It should be understood that since the first rotating body 10 and the second rotating body 20 are engaged with each other and rotated in synchronization, the axial directions thereof are the same, both being in the direction of the rotation axis L as shown in fig. 3.

In the stirring assembly 1 provided by the embodiment of the present invention, the transmission shaft and the stirring head which are matched with each other are respectively defined as a first rotating body 10 and a second rotating body 20, the limiting groove 12 is disposed on the side of the shaft body 11 of the first rotating body 10, and the elastic limiting piece 22 is disposed at the second rotating body 20, so that the elastic limiting piece 22 can be clamped into the limiting groove 12 of the first rotating body 10 by using the self elastic force of the elastic limiting piece 22, and the first rotating body 10 is prevented from moving axially relative to the elastic limiting piece 22, and the elastic limiting piece 22 and the body 21 of the second rotating body 20 are relatively fixed in the axial direction, so that the axial fixation of the first rotating body 10 and the second rotating body 20 can be realized, and the stirring head is effectively prevented from falling off in the using process.

When the mixing head is disassembled, because the limit groove 12 is arranged at the side of the shaft body 11, when the mixing head bears an external force far away from the transmission shaft, the elastic limit part 22 can be mutually extruded with part of the inner wall of the limit groove 12, the extrusion force from the limit groove 12 borne by the elastic limit part 22 can generate a component force along the opening direction of the limit groove 12, if the component force exceeds the elastic force of the elastic limit part 22, the elastic limit part 22 can be deformed, moves towards the direction far away from the limit groove 12 and finally breaks away from the limit groove 12, the axial limit is released, the mixing head and the transmission shaft can be axially separated, and the mixing head can be conveniently disassembled.

Optionally, the retaining groove 12 is an annular groove. Since the first rotating body 10 and the second rotating body 20 need to be circumferentially limited, the positions of the limiting groove 12 and the elastic limiting member 22 should be adapted to the circumferential limitation and cannot be freely set. By designing the limiting groove 12 as an annular groove, it is not necessary to determine the circumferential position of the limiting groove 12 in advance when the limiting groove 12 is machined, so that the positioning workload can be reduced, and the production efficiency can be improved.

In some embodiments, as shown in fig. 3 to 5, the body 21 includes a first body 211 and a second body 212, the second body 212 is embedded in the first body 211 and connected to the first body 211, the second body 212 and the first body 211 enclose to form an accommodating interlayer, and a side wall of the second body 212 is provided with a limiting opening 213 corresponding to the limiting groove 12; the elastic limiting member 22 is located in the accommodating interlayer, the elastic limiting member 22 includes a limiting section 221, and the limiting section 221 extends into the limiting opening 213 and protrudes from the inner sidewall of the assembling cavity.

In addition, the side wall of the second body 212 is provided with the limiting opening 213, and the elastic limiting member 22 is provided with the limiting section 221 capable of extending into the limiting opening 213 and the limiting groove 12, so that the limiting function can be satisfied, and the reliable connection of the first rotating body 10 and the second rotating body 20 can be realized. Specifically, the aforementioned assembly cavity is configured on the inner side of the second body 212, the outer side of the second body 212 and the first body 211 enclose an accommodating interlayer, and the limiting opening 213 on the sidewall of the second body 212 can communicate with the accommodating interlayer and the assembly cavity.

As an example, as shown in fig. 3, when the transmission shaft is the first rotating body 10 and the agitating head is the second rotating body 20, the first body 211 includes agitating blades 2111 and an agitating cover 2112; as shown in fig. 10, the first rotating body 10 is a stirring head, the transmission shaft is a second rotating body 20, the first body 211 forms a main shaft of the transmission shaft and can be directly connected with a power device, and the first rotating body 10 further comprises a stirring blade 14 connected with the shaft body 11.

In some embodiments, the elastic limiting element 22 extends around the outer edge of the second body 212, and the elastic limiting element 22 is in a curved ring shape or a curved ring shape with a gap, as shown in fig. 6, the limiting segment 221 is a curved segment recessed toward the center of the elastic limiting element 22.

