[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0028] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] See also Figure 1 An embodiment of the present application provides a stirring tool, including a mounting base 1, a first blade 2 and a second blade 3. The first blade 2 and the second blade 3 are both rotatably connected to the mounting base 1, and the rotation space of the first blade 2 and the rotation space of the second blade 3 partially overlap.

[0031] In actual application, the first blade 2 and the second blade 3 are usually arranged in parallel along the mounting seat 1, and the first blade 2 and the second blade 3 can be inclined toward the outside of the mounting seat 1. Such an arrangement can expand the overlapping range of the first blade 2 and the second blade 3, and the rotation spaces of the first blade 2 and the second blade 3 intersect, and the rotation of the first blade 2 and the second blade 3 does not interfere with each other, so that the rotation spaces of the first blade 2 and the second blade 3 can overlap to a certain extent, increasing the effective area of ​​the blades and the food, thereby generating a greater stirring force; and the intersecting rotation spaces can allow the airflows of the first blade 2 and the second blade 3 to interact with each other, reduce the generation of vortices, further improve the stirring effect, and reduce noise.

[0032] Compared with the prior art, the present application intersects the rotation space of the first blade 2 and the second blade 3, thus expanding the stirring range of the first blade 2 and the second blade 3. During the stirring operation, more ingredients can be simultaneously acted on, and the stirring dead angle is reduced, so that the ingredients can be stirred more quickly and more comprehensively in the stirring container, thereby improving the overall stirring efficiency. In addition, the partial overlap of the first blade 2 and the second blade 3 can reduce the installation space of the first blade 2 and the second blade 3, saving the volume of the stirring tool; at the same time, since the areas of the first blade 2 and the second blade 3 overlap to a certain extent, the action area of ​​the blade and the food is increased, and the stirring force is increased. Therefore, the present application can use a low-speed drive to drive the blade to rotate, so as to achieve a low-speed and high-efficiency stirring effect, save economic costs, and the low speed is conducive to reducing working noise and improving the actual user experience.

[0033] See again Figure 1 The first blade 2 has at least two first cutting edges 22 arranged along the circumferential direction, and the second blade 3 has at least two second cutting edges 32 arranged along the circumferential direction. The first cutting edges 22 and the second cutting edges 32 alternately pass through a preset overlapping space.

[0034] In practical applications, the overlapping part of the rotation space of the first blade 2 and the rotation space of the second blade 3 forms an overlapping space, and the first blade 2 includes at least two first cutting edges 22. Taking the first blade 2 including two first cutting edges 22 as an example, the two first cutting edges 22 are arranged at an interval of 180 degrees, so that the first blade 2 formed is in the shape of a strip, and the shape of the second blade 3 can be the same or similar to the first blade 2, so that the long strip-shaped first blade 2 or the second blade 3 can sweep a larger area when rotating, and the contact area with the food is also increased accordingly, reducing the separation of airflow and the generation of eddy currents. The eddy currents generated by the long strip-shaped first blade 2 and the second blade 3 when rotating are relatively regular and stable, and the intensity and range of the eddy currents are relatively small, which helps to reduce the influence of the eddy current on the surrounding airflow, reduce noise, and increase the stirring range. In some embodiments, three first cutting edges 22 can be provided, and the three first cutting edges 22 are arranged at an interval of 120 degrees along the circumferential direction.

[0035] At the same time, the first blade 2 and the second blade 3 pass through the overlapping space successively, so that the food flowing through the area can be acted upon by the first blade 2 and the second blade 3 successively, and the airflows in the overlapping space complement and coordinate with each other, which can make the food flow more smoothly, reduce the generation of eddy currents, and thus reduce working noise.

[0036] It should be noted that the number of the first cutting edges 22 and the second cutting edges 32 can be an even number, so as to form a plurality of long strip-shaped blades.

