universal connector 305 is not connected to the external tap water pipe, it is blocked by the piston 306 to prevent impurities from entering the main pipe 303.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
