Description

Technical Field

[0001] The present invention relates to the technical field related to mechanical transmission, and in particular to a transmission mechanism for realizing spherical revolution, and a blender, a camera, and a massager having the transmission mechanism. Background Art Background technology 1

[0003] A transmission mechanism is a component or mechanism that transfers power from one part of a machine to another, causing the machine or its parts to move or operate. The selection of a transmission mechanism should be based on actual conditions and appropriate transmission mechanisms should be selected according to the occasion.

[0004] A spherical circle refers to the intersection circle when a sphere intersects a plane in space. It is a transmission mechanism that converts rotational motion into a revolving motion with a spherical circle as the motion trajectory. It has certain advantages in the selection of some transmission mechanisms.

[0005] Therefore, it is very necessary to design a transmission mechanism that can realize spherical revolution. Background technology 2

[0007] A mixer typically uses a drive unit to drive the agitator shaft, which in turn rotates the agitator blades within the mixing drum to achieve mixing. Zhu Wenmei, "Analysis of the Motion Trajectory of Planetary Concrete Mixer Blades [J]," Construction Mechanization, Issue 10, 1987, states: "To ensure uniform distribution of the mixture's components, the particles must be given specific motion trajectories, with the motion trajectories of the components intersecting to the greatest extent possible. Clearly, the more particles intersecting, the more intense the mixing process and the better the homogeneity."

[0008] In the existing technology, the motion trajectory of the stirring blade is a rotational motion on a two-dimensional plane, which is not conducive to the upward and downward flow of materials. In addition, the mixer usually rotates in one direction, and the material and the stirring blade are prone to synchronous motion. There are fewer particles in cross-motion, and the stirring process is not strong, which affects the stirring homogeneity. For projects that require parallel testing, multiple mixers need to be purchased, which increases costs and wastes space.

[0009] Therefore, it is very necessary to design a mixer that can not only improve the mixing homogeneity but also perform parallel tests. Background technology 3

[0011] Cameras are a widely used type of surveillance equipment, categorized as fixed cameras and rotating cameras. Fixed cameras are often used for fixed-point surveillance of small areas. The camera's viewing angle remains fixed, resulting in a small monitoring range and blind spots. To avoid these blind spots, some situations require the installation of two or more fixed cameras, which in turn increases the number of monitoring windows. This not only increases costs but also makes viewing more difficult, hindering management. Rotating cameras are often used for monitoring large areas. The camera's viewing angle rotates, resulting in a large monitoring range and blind spots. For example, when the camera is rotated to the left, the area that cannot be seen on the right is a blind spot. When the camera is rotated to the right, the area that cannot be seen on the left is a blind spot.

[0012] In actual applications, this situation often occurs: when using fixed cameras for monitoring, there are always some places that cannot be monitored. When adding a fixed camera or using a rotating camera for monitoring, the cost is too high.

[0013] Therefore, it is very necessary to design a camera that can expand the monitoring range and avoid monitoring blind spots. Background technology 4

[0015] A massager is a device used to promote blood circulation and protect physical health. Since the massage process is achieved by squeezing the contacts on the massage head when they come into contact with the human body, the degree of fit between the contacts on the massage head and the contact parts of the human body is one of the important factors affecting the massage effect.

[0016] On the market, the contacts on massage heads are universally designed for a wide range of people. However, in real life, everyone's height, weight, and body structure are different. It is difficult for the contacts on the massage head to achieve an ideal match with the contact parts of the human body, which in turn affects the massage effect. In addition, current massagers are usually designed for a specific part of the human body and are only limited to use on specific parts. They are not universal, so different parts of the human body require different types of massagers.

[0017] Therefore, it is very necessary to design a massager that can not only improve the massage effect but also have versatility. Summary of the Invention

[0048] Among them, the rotating shaft 1 is installed in the rotating shaft bearing 6.
