[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] like Figure 1-8 As shown, a self-cleaning juicer includes a base 1 with a control component 2. A stirring cup 3 is detachably mounted on the base 1. A first cover 4, which contains the stirring cup 3, is also detachably mounted on the base 1. The first cover 4 has a cleaning mechanism 5 for cleaning the inside of the stirring cup 3. The cleaning mechanism 5 is housed inside the stirring cup 3 and is connected to a stirring device 6 located at the bottom of the stirring cup 3.

[0038] The base 1 serves as the basic support component of the entire juicer and has a built-in control component 2 for controlling the operating status of the entire juicer, such as controlling the start, stop and speed of the drive motor 64. It provides a stable installation position for the blending cup 3, ensuring that the blending cup 3 can be placed stably on the juicer during juicing and cleaning.

[0039] The blending cup 3 is the main container for juicing, used to hold ingredients and juice. A blending device 6 is installed at its bottom to crush and blend the ingredients, thus achieving the juicing function. The detachable design of the blending cup 3 facilitates cleaning and replacement by the user, while also providing space for the installation and operation of the cleaning mechanism 5.

[0040] Furthermore, the cleaning mechanism 5 includes a guide post 51 and a cleaning disc 52 slidably mounted on the guide post 51 for cleaning the inner wall of the stirring cup 3. The cleaning disc 52 includes a disc body 53 and a cleaning ring 54 disposed on the outer wall of the edge of the disc body 53.

[0041] The cleaning ring 54 is detachably mounted on the cleaning tray 52, and the cleaning ring 54 is a soft and elastic ring-shaped component. Several brushes are also provided on the outer edge of the cleaning ring 54.

[0042] The cleaning disc 52 moves up and down reciprocally under the drive of the guide column 51. The cleaning ring 54 and brush on the edge of the disc 53 come into contact with the inner wall of the mixing cup 3, and clean the inner wall of the mixing cup 3 by wiping and brushing.

[0043] Furthermore, the guide post 51 is disposed through the center of the disc body 53, and the center of the disc body 53 has an opening 55 for accommodating the guide post 51.

[0044] The outer wall of the guide post 51 is provided with a guide groove 511, and the inner wall of the opening 55 is provided with a slider 56 for sliding connection in the guide groove 511. The slider 56 is slidably disposed in the closed and arc-shaped guide groove 511. When the guide post 51 rotates, the cleaning disc 52 moves in the vertical direction in conjunction with it.

[0045] The slider 56 of the cleaning disc 52 cooperates with the guide groove 511 of the guide post 51 to ensure that the cleaning disc 52 can move along a predetermined trajectory and direction, thereby improving the cleaning efficiency and effect.

[0046] In this embodiment, the guide post 51 is a rotatable columnar component, and a guide groove 511 is formed on the guide post 51. The groove path of the guide groove 511 determines the moving direction of the cleaning disc 52, such as... Figure 7 As shown, the guide groove 511 is a closed groove set on the outer wall of the guide post 51. When the guide post 51 rotates, the slider 56, which is slidably connected inside it, slides within the guide groove 511 under force. Since the guide groove 511 is a closed groove, the slider 56 can move back and forth within the guide groove 511. Therefore, when the guide post 51 rotates, the cleaning plate 52 can be driven to move in the vertical direction by utilizing the cooperation between the guide groove 511 and the slider 56, thereby achieving the effect of repeatedly cleaning the inner wall of the stirring cup 3.

[0047] Furthermore, a sealing cover 7 is installed on the top of the first cover 4, and a connection port 8 for connecting the guide post 51 is opened at the bottom of the sealing cover 7. A limit groove 9 is opened on the inner wall of the connection port 8.

[0048] The top of the guide post 51 is provided with a first connecting part 512 for rotatably installed in the connecting port 8, and a limiting ring 513 that engages in the limiting groove 9 is provided on the outer wall of the first connecting part 512.

[0049] The bottom of the sealing cover 7 is also fixedly installed with a positioning slide rod 10 that passes through the cleaning tray 52.

