[0066] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.
[0067] Example 1:
[0068] like Figures 1-6 As shown, this utility model provides a lifting structure for a juicer, including a motor 100; a lower squeezing head 200, the top of which is used to contact the fruits and vegetables to be juiced; a transmission mechanism 300, the input end of which is connected to the output end of the motor 100, and the output end of which is connected to the input end of the lower squeezing head 200, and the transmission mechanism 300 can drive the lower squeezing head 200 to move up and down along the axial direction; the transmission mechanism 300 includes a transmission shaft 301, which is connected to the output end of the motor 100 and can rotate synchronously with the motor 100; and a worm gear 302, which is sleeved on the transmission shaft 301. The worm gear 302 is mounted on a 01-axis and can rotate synchronously with the transmission shaft 301, and can move up and down relative to the transmission shaft 301. The output end of the worm gear 302 is connected to the bottom end of the lower extrusion head 200. A first fixed shaft 303 and a second fixed shaft 304 are radially arranged relative to the axis of the worm gear 302, located on opposite sides of the worm gear 302. The first fixed shaft 303 and the second fixed shaft 304 are vertically offset along the axis of the worm gear 302 and are adapted to fit within the helical groove 3021 of the worm gear 302 to achieve the axial reciprocating motion of the worm gear 302. Specifically, the output end of the motor 100 can rotate clockwise and counterclockwise to achieve the axial reciprocating motion of the worm gear 302; the first fixed shaft 303 and the second fixed shaft 304 are pins. In some embodiments, the lifting structure of the juicer includes a housing 800, with the drive shaft 301 arranged opposite to it at the middle of the housing 800, i.e., the central axis of the drive shaft 301 coincides with the central axis of the housing 800; a spiral groove 3021 is provided on the outer wall of the lower half of the worm gear 302; a through hole 801 is provided at the top of the housing 800, through which the upper half of the worm gear 302 can pass; and a first sealing ring 802 is provided on the housing 800 at the through hole 801. Using the above scheme, the rotational motion of the worm gear 302 is converted into linear lifting motion through the cooperation of two staggered first fixed shafts 303 and second fixed shafts 304 and the spiral groove 3021 of the worm gear 302, thereby realizing the lifting motion of the lower extrusion head 200. This achieves complex motion with the simplest structure, saving production costs. In some embodiments, a sleeve 305 is further included, which is fixedly disposed outside the worm 302; the sleeve 305 is provided with the first fixed shaft 303 and the second fixed shaft 304 on opposite sides of the worm 302.
[0069] In some embodiments, a plurality of mounting shafts 803 are provided at the top end of the housing 800 and are wound around the sleeve 305. The bottom end of the mounting shaft 803 is connected to a fixing seat 804. The mounting shaft 803 has a shaft portion 8031 with a small shaft diameter near the fixing seat 804. The outer wall of the sleeve 305 is provided with a mounting sleeve 3058 that is sleeved on the shaft portion 8031. Furthermore, an elastic member 805 is provided between the base and the mounting sleeve 3058. The elasticity of the elastic member 805 keeps the mounting sleeve 3058 against the connection between the mounting shaft 803 and the shaft portion 8031. By employing the above-described scheme, the first fixed shaft 303 and the second fixed shaft 304 are installed via the sleeve 305, ensuring the parallelism and positional accuracy of the axes and facilitating assembly and disassembly. Simultaneously, mold production is simplified, increasing production capacity. Furthermore, the elastic element 805 can compensate for assembly errors between the first fixed shaft 303 and the second fixed shaft 304 and the helical groove 3021, ensuring the continuity of misaligned meshing and further absorbing vibrations to prevent the worm gear 302 from jamming due to unilateral force, thus ensuring the smoothness of the worm gear 302's lifting and lowering movements. In some embodiments, the first fixed shaft 303 and the second fixed shaft 304 can rotate radially around the worm gear 302. This radial rotation of the first fixed shaft 303 and the second fixed shaft 304 reduces sliding friction between them and the helical groove 3021, making the lifting and lowering movements of the worm gear 302 smoother. In some embodiments, the sleeve 305 is provided with a first mounting portion 3051 for mounting the first fixed shaft 303 and a second mounting portion 3052 for mounting the second fixed shaft 304 on opposite sides of the worm gear 302; and the first mounting portion 3051 and the second mounting portion 3052 are arranged vertically offset along the axis of the worm gear 302. In some embodiments, the first mounting portion 3051 includes a first shaft hole 3051a for mounting the first fixed shaft 303, and the second mounting portion 3052 includes a second shaft hole 3052a for mounting the second fixed shaft 304. In some embodiments, a first limiting member 3053 for restricting the radial movement of the first fixed shaft 303 is provided on the outer side of the first mounting portion 3051, and a second limiting member 3054 for restricting the radial movement of the second fixed shaft 304 is provided on the outer wall of the second mounting portion 3052. By adopting the above solution, the first limiting member 3053 and the second limiting member 3054 can prevent the first fixed shaft 303 and the second fixed shaft 304 from shifting and causing meshing failure, which helps to maintain the transmission accuracy during long-term use.
[0070] In some embodiments, the sleeve 305 has a cavity 3055 extending through the top and bottom ends of the sleeve 305 in the axial direction. Furthermore, the top end of the sleeve 305 is provided with a first trigger switch 3056 for limiting the maximum upward movement of the worm gear 302, and the bottom end of the sleeve 305 is provided with a second trigger switch 3057 for limiting the maximum downward movement of the worm gear 302. Specifically, when the worm gear 302 moves upward to the top of its lower half and triggers the first trigger switch 3056, the worm gear 302 is at its maximum upward movement and stops rising; when the worm gear 302 moves downward to its bottom end and triggers the second trigger switch 3057, the worm gear 302 is at its maximum downward movement and stops falling. By adopting the above scheme, the setting of the first trigger switch 3056 and the second trigger switch 3057 can accurately control the upper and lower movement limits of the worm gear 302, avoid excessive movement, prevent the worm gear 302 from exceeding the design stroke range, protect the transmission mechanism 300 and the lower extrusion head 200, realize automatic control, reduce manual intervention, and improve the convenience of operation.
[0071] In some embodiments, a reduction gear set 400 is connected to the output end of the motor 100, and the output end of the reduction gear set 400 is connected to the drive shaft 301.
