Description
Technical Field
[0001] This utility model relates to the field of drive motor technology, and in particular to a motor anti-reverse structure and a smoothie machine. Background Technology
[0002] A smoothie maker is a kitchen appliance that transforms liquid beverages into a smoothie with semi-melted, semi-fine ice particles. The core components of a smoothie maker are an ice bucket, an evaporator, a stirring assembly, and an ice dispensing assembly; among them, the stirring assembly is mainly used for scraping and pushing ice.
[0003] For example, Chinese invention application CN119353841A discloses a smoothie machine that can improve the efficiency of smoothie making. It includes a housing with a smoothie bucket mounting section, on which a smoothie bucket is mounted. A rotating spiral cutter holder is installed inside the smoothie bucket, connected to a drive motor. The drive motor drives the spiral cutter holder to rotate, and the outer end of the smoothie bucket forms a smoothie outlet. In the above-mentioned prior art smoothie machine, when the drive motor rotates forward, it pushes the smoothie inside the smoothie bucket out through the smoothie outlet. If the drive motor rotates in reverse, the smoothie cannot be discharged normally. Therefore, a motor anti-reverse structure is needed to avoid the impact caused by motor reversal.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a motor anti-reverse structure and a smoothie maker.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides a motor anti-reverse structure, including a transmission gear, a rotating gear, and a fixed base connected to the motor output shaft. The transmission gear meshes with the rotating gear. The fixed base is provided with an arc-shaped groove and a blocking part. The central shaft of the rotating gear can roll within the arc-shaped groove, and the blocking part is disposed adjacent to the arc-shaped groove. When the motor rotates forward, the central shaft moves towards the first end of the arc-shaped groove, and the blocking part does not contact the rotating gear. When the motor rotates in reverse, the rotating gear moves towards the second end of the arc-shaped groove until the blocking part contacts the rotating gear, thereby preventing the rotating gear from rotating.
[0008] With the above structural design, when the motor rotates forward, the blocking part does not interfere with the operation of the rotating gear. When the motor rotates in reverse, it drives the rotating gear to move closer to the second end of the arc groove until the blocking part contacts the rotating gear. The blocking part prevents the rotating gear from rotating, thus stopping the motor from rotating in reverse and effectively avoiding the impact caused by the motor continuing to rotate in reverse.
[0009] It is understood that the motor drives the output shaft to rotate. Forward rotation of the motor means the output shaft rotates clockwise, and reverse rotation means the output shaft rotates counterclockwise. When the motor rotates forward, it causes the central shaft of the rotating gear to roll near the first end of the arc-shaped groove. The blocking part does not contact the rotating gear, thus preventing interference with its operation. When the central shaft abuts against the first end of the arc-shaped groove, it rotates within the groove, allowing the motor to rotate normally forward. When the motor rotates in reverse, it causes the central shaft of the rotating gear to roll near the second end of the arc-shaped groove until the blocking part contacts the rotating gear.
[0010] According to the above scheme, the blocking part includes a fixed block and a protruding block. The protruding block is fixed on the fixed block and can be engaged in the tooth groove of the rotating gear.
[0011] As the rotating gear moves near and contacts the blocking part, the protruding block engages in the tooth groove of the rotating gear, thereby preventing the rotating gear from continuing to reverse.
[0012] According to the above scheme, it also includes an upper cover, which is fixed on the fixed base and forms a placement cavity with the fixed base, and the rotating gear and the transmission gear are disposed in the placement cavity.
[0013] By setting a top cover to form a cavity with the fixed base, the rotating gear and transmission gear are protected.
[0014] According to the above scheme, the upper cover has an arc-shaped groove on the side near the fixed seat. One end of the central shaft is inserted into the arc-shaped groove, and the other end of the central shaft is inserted into the arc-shaped groove. The rotating gear abuts against the fixed seat on the side near the fixed seat. This arrangement confines the rotating gear within the placement cavity, which helps improve the stability of the rotating gear's movement.
[0015] According to the above scheme, the transmission gear has a non-circular hole, and the connecting end of the motor output shaft is configured with a cross-sectional structure that matches the non-circular hole. The connecting end of the motor output shaft passes through the fixed seat and is inserted into the non-circular hole with an interference fit.
[0016] With the above structural design, the transmission gear is fixedly connected to the motor output shaft, and the motor output shaft drives the transmission gear to rotate synchronously.
[0017] According to the above scheme, the mounting base is fixed to the motor. This arrangement helps to improve the compactness of the structure.
