Detailed Description

The following description of the preferred embodiments of the present invention will enable one skilled in the art to make and use the present invention as described below, and will more fully understand the innovative features and attendant advantages of the present invention.

The spatula actuating mechanism of the embodiment of the application is used for driving the spatula to move in a kettle body of the automatic cooker, and is used for stirring, stir-frying and the like of materials (raw materials, auxiliary materials and the like for cooking) in the kettle body.

As shown in fig. 1, fig. 1 is an overall structure diagram of the spatula driving mechanism, the utility model provides a spatula driving mechanism, including: the scraper device comprises a clutch 4, a driving part 3 and a driving part 5, wherein one end of the driving part 3 is connected with an output shaft of the driving part 5, and the clutch 4 is provided with an output part 46 used for being connected with the scraper 2; and an input unit 43 connected to the drive unit 3 and capable of being separated from or coupled to the output unit 46.

Referring to fig. 3 and 4, the driving portion 3 is driven by a driving member 5, so that the driving portion 3 can swing around an output shaft of the driving member 5, and thereby drive the spatula 2 connected to the clutch 4 to move, specifically, the driving portion 3 drives the spatula 2 connected to the clutch 4 to enter from the opening 10 of the kettle 1, so that the spatula 2 moves to the bottom of the kettle along the inner wall of the kettle 1, and then drives the spatula 2 to move outwards to the opening of the kettle 1 along the inner wall of the kettle from the bottom of the kettle 1, so as to reciprocate alternately, and the purpose of stir-frying is achieved. When the driving part 3 drives the scraping blade 2 to enter the kettle body 1, the driving part 3 can be disconnected by the clutch 4 to limit the circumferential direction of the scraping blade 2, so that the scraping blade 2 can rotate along with the kettle body 1.

Referring to fig. 1, as an implementation manner, the input portion of the clutch 4 is a sleeve 43, and the clutch 4 specifically includes: the reset device comprises a sleeve 43, a reset piece 42 and an output part 46, wherein one end of the reset piece 42 is limited in the sleeve 43, a first combining part 431 is arranged in the sleeve 43, and a second combining part 48 is arranged on the output part 46; the circumferential spacing between the sleeve 43 and the output 46 is achieved by the engagement of the first and

second coupling portions

431, 48. The other end of the resetting piece 42 is connected with the output part 46 and enables the first combining part 431 to be meshed with the second combining part 48, when the output part 46 is under the action force of the scraper 2, the resetting piece 42 is driven by the action force to cause the second combining part 48 to be separated from the first combining part 431, so that the circumferential limit of the sleeve 43 on the output part 46 disappears, and at the moment, the scraper 2 can rotate along with the kettle 1 under the driving of the kettle 1.

In this embodiment, the engagement and disengagement of the clutch 4, that is, the axial engagement or disengagement of the output portion 46 and the sleeve 43, are realized based on the acting force of the output shaft by the spatula 2, and the clutch process is realized without driving the clutch by the motor, so that the clutch device is more suitable for the stir-frying machine under the environment with more water vapor and more oil smoke, and the cost of the spatula driving mechanism is reduced. If the clutch is driven by the motor to realize the clutch process, the protection level required by the motor is very high, which is not beneficial to the cleaning process.

In this embodiment, the restoring element 42 is an elastic member, and the embodiment takes a spring as an example, but of course, a rubber tube with a corrugated structure may be used instead, or an elastic rubber sleeve or other elastic members may be used instead. The elastic member engages the first engaging portion 431 and the second engaging portion 48 with an elastic force, and presses the elastic member to disengage the first engaging portion 431 and the second engaging portion 48 when the output portion 46 is subjected to an axial force of the spatula 2.

In one embodiment, output 46 is an output shaft that is received within sleeve 43 and extends out of engagement with spatula 2.

As an example, the engagement between the first coupling portion 431 and the second coupling portion 48 is a tooth engagement, but a friction engagement may be used. And the adoption tooth meshing mode can be more stable, especially, under the oil smoke environment, tooth meshing's reliability is better.

In the present embodiment, the first coupling portion 431 and the second coupling portion 48 specifically use straight tooth engagement. As shown in fig. 1, the second combining portion 48 of the output portion 46 is a straight tooth disposed on the circumferential side wall of the shaft, as shown in fig. 2, the inner wall of the sleeve 43 is provided with an annular flange to divide the sleeve 43 into a lower cavity 432 and an upper cavity 433, a guiding structure is disposed on the end surface of the annular flange to provide a first combining portion 431 with the corresponding straight tooth, the upper cavity 433 can provide a disposing space for the elastic member 42, and the lower cavity 433 is used to realize an axial limiting structural arrangement for the output portion 46. The structure of the straight tooth meshing is adopted, the structure is relatively simple, and the processing is easy.

Optionally, a guide structure may be disposed on an end surface of the annular flange along a contour of the first coupling portion, and the guide structure may guide the second coupling portion to start coupling with the first coupling portion, so that the second coupling portion can be smoothly coupled with the first coupling portion; the guide structure may be a chamfered structure provided on an end face profile of the first coupling portion.

As an arrangement of the second coupling portion 48, a shoulder may be provided on the output portion 46, the second coupling portion 48 may be provided on the shoulder, and the second coupling portion 48 may be provided on the shoulder of the output portion 46, whereby the shoulder may be used to limit the output portion 46 in the axial direction.

As an alternative embodiment, the first and

second coupling portions

431 and 48 may also use a bevel or face tooth engagement. The mode that adopts awl tooth meshing or terminal surface tooth meshing can utilize awl tooth structure or terminal surface tooth structure to realize spacing the axial of output shaft, further simplifies the inside structure of sleeve, however, the degree of difficulty of its processing also corresponding improvement.

Taking the embodiment in which the first coupling portion 431 and the second coupling portion 48 are straight teeth as an example, at least one position-limiting sleeve 44 is disposed in the lower cavity 432 to axially limit the output portion 46, so as to ensure that the second coupling portion 48 can be effectively coupled to the first coupling portion 431. In the present embodiment, the number of the stopper sleeves 44 is two, but may be one, three, four, or the like, and is provided according to the axial movement stroke of the output portion 46.

The position-limiting sleeve 44 is fixed to a first end of the sleeve 43, i.e., one end of the lower cavity 432, by a gasket 45. The spacer 45 prevents the position-limiting sleeve 44 from sliding out of the lower cavity 432.

Further, the upper end of the reset member 42 is limited to the second end of the sleeve 43, i.e., one end of the upper cavity 433, by the end cap 41, and the lower end of the reset member 42 abuts against the upper end of the output portion 46 (the end where the second combining portion 48 is located). The end cap 41 can ensure that the reset piece 42 cannot be disengaged from the sleeve 43, and ensure that the reset piece 42 can be abutted against the output part 46.

With continued reference to fig. 1, the first end of the driving portion 3 is fixedly connected to the first end of the sleeve 43 by a screw (or a limiting post, welding, etc.), and the screw can fasten the driving portion 3 and the gasket 45 together; the second end of the driving part 3 may be connected to a driving device, such as a motor. The first end of the spatula 2 is fixedly connected to the lower end of the output portion 46 by fasteners 47, which fasteners 47 may be bolts, screws, or the like.
