Description

Technical Field

[0001] This application relates to the technical field of coffee machine accessories, and in particular to a motor structure for a coffee machine. Background Technology

[0002] As people's demands for coffee quality and production efficiency continue to increase, the performance and stability of coffee machines are becoming increasingly important. Among them, the motor structure, as the core power component of the coffee machine, directly affects the overall working effect of the coffee machine.

[0003] Regarding the aforementioned technologies, it has been found that existing coffee machine motor structures typically employ a relatively simple cylindrical housing design. This design lacks flexibility during installation and makes it difficult to properly avoid interference with other components due to the complex internal spatial structure of the coffee machine. This can affect the overall layout of the coffee machine and the effective utilization of its internal space.

[0004] In terms of transmission, traditional motor structures mostly adopt single-stage transmission or simple multi-stage transmission methods. This type of transmission method has certain limitations in the adjustment of speed and torque. Single-stage transmission cannot simultaneously meet the requirements of reducing speed and increasing torque, while simple multi-stage transmission structures are not stable enough and are prone to problems such as decreased transmission accuracy and increased noise. Utility Model Content

[0005] In order to achieve reasonable space avoidance during motor installation, this application provides a motor structure for a coffee machine.

[0006] The technical solution for a coffee machine motor structure provided in this application is as follows:

[0007] A motor structure for a coffee machine includes an arc-shaped housing. The arc-shaped housing includes a main frame and a mating cover. The mating cover is snap-fitted onto one side of the main frame and is fixedly connected to the main frame. An output gear is also installed in the arc-shaped housing and is rotatably connected to the arc-shaped housing. A transmission gear set for driving the output gear is installed in the main frame and is rotatably connected to the main frame. A drive mechanism for driving the transmission gear set is installed on the outer surface of the mating cover and is fixedly connected to the mating cover.

[0008] By adopting the above technical solution, the arc-shaped housing allows for proper installation of the coffee bean cutter inside the coffee machine. The arc shape provides reasonable clearance, and the design of the arc-shaped housing, combining a main frame and a matching cover, facilitates the installation and maintenance of internal components. Furthermore, the output gear and transmission gear set work together to achieve stable installation and transmission within the arc-shaped housing. A drive mechanism that drives the transmission gear set is fixedly mounted on the outer surface of the matching cover. During operation, the drive mechanism rotates the transmission gear set, which in turn drives the output gear to rotate synchronously. The output gear then drives the high-speed rotation of the coffee bean cutter shaft. The rational layout of the output gear, transmission gear set, and drive mechanism ensures more stable and efficient power transmission, providing reliable power support for the coffee machine.

[0009] Optionally, the main frame includes a back plate, a top arc plate, a bottom arc plate, and an outer side plate. The top arc plate and the bottom arc plate are installed on the upper and lower sides of the front end face of the back plate. The upper end of the outer side plate is connected to one side of the top arc plate, and the lower end of the outer side plate is connected to one side of the bottom arc plate. The back plate, the top arc plate, the bottom arc plate, and the outer side plate are integrally formed. The bottom arc plate is provided with a mating groove for the output gear to extend out.

[0010] By adopting the above technical solution, the main frame uses an integrally molded back plate, top arc plate, bottom arc plate, and outer side plate structure, which enhances the overall strength and stability of the main frame. The structure composed of the back plate, top arc plate, bottom arc plate, and outer side plate has an open front end and upper end, which facilitates connection and use with the mating cover. The mating groove opened on the bottom arc plate facilitates the extension of the output gear, ensuring the effective output of power from the output gear and realizing the stable rotation of the coffee machine cutter shaft.

[0011] Optionally, the mating cover includes a front cover plate and a connecting top plate, wherein the connecting top plate is disposed at the head of the front cover plate and is integrally formed with the front cover plate.

[0012] By adopting the above technical solution, the front cover plate and the connecting top plate of the housing cover are integrally formed, resulting in a simple structure that is easy to manufacture and install. When the housing cover is installed on the main housing frame, the front end of the main housing frame can be shielded and protected by the front cover plate, while the upper end of the main housing frame can be sealed and shielded by the connecting top plate. At the same time, the setting of the connecting top plate provides stable support for the installation of the drive mechanism.

