Description

Technical Field

[0001] The utility model relates to the technical field of hand-held polishers, in particular to a novel hand-held polisher. Background Art

[0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Their working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. Some small polishing machines can be used handheld.

[0003] At present, a Chinese patent with announcement number CN220660348U discloses a handheld polisher that is easy to adjust the speed, including a handheld polisher main body. The outer surface of the handheld polisher main body of the utility model is provided with a handle, and a control panel is installed on the upper surface of the handheld polisher main body. The control panel and the control end of the handheld polisher main body are electrically connected. The outer surface of the handle is provided with an adjustment mechanism that can automatically adjust the rotation speed of the handheld polisher main body. An anti-fall mechanism is installed on the side of the adjustment mechanism close to the control panel. The rotation speed of the handheld polisher main body is adjusted by pressing the adjustment mechanism instead of manually operating the control panel, so that the user does not need to stop polishing when adjusting the rotation speed of the handheld polisher main body, thereby improving the polishing efficiency of the handheld polisher main body; the anti-fall mechanism limits the movement range of the user's hand, thereby minimizing the handheld polisher main body from slipping from the user's hand and falling to the ground during use.

[0004] When most of the existing hand-held polishers are in use, as the polishing paste is consumed, the hand-held polishers need to be frequently stopped to apply the polishing paste on the surface of the wool polishing wheel or the surface of the polishing object. This step is relatively cumbersome and affects the polishing efficiency of the object to be polished. Utility Model Content

[0044] Working principle: First, rotate the sealing cover 9, which is connected to the inside of the storage box 201 through a thread. When the sealing cover 9 is rotated, the sealing cover 9 can be moved, so that the sealing cover 9 is separated from the storage box 201, and the storage box 201 can be opened. Then, add the polishing paste into the storage box 201. When the wool polishing wheel 12 is needed to polish the object to be polished, hold the handle 8 and the non-slip handle 6, move the wool polishing wheel 12 to contact the object to be polished, and then control the air pump 202 to work. The air pump 202 can pressurize the air outside the storage box 201 and deliver it to the storage box 201. The polishing paste inside the storage box is squeezed, and the polishing paste inside the storage box 201 can be discharged from the connecting tube 203 and the conical tube 204 to the surface of the object, and then the motor 3 is controlled to rotate. The rotation of the motor 3 can drive the turntable 5 to rotate through the output shaft, and the rotation of the turntable can drive the wool polishing wheel 12 connected to the turntable 5 through the Velcro fur surface 11 and the Velcro hook surface 13 to rotate. At this time, the moving wool polishing wheel 12 can dip the polishing paste discharged from the conical tube 204 to polish the object to be polished, and the polishing paste can be continuously discharged from the inside of the conical tube 204 by the continuous operation of the air pump 202. The wool polishing wheel 12 is supplied with uninterrupted polishing work, which improves the polishing efficiency of the object to be polished, and avoids the problem that most existing hand-held polishers need to stop rotating frequently and apply polishing paste on the surface of the wool polishing wheel 12 or the surface of the polishing object as the polishing paste is consumed during use, which is a cumbersome step and affects the polishing efficiency of the object to be polished. It should be noted that after the wool polishing wheel 12 contacts the object to be polished, the tapered tube 204 will also contact the object to be polished, and the polishing paste has a certain viscosity, which can make the tapered tube 204 discharge The polishing paste can be adhered to the surface of the object to be polished in time to prevent the polishing paste from falling. Since the material of the conical tube 204 is soft rubber, the conical tube 204 can prevent scratches on the surface of the object to be polished. By lighting the lighting lamp beads 14, the polishing area can be illuminated, which is convenient for observing the polishing condition of the object to be polished. The remaining polishing paste in the storage box 201 can be observed through the visual window 10, which is convenient for judging whether polishing paste needs to be added. The wool polishing wheel 12 is connected to the turntable 5 by the Velcro fur surface 11 and the Velcro hook surface 13, so the wool polishing wheel 12 can be easily replaced.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
