Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a reduction motor and a food processor using the reduction motor. Background Art

[0002] Food processors provide convenience for our daily food preparation. In order to meet the processing requirements of different foods, for example, when making soy milk or juice, the requirements of high speed and low torque must be met; when mincing meat and kneading dough, the requirements of low speed and high torque must be met.

[0003] In this regard, food processors in the prior art are generally equipped with a reduction device, which generally adopts an involute planetary gear transmission structure. The overall structure is relatively large in size, but the transmission ratio is relatively small, and the load-bearing capacity is also relatively small.

[0004] For example, the patent with announcement number CN 214707417U discloses a dual-output food processor motor and food processor, which can realize high and low speed output, and can switch between wall breaking, mincing meat and vegetables, shredding, slicing and dough kneading functions by replacing different knives and cups. However, when the motor rotates, the motor output shaft and the reduction output shaft rotate at the same time, which means that when the corresponding reduction output shaft does not need to rotate in actual use, it will also produce rotational motion, thus invisibly increasing the energy consumption of the overall system. In other words, it is impossible to switch the operating state of the reduction output shaft to meet the use requirements of different situations.

[0005] Therefore, with regard to the reduction motor used in the food processor in the prior art, the operating state of the reduction output shaft used therein needs to be further optimized so as to avoid unexpected operation thereof. Utility Model Content

[0006] The first purpose of the utility model is to provide a reduction motor to solve the technical problem of optimizing the running state of the reduction output shaft thereof.

[0007] The first object of the utility model is to provide a food cooking machine to solve the technical problem of reducing operating energy consumption.

[0012] The reduction output assembly includes a reduction transmission structure matched with the one-way clutch and a reduction output shaft connected to the reduction transmission structure; wherein

[0013] When the motor output shaft rotates in a first direction, the one-way clutch is separated from the motor output shaft, and the reduction output assembly is in a non-operating state;

[0014] When the motor output shaft rotates in a second direction opposite to the first direction, the one-way clutch engages with the motor output shaft to rotate synchronously, and the reduction output assembly is adapted to operate to rotate the reduction output shaft at a low speed.

[0015] In an optional implementation of the present invention, the reduction output shaft and the motor output shaft are arranged concentrically and coaxially.

[0016] In an optional implementation of the present invention, the reduction output shaft is provided with a through hole suitable for the motor output shaft to pass through.

[0017] In an optional implementation of the present utility model, the reduction transmission structure includes:

[0018] An eccentric sleeve connected to the one-way clutch so that the eccentric sleeve is adapted to rotate synchronously with the rotation of the one-way clutch;

[0019] A swing arm bearing, which is sleeved on the outside of the eccentric sleeve;

[0020] A cycloid wheel, which is sleeved on the outer side of the swing arm bearing; and

[0021] The pin wheel is arranged outside the cycloid wheel, and the pin wheel is meshed with the cycloid wheel.

[0022] In an optional implementation of the present invention, the reduction output shaft is connected to the cycloid wheel.

[0023] In an optional implementation of the present invention, the reduction output shaft includes a connecting disk connected to the cycloid wheel and a main shaft body connected to the connecting disk.

[0024] In an optional implementation of the present invention, the eccentric sleeve is arranged on the outer side wall of the one-way clutch; and

[0027] The convex key is adapted to fit in with the groove.

[0028] In an optional implementation of the utility model, the keyway structure includes a convex key provided on the outer side wall of the one-way clutch and a groove provided on the inner circumferential wall surface of the eccentric sleeve;

[0029] The convex key is adapted to fit in with the groove.

[0030] The food cooking machine of the utility model is realized as follows:

[0031] A food processor comprises: the reduction motor described above.

[0032] By adopting the above technical scheme, the utility model has the following beneficial effects: the reduction motor of the utility model and the food processor using the reduction motor, firstly, realize the output of different speeds through the cooperation of the motor output shaft and the reduction output shaft, thereby meeting the use requirements of the food processor in different situations. Secondly, by providing a one-way clutch between the motor output shaft and the reduction output assembly, when the motor output shaft rotates in a first direction, the one-way clutch is separated from the motor output shaft, and the reduction output assembly is in a non-operating state; when the motor output shaft rotates in a second direction opposite to the first direction, the one-way clutch is engaged with the motor output shaft and rotates synchronously, and the reduction output assembly is suitable for operation to make the reduction output shaft rotate at a low speed.