[0013] Optionally, the transmission gear set includes a first double gear, a second double gear, a third double gear, and a fourth double gear, wherein the first double gear, the second double gear, the third double gear, and the fourth double gear mesh with each other in sequence, and the first double gear, the second double gear, the third double gear, and the fourth double gear are all rotatably mounted in the main housing.

[0014] By adopting the above technical solution, the transmission gear set is designed with a structure in which a first double gear, a second double gear, a third double gear, and a fourth double gear mesh together. In use, the first double gear drives the second double gear to rotate, the second double gear drives the third double gear to rotate, the third double gear drives the fourth double gear to rotate, and finally the fourth double gear drives the output gear to rotate. By using multiple double gears meshing with each other in sequence, multi-stage transmission can be achieved, effectively reducing the speed, increasing the torque, and improving the transmission efficiency and stability. At the same time, the structure of multiple sets of double gears meshing together facilitates stable transmission and also allows for arc-shaped layout according to the structure of the arc-shaped housing, increasing the flexibility of installation.

[0015] Optionally, the first dual gear includes a first helical gear and a first spur gear, wherein the first spur gear is coaxially mounted on one side of the first helical gear, and the first spur gear is integrally formed with the first helical gear.

[0016] By adopting the above technical solution, the first helical gear and the first spur gear of the first double gear are integrally formed, which ensures the coaxiality and transmission accuracy between the two, making the power transmission more stable. In use, the first helical gear is used to connect with the drive mechanism, and then the first spur gear drives the second double gear to rotate.

[0017] Optionally, the drive mechanism includes a motor and a second helical gear meshing with the first helical gear. The motor is vertically fixed to the upper end face of the connecting top plate, and the output shaft of the motor extends through the connecting top plate into the arc-shaped housing. The second helical gear is fixedly mounted on the output shaft of the motor.

[0018] By adopting the above technical solution, the drive mechanism uses a motor to drive the second helical gear to mesh with the first helical gear, thereby achieving power transmission. The motor is vertically mounted on the connecting top plate, resulting in a compact structure that saves space. Furthermore, the motor is mounted on the outside of the arc-shaped housing, facilitating heat dissipation and maintenance.

[0019] Optionally, the second, third, and fourth double gears each include a second large gear and a second small gear, with the second small gear coaxially disposed on one side of the second large gear, and the second small gear being integrally formed with the second large gear.

[0020] By adopting the above technical solution, the second, third, and fourth double gears all adopt a structure in which the second large gear and the second small gear are integrally formed, which can achieve different transmission ratios, further optimize the transmission effect, and meet the power requirements of different working parts of the coffee machine. In use, the second large gear of the second double gear meshes with the first straight gear of the first double gear, the second small gear of the second double gear meshes with the second large gear of the third double gear, the second small gear of the third double gear meshes with the second large gear of the fourth double gear, and the second small gear of the fourth double gear meshes with the output gear, thereby realizing synchronous transmission operation from the first double gear to the output gear.

[0021] Optionally, the inner side of the front cover plate is provided with a positioning shaft for mounting the first double gear, the second double gear, the third double gear and the fourth double gear. One end of the positioning shaft is integrally formed with the front cover plate, and the inner side of the back plate is provided with a reinforcing sleeve that cooperates with the other end of the positioning shaft.

[0022] By adopting the above technical solution, the positioning shaft on the inner side of the front cover plate and the reinforcing sleeve on the inner side of the back plate cooperate to provide stable installation and support for the transmission gear set, reduce shaking and noise during gear transmission, and improve the stability of the entire motor structure.