[0037] See also Figure 2 The stirring tool includes a first rotating shaft 4 and a second rotating shaft 5, both of which are rotatably connected to the mounting base 1, the first blade 2 is connected to the first rotating shaft 4, the second blade 3 is connected to the second rotating shaft 5, and the angle between the first rotating shaft 4 and the second rotating shaft 5 is greater than or equal to 60 degrees and less than 180 degrees.

[0038] In practical applications, since the first blade 2 and the second blade 3 are usually inclined toward the outside of the mounting seat 1, the airflow of the first blade 2 and the second blade 3 can form a specific flow trajectory above the mounting seat 1, reducing mutual interference and turbulence. Compared with the first blade 2 and the second blade 3 arranged in parallel, the inclined first blade 2 and the second blade 3 can allow the airflow to pass more smoothly during stirring, reducing the aerodynamic noise caused by airflow disturbance.

[0039] In addition, the first blade 2 and the second blade 3 are inclined outward, which increases the safety distance between the first blade 2 and the second blade 3, expands the stirring range of the first blade 2 and the second blade 3, and also has enough space to avoid the first blade 2 and the second blade 3 from interfering with each other.

[0040] Based on this, the present application controls the angle between the first rotating shaft 4 and the second rotating shaft 5 to be between 60 degrees and 180 degrees. For example, the angle between the first rotating shaft 4 and the second rotating shaft 5 can be 60 degrees, 70 degrees, 90 degrees, 100 degrees, 120 degrees, 135 degrees, etc. This can provide more space and convenience for the structural arrangement of the stirring tool, and facilitate avoiding interference between the first blade 2 and the second blade 3.

[0041] See again Figure 2 The stirring tool has a driving component (not shown in the figure), which is connected to the first rotating shaft 4 and the second rotating shaft 5 and is used to drive the first blade 2 and the second blade 3 simultaneously or separately.

[0042] In one embodiment, the driving component is used to provide power or to connect the power component so that the first blade 2 and the second blade 3 rotate to achieve the stirring function. The driving component can be a motor, and the driving component can be connected to the first rotating shaft 4 and the second rotating shaft 5 respectively to drive the first rotating shaft 4 and the second rotating shaft 5 to rotate, and then the first rotating shaft 4 and the second rotating shaft 5 drive the first blade 2 and the second blade 3 to rotate, so as to achieve the function of driving the first blade 2 and the second blade 3 to rotate. In this way, the layout of the first rotating shaft 4 and the second rotating shaft 5 is more reasonable, and the weight design of the stirring tool is more balanced.

[0043] In other embodiments, the driving component can be connected to one of the first rotating shaft 4 or the second rotating shaft 5, and then the first rotating shaft 4 and the second rotating shaft 5 are connected in a transmission manner, for example, by meshing a transmission gear set, so that the first rotating shaft 4 and the second rotating shaft 5 can transmit a rotational force, and when one of the first rotating shaft 4 and the second rotating shaft 5 rotates, the other can also rotate accordingly, so as to drive the first blade 2 and the second blade 3 to rotate. In this way, the driving component only needs to be connected to one of the first rotating shaft 4 and the second rotating shaft 5, and the connection method is simple and easy to install.

[0044] See again Figure 2 The driving component includes a driving member, the first rotating shaft 4 is connected to a first gear 41, the second rotating shaft 5 is connected to a second gear 51, the first gear 41 and the second gear 51 are meshed, and one of the first rotating shaft 4 and the second rotating shaft 5 is connected to the driving end of the driving member.

[0045] In practical applications, the driving member can be connected to one of the first rotating shaft 4 and the second rotating shaft 5, and the first rotating shaft 4 and the second rotating shaft 5 are meshed together through the first gear 41 and the second gear 51. When the driving member drives one of the first rotating shaft 4 and the second rotating shaft 5 to rotate, the other one also rotates accordingly, so as to realize the stirring function of the first blade 2 and the second blade 3. At the same time, since the first rotating shaft 4 and the second rotating shaft 5 are meshed, the first blade 2 and the second blade 3 rotate in opposite directions. When the first blade 2 and the second blade 3 successively pass through the overlapping space, the counter torques they generate are interlaced in time and space, and can more effectively offset each other, so that the mounting seat 1 maintains a stable posture, reduces the shaking of the mounting seat 1, and thus avoids violent vibration when the stirring tool is working, and avoids damage to the device after long-term use. The driving member can be a motor.

