Description

Technical Field

[0001] The utility model relates to the field of cooking accessories, in particular to a stirring rod. Background Art

[0002] Most electric stirring rods on the market adopt an oval design, and the contact area with the bottom of the container is limited. Especially when stirring easy-to-precipitate materials such as milk powder, the stirring rod often cannot fully reach and stir the sediment at the bottom of the container, resulting in uneven mixing. Due to the shape of the stirring rod and the transparency of the stirring material, it is difficult for users to intuitively judge whether the stirring rod has effectively contacted the bottom of the container during operation. They often increase the pressure to force the stirring rod to stick to the bottom, which increases the friction between the stirring rod and the bottom of the container, thereby increasing the workload of the motor. Excessive friction will cause the motor load to increase significantly, which may not only shorten the service life of the motor, but in extreme cases may even cause the motor to stop running due to overload. In order to solve the problem of insufficient stirring at the bottom, some stirring rods try to design the ends to be relatively flat to increase the contact area with the bottom of the container, but this will further increase the friction. Not only does it fail to effectively solve the original problem, but it may also aggravate the motor load and uneven stirring, highlighting the defects of the existing design. Utility Model Content

[0003] The purpose of the utility model is to provide a stirring rod to solve at least one of the above problems.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A stirring rod comprises a stirring shaft, one end of which has a connection end connected to an output end of a transmission device, and the other end of which is connected to a stirring head, wherein the stirring head comprises stirring blades, and the stirring blades comprise outward-spreading blades for extending a stirring radius and extending a stirring depth; the lower end of the stirring blades is the bottom end of the stirring head. An external contact convex body is arranged at the bottom end of the stirring head, and the external contact convex body is connected to the stirring blades.

[0006] Furthermore, the outer contact protrusion and the stirring blade are an integrally formed structure.

[0007] Furthermore, the external contact protrusion and the stirring blade are separate structures, and the external contact protrusion is fixedly connected to the stirring blade.

[0008] Furthermore, the external contact protrusion and the stirring blade are separate structures, and the external contact protrusion and the stirring blade are detachably connected.

[0009] Furthermore, the stirring head, the stirring shaft and the connecting end thereof are an integrally cast structure.

[0010] Furthermore, the bottom of the outer contact protrusion is a curved surface, and the bottom of the outer contact protrusion can touch the inner bottom of the container containing the object to be stirred.

[0011] Furthermore, the overall shape of the outer contact protrusion is a sphere, and the bottom of the outer contact protrusion can touch the inner bottom of the container containing the material to be stirred.

[0012] Furthermore, the stirring blade is provided with a mounting groove for accommodating the external contact protrusion, and an elastic component is connected between the external contact protrusion and the stirring blade.

[0013] Furthermore, when the elastic component is in the extended state and the contracted state, the external contact protrusion protrudes outward from the bottom end of the stirring head, so that when the stirring rod is extended into the container containing the object to be stirred, the external contact protrusion contacts the inner bottom of the container containing the object to be stirred before the bottom end of the stirring head.

[0014] Furthermore, the outward convex height of the external contact protrusion when the elastic component is in the extended state is greater than the outward convex height of the elastic component when the elastic component is in the contracted state.

[0015] Analysis shows that the utility model discloses a stirring rod, the outer contact protrusion arranged at the bottom end of the stirring head of which can contact the inner bottom surface of the container before the bottom end of the stirring blade, thereby effectively reducing the contact area between the stirring head and the container, preventing the stirring rod from directly contacting the bottom of the container during rotation, thereby increasing its friction, resulting in an increase in the load of the stirring motor, thereby affecting the life of the motor.

Similar or similar marks in the drawings and descriptions have been used to refer to similar or similar parts of the utility model. As used herein, the terms "first", "second", and "third" etc. are used interchangeably to distinguish one component from another, and are not intended to indicate the position or importance of individual components.

[0029] like Figure 1 to Figure 2As shown, according to the first embodiment of the present invention, a stirring rod is provided, including a stirring shaft 2, one end of the stirring shaft 2 has a connecting end 3 connected to the output end of the stirrer, and the other end of the stirring shaft 2 is connected to a stirring head 1, and the stirring head 1, the stirring shaft 2 and its connecting end 3 are an integrally cast structure.

[0030] The stirring head 1 includes a stirring blade 12, and the overall shape of the stirring blade 12 can be set to be elliptical, circular, fan-shaped or other outward-expandable blade shapes. The outward-expanded shape helps to expand the stirring radius and stirring depth of the stirring head when the stirring shaft 2 is in a rotating use state.

