[0002] Existing nail grinders generally have a debris bin for collecting debris. However, the debris typically falls into the debris bin under gravity, inevitably resulting in some debris adhering to the grinding disc or the channel leading into the debris bin. For example, Chinese Patent No. ZL201811340987.6 discloses a nail grinder comprising: an outer shell, an inner shell, a cutting head, a motor, and a debris storage bin; the inner shell is housed within the outer shell and includes: a first inner shell and a second inner shell cooperating with the first inner shell; the motor is housed and installed in the upper chamber of the inner shell; the cutting head has a working surface and a connecting surface opposite to the working surface, the connecting surface being connected to the motor via a connecting rod; the cutting head and the motor are located within the inner shell and move synchronously axially with the inner shell; one end of the debris storage bin is housed and installed within one end of the inner shell, the other end of the debris storage bin protruding from the inner shell, and the cutting head is housed within the debris storage bin.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a grinding tool for collecting grinding debris. An airflow drive is provided between the grinding debris chamber and the debris bin to drive the airflow. The airflow drive drives the gas in the grinding debris chamber into the debris bin, preventing the grinding debris from adhering to the grinding debris chamber and the first dust suction air duct, so that the grinding debris generated by the grinding tool is collected on the debris bin.

[0005] The purpose of this utility model is achieved as follows:

[0006] A grinding tool for collecting grinding debris includes a body with a grinding debris chamber and a debris bin for collecting the debris. An airflow drive is provided between the grinding debris chamber and the debris bin to drive airflow. The airflow drive is provided with a first dust suction duct connecting the grinding debris chamber and the debris bin. The debris on the grinding debris chamber enters the debris bin along the first dust suction duct under the suction action of the airflow drive. By providing an airflow drive to drive airflow, the debris is prevented from adhering to the grinding debris chamber and the first dust suction duct, so that the debris generated after grinding by the grinding tool is collected on the debris bin.

[0007] The armor grinding debris chamber is provided with a first air guide slope. Under the action of the airflow driving component, the gas in the armor grinding debris chamber enters the first debris suction air duct through the first air guide slope, so that the armor grinding debris chamber forms a negative pressure chamber for adsorbing debris.

[0008] During operation, the airflow drive unit uses centrifugal force to move the air in the armor grinding debris chamber toward the first guide slope, creating a downward suction force at the armor grinding plate, causing the debris to enter the first debris suction air duct, and then collecting the debris into the debris bin.

[0009] The debris bin is installed on the machine body in a movable or detachable manner; and the debris bin is provided with a vent that connects the outside air to the first debris suction duct, or the machine body is provided with a door for opening and closing the debris bin, and the door is provided with a vent.

[0010] A vent is provided that connects to the debris bin, allowing air driven by the airflow drive to be discharged from the vent into the outside air.

[0011] The airflow drive component is a fan wheel or fan blade. The machine body is equipped with a driver and transmission mechanism for driving the airflow drive component, and the nail grinding assembly for grinding nails is located on the nail grinding chip chamber. The airflow drive component and the nail grinding assembly are respectively connected to the driver through the transmission mechanism. When the driver is running, it drives the airflow drive component and the nail grinding assembly to move through the transmission mechanism, so that the airflow drive component and the nail grinding assembly share a single driver. Only one driver is needed to drive the airflow drive component and the nail grinding assembly to move. This has the effects of saving production costs, reducing the size of the nail grinder, making the internal structure of the nail grinder compact, and achieving energy saving in the nail grinder.

[0012] The airflow drive unit is located in the lower part of the armor grinding assembly and the armor grinding debris chamber.

[0013] The transmission mechanism includes a first gear that is connected to the airflow drive component. The first gear is provided with a second dust suction duct that connects to the first dust suction duct. The debris on the armor grinding debris chamber enters the debris bin along the second dust suction duct and the first dust suction duct under the suction action of the airflow drive component.

[0014] The machine body is provided with a transmission mechanism box for accommodating and installing the transmission mechanism. The transmission mechanism includes a first gear that is connected to the airflow drive component and is mounted on the transmission mechanism box. The first gear is provided with a second chip suction duct. A sealing element is provided inside the transmission mechanism box. One end of the sealing element abuts against the inner side of the transmission mechanism box, and the other end of the sealing element abuts against the first gear, so that a relatively sealed second chip suction duct is formed between the transmission mechanism box and the first gear, preventing chip material from leaking out of the second chip suction duct with the gas.

[0015] The second chip suction duct is located above the first chip suction duct, and the first gear is provided with a second air guide slope that forms the first chip suction duct. Under the action of the airflow drive, the gas in the armor grinding chip chamber enters the second chip suction duct and the first chip suction duct through the first air guide slope and the second air guide slope. During the operation of the airflow drive, the airflow drive drives the gas in the second chip suction duct to move towards the second air guide slope through the action of centrifugal force, forming a downward suction force at the armor grinding chip chamber, so that the chips generated after the armor grinder grinds are collected on the chip bin along the second chip suction duct and the first chip suction duct.

[0016] The unit is equipped with a power supply module for providing power to the driver. The power supply module can be a power socket that connects to a power source or a battery that stores electricity.

[0017] The machine body is provided with a transmission mechanism box for accommodating and installing the transmission mechanism. The opening of the debris bin abuts against the transmission mechanism box so that the opening of the debris bin forms a relatively sealed debris collection chamber for collecting debris.

[0018] The machine body is provided with a pull-out opening for pulling out the debris bin. There is a limiting part between the pull-out opening and the debris bin. The debris bin is pulled out and moves on the machine body by limiting the movement of the debris bin through the limiting part. The debris bin is designed to be pull-out, but the debris bin cannot be pulled out completely. The debris can be emptied after the debris bin is pulled out.

[0019] The beneficial effects of this utility model are as follows:

[0020] An airflow drive is provided between the armor grinding chip chamber and the chip bin to drive the airflow. The airflow drive drives the gas in the armor grinding chip chamber into the chip bin, preventing the chips from adhering to the armor grinding chip chamber and the first chip suction air duct, so that the chips generated after the armor grinder grinds are collected on the chip bin.