DETAILED DESCRIPTION

[0040] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] See also Figures 1 to 4 As shown, this embodiment provides a reduction motor, including: a motor output shaft 1 for outputting power, a one-way clutch 5 arranged on the motor output shaft 1, and a reduction output assembly; wherein the reduction output assembly includes a reduction transmission structure cooperating with the one-way clutch 5 and a reduction output shaft 20 connected to the reduction transmission structure.

[0043] Based on the above structure, when the motor output shaft 1 rotates in a first direction, the one-way clutch 5 is separated from the motor output shaft 1, and the reduction output assembly is in a non-operating state, that is, at this time, the reduction output assembly and the one-way clutch 5 will not operate with the rotation of the motor output shaft 1. However, when the motor output shaft 1 rotates in a second direction opposite to the first direction, the one-way clutch 5 engages with the motor output shaft 1 and rotates synchronously, and the reduction output assembly is suitable for operation to rotate the reduction output shaft 20 at a low speed. It should be noted that the first direction and the second direction here specifically refer to the clockwise and counterclockwise directions during the rotation of the motor output shaft 1, but it is not limited to whether the first direction refers to clockwise or counterclockwise.

[0044] Furthermore, in conjunction with the accompanying drawings, an example of a specific optional implementation is given. The reduction transmission structure adopted in this embodiment adopts a cycloidal pinwheel reduction structure. Compared with the reduction structure using an involute gear, under the same reduction ratio, the cycloidal pinwheel reduction structure is smaller in size, lighter in weight, and has a larger load-bearing capacity than the reduction structure using an involute gear.

[0045] The cycloid pinwheel deceleration structure here can be selected to adopt any mature means in the prior art, and this embodiment does not make an absolute limitation on this. Generally speaking, it includes an eccentric sleeve 6, a cycloid wheel 8, a swing arm bearing 7 and a pinwheel 2 used in conjunction. The inner circle 62 and the outer circle 63 of the eccentric sleeve 6 here are not concentric. In an optional implementation, the eccentricity range of the inner circle 62 and the outer circle 63 is 0.5 to 5 mm. The swing arm bearing 7 can be selected to adopt a deep groove ball bearing.

[0046] The eccentric sleeve 6 is connected to the one-way clutch 5 so that the eccentric sleeve 6 is adapted to rotate synchronously with the rotation of the one-way clutch 5; the swing arm bearing 7 is sleeved on the outside of the eccentric sleeve 6; the cycloid wheel 8 is sleeved on the outside of the swing arm bearing 7; and the pin wheel 2 is arranged on the outside of the cycloid wheel 8, and the pin wheel 2 is meshed with the cycloid wheel 8. Among them, the reduction output shaft 20 is connected to the cycloid wheel 8.

[0047] On the basis of the above structure, it is necessary to further explain that the reduction output shaft 20 used in this embodiment includes a connecting disk 10 connected to the cycloid wheel 8 and a main shaft body 11 connected to the connecting disk 10. The connecting disk 10 here is preferably a circular disk body, and the main shaft body 11 is located at the center of the circular disk body, so that the main shaft body 11 and the circular disk body are in a concentric and coaxial matching structure. The connecting disk 10 here can be optionally connected to the cycloid wheel 8 reliably through, for example, but not limited to, a plurality of pins 9 arranged at intervals along the circumferential direction.

[0048] In this regard, in order to ensure that the reduction output shaft 20 and the motor output shaft 1 do not interfere with each other, they can form the final power output components respectively, and the reduction output shaft 20 is arranged concentrically and coaxially with the motor output shaft 1. In addition, the main shaft body 11 of the reduction output shaft 20 is provided with a through hole suitable for the motor output shaft 1 to pass through.