[0031] The lower end of the stirring blade 12 is the stirring head bottom 10. The stirring head bottom 10 is provided with an external contact convex body 11, which can be convexly arranged at the symmetrical center point of the stirring head bottom 10, and the external contact convex body 11 and the stirring blade 12 are an integrally formed structure.

[0032] The bottom of the external contact protrusion 11 is made of a flexible material with an arc surface or a spherical surface. The bottom of the external contact protrusion 11 can contact the inner bottom of the container containing the object to be stirred, so that when the stirring rod is extended into the container containing the object to be stirred, the external contact protrusion 11 contacts the inner bottom of the container containing the object to be stirred before the bottom end 10 of the stirring head.

[0033] like Figure 3-Figure 4 As shown, in the second embodiment, the external contact protrusion 11 and the stirring blade 12 disclosed in the present application are a split structure, and the split structure enables the external contact protrusion 11 and the stirring blade 12 to be disassembled independently, which is easier to clean and disinfect, especially for industries such as food processing and biopharmaceuticals, which can effectively prevent pollution and cross infection and meet hygiene requirements. The external contact protrusion 11 is fixedly connected to the stirring blade 12. The stirring head 1 and the stirring shaft 2 can also be a detachably connected structure, and one end of the stirring shaft 2 has a connecting rod 21, which is detachably connected or fixedly connected to the inner circumference of the elliptical stirring blade 12. When the stirring blade 12 is worn or needs to be replaced with a different type of stirring blade 12 to meet different stirring needs, the detachable design makes it very convenient to replace the stirring blade 12, without replacing the entire stirring head 1, reducing maintenance and update costs.

[0034] like Figure 5-Figure 6As shown, in the third embodiment, the outer contact protrusion 11 and the stirring blade 12 can be a split structure, and the outer contact protrusion 11 and the stirring blade 12 are detachably connected. The overall shape of the outer contact protrusion 11 is a flexible material of a sphere, and the bottom of the outer contact protrusion 11 can touch the inner bottom of the container containing the object to be stirred. The stirring blade 12 of the present application also includes a mounting groove 110, which is used to place the outer contact protrusion 11. An elastic component 4 is also connected between the outer contact protrusion 11 and the stirring blade 12. When the elastic component 4 is in the extended state and the contracted state, the outer contact protrusion 11 protrudes outward from the bottom end 10 of the stirring head, so that when the stirring rod is extended into the container containing the object to be stirred, the outer contact protrusion 11 contacts the inner bottom of the container containing the object to be stirred before the bottom end 10 of the stirring head. The convex height of the outer contact protrusion 11 when the elastic component 4 is in the extended state is greater than the convex height of the elastic component 4 when it is in the contracted state. The elastic component 4 can be an elastic device with telescopic function such as a metal spring, a plastic spring, a rubber spring, a liquid-gas spring, etc.

[0035] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0036] 1. An external contact protrusion 11 is provided at the bottom of the stirring head 1. The bottom of the external contact protrusion 11 is a sphere or an arc. The spherical external contact protrusion can make adaptive contact according to the shape of the bottom of the container. Even if the shape of the bottom of the container is slightly uneven, the contact area can be reduced as much as possible to enhance the stirring stability. In addition, a good contact and transmission mechanism can reduce the kinetic energy loss caused by the gap, and indirectly reduce the energy consumption during the stirring process.

[0037] 2. The external contact protrusion 11 is detachably connected to the stirring blade 12 through the elastic component 4. By setting the external contact protrusion 11, when the stirring rod is inserted into the container, the external contact protrusion 11 contacts the bottom of the container before the bottom end 10 of the stirring head, which can play a buffering role and prevent the stirring head from directly hitting the bottom of the container and causing damage, while also protecting the stirring device itself from impact damage.

[0038] 3. The elastic force provided by the elastic component 4 enables the outer contact protrusion 11 to adaptively expand and contract to a certain extent according to the actual situation of the bottom of the container, so that when the outer contact protrusion 11 contacts the inner bottom of the container, the stirring efficiency and stirring effect can be improved, especially when the bottom of the container is uneven, it can better fit the bottom of the container for stirring.

[0039] 4. The elastic component 4 is arranged in the mounting groove 110 at the bottom end of the stirring blade 12, which helps to absorb part of the vibration and impact generated during the stirring process, reduce the operating noise, and improve the stability of the equipment operation and the service life.

[0040] 5. The outer contact protrusion 11 arranged at the bottom end of the stirring head 1 of the stirring rod can contact the inner bottom surface of the container before the bottom end of the stirring blade 12, which can effectively reduce the contact area between the stirring head 1 and the container, and prevent the stirring rod from increasing its friction with the bottom of the container during rotation, resulting in an increase in the load of the stirring motor, thereby affecting the life of the motor.

[0041] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