[0018] According to the above scheme, the motor is a synchronous motor. The use of a synchronous motor in this invention is beneficial for improving operational stability. Furthermore, if the resistance of a synchronous motor suddenly increases during operation, its rotation direction will change; therefore, when the synchronous motor reverses and drives the rotating gear to contact the blocking part, the blocking part prevents the rotating gear from continuing to rotate, increasing the resistance to the synchronous motor, and the rotation direction of the synchronous motor will change, thus becoming forward rotation.
[0019] According to the above scheme, when the blocking part contacts the rotating gear, the central shaft of the rotating gear abuts against the second end of the arc-shaped groove. The rolling range of the central shaft can be limited by setting the length of the arc-shaped groove.
[0020] This utility model also provides a smoothie machine, including a motor, a smoothie bucket, and the aforementioned motor anti-reverse structure. The motor is connected to the transmission gear of the motor anti-reverse structure via a motor output shaft. A stirring assembly is provided inside the smoothie bucket, and the stirring assembly is drivenly connected to the motor output shaft.
[0021] According to the above scheme, it also includes a reduction gear assembly, and the motor output shaft is connected to the stirring assembly through the reduction gear assembly.
[0022] According to the above scheme, it also includes a main unit, in which the motor, the reduction gear assembly and the motor anti-reverse structure are all located. The slush bucket is located on the main unit, and the output shaft of the reduction gear assembly passes through the main unit and the slush bucket in sequence and is connected to the stirring assembly.
[0023] The beneficial effects of this utility model are as follows:
[0024] This invention features an arc-shaped groove and a blocking part on a fixed base. The central shaft of the rotating gear can roll within the arc-shaped groove. A transmission gear meshes with the rotating gear, and the motor output shaft is connected to the transmission gear. The blocking part is positioned adjacent to the arc-shaped groove. When the motor rotates forward, the blocking part does not interfere with the operation of the rotating gear. However, when the motor rotates in reverse, it drives the rotating gear to move closer to the second end of the arc-shaped groove until the blocking part contacts the rotating gear. The blocking part prevents the rotating gear from rotating, thus stopping the motor from rotating in reverse and effectively avoiding the impact caused by the motor continuing to rotate in reverse.

[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0032] like Figure 1-3 As shown, this utility model provides a motor anti-reverse structure, including a transmission gear 2, a rotating gear 3, and a fixed base 4 connected to the motor output shaft 11. The transmission gear 2 meshes with the rotating gear 3. The fixed base 4 is provided with an arc-shaped groove 41 and a blocking part 5. The central shaft 31 of the rotating gear 3 can roll in the arc-shaped groove 41. The blocking part 5 is arranged adjacent to the arc-shaped groove 41. When the motor 1 rotates forward, the central shaft 31 moves towards the first end of the arc-shaped groove 41, and the blocking part 5 does not contact the rotating gear 3. When the motor 1 rotates in reverse, the rotating gear 3 moves towards the second end of the arc-shaped groove 41 until the blocking part 5 contacts the rotating gear 3, thereby preventing the rotating gear 3 from rotating.
[0033] With the above structural design, when the motor 1 rotates forward, the blocking part 5 does not interfere with the operation of the rotating gear 3. When the motor 1 rotates in reverse, it drives the rotating gear 3 to move closer to the second end of the arc groove 41 until the blocking part 5 contacts the rotating gear 3. The blocking part 5 prevents the rotating gear 3 from rotating, thus stopping the motor 1 from rotating in reverse and effectively avoiding the impact caused by the motor 1 continuing to rotate in reverse.
[0034] It is understood that motor 1 drives the output shaft 11 to rotate. Forward rotation of motor 1 means the output shaft 11 rotates clockwise, and reverse rotation means the output shaft 11 rotates counterclockwise. When motor 1 rotates forward, it causes the central shaft 31 of the rotating gear 3 to roll near the first end of the arc-shaped groove 41. The blocking part 5 does not contact the rotating gear 3, thus preventing the blocking part 5 from interfering with the operation of the rotating gear 3. When the central shaft 31 abuts against the first end of the arc-shaped groove 41, the central shaft 31 rotates within the arc-shaped groove 41, allowing motor 1 to rotate normally forward. When motor 1 rotates in reverse, it causes the central shaft 31 of the rotating gear 3 to roll near the second end of the arc-shaped groove 41, causing the rotating gear 3 to contact the blocking part 5.
[0035] Furthermore, the blocking part 5 includes a fixing block 51 and a protruding block 52. The protruding block 52 is fixed on the fixing block 51 and can be engaged in the tooth groove of the rotating gear 3.
[0036] When the rotating gear 3 moves close to and contacts the blocking part 5, the protruding block 52 engages in the tooth groove of the rotating gear 3, thereby preventing the rotating gear 3 from continuing to reverse.