[0023] In summary, this application includes at least one of the following beneficial technical effects: This application achieves stable transmission by using an arc-shaped housing to allow for arc-shaped avoidance during installation in a coffee machine, and by installing multiple sets of gears within the arc-shaped housing. Furthermore, by designing the arc-shaped housing as a structure where the main frame and the mating cover cooperate, it ensures convenient and flexible disassembly and assembly, as well as flexible installation of the transmission gear set. Moreover, by designing the transmission gear set as a structure where a first double gear, a second double gear, a third double gear, and a fourth double gear cooperate, and by using multiple double gears meshing sequentially, multi-stage transmission can be achieved, effectively reducing speed and increasing torque. Simultaneously, the structure of multiple sets of double gears cooperating facilitates stable transmission and also allows for arc-shaped installation according to the arc-shaped housing structure, increasing installation flexibility.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a motor structure for a coffee machine. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, a motor 31 for a coffee machine includes an arc-shaped housing 1. The arc-shaped housing 1 includes a main frame 11 and a mating cover 12. The mating cover 12 is snapped onto one side of the main frame 11 and is fixedly connected to the main frame 11. An output gear 4 is also installed in the arc-shaped housing 1 and is rotatably connected to the arc-shaped housing 1. A transmission gear set 2 for driving the output gear 4 is installed in the main frame 11 and is rotatably connected to the main frame 11. A drive mechanism 3 for driving the transmission gear set 2 is installed on the outer surface of the mating cover 12 and is fixedly connected to the mating cover 12. The arc-shaped housing 1 facilitates the installation of the motor inside the coffee machine, allowing for reasonable clearance. The design of the arc-shaped housing 1 as a combination of the main frame 11 and the mating cover 12 facilitates the installation and maintenance of internal components. Furthermore, the stable installation and transmission within the arc-shaped housing 1 are achieved through the cooperation of the output gear 4 and the transmission gear set 2. By fixing the drive mechanism 3, which drives the transmission gear set 2 to rotate, on the outer surface of the housing cover 12, the transmission gear set 2 can be rotated by the drive mechanism 3 during operation. Then, the output gear 4 is rotated synchronously by the transmission gear set 2, which in turn drives the coffee bean cutting shaft to rotate at high speed. The reasonable layout of the output gear 4, the transmission gear set 2, and the drive mechanism 3 makes the power transmission more stable and efficient, providing reliable power support for the coffee machine.

[0032] Reference Figure 3 , Figure 4 and Figure 5 As shown, the main frame 11 includes a back plate 111, a top arc plate 112, a bottom arc plate 113, and an outer plate 114. The top arc plate 112 and the bottom arc plate 113 are installed on the upper and lower sides of the front end face of the back plate 111. The upper end of the outer plate 114 is connected to one side of the top arc plate 112, and the lower end of the outer plate 114 is connected to one side of the bottom arc plate 113. The back plate 111, the top arc plate 112, the bottom arc plate 113, and the outer plate 114 are integrally formed. The bottom arc plate 113 has a mating groove 110 for the output gear 4 to extend out. The main frame 11 adopts an integrally formed back plate 111, top arc plate 112, bottom arc plate 113, and outer plate 114 structure, which enhances the overall strength and stability of the main frame 11. The structure consisting of the back plate 111, top arc plate 112, bottom arc plate 113, and outer side plate 114 has an open front end and top end, facilitating connection with the mating cover 12. The mating groove 110 on the bottom arc plate 113 facilitates the extension of the output gear 4, ensuring effective power output of the output gear 4 and enabling stable rotation of the coffee machine's cutter shaft. The mating cover 12 includes a front cover plate 121 and a connecting top plate 122. The connecting top plate 122 is located at the head of the front cover plate 121 and is integrally formed with the front cover plate 121. The front cover plate 121 and the connecting top plate 122 of the housing cover 12 are integrally formed, which has a simple structure and is easy to manufacture and install. When the housing cover 12 is installed on the main housing frame 11, the front end of the main housing frame 11 can be shielded and protected by the front cover plate 121, while the upper end of the main housing frame 11 can be sealed and shielded by the connecting top plate 122. At the same time, the setting of the connecting top plate 122 provides stable support for the installation of the drive mechanism 3.

