Example 1

As shown in fig. 1 to 4, the present embodiment provides a stirring shovel, including a main body 1, a shovel blade 3 and a magnet 2, the main body 1 is provided with a mounting hole 11, the mounting hole 11 includes a first hole 111 and a second hole 112 that are eccentrically arranged and communicate, the shovel blade 3 includes a connecting portion 31 and a stirring portion 32 that are connected, the stirring portion 32 is used for stirring food materials, the connecting portion 31 is arranged in the mounting hole 11 in a penetrating manner, and the magnet 2 is clamped between the main body 1 and the stirring portion 32, so that the main body 1 and the stirring portion 32 can be connected through magnetic attraction of the magnet 2. Specifically, the connecting portion 31 includes a first section 311, the first section 311 being located in the first hole 111 and being rotatable relative to the first hole 111, and the connecting portion 31 further includes a second section 312, the second section 312 being located in the second hole 112 and being rotatable relative to the second hole 112. The first section 311 is connected to the second section 312, and the first hole 111 and the second hole 112 are eccentrically disposed, so that the first section 311 and the second section 312 can be respectively inserted into the first hole 111 and the second hole 112, and the first section 311 and the second section 312 are also eccentrically disposed. Because the first section 311 and the second section 312 are eccentrically arranged and connected, when the first section 311 rotates, the second section 312 can only rotate along the axis of the first section 311, but because the second section 312 and the second hole 112 have a mounting gap along the radial direction of the second hole 112, even if the second section 312 can only rotate along the axis of the first section 311, the second section 312 still has a certain rotation space, so that the rotation of the connecting portion 31 relative to the mounting hole 11 can be realized. When in actual use, the stirring shovel is driven to rotate positively and negatively along with the motor, the magnet 2 is utilized to horizontally rotate, the characteristic that the influence of magnetic attraction is small is utilized, the shovel blade 3 can realize left and right inclination and direction change along with food material resistance, so that the shovel blade 3 can scrape food materials at more positions, the rotating angle of the shovel blade 3 is an inclination angle, and the inclination angle can be used for preventing the food materials from centrifugally moving along with the rotation of the stirring shovel, so that the food materials are prevented from being stirred on the pot wall, the stirring efficiency is improved, and the cooking effect is ensured.

In a specific implementation, the first section 311 is a cylindrical section, the first hole 111 is a circular hole, the first section 311 can rotate 360 ° relative to the first hole 111, the second section 312 is a cylindrical section, the second hole 112 is a circular hole, and the second section 312 can rotate 360 ° relative to the second hole 112. Since the first section 311 and the second section 312 are eccentrically connected, and the second section 312 and the second hole 112 have a mounting gap, the connecting portion 31 can rotate a predetermined angle relative to the mounting hole 11, the predetermined angle can be adjusted according to the size of the mounting gap, and the larger the mounting gap, the larger the predetermined angle. Preferably, as shown in fig. 10, the preset angle is 2α, and the value range of α is 5 ° -85 °. Further preferably, α has a value in the range of 20 ° to 50 °.

Further, to reduce the frictional resistance of the second section 312 in the second hole 112 when the blade 3 rotates relative to the main body 1, a gap exists between the second section 312 and the bottom of the second hole 112 along the axial direction of the mounting hole 11. Preferably, the second section 312 has a length b1 and the second aperture 112 has a depth b2,0.5mm < b2-b1 < 5mm.

Further, to increase the connection stability of the blade 3 and the main body 1 when the blade 3 rotates, the blade 3 is prevented from being separated from the main body 1 due to rotation. The magnet 2 is of an annular structure, the magnet 2 is sleeved on the connecting portion 31, the first magnetic metal ring 12 is arranged at the opening end of the mounting hole 11, the second magnetic metal ring 321 is arranged at the end, facing the mounting hole 11, of the stirring portion 32, and the magnet 2 is magnetically attracted to the first magnetic metal ring 12 and the second magnetic metal ring 321. Because the magnet 2, the first magnetic metal ring 12 and the second magnetic metal ring 321 are all annular, the magnetic attraction areas of the magnet 2, the first magnetic metal ring 12 and the second magnetic metal ring 321 are larger, and the magnetic attraction distribution of all positions is more uniform, so that the shovel blade 3 is ensured to be attracted magnetically everywhere, and the shovel blade 3 can be prevented from being separated from the main body 1.

Example two

As shown in fig. 5 to 10, the present embodiment provides a stirring blade, which is different from the stirring blade of the first embodiment in that:

the first section 311 includes a penetrating section 3112 and a limiting section 3111, and the penetrating section 3112 is connected to one end of the limiting section 3111, which is away from the second section 312, the first hole 111 includes a penetrating hole 1112 and a limiting hole 1111, the penetrating hole 1112 is communicated to one end of the limiting hole 1111, which is away from the second hole 112, when the first section 311 is penetrated into the first hole 111, the penetrating section 3112 is located in the penetrating hole 1112, and the limiting section 3111 is located in the limiting hole 1111. The limiting section 3111 is used for further preventing the connection portion 31 from being separated from the mounting hole 11 when the shovel blade 3 rotates relative to the main body 1, that is, the limiting section 3111 is located in the limiting hole 1111, and the limiting section 3111 needs to pass through the through hole 1112 in a preset manner. When the limiting segment 3111 passes through the through hole 1112 and is located in the limiting hole 1111, if the second segment 312 is also located in the limiting hole 1111, the first segment 311 can still rotate relative to the first hole 111, the rotation angle of the first segment 311 relative to the first hole 111 is β, and as the second segment 312 is inserted into the second hole 112, the rotation of the first segment 311 relative to the first hole 111 is limited to rotate only by the preset angle 2α, β > 2α. Because the first section 311 and the second section 312 are eccentrically disposed, when the first section 311 is inserted into the first hole 111, the first section 311 needs to be rotated to find a position concentric with the second section 312 and the second hole 112, i.e. needs to be rotated until the second section 312 is aligned with the second hole 112, so as to facilitate the second section 312 to be inserted into the second hole 112.