[0049] In addition, for the one-way reducer, any mature method in the prior art can be optionally adopted, such as but not limited to the one-way clutch 5 disclosed in the announcement number CN202790210U or the one-way clutch 5 disclosed in the publication number CN115750619A. There is no absolute limitation on this embodiment. In order to make the one-way reducer adapt to the eccentric sleeve 6 of the cycloid pinwheel reduction structure of this embodiment, the one-way reducer is generally in the form of a circular ring structure, so that its outer circular wall surface can form a connection with the eccentric sleeve 6.

[0050] More specifically, in order to simplify the connection between the one-way clutch 5 and the eccentric sleeve 6 while maintaining a reliable connection between the two, the eccentric sleeve 6 is sleeved on the outer wall of the one-way clutch 5; and the inner circular wall surface of the eccentric sleeve 6 and the outer wall of the one-way clutch 5 are matched through at least one keyway structure.

[0051] In this regard, this embodiment takes the case where two keyway structures are provided between the one-way clutch 5 and the eccentric sleeve 6 as an example in combination with the accompanying drawings. Regarding the keyway structure here:

[0052] In the first optional implementation, the keyway structure includes a groove 51 provided on the outer wall of the one-way clutch 5 and a convex key 61 provided on the inner wall surface of the eccentric sleeve 6; the convex key 61 is suitable for fitting with the groove 51.

[0053] In the second optional implementation, the keyway structure includes a convex key provided on the outer wall of the one-way clutch 5 and a concave groove provided on the inner wall surface of the eccentric sleeve 6; the convex key is suitable for fitting with the concave groove.

[0054] Based on the above situation, it should be explained that in the third optional implementation, when more than two keyway structures are designed, the keyway structures of the above two different implementations can be used in combination.

[0055] Finally, regarding the reduction motor used in this embodiment, an optional structural layout is given as an example in conjunction with the attached drawings. The front end cover 3 of the reduction motor is provided with a mounting portion 4 for accommodating a one-way clutch 5, an eccentric sleeve 6, a swing arm bearing 7, and a cycloidal gear; and the center hole of the box cover 12 of the reduction motor is installed with a shaft sleeve 13 for cooperating with the main shaft body 11 of the reduction output shaft 20. The box cover 12 is fixed to the front end cover 3 by screws on all sides. The motor output shaft 1 and the reduction output shaft 20 both at least partially penetrate the box cover 12 and extend to the outside of the reduction motor to output power. The motor output shaft 1 and the reduction output shaft 20 have different output speeds, and the specific speed of the reduction output shaft 20 is less than the speed of the motor output shaft 1.

[0056] Embodiment 2:

[0057] See also Figures 1 to 6 As shown, based on the reduction motor of Example 1, this embodiment provides a food processor, including: the reduction motor of Example 1.

[0058] For an example of a specific optional implementation, see Figure 5 As shown, a first coupling 14 is installed on the motor output shaft 1, which can be connected to a cup body 16 and a corresponding cutter 17 of a food processor through an adapted first transmission member 15. At this time, the corresponding motor output shaft 1 can rotate in a first direction, so that the one-way clutch 5 is separated from the motor output shaft 1, and the reduction output component is in a non-operating state, that is, at this time, the reduction output component and the one-way clutch 5 will not operate with the rotation of the motor output shaft 1. This situation can be used in the occasion of high-speed crushing of food materials, such as beating soy milk, sesame and other foods.

[0059] Furthermore, see Figure 6 As shown, the second coupling 18 is installed on the reduction output shaft 20, which can be connected to the two cup bodies 16 and the corresponding cutters 17 of the food processor through the second transmission member 19. At this time, the corresponding motor output shaft 1 rotates in the second direction, so that the one-way clutch 5 and the motor output shaft 1 are engaged and rotate synchronously, and the reduction output assembly is suitable for operation to make the reduction output shaft 20 rotate at a low speed. This situation can be used in the occasion of cutting food at a low speed, such as juicing fruits and vegetables.

[0060] Therefore, for the food processor of this embodiment, the output of different speeds is achieved by the cooperation of the motor output shaft 1 and the reduction output shaft 20, thereby meeting the use requirements of the food processor in different situations. When the reduction output shaft 20 is not needed to operate, it is only necessary to simply control the rotation direction of the motor output shaft 1, which is not only convenient to operate, but also can reduce the energy consumption during the use of the food processor.