[0046] See again Figure 2 The driving component includes a driving member and a driving shaft 7. The driving shaft 7 is rotatably connected to the mounting base 1. The driving shaft 7 is connected to the driving member. The driving shaft 7 is connected to a main gear 71. The first rotating shaft 4 is connected to a first gear 41. The second rotating shaft 5 is connected to a second gear 51. The first gear 41 and the second gear 51 are respectively arranged on both sides of the main gear 71. The main gear 71 is meshed with the first gear 41 and the second gear 51 at the same time.

[0047] In actual application, the first rotating shaft 4 and the second rotating shaft 5 are respectively arranged on both sides of the driving shaft 7, the first gear 41 on the first rotating shaft 4 is meshed with the main gear 71 on the driving shaft 7, and the second gear 51 on the second rotating shaft 5 is meshed with the main gear 71 on the driving shaft 7. When the driving member drives the driving shaft 7 to rotate, the main gear 71 simultaneously drives the first gear 41 and the second gear 51 to rotate, so as to realize the rotation of the first rotating shaft 4 and the second rotating shaft 5, and then realize the stirring function of the first blade 2 and the second blade 3. In this way, the first rotating shaft 4 and the second rotating shaft 5 can be symmetrically arranged on both sides of the driving shaft 7, so that the weight of the stirring tool can be balanced and the amplitude of the vibration of the stirring tool can be reduced.

[0048] In one embodiment, the main gear is meshed with one of the first gear 41 and the second gear 51, and the first gear 41 is meshed with the second gear 51. In this way, the main gear 71 can drive the first gear 41 and the second gear 51 to rotate, and the meshing of the first gear 41 and the second gear 51 can realize that the first blade 2 and the second blade 3 rotate in opposite directions, which is conducive to reducing noise.

[0049] In one embodiment, the stirring tool may further include a third blade, which is rotatably connected to the mounting base 1, and at least one of the rotation space of the first blade 2 and the rotation space of the second blade 3 partially overlaps with the rotation space of the third blade.

[0050] In actual applications, the stirring tool can be provided with multiple blades, for example, three blades, and the rotation space of the third blade partially overlaps with the first blade 2 or the second blade 3, which can further expand the stirring range. Specifically, the stirring tool can also include a third rotating shaft, which is rotatably connected to the mounting base 1, and a third gear is connected to the third rotating shaft. The third gear is meshed with one of the main gear, the first gear 41 and the second gear 51 to realize the rotation of the third blade.

[0051] The third blade can also be connected to the driving shaft 7. When the driving shaft 7 rotates, the driving shaft 7 drives the third blade to rotate. This arrangement can save the number of rotating shafts and there is no need to set up an additional third rotating shaft.

[0052] See again Figure 2 A first rotating hole 21 is opened at the symmetric center of the first blade 2 , a second rotating hole 31 is opened at the symmetric center of the second blade 3 , the first rotating shaft 4 is inserted into the first rotating hole 21 , and the second rotating shaft 5 is inserted into the second rotating hole 31 .

[0053] In practical applications, the first rotating shaft 4 is set at the center of the first blade 2, and the second rotating shaft 5 is set at the center of the second blade 3, so that when the first blade 2 and the second blade 3 rotate, the airflow can flow evenly through the blade surface to form a stable airflow field, which helps to reduce airflow separation and the generation of vortices, and reduce aerodynamic noise and vibration.

[0054] The embodiment of the present application further provides a stirring device, comprising the above-mentioned stirring tool and a stirring cup 6, wherein the mounting base 1 is assembled in the stirring cup 6, and the stirring cup 6 has a stirring cavity for at least part of the stirring tool to extend into.