[0050] The positioning slide rod 10 passes through the cleaning disc 52, restricting the horizontal freedom of the cleaning disc 52 so that it can only move up and down along the axis of the slide rod. This can prevent the cleaning disc 52 from tilting or deviating during the movement, thereby ensuring the smoothness and consistency of the cleaning action. The positioning slide rod 10 cooperates with the guide post 51 to further optimize the movement path of the cleaning disc 52, so that it can move up and down more smoothly in the mixing cup 3.

[0051] Furthermore, the guide post 51 is a hollow columnar component, and a second connecting part 514 for engaging with the stirring device 6 is provided on the inner wall of the guide post 51 near the bottom. The second connecting part 514 is a groove formed in the inner wall of the guide post 51.

[0052] Furthermore, the stirring device 6 includes a mounting base 61 installed at the bottom of the stirring cup 3, and a pulverizing mechanism 62 installed on the mounting base 61. The pulverizing mechanism 62 includes a pulverizing blade 63 and a drive motor 64. The pulverizing blade 63 is exposed at the top of the mounting base 61, and the drive motor 64 is built into the mounting base 61, with the transmission end of the drive motor 64 connected to the pulverizing blade 63.

[0053] Furthermore, the top of the crushing head 63 is also equipped with a connector 65 for engaging with the second connecting part 514, and the outer wall of the connector 65 is provided with a plurality of limiting blocks 66 for engaging within the second connecting part 514.

[0054] In some embodiments, the cross-section of the second connecting part 514 is polygonal, consistent with the cross-sectional shape of the connector 65; the guide post 51 engages with the connector 65 of the stirring device 6 through the second connecting part 514 on its inner wall, transmitting the power of the stirring device 6 to the cleaning mechanism 5. When the drive motor 64 of the stirring device 6 is working, the crushing blade 63 rotates, and through the cooperation between the connector 65 and the second connecting part 514, it drives the guide post 51 to rotate, thereby realizing the movement of the cleaning mechanism 5, so that the cleaning disc 52 can move up and down in the stirring cup 3 to complete the cleaning work.

[0055] Furthermore, the base 1 is provided with several grooves 11 at the connection between it and the first cover 4. The outer wall of the base 1 near the lower part of the first cover 4 is provided with a positioning protrusion 12. The inner wall of the first cover 4 is provided with a first positioning groove 13 and a second positioning groove 14 corresponding to the positioning protrusion 12 for accommodating the positioning protrusion 12.

[0056] A button 15 for controlling the working state of the drive motor 64 is provided at the bottom of the groove 11, and a top block 16 for pressing the button 15 is also provided at the lower part of the inner wall of the first cover 4.

[0057] The different working modes of the juicer can be switched by button 15, such as juicing mode and cleaning mode. In cleaning mode, button 15 triggers the motor to run at a specific speed, driving the cleaning mechanism 5 to work. The top block 16 is installed on the inner wall of the first cover 4. When the first cover 4 is assembled with the base 1, the top block 16 will press the button 15 on the base 1, thereby starting or adjusting the working state of the drive motor 64. The design of the top block 16 allows the user to automatically trigger the start or stop of the drive motor 64 or change the working mode of the drive motor 64 without manually operating the button 15 when installing or removing the first cover 4.

[0058] Furthermore, the second positioning groove 14 is located above the first positioning groove 13. The vertical distance between the center of the first positioning groove 13 and the second positioning groove 14 is equal to the thickness of the part of the button 15 exposed in the groove 11. When the positioning protrusion 12 is engaged in the second positioning groove 14, the top block 16 presses the button 15 and adjusts the speed of the drive motor 64.

