[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments of the invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0029] Some embodiments of the present invention include Figure 1 As shown, an impeller includes a sheet-shaped base body 1, the top surface of the base body 1 is a mounting surface, the bottom surface of the base body 1 is a working area, a plurality of liquid guides are arranged in an annular array on the working area, and all the liquid guides are arranged in an annular array around the central area of ​​the working area. In actual use, some wax water is first poured on the workpiece to be polished, and then the middle of the impeller working area is pressed on the wax water. Since all the liquid guides extend from the central area of ​​the working area to the edge of the working area, the wax water will be guided to the edge of the working area by the liquid guides, so that the lower side of the liquid guides is stained with as large an area as possible. Wax water is added to reduce the dry grinding phenomenon of the guiding liquid at the beginning of work. After the impeller rotates one circle, all the guiding liquids can be stained with wax water. The guiding liquid is a protrusion on the working area. A liquid storage groove 3 is provided between two adjacent guiding liquids. Excess wax water can be hidden in the liquid storage groove 3. During the rotation of the impeller, the wax water will be applied to the workpiece. During the continuous rotation, the guiding liquid and the workpiece rub against each other to generate heat, thereby realizing the solidification of the wax water. In this way, the wax water is reduced, and the wax water hidden in the liquid storage groove 3 will automatically replenish the wax water due to negative pressure or siphon force to ensure continuous work.

[0030] In some embodiments, Figure 1 , the central area:

[0031] Its depth is less than that of the liquid storage groove 3.

[0032] and / or,

[0033] Its lateral dimension is smaller than the width of the liquid storage groove 3;

[0034] Or, in other embodiments, Figure 2 , Figure 3 The central area: its lower side surface is arranged flush with the liquid guide.

[0035] Regardless of the structural form, the purpose is to make the siphon force of the central area on the wax water greater than the siphon force of the liquid storage groove 3 on the wax water, thereby preventing or reducing the wax water in the liquid storage groove 3 from being thrown out. Figure 1 In the central area of ​​the depression, the liquid storage grooves 3 on the left and right sides are connected. The prior art does not reasonably design the size of the central area of ​​the depression, resulting in the wax water in the two connected liquid storage grooves 3 flowing to one side under the action of centrifugal force and the negative pressure of liquid flow, which will eventually make it easy for the liquid storage groove 3 enriched with wax water to throw out the wax water, and also cause a lack of wax water replenishment on part of the liquid guide, resulting in poor polishing and grinding effects.

[0036] Because the viscosity of wax water is relatively large, in some embodiments, the depth and / or width of the liquid storage groove 3 is less than 2 mm. In this way, when the impeller is working, the cavity formed by the liquid storage groove 3 and the workpiece surface can be regarded as a siphon cavity. In addition, the negative pressure and siphon force formed by the consumption of wax water on the guiding liquid can effectively prevent the wax water in the liquid storage groove 3 from being thrown out.

[0037] The impeller often needs to rotate to achieve polishing and grinding. For this reason, the base body 1 is a circular sheet as a whole, and all the liquid guides are arranged in a circular array around the center of the cross section of the base body 1, so that the workpiece surface can be better polished and ground evenly.

[0038] In order to facilitate the wax water to enter the lower side of the liquid-conducting body, the base body 1 and the liquid-conducting body are formed in one piece, and the edge of the lower side of the liquid-conducting body is chamfered.

[0039] In some embodiments, Figure 2 , Figure 3 The liquid guide shown is divided into an island body 21 and an enclosure body 22 , at least two enclosure bodies 22 are connected in the middle of the working area, and one or more island bodies 21 are arranged between at least two connected enclosure bodies 22 .

[0040] In some embodiments, the lower side surfaces of all liquid-conducting bodies are arranged in the same plane, and the lower side surfaces of all island bodies are provided with a rough texture. The texture can be made by a sandblasting process, or it can be pre-drying on a mold for making an impeller. The formation of the texture can be appropriately selected by those skilled in the art according to the existing manufacturing process. The rough texture is easy to store wax water, and it is also convenient to generate friction and heat with the workpiece, thereby solidifying the wax water. During the solidification process of the wax water, due to the generation of negative pressure and siphon force, the wax water in the liquid storage groove 3 can be automatically replenished between the workpiece and the liquid-conducting body in a very timely manner, ensuring continuous and long-term operation.

[0041] In some embodiments, Figure 2 As shown, the number of island bodies 21 and enclosed bodies 22 is the same, the angle between two adjacent liquid storage grooves 3 is less than 180°, all the enclosed bodies 22 are connected in the middle of the working area, and an island body 21 is provided between two adjacent enclosed bodies 22. Such a structure can effectively prevent wax water from being enriched in one of the liquid storage grooves 3.

[0042] like Figure 3 , Figure 4 As shown, as some embodiments of an impeller assembly, it includes the above-mentioned impeller and also includes an elastic connecting block 6, the bottom surface of the connecting block 6 is provided with a plurality of connecting holes 4, and the mounting surface of the base body 1 is provided with a connecting buckle 5, the connecting buckle 5 extends into the connecting hole 4 and is detachably interference connected with the connecting hole 4. Compared with the connection method using Velcro or glue in the prior art, such connection is convenient and reliable, the impeller is also very convenient to replace, and the connecting block 6 can adapt well to the inclined working surface.

[0043] In some embodiments, the connecting buckle 5 is tilted, or the lateral dimension of the upper section of the connecting buckle 5 is greater than the lateral dimension of the lower section of the connecting buckle 5. Regardless of the structural setting, the connection with the connecting block 6 can be well achieved.

[0044] A waxing machine of the present invention has the beneficial effects of the above-mentioned impeller or impeller assembly because it is provided with the above-mentioned impeller or impeller assembly.

[0045] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