Alternatively, as shown in fig. 6 and 7, the inner wall of the through hole 1112 is provided with an internal thread, and the outer wall of the limiting section 3111 is provided with an external thread, and the internal thread is engaged with the external thread. That is, in practice, it is necessary to rotate the connection portion 31 so that the stopper segment 3111 is threadedly engaged with the through-hole 1112 during rotation, thereby passing through the through-hole 1112. When the limiting segment 3111 has been moved into the limiting aperture 1111, the external thread of the limiting segment 3111 and the internal thread of the through hole 1112 are blocked by each other even if the blade 3 rotates relative to the main body 1, so as to prevent the connection portion 31 from being disengaged from the mounting hole 11.

Preferably, as shown in fig. 8 and 9, in order to reduce the friction resistance of the first section 311 in the first hole 111 when the blade 3 rotates relative to the main body 1, the second section 312 extends into the second hole 112 along the axial direction of the mounting hole 11 by a depth b1, and the penetrating section 3112 extends into the limiting hole 1111 by a depth a, b1 < a. In particular, the second section 312 and the limiting section 3111 can be located in the limiting hole 1111 at the same time to ensure that the first section 311 and the first hole 111 have a relative rotation angle β, and then the connecting portion 31 is rotated to be coaxial with the second section 312 and the second hole 112, so that the connecting portion 31 can be moved along the axial direction of the mounting hole 11, so that the second section 312 is inserted into the second hole 112. Because the limiting section 3111 is connected to the penetrating section 3112, when the second section 312 moves into the second hole 112, the penetrating section 3112 necessarily moves partially into the limiting hole 1111, and the depth b1 of the second section 312 extending into the second hole 112 is at most consistent with the depth a of the penetrating section 3112 extending into the limiting hole 1111. In order to reduce the frictional resistance of the first section 311 against the bottom of the first hole 111, a gap L exists between the stopper section 3111 and the bottom of the first hole 111. It is known that, along the axial direction of the mounting hole 11, the sum of L and b1 is the length of the second section 312, and the sum of the length of the second section 312 and the length of the penetrating section 3112 is equal to the sum of the length of the penetrating section 3112 and the depth a of the penetrating section 3112 extending into the limiting hole 1111, if L > 0, i.e. a-b1 > 0.

Further, as shown in fig. 9, the mounting hole 11 further includes a third hole 113, the connecting portion 31 further includes a third section 313, the third section 313 is concentrically connected to an end of the first section 311 facing away from the second section 312, and the third section 313 is disposed in the third hole 113 in a penetrating manner and is capable of rotating relative to the third hole 113. And along the radial direction of the mounting hole 11, the cross-sectional area of the third section 313 is larger than that of the first section 311, so that the third section 313 can be used as a pivot point for rotating the connecting portion 31 by using the abutting of the third section 313 and the third hole 113, compared with the abutting of the penetrating section 3112 and the internal thread, the stress is more uniform, and the abrasion of the internal thread on the penetrating section 3112 can be avoided. In addition, the connecting portion 31 is connected with the stirring portion 32 through the third section 313, so that the magnet 2 needs to be penetrated from one end of the connecting portion 31 away from the stirring portion 32, and passes through the second section 312 and the first section 311, and finally moves to the third section 313, and the cross-sectional area of the second section 312 is smaller than that of the third section 313, so that the magnet 2 is more convenient to install.

Preferably, as shown in fig. 9, in order to reduce friction resistance between the third section 313 and the bottom of the third hole 113 when the blade 3 rotates relative to the main body 1, a first step surface 1131 is formed at a position where the third hole 113 communicates with the first hole 111 along the axial direction of the mounting hole 11, a second step surface 3131 is formed at a position where the third section 313 and the first section 311 are connected, and a distance between the first step surface 1131 and the second step surface 3131 is c, where 0.5mm < c < 5mm.

In addition, the other structures of the stirring shovel provided in this embodiment are the same as those of the stirring shovel in the first embodiment, and are not described here again.

Example III

As shown in fig. 11 to 13, the present embodiment provides a stirring blade, which is different from the stirring blade in the second embodiment in that:

the spacing segment 3111 is of non-cylindrical configuration, and the spacing segment 3111 is disposed within the bore 1112, with the second segment 312 being non-coaxial with the second bore 112. That is, when the limiting segment 3111 passes through the through hole 1112 in a preset manner and is located in the limiting hole 1111 with the second segment 312, the first segment 311 needs to be rotated so that the second segment 312 is coaxial with the second hole 112, and thus the subsequent second segment 312 is inserted into the second hole 112, but when the first segment 311 rotates to deviate from its original position, the first segment 311 cannot be separated from the through hole 1112 any more.

In this embodiment, the limiting section 3111 has an elliptical structure, the through hole 1112 is an elliptical hole adapted to the through hole, the limiting hole 1111 is a circular hole, and the first section 311 and the first hole 111 have a relative rotation angle β. When the elliptical structure passes through the elliptical hole in a preset posture and rotates a certain angle in the limiting hole 1111, the elliptical structure can not be separated from the elliptical hole any more.

In addition, the other structures of the stirring shovel provided in the present embodiment are the same as those of the stirring shovel in the second embodiment, and are not described herein.