[0059] When the first cover 4 is installed on the base 1, the installation of the first cover 4 can be completed by the engagement of the positioning protrusion 12 with the first positioning groove 13. If it is necessary to start the cleaning mechanism 5, the first cover 4 is pressed down further so that the positioning protrusion 12 is engaged in the second positioning groove 14. At this time, the top block 16 presses several buttons 15 set on the base 1. When several buttons 15 are pressed at the same time, the working mode of the drive motor 64 is switched to slow mode. When the first cover 4 is pressed down, the second connecting part 514 at the bottom of the guide column 51 is engaged with the connecting head 65 of the crushing blade 63. In this state, the crushing blade 63 can be driven to rotate by starting the drive motor 64 to rotate slowly, thereby linking the guide column 51 and driving the cleaning plate 52 to clean the inner wall of the mixing cup 3.

[0060] Furthermore, a gripping component 17 is fixedly provided on the outer side of the mixing cup 3, and an avoidance groove 18 is provided on the outer side wall of the first cover 4 to avoid the gripping component 17. The gripping component 17 includes a gripping connection part 19 connected to the outer wall of the mixing cup 3, and also includes a handle 20 fixedly provided on the gripping connection part 19. The avoidance groove 18 engages with the gripping connection part 19.

[0061] In this embodiment, the automatic cleaning function is achieved through the integrated cleaning mechanism 5. The core of this function is to use the power of the stirring device 6 to drive the cleaning mechanism 5. Specifically, the drive motor 64 of the stirring device 6 engages with the second connecting part 514 inside the guide column 51 through the connector 65 at the top of the crushing head 63, transmitting power to the cleaning mechanism 5. When the motor starts, the crushing head 63 rotates while driving the guide column 51 to rotate. The guide groove 511 on the guide column 51 cooperates with the slider 56 on the cleaning disc 52, so that the cleaning disc 52 can move up and down in the vertical direction. The edge of the disc body 53 of the cleaning disc 52 is equipped with a soft elastic cleaning ring 54 and a brush, which cleans the inner wall of the stirring cup 3 by wiping and brushing. In addition, the first cover 4 and the base 1 are connected by the positioning protrusion 12 and the first positioning groove 13 and the second positioning groove 14. The top block 16 presses the button 15 on the base 1 to adjust the working mode of the drive motor 64, that is, its speed, thereby switching between juicing and cleaning modes.

[0062] During use, the user installs the mixing cup 3 onto the base 1 and covers it with the first cover 4. When juicing is needed, the positioning protrusion 12 engages in the first positioning groove 13, and the top block 16 does not press the button 15. The drive motor 64 runs at normal speed, driving the pulverizing head 63 to pulverize the ingredients. When cleaning is needed, the user presses the first cover 4, causing the positioning protrusion 12 to engage in the second positioning groove 14. The top block 16 presses the button 15, and the drive motor 64 switches to slow speed mode. At this time, the guide post 51 engages with the pulverizing head 63 connector 65. The slow rotation of the motor drives the guide post 51 to rotate. Through the cooperation of the guide groove 511 and the slider 56, the cleaning disc 52 moves up and down inside the mixing cup 3. The cleaning ring 54 and the brush thoroughly wipe and clean the inner wall of the mixing cup 3. After cleaning, the first cover 4 is reset, causing the positioning protrusion 12 to engage in the first positioning groove 13. The motor returns to normal speed. At this time, the cleaning mechanism 5 can be disassembled to complete the entire cleaning process.

[0063] The automatic cleaning function of this invention greatly saves users' time and effort. Users do not need to manually disassemble the mixing cup 3 for cleaning; they only need to start the cleaning program to complete the cleaning work. Secondly, the design of the cleaning mechanism 5 can effectively clean stubborn stains on the inner wall of the mixing cup 3, such as juice crystals and food residues, ensuring that the mixing cup 3 is always clean and hygienic, and extending its service life. In addition, the function switching is achieved through a simple mechanical structure, which improves the reliability and safety of the equipment, while simplifying the operation process and enhancing the user experience.

[0064] The specific embodiments of the invention have been described in detail above, but these are merely examples. The invention is not limited to the specific embodiments described above. Those skilled in the art should understand that the embodiments and descriptions in the specification are only illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
