The second opening 35 corresponds to the first opening 26, and the second notch 36 corresponds to the first notch 27. The fourth surface 33 is provided with a second groove 37, which communicates with the first groove 21 to form a spray chamber 22.
[0037] In this embodiment, a portion of the first surface 23 between the first groove 21 and the first opening 26 extends toward the spray plate 30 to form an assembly portion 231. A portion of the third surface 32 between the second groove 37 and the second opening 35 is recessed to form an assembly groove 321, into which the assembly portion 231 is inserted. Spray holes 31 are spaced apart at the bottom of the assembly groove 321. The cleaning device 100 also includes a sealing gasket (not shown), which is disposed between the assembly groove 321 and the assembly portion 231.

Specifically, the sealing gasket is provided with a plurality of gasket holes (not shown), and the sealing gasket has a radial direction, with the plurality of gasket holes penetrating the sealing gasket along the radial direction. Each gasket hole corresponds to one spray hole 31.
[0038] In this embodiment, the second opening 35 has a first central axis A1, and the bottom of the mounting groove 321 includes a mounting surface (not shown). The mounting surface forms an angle of 30 to 60 degrees with the first central axis A1, and the mounting surface is recessed to form a plurality of injection holes 31.

One end of each of the two secondary pipes 112 is inserted into the other two ports of the tee 113, and the other end is inserted into the feed plate 20 through the two connectors 114, and connected to the injection chamber 22. The cross-sectional dimensions of the multiple injection holes 31 are approximately the same, and the sum of the dimensions of the outlet cross-sections of the multiple injection holes 31 is less than the sum of the dimensions of the inlet cross-sections of the two secondary pipes 112, thereby ensuring the stability of the pressure and flow rate of the medium in the injection chamber 22. Specifically, the number of injection holes 31 can be 15, and the diameter of each injection hole 31 is 1.0 mm. The diameter of the air intake section of each secondary channel 112 can be 4.0 mm, so that the ratio of the sum of the dimensions of the air outlet cross sections of the 15 injection holes 31 to the sum of the air outlet cross sections of the two secondary channels 112 is about 1:2, thereby improving the medium injection efficiency and cleaning effect while ensuring stable output pressure.
[0041] Please see Figure 1 One embodiment of this application also provides a processing machine 200, including a machine spindle 201, a cleaning device 100, and a control unit. The cleaning device 100 is disposed on the machine spindle 201. The control unit is connected to the feeding assembly 10, and the control unit is used to control the opening and closing of the feeding assembly 10 to clean the positioning surface of the tool holder 202 during tool changing.
[0042] In this embodiment, the processing machine 200 also includes a solenoid valve (not shown), which is connected between the medium source and the feeding assembly 10. When the machine performs a tool change operation, the solenoid valve automatically opens to supply air or liquid, and automatically closes after the tool change is completed. Through product processing control, the positioning surface of the tool holder 202 is cleaned each time a tool is changed, and the feeding assembly 10 is closed after the tool change, repeating the cycle. This effectively avoids frequent manual intervention, improving processing efficiency and assembly accuracy.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it.
