[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a rapid cooling system for an angle grinder, comprising an angle grinder 1 and an isolation sleeve 4, wherein the isolation sleeve 4 is arranged on the outside of the angle grinder 1, a U-shaped plate 5 is installed at one end of the isolation sleeve 4, the U-shaped plate 5 is sleeved on the outside of the battery at one end of the angle grinder 1, and is arranged to press the battery toward the angle grinder 1, a water filling pipe 6 is installed on the top surface of the isolation sleeve 4, a grinding disc 2 is installed at the other end of the angle grinder 1, a protective cover 3 is installed on the outside of the grinding disc 2, the upper wall of the protective cover 3 is thickened, a cavity is formed inside the upper wall of the protective cover 3, a plurality of water outlet holes 13 for cooling the grinding disc 2 are provided on the inner side surface of the protective cover 3, and a connecting pipe 11 is installed between the isolation sleeve 4 and the protective cover 3.

[0021] In this embodiment, the inner side surface of the isolation sleeve 4 is arranged to abut against the outer wall surface of the angle grinder 1, and a water storage chamber with an annular structure is formed inside the isolation sleeve 4. The water adding pipe 6 is longitudinally arranged above the isolation sleeve 4 in an "L"-shaped structure. The end of the water adding pipe 6 away from the isolation sleeve 4 is bent upward and is equipped with a water adding bucket 7. A sealing plug 8 is threadedly connected to the opening at the upper end of the water adding bucket 7.

[0022] In this embodiment, the connecting pipe 11 includes an inlet pipe 10, an outlet pipe 9, a control valve 12 and a connecting pipe 11. The outlet pipe 9 is installed on the bottom surface of the isolation sleeve 4, the inlet pipe 10 is installed on the protective cover 3 and is connected to the cavity. The other ends of the inlet pipe 10 and the outlet pipe 9 are both in contact with each other. The connecting pipe 11 is sleeved at the connection between the inlet pipe 10 and the outlet pipe 9, and is threadedly connected to the inlet pipe 10 and the outlet pipe 9. The control valve 12 is installed in the middle of the outlet pipe 9.

[0023] In this embodiment, the isolation sleeve 4 is made of plastic material, and a metal sheet is embedded on the inner side of the isolation sleeve 4. One side of the metal sheet is in contact with the outer wall of the angle grinder 1, and the other side extends into the water storage chamber. The metal sheet can absorb the heat from the angle grinder and conduct the heat to the water to achieve the function of heat dissipation and cooling.

[0024] In this embodiment, the corners of the isolation sleeve 4 are chamfered to increase the comfort when holding the device.

[0025] In this embodiment, the connecting pipe 11 is made of metal material, which increases the firmness and stability of the connection.

[0026] When in use, the isolation sleeve can be directly sleeved on the outside of the grinder until the water outlet pipe is against the water inlet pipe. At this time, the connecting sleeve can be rotated so that the two ends of the connecting sleeve can be threadedly connected to the water inlet pipe and the water outlet pipe to complete the fixation of the two and the isolation sleeve. After the isolation sleeve is moved into place, the U-shaped plate can be sleeved on the outside of the battery and the battery is pressed and fixed, thereby increasing the stability of the battery.

[0027] The water adding pipe is arranged in an "L"-shaped structure. During use, the water adding pipe can be used as a grip. The angle grinder can be pressed down by holding the water adding pipe. The water adding pipe of this structure facilitates the water filling operation. When filling water, the water adding pipe can be moved to the bottom of the faucet, while the angle grinder itself is far away from the faucet, so that the water flow can avoid the angle grinder during the water filling process, avoiding the water flow from pouring on the angle grinder, thereby increasing safety.

[0028] After the water injection is completed, the control valve can be opened, and the speed of water discharge can be changed through the control valve, so that the water inside the isolation sleeve can enter the cavity along the water inlet pipe and the water outlet pipe until it is discharged from the water outlet hole. The discharged water can contact the grinding disc, so that the grinding disc can be continuously cooled;

[0029] The isolation sleeve can isolate the heat from the handle and cool the angle grinder itself.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