[0037] Furthermore, it also includes an upper cover 42, which is fixed to the fixed base 4 and forms a placement cavity (not shown in the figure) with the fixed base 4, and the rotating gear 3 and the transmission gear 2 are disposed in the placement cavity.
[0038] By setting the top cover 42 to form a placement cavity with the fixed base 4, the rotating gear 3 and the transmission gear 2 are protected.
[0039] Furthermore, the upper cover 42 has an arc-shaped groove (not shown in the figure) on the side near the fixed seat 4. One end of the central shaft 31 is inserted into the arc-shaped groove 41, and the other end of the central shaft 31 is inserted into the arc-shaped groove. The rotating gear 3 abuts against the fixed seat 4 on the side near the fixed seat.
[0040] The above configuration confines the rotating gear 3 within the placement cavity, which helps improve the stability of the rotation of the rotating gear 3.
[0041] Furthermore, the transmission gear 2 has a non-circular hole 21, and the connecting end 111 of the motor output shaft 11 is configured with a cross-sectional structure that matches the non-circular hole 21. The connecting end 111 of the motor output shaft 11 passes through the fixed seat 4 and is inserted into the non-circular hole 21 with an interference fit.
[0042] With the above structural arrangement, the transmission gear 2 is fixedly connected to the motor output shaft 11, and the motor output shaft 11 drives the transmission gear 2 to rotate synchronously.
[0043] Furthermore, the mounting base 4 is fixed to the motor 1. This arrangement helps to improve the compactness of the structure.
[0044] Furthermore, when the blocking part 5 contacts the rotating gear 3, the central shaft 31 of the rotating gear 3 abuts against the second end of the arc-shaped groove 41. The rolling range of the central shaft 31 can be limited by setting the length of the arc-shaped groove 41.
[0045] like Figure 4-5 As shown, this utility model also provides a smoothie machine, including a motor 1, a smoothie bucket 6 and the above-mentioned motor anti-reverse structure. The motor 1 is connected to the transmission gear 2 of the motor anti-reverse structure through the motor output shaft 11. A stirring assembly 61 is provided inside the smoothie bucket 6, and the stirring assembly 61 is connected to the motor output shaft 11.
[0046] Furthermore, it also includes a reduction gear assembly 7, through which the motor output shaft 11 is connected to the stirring assembly 61 via the reduction gear assembly 7.
[0047] Furthermore, it also includes a main unit 8, in which the motor 1, the reduction gear assembly 7 and the motor anti-reverse structure are all located. The smoothie bucket 6 is located on the main unit 8, and the output shaft of the reduction gear assembly 7 passes through the main unit 8 and the smoothie bucket 6 in sequence and is connected to the stirring assembly 61.
[0048] Furthermore, the motor 1 is a synchronous motor. The use of a synchronous motor in this embodiment is beneficial for improving operational stability. Moreover, if the resistance of the synchronous motor suddenly increases during operation, its rotation direction will change; therefore, when the synchronous motor reverses and drives the rotating gear 3 to contact the blocking part 5, the blocking part 5 prevents the rotating gear 3 from continuing to rotate, the synchronous motor experiences increased resistance, and its rotation direction changes to forward rotation.
[0049] When the smoothie machine described in this utility model is in use, the control motor 1 starts working and rotates forward. The motor output shaft 11 rotates clockwise, driving the transmission gear 2 and the stirring assembly 61 to rotate. The transmission gear 2 drives the rotating gear 3 to rotate around its central axis 31, causing the central axis 31 to roll within the arc-shaped groove 41 near the first end of the groove 41. When the central axis 31 abuts against the first end of the arc-shaped groove 41, the central axis 31 continues to rotate within the groove 41, and the motor 1 continues to rotate forward. If the resistance of the stirring assembly 61 suddenly increases during rotation, causing the motor 1 to reverse, then... The motor output shaft 11 rotates counterclockwise and drives the transmission gear 2 to rotate in reverse, thereby causing the central shaft 31 of the rotating gear 3 to roll near the second end of the arc groove 41. The rotating gear 3 moves near the blocking part 5. When the central shaft 31 abuts against the second end of the arc groove 41, the blocking part 5 contacts the rotating gear 3, and the protrusion 52 is engaged in the tooth groove of the rotating gear 3, thereby preventing the rotating gear 3 from continuing to rotate in reverse, and thus causing the motor 1 to stop rotating in reverse. At this time, since the rotating gear 3 is prevented from continuing to rotate in reverse by the blocking part 5, the motor 1 is obstructed more, causing the motor 1 to resume forward rotation.
[0050] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