In these embodiments, the elastic limiting member 22 forms an integral elastic limiting structure surrounding the second body 212, and the integral structure itself is relatively stable, and the second body 212 can provide support in the circumferential direction, so that the elastic limiting member 22 is ensured to be stable in overall structure and not easy to be dislocated, thereby ensuring the reliability of the elastic limiting member 22 in the working process. Meanwhile, the integrated simple structure can reduce the number of parts and is beneficial to improving the assembly efficiency in the production process. In addition, the elastic limiting member 22 is a curved ring shape, and can be adapted to the shape of the second body 212, which is helpful to strengthen the circumferential support of the second body 212 on the elastic limiting member 22, and ensure the operational reliability of the elastic limiting member 22. Correspondingly, spacing section 221 designs for the bending section of inside salient, compares in the design of straight section, can enough increase with spacing mouthful 213 area of contact, promotes spacing effect, prevents that the stirring head from droing in the use, can increase again with the area of contact of spacing groove 12 to elasticity is to the impact of spacing groove 12 when reducing the assembly, can reduce the impaired risk of spacing groove 12, helps prolonging the life of product. In addition, the elastic limiting member 22 may be a complete ring shape connected end to ensure the structural strength, or may be a non-closed ring shape with a gap as shown in fig. 6, which can improve the elasticity of the elastic limiting member 22, so that the elastic limiting member is easy to elastically deform and is convenient for quick assembly and disassembly.

Specifically, as shown in fig. 7 and 8, in the uninstalled state, the position-limiting section 221 will partially penetrate through the position-limiting opening 213 of the body 21 to reach the assembly cavity, so as to ensure that in the installed state, the position-limiting section 221 can be inserted into the position-limiting groove 12 under the action of the elastic force.

In some embodiments, as shown in fig. 3, 4 and 8, the second body 212 includes a fitting portion 2121 and a connecting portion 2122 connected in the axial direction of the second rotating body 20, the fitting portion 2121 is located between the inner bottom wall of the first body 211 and the connecting portion 2122, the outer side wall of the connecting portion 2122 is connected to the first body 211, the outer side wall of the second body 212 forms a stepped surface at the connection of the fitting portion 2121 and the connecting portion 2122, and the limiting opening 213 is located at the fitting portion 2121 and adjacent to the connecting portion 2122.

In these embodiments, the second body 212 is designed as a stepped structure of the fitting portion 2121 and the connecting portion 2122. Here, the fitting portion 2121 is closer to the inner bottom wall of the first body 211 than the connecting portion 2122 (the fitting portion 2121 may or may not be in contact with the inner bottom wall of the first body 211 as shown in fig. 8), and a positional relationship is formed such that the fitting portion 2121 is located inward and the connecting portion 2122 is located outward. The outer side wall of the connecting portion 2122 located relatively to the outside is connected to the first body 211, so that the opening for accommodating the interlayer can be sealed, and the exposure of the internal structure can be reduced. Through setting up spacing mouth 213 in cooperation portion 2121 to specifically be located the step, can utilize the platform face of connecting portion 2122 to provide the support for elasticity locating part 22, further ensured the relatively fixed of elasticity locating part 22 with body 21, and usable stair structure conveniently fixes a position the mounted position of elasticity locating part 22 in the production assembly, help promoting assembly efficiency.

Because the gap between the elastic limiting part 22 and the limiting port 213 is extremely small, liquid forms a natural barrier at the gap by utilizing surface tension, the risk that the liquid enters the accommodating interlayer through the limiting port 213 can be reduced, and the internal cleanness can be basically guaranteed.

Regarding the fixation of the first body 211 and the second body 212, in other embodiments, the connection portion 2122 is threadedly coupled to the first body 211.

In these embodiments, the connecting portion 2122 is screwed to the first body 211, so that the first body 211 and the second body 212 can be detachably connected to each other, and can be separated from each other if necessary, thereby improving the flexibility of use. As an example, the second body 212 may be held by a tool capable of holding the second body 212 while the first body 211 is fixed, or a tool adapted to the fitting cavity may be extended into the fitting cavity to be circumferentially spaced from the second body 212, and then the tool may be rotated to rotationally separate the first body 211 and the second body 212. Of course, other possible ways of separating the two may be used, and the utility model is not limited.

With respect to the fixation of the first body 211 and the second body 212, in other embodiments, as shown in fig. 9, the connecting portion 2122 is screwed with the first body 211; the second body 212 further includes a holding portion 2123, the holding portion 2123 is located at an end of the connecting portion 2122 away from the mating portion 2121, and the holding portion 2123 protrudes from the first body 211.

