[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a stirring mechanism, including a shell 1, an outer wall of the shell 1 is fixedly connected to a fixing ring 2, and the bottom end of the shell 1 is fixedly connected to a base 3, the bottom end of the base 3 is movably connected to a shock absorbing mechanism 4, the inside of the shell 1 is fixedly connected to a servo motor 5, and the output end of the servo motor 5 is fixedly connected to a rotating rod 6, one end of the rotating rod 6 is fixedly connected to a stirring component 7, and a cleaning mechanism 8 is provided on the opposite side of the stirring component 7 and the shell 1.
[0024] When the motor and the stirring assembly 7 are working, lateral and vertical vibrations are likely to occur. At this time, the outer shell 1 drives the shock absorbing mechanism 4 to move up and down through the base 3. At the same time, since the shock absorbing mechanism 4 repel each other, the device is damped. If the outer shell 1 is subjected to lateral vibration, the movable seat 403 drives the telescopic rod 10 to perform telescopic movement inside the bracket 9, and the spring 11 is retracted and extended, thereby performing lateral and vertical damping on the outer shell 1, which is beneficial for the shock absorbing mechanism 4 to reduce the vibration generated by the submersible mixer and extend the service life of the mixer. Finally, when the rotating rod 6 drives the stirring assembly 7 to rotate, the rotating rod 6 also drives the cleaning mechanism 8 to rotate, so that the cleaning mechanism 8 rotates and cuts the weeds in the water, which is beneficial for the blade 801 to cut the weeds in the water and prevent the weeds from being entangled in the stirring assembly 7, thereby avoiding damage to the device.
[0025] like Figure 1-3As shown, the shock absorbing mechanism 4 includes a shock absorbing block 401, a spring 1 402, a movable seat 403, a magnet 1 404 and a magnet 2 405. The bottom end of the shock absorbing block 401 is fixedly connected to the bottom end of the spring 1 402, and both ends of the shock absorbing block 401 are slidably connected to the inside of the movable seat 403. The bottom end of the magnet 2 405 is fixedly connected to the top end of the movable seat 403, and the magnet 2 405 is located below the magnet 1 404. The top end of the shock absorbing block 401 is fixedly connected to the bottom end of the base 3, and the bottom end of the base 3 is fixedly connected to the bottom end of the base 3. The ends are fixedly connected to the two magnets 404 respectively, the bottom end of the movable seat 403 is slidably connected to the bracket 9, the shock absorbing block 401 is located on the opposite side of the two magnets 404, and the magnet 404 and the magnet 2 405 repel each other, the two ends of the movable seat 403 are fixedly connected to the two telescopic rods 10 respectively, the outer wall of the telescopic rod 10 is provided with a spring 2 11, and the two ends of the spring 2 11 are fixedly connected to the movable seat 403 and one end of the bracket 9 respectively, and one end of the telescopic rod 10 is movably connected to the inside of the bracket 9.
[0026] When the motor and the stirring assembly 7 are working, lateral and vertical vibrations are likely to occur. At this time, the outer shell 1 drives the shock absorbing block 401 to move up and down through the base 3, so that the shock absorbing block 401 performs shock absorbing movement through the spring 1 402. At the same time, since the magnet 1 404 and the magnet 2 405 repel each other, the device is damped. If the outer shell 1 is subjected to lateral vibration, the movable seat 403 drives the telescopic rod 10 to perform telescopic movement inside the bracket 9, and the spring 2 11 is extended and retracted, thereby performing lateral and vertical shock absorption on the outer shell 1, which is beneficial for the shock absorbing mechanism 4 to reduce the vibration generated by the submersible mixer and extend the service life of the mixer.
[0027] like Figure 1 and Figure 4 As shown, the cleaning mechanism 8 includes a blade 801, a linkage ring 802 and a sealing ring 803. The outer wall of the linkage ring 802 is fixedly connected to one end of the plurality of blades 801, and one end of the linkage ring 802 is movably connected to one end of the sealing ring 803. One end of the linkage ring 802 is fixedly connected to one end of the stirring assembly 7, and the end of the sealing ring 803 away from the linkage ring 802 is fixedly connected to one end of the outer shell 1. The outer wall of the rotating rod 6 is fixedly connected to the inside of the linkage ring 802.
[0028] When the rotating rod 6 drives the stirring assembly 7 to rotate, the rotating rod 6 drives the blade 801 to rotate through the linkage ring 802, so that the linkage ring 802 rotates on the sealing ring 803. The sealing ring 803 seals the connection between the shell 1 and the linkage ring 802, thereby preventing water from entering the interior of the shell 1, which is beneficial for the blade 801 to cut weeds in the water and prevent weeds from being entangled on the stirring assembly 7, thereby avoiding damage to the device.
[0029] Working principle: When the motor and the stirring assembly 7 are working, lateral and vertical vibrations are likely to occur. At this time, the outer shell 1 drives the shock-absorbing block 401 to move up and down through the base 3, so that the shock-absorbing block 401 performs shock-absorbing movement through the spring 1 402. At the same time, since the magnet 1 404 and the magnet 2 405 repel each other, the device is damped. If the outer shell 1 is subjected to lateral vibration, the movable seat 403 drives the telescopic rod 10 to perform telescopic movement inside the bracket 9, and the spring 2 11 is retracted, thereby performing lateral and vertical shock absorption on the outer shell 1. Finally, when the rotating rod 6 drives the stirring assembly 7 to rotate, the rotating rod 6 drives the blade 801 to rotate through the linkage ring 802, so that the linkage ring 802 rotates on the sealing ring 803. The sealing ring 803 seals the connection between the outer shell 1 and the linkage ring 802, thereby preventing water from entering the interior of the outer shell 1, thereby allowing the blade 801 to cut off weeds in the water.
