It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5As shown, this utility model embodiment provides a high-torque coffee machine motor, including a motor body 1, a reducer housing 2, a four-head worm gear 3, a worm wheel 4, a first bearing 51, a second bearing 52, a transmission shaft 6, and a locking screw 7. The reducer housing 2 has a first receiving chamber 201 and a second receiving chamber 202 inside, which are connected. The motor body 1 is located on the side of the reducer housing 2, and the motor shaft of the motor body 1 is connected to the four-head worm gear 3. The four-head worm gear 3 is located in the first receiving chamber 201, and the worm wheel 4 is located in the second receiving chamber 202. The worm wheel 4 is connected to the four-head worm gear 6. The worm gear 3 is connected by a rotating meshing mechanism, and the four-headed worm gear 3 is used to drive the worm wheel 4 to rotate. By connecting the motor shaft to the four-headed worm gear 3 and installing the worm gear in the first receiving chamber 201 and the worm wheel 4 in the second receiving chamber 202, when the motor body 1 rotates, the four-headed worm gear 3 can drive the worm wheel 4 to achieve meshing and speed reduction transmission. In addition, compared with the single-headed worm gear, the four-headed worm gear 3 can drive the worm wheel 4 to rotate faster at the same speed, because the worm wheel 4 can engage and move more tooth blocks for each rotation of the worm gear, thereby increasing the transmission speed. This allows the coffee machine motor to achieve high-speed transmission and maintain high torque output, meeting the needs of the coffee machine to operate efficiently and stably under high load conditions.

[0031] The worm gear 4 has an internal toothed hole 40 in the middle. The drive shaft 6 passes through the reducer housing 2. The drive shaft 6 has an external toothed portion 61, a stop portion 62, and an external threaded portion 63 spaced apart along its axial direction. The external toothed portion 61 meshes with the internal toothed hole 40 so that the drive shaft 6 rotates with the rotation of the worm gear 4. The stop portion 62 is located on the side wall of the reducer housing 2. The external threaded portion 63 is used to connect with external transmission components. By meshing the external toothed portion 61 of the drive shaft 6 with the internal toothed hole 40 of the worm gear 4, the worm gear 4 can drive the drive shaft 6 to rotate together when it rotates, thereby realizing power transmission. The stop portion 62 can prevent the drive shaft 6 from sliding axially during rotation. The external threaded portion 63 can easily fix the drive shaft 6 to an external mechanical device to realize power output.

[0032] The first bearing 51 and the second bearing 52 are located at both ends of the reducer housing 2. A washer 70 is provided on the outer wall of the first bearing 51. An internally threaded hole 60 is provided at the end of the drive shaft 6 away from the externally threaded portion 63. The locking screw 7 passes through the washer 70 and connects to the internally threaded hole 60. By providing the first bearing 51 and the second bearing 52 at both ends of the reducer housing 2, the drive shaft 6 is stably supported during rotation, friction is reduced, and the drive shaft 6 can rotate smoothly and efficiently. The locking screw 7 can lock and fix the drive shaft 6, preventing it from shifting.

[0033] like Figure 3 As shown, furthermore, the transmission shaft 6 located on both sides of the external toothed portion 61 is provided with a first journal 601 and a second journal 602. The diameter of the first journal 601 is smaller than the diameter of the second journal 602. The first bearing 51 is sleeved on the first journal 601, and the second bearing 52 is sleeved on the second journal 602. By providing two first journals 601 and second journals 602 with different diameters on the transmission shaft 6, and by respectively sleeved the first bearing 51 and the second bearing 52 on journals of different diameters, the load on the transmission shaft 6 during operation can be better distributed.

[0034] like Figure 2 As shown, the reducer housing 2 further includes a first housing 21 and a second housing 22, which are connected by bolts. This arrangement facilitates the rapid assembly of the coffee machine motor.

[0035] like Figure 3 and Figure 5 As shown, furthermore, the bottom of the four-headed worm gear 3 is provided with a limiting shaft 31, the diameter of which is smaller than the diameter of the four-headed worm gear 3. The bottom of the first receiving chamber 201 is provided with a mounting base 32, and the mounting base 32 is provided with a limiting hole 320 for receiving the limiting shaft 31. By providing a limiting shaft 31 at the bottom of the four-headed worm gear 3 and inserting the limiting shaft 31 into the limiting hole 320 in the mounting base 32, the axial position of the four-headed worm gear 3 can be securely fixed, preventing axial displacement or vibration of the four-headed worm gear 3 during transmission, thereby improving its stability during operation.

[0036] like Figure 3 and Figure 5 As shown, furthermore, the limiting hole 320 is filled with lubricating grease. By filling the limiting hole 320 with lubricating grease, the coefficient of friction between the limiting shaft 31 and the limiting hole 320 can be reduced, wear can be reduced, and the service life of the component can be extended.

[0037] like Figure 1 and Figure 2 As shown, the second journal 602 is further disposed between the external toothed portion 61 and the stop portion 62, and the stop portion 62 abuts against the side end of the second bearing 52 to restrict the second bearing 52 from slipping out of the reducer housing 2.

[0038] Furthermore, the motor body 1 is a DC motor. For coffee machines, a DC motor can provide high torque output at a lower voltage, meeting the high torque requirements of the coffee machine in operations such as grinding coffee beans and tamping powder.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