In these embodiments, the connecting portion 2122 is screwed to the first body 211, so that the first body 211 and the second body 212 can be assembled and disassembled in daily use, and the cleaning requirements of some users with high cleaning requirements can be met. In addition, by disposing the grip portion 2123 protruding from the first body 211 for the second body 212, an acting point can be provided for the user to detach the first body 211 and the second body 212, thereby ensuring smooth detachment.

Optionally, the grip 2123 is a non-slip material grip 2123. In these embodiments, by manufacturing the grip portion 2123 with an anti-slip material, such as food-grade silicone rubber, natural rubber, or butyl rubber, the anti-slip performance of the grip portion 2123 can be improved, so that the first body 211 and the second body 212 can be easily detached.

Optionally, the surface of the grip portion 2123 is provided with a layer of anti-slip material. In these embodiments, since the anti-slip material is often soft, it is not convenient for the user to exert force, and by only providing the anti-slip material layer on the surface of the grip portion 2123, not only the anti-slip effect can be achieved, but also the material selection of the grip portion 2123 itself can be more free, and the material with higher strength can be selected, so as to exert force to the user. For example, the grip portion 2123, the matching portion 2121, and the connecting portion 2122 may be made of the same material, and the three portions are integrally formed, which is helpful to ensure the strength of the connection structure of the three portions and prolong the service life of the product.

In some embodiments, as shown in fig. 3, the first rotating body 10 further includes a connecting plate 13, the connecting plate 13 extends from a side wall of the shaft body 11 toward a direction away from the rotation axis L of the shaft body 11 and bends to extend along an axial direction of the shaft body 11, and the limiting groove 12 is provided on the connecting plate 13.

In these embodiments, in the case where the main structure of the first rotating body 10 is thin, for example, the first rotating body 10 is a transmission shaft, by providing the connecting disc 13 for the first rotating body 10, the corresponding portion of the first rotating body 10 can be thickened, and the stopper groove 12 is provided on the connecting disc 13, specifically, on the portion of the connecting disc 13 extending in the axial direction of the shaft body 11, which helps to accommodate the elastic stopper 22 having a large radial dimension (which determines the radial direction based on the rotation axis L). In the case where the elastic limiting member 22 is an integral structure enclosed in the accommodating interlayer of the body 21, a larger radial dimension tends to mean a larger elasticity, thus facilitating quick assembly and disassembly.

In some embodiments, as shown in fig. 4 and 11, a guide surface 121 is configured in the position-limiting groove 12 to guide the elastic limiting member 22 to be inserted into or separated from the position-limiting groove 12.

In these embodiments, as mentioned above, when the mixing head is disassembled, a part of the inner wall of the limiting groove 12 and the elastic limiting member 22 will be pressed against each other, and by forming the guiding surface 121 at the corresponding position of the limiting groove 12, the component force along the opening direction of the limiting groove 12 can be increased, and the elastic limiting member 22 is guided to move outwards, so that the mixing head can be disassembled conveniently. Specifically, the guide surface 121 is a partial inner wall surface of the stopper groove 12 in the direction of installation of the second rotating body 20. As shown in fig. 3 and 4, when the transmission shaft is the first rotating body 10 and the stirring head is the second rotating body 20, the first rotating body 10 is at the lower part, the second rotating body 20 is at the upper part, and the guide surface 121 is the upper inner wall surface of the limit groove; as shown in fig. 10 and 11, when the mixing head is the first rotating body 10 and the transmission shaft is the second rotating body 20, the first rotating body 10 is located upward, the second rotating body 20 is located downward, and the guide surface 121 is the lower inner wall surface of the stopper groove 12.

In some embodiments, as shown in fig. 4 and 11, the inner wall surface of the limiting groove 12 is a cambered surface, and the elastic limiting member 22 is fitted into the limiting groove 12.

In these embodiments, by configuring the entire inner wall surface of the stopper groove 12 as a smoothly-transitional arc surface, the guide surface can be naturally formed, and the processing is facilitated. The elastic limiting part 22 is in a shape matched with the elastic limiting part, so that the two parts are fully contacted, reliable limiting is facilitated, the stirring head is prevented from falling off in the using process, the elastic limiting part 22 also has an arc surface, a guiding effect can be achieved, and convenient and fast disassembly and assembly of the stirring head are further guaranteed.