[0055] In actual application, the mounting base 1 of the stirring tool needs to be installed in the stirring cup 6, the stirring chamber of the stirring cup 6 is used to load food, and the first blade 2 and the second blade 3 extend into the stirring chamber to facilitate the first blade 2 and the second blade 3 to cut the food in the stirring cup 6.

[0056] See also Figure 3 The inner diameter of the mixing cup 6 is D, the lengths of the first blade 2 and the second blade 3 are both less than L, and L≤0.7D.

[0057] In actual applications, in order to expand the stirring range of the first blade 2 and the second blade 3 and avoid interference between the first blade 2 and the second blade 3 and the stirring cup 6, the length of the first blade 2 and the second blade 3 shall not exceed 0.7 times the inner diameter of the stirring cup 6. For example, the length of the first blade 2 and the second blade 3 is 0.5D, 0.6D or 0.7D. At this time, the first rotating shaft 4 and the second rotating shaft 5 can be symmetrically arranged on both sides of the driving shaft 7, and the angle between the first rotating shaft 4 and the driving shaft 7 is α, which can be between 30 degrees and 60 degrees, and α is preferably 45 degrees.

[0058] In one embodiment, see Figure 4 The rotation space of the first blade 2 and the rotation space of the second blade 3 of the present application may intersect in space to form an overlapping space, and the first blade 2 and the second blade 3 may be rotated to the overlapping space one after another. The areas of the first blade 2 and the second blade 3 overlap to a certain extent, and a low-speed high-efficiency stirring effect is achieved.

[0059] In one embodiment, see Figure 5 In the present application, the rotation space of the first blade 2 and the rotation space of the second blade 3 may also intersect in projection to form an overlapping space, that is, the rotation space of the first blade 2 and the rotation space of the second blade 3 do not intersect in space. In this way, the first blade 2 and the second blade 3 may be rotated to the overlapping space at the same time, and an effect similar to that of the above embodiment may be achieved.

[0060] In one embodiment, the rotation directions of the first blade 2 and the second blade 3 can be the same or opposite. For example, the first gear 41 and the second gear 51 are engaged, so that the first blade 2 and the second blade 3 rotate in opposite directions; for example, the first gear 41 and the second gear 51 are respectively engaged with the main gear, so that the first blade 2 and the second blade 3 rotate in the same direction.

[0061] In one embodiment, the rotation speeds of the first blade 2 and the second blade 3 may also be the same or different. The rotation speeds of the first blade 2 and the second blade 3 can be adjusted by adjusting the transmission ratio between the first gear 41 and the main gear, and the transmission ratio between the second gear 51 and the main gear.

[0062] Different from the prior art, the embodiment of the present application provides a stirring tool and a stirring device, wherein the stirring tool comprises a mounting seat 1, a first blade 2 and a second blade 3, the first blade 2 and the second blade 3 are both rotatably connected to the mounting seat 1, and the rotation space of the first blade 2 and the rotation space of the second blade 3 partially overlap. Compared with the prior art, the present application intersects the rotation spaces of the first blade 2 and the second blade 3, thereby expanding the stirring range of the first blade 2 and the second blade 3, and can act on more ingredients at the same time during the stirring work, reducing the stirring dead angle, so that the ingredients can be stirred more quickly and more comprehensively in the stirring container, thereby improving the overall stirring efficiency. Moreover, the partial overlap of the first blade 2 and the second blade 3 can reduce the installation space of the first blade 2 and the second blade 3, saving the volume of the stirring tool; at the same time, since the areas of the first blade 2 and the second blade 3 overlap to a certain extent, the action area of ​​the blade and the food is increased, and the stirring force is increased, so the present application can use a low-speed driving member to drive the blade to rotate, so as to achieve a low-speed and high-efficiency stirring effect, save economic costs, and the low speed is conducive to reducing working noise and improving the actual use experience of users.

[0063] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
