[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5 As shown, the fully automatic, wash-free blender of this utility model includes a base 1. The top of the base 1 has a positioning groove 26 and a placement groove 27. A stirring drum 2 is fitted inside the positioning groove 26. A control seat 28 is fixedly installed at the bottom of the stirring drum 2. A rotating shaft 6 is rotatably connected to the bottom of the inner cavity of the stirring drum 2. A blade 7 is fixedly connected to the rotating shaft 6. A top cover 3 is hinged to the top of the stirring drum 2. A rinsing device is provided at the bottom of the top cover 3. A water inlet pipe 21 is fixedly connected to the rinsing device. A handle 4 is fixedly connected to the outer wall of the stirring drum 2. A water tank 5 is fitted inside the placement groove 27. An installation cavity 8 is provided inside the base 1. A water pump 9 is fixedly installed inside the installation cavity 8. A water pump 9 is connected to a water suction pipe 10 and a water delivery pipe 11. The end of the water suction pipe 10 away from the water pump 9 is connected to the bottom of the inner cavity of the water tank 5. A quick-connect assembly is provided between the water delivery pipe 11 and the water inlet pipe 21. This application takes into account that traditional automatic self-cleaning blenders typically require filling the mixing container with water, closing the lid, and turning on the power. The high-speed rotation of the mixing blades agitates the water in the container, achieving self-cleaning. However, this cleaning method cannot completely clean the mixing blades when dealing with viscous beverages such as sesame paste. After cleaning, residues are easily left on the surface and in the crevices of the mixing blades, requiring manual re-cleaning. Therefore, by installing a water tank 5 on the base 1 in conjunction with a water pump 9, water can be supplied to the rinsing device, allowing the rinsing device to directly spray and rinse the high-speed rotating blades 7. This not only improves the removal of stains and avoids residues remaining on the blades 7 after cleaning, but also eliminates the need for manual re-cleaning, reducing workload. During operation, first open the cover of water tank 5 and fill water tank 5 with water. Then turn on the power supply on control base 28, so that the rotating shaft 6 drives the blade 7 to start rotating. Then start water pump 9. Through water pump 9, in conjunction with water suction pipe 10, water delivery pipe 11 and water inlet pipe 21, water can be continuously pumped into the flushing device to flush the rotating blade 7 and enhance the flushing effect.
[0018] The flushing device includes a spray plate 23 and a nozzle 24. The bottom of the top cover 3 is inlaid with the spray plate 23, and the nozzles 24 are evenly installed on the bottom of the spray plate 23. The coverage area of the nozzles 24 is adapted to the blade 7. The water inlet pipe 21 is connected to the inner cavity of the spray plate 23. The nozzle 24 is provided with a spherical protrusion, and a ball bearing 25 is provided inside the spherical protrusion of the nozzle 24; During operation, the spray nozzles 24 are evenly arranged on the spray plate 23, allowing water to be sprayed out from multiple nozzles 24 to rinse the blade 7 from all directions. When the water passes through the ball bearings 25 inside the nozzle 24, the water will drive the ball bearings 25 to rotate around in the spherical protrusion of the nozzle 24 and collide with the inner wall of the spherical protrusion, making the water flow sprayed from the nozzle 24 produce more complex flow and disturbance, no longer a straight spray, changing the angle and speed of the water sprayed from the nozzle 24, so that the water can better rinse the blade 7.
[0019] The quick-connect assembly includes a U-shaped boss 12, a first insertion tube 13, and a second insertion tube 17. The top of the base 1 is fixedly connected to the U-shaped boss 12, which is adapted to the handle 4. The top of the U-shaped boss 12 is inlaid with the first insertion tube 13. A mounting plate 14 is fixedly connected to the bottom of the inner cavity of the first insertion tube 13. A sealing element 15 is slidably connected to the mounting plate 14. A spring 16 is fixedly connected between the sealing element 15 and the mounting plate 14. The water supply pipe 11 is away from water. One end of the pump 9 is connected to the bottom end of the first connector 13. The bottom end of the handle 4 is inlaid with the second connector 17. The top of the inner cavity of the second connector 17 is fixedly connected to the second mounting plate 18. The second sealing element 19 is slidably connected to the second mounting plate 18. The second spring 20 is fixedly connected between the second sealing element 19 and the second mounting plate 18. The end of the water inlet pipe 21 away from the spray plate 23 passes through the handle 4 and is connected to the top of the second connector 17. Both the first mounting plate 14 and the second mounting plate 18 are provided with through grooves. The inner wall of the first insertion tube 13 and the inner wall of the second insertion tube 17 are both provided with tapered surfaces. The first sealing element 15 and the second sealing element 19 are both composed of a limiting rod and a valve core. The valve core is adapted to the tapered surfaces on the first insertion tube 13 and the second insertion tube 17. During operation, when the mixing drum 2 needs to be self-cleaned, it is placed in the positioning groove 26, and the handle 4 is then in contact with the U-shaped protrusion. During this process, the rubber ring at the top of the insertion pipe 13 fits against the bottom of the insertion pipe 2 17, ensuring a tight seal during the fit. At the same time, the limiting rod on the sealing element 15 and the limiting rod on the sealing element 2 19 fit together and press against each other, causing the valve cores on both sealing element 15 and sealing element 2 19 to move away from their corresponding conical surfaces. Spring 16 and spring 2... When the water in the water supply pipe 11 is squeezed, the water enters the insertion pipe 13 through the through groove on the mounting plate 14, and then enters the insertion pipe 27 through the two valve cores. Finally, it enters the water inlet pipe 21 through the through groove on the mounting plate 28. When the cleaning is completed and the stirring drum 2 moves away from the positioning groove 26, the sealing element 15 and the sealing element 29 are reset under the elastic force of the spring 16 and the spring 20, respectively, so as to seal the insertion pipe 13 and the insertion pipe 27 and prevent the entry of external impurities.
[0020] The top of the top cover 3 and the top of the handle 4 are both fixedly connected with sleeves, which are adapted to the water inlet pipe 21, which is a flexible hose. During operation, by setting pipe sleeves 22 on the top cover 3 and handle 4, the exposed water inlet pipe 21 can be accommodated and hidden. This not only protects the water inlet pipe 21 from external wear, but also enhances its appearance.
[0021] Working principle: When the mixing drum 2 needs to be self-cleaned, the mixing drum 2 is placed in the positioning groove 26, and the handle 4 is then attached to the U-shaped protrusion. During this process, the rubber ring on the top of the insertion pipe 13 is attached to the bottom of the insertion pipe 2 17, ensuring the sealing during the attachment. At the same time, the limiting rod on the sealing element 15 and the limiting rod on the sealing element 2 19 are attached and squeezed against each other, so that the valve cores on the sealing element 15 and the sealing element 2 19 are far away from the corresponding conical surface. The insertion pipe 13 is connected to the insertion pipe 2 17. The cover of the water tank 5 is opened, and the water tank 5 is filled with water. The power supply on the control seat 28 is turned on, so that the rotating shaft 6 drives the blade 7 to start rotating. Then the water pump 9 is turned on. Through the water pump 9, in conjunction with the water suction pipe 10, the water delivery pipe 11 and the water inlet pipe 21, water can be continuously pumped into the water spray plate 23. By the evenly distributed nozzles 24 on the water spray plate 23, water can be sprayed out from multiple nozzles 24 to rinse the blade 7 in all directions.