[0033] Reference Figure 3 and Figure 4As shown, the transmission gear set 2 includes a first double gear 21, a second double gear 22, a third double gear 23, and a fourth double gear 24. These gears mesh sequentially and are rotatably mounted within the main housing 11. By designing the transmission gear set 2 with the first double gear 21, second double gear 22, third double gear 23, and fourth double gear 24 engaging, in operation, the first double gear 21 drives the second double gear 22 to rotate, the second double gear 22 drives the third double gear 23 to rotate, the third double gear 23 drives the fourth double gear 24 to rotate, and finally, the fourth double gear 24 drives the output gear 4 to rotate. This sequential meshing of multiple double gears enables multi-stage transmission, effectively reducing speed, increasing torque, and improving transmission efficiency and stability. Furthermore, the structure of multiple sets of cooperating double gears facilitates stable transmission and allows for flexible installation based on the arc-shaped housing 1. The first double gear 21 includes a first helical gear 211 and a first spur gear 212. The first spur gear 212 is coaxially mounted on one side of the first helical gear 211, and the first spur gear 212 is integrally formed with the first helical gear 211. The integral formation of the first helical gear 211 and the first spur gear 212 of the first double gear 21 ensures the coaxiality and transmission accuracy between them, making the power transmission smoother. In use, the first helical gear 211 is used to connect with the drive mechanism 3, and then the first spur gear 212 drives the second double gear 22 to rotate. The second double gear 22, the third double gear 23, and the fourth double gear 24 each include a second large gear 221 and a second small gear 222. The second small gear 222 is coaxially located on one side of the second large gear 221, and the second small gear 222 is integrally formed with the second large gear 221. The second double gear 22, the third double gear 23, and the fourth double gear 24 all adopt a structure in which the second large gear 221 and the second small gear 222 are integrally formed, which can realize different transmission ratios, further optimize the transmission effect, and meet the power requirements of different working parts of the coffee machine. In use, the second large gear 221 of the second double gear 22 meshes with the first straight gear 212 of the first double gear 21, the second small gear 222 of the second double gear 22 meshes with the second large gear 221 of the third double gear 23, the second small gear 222 of the third double gear 23 meshes with the second large gear 221 of the fourth double gear 24, and the second small gear 222 of the fourth double gear 24 meshes with the output gear 4, thereby realizing synchronous transmission operation from the first double gear 21 to the output gear 4.

[0034] Reference Figure 3As shown, the drive mechanism 3 includes a motor 31 and a second helical gear 32 that meshes with the first helical gear 211. The motor 31 is vertically fixed to the upper surface of the connecting top plate 122, and the output shaft of the motor 31 extends through the connecting top plate 122 into the arc-shaped housing 1. The second helical gear 32 is fixedly mounted on the output shaft of the motor 31. The drive mechanism 3 transmits power by having the second helical gear 32 mesh with the first helical gear 211 through the motor 31. The motor 31 is vertically mounted on the connecting top plate 122, resulting in a compact structure that saves space. Furthermore, the motor 31 is mounted outside the arc-shaped housing 1, facilitating heat dissipation and maintenance.

[0035] Reference Figure 5 As shown, a positioning shaft 123 is provided on the inner side of the front cover plate 121 for mounting the first double gear 21, the second double gear 22, the third double gear 23, and the fourth double gear 24. One end of the positioning shaft 123 is integrally formed with the front cover plate 121, and a reinforcing sleeve 115 is provided on the inner side of the back plate 111 to cooperate with the other end of the positioning shaft 123. The positioning shaft 123 on the inner side of the front cover plate 121 and the reinforcing sleeve 115 on the inner side of the back plate 111 cooperate to provide stable installation and support for the transmission gear set 2, reduce shaking and noise during gear transmission, and improve the stability of the entire motor 31 structure.

[0036] The implementation principle of a motor structure for a coffee machine according to an embodiment of this application is as follows: In actual use, after the motor 31 is started, the output shaft of the motor 31 drives the second helical gear 32 to rotate. The second helical gear 32 meshes with the first helical gear 211, thereby driving the first double gear 21 to rotate. The first spur gear 212 of the first double gear 21 meshes with the second large gear 221 of the second double gear 22, sequentially driving the second double gear 22, the third double gear 23, and the fourth double gear 24 to rotate. Finally, the fourth double gear 24 drives the output gear 4 to rotate, transmitting power to other working parts of the coffee machine to realize the various functions of the coffee machine.
