[0021] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0022] See also Figures 1 to 4 The present application provides a simple maintenance tool for an expansion unit steam jet rake, comprising a cleaning head 1 and a handle 2. The cleaning head 1 and the handle 2 are connected into an integral structure by screws. When not in use, the cleaning head and the handle can also be separated. The materials of the handle and the cleaning head of the present application can be selected according to needs. For example, metal materials or plastic materials can realize the technical solution of the present application.

[0023] like Figure 1 and Figure 2As shown, the handle 2 is a circular tubular structure. In actual use, the length of the handle can be greater than the length of the cleaning head or can be equal to or less than the length of the cleaning head. The end of the handle of the present application connected to the water pipe is the front end of the handle, and the end connected to the cleaning head is the rear end of the handle. A water valve 3 is provided in the inner cavity 22 of the handle away from the cleaning head, that is, a water valve 3 is provided in the inner cavity near the rear end of the handle. The water valve 3 is used to control the water flow. The valve shaft of the water valve 3 passes through the side wall of the handle and is connected to the hand wheel 31. The end of the handle near the water valve (that is, the rear end of the handle) is connected to the water pipe. The water pipe of the present application uses a hose for easy operation. The front end of the handle is inserted into the cleaning head 1, and a threaded hole 23 is provided on the side wall. There are two threaded holes 23 in the present application, which are relatively arranged on the side wall of the handle, and the threaded holes 23 are not connected to the inner cavity 22 of the handle.

[0024] A circle of grooves 21 are arranged on the side wall of the handle near the rear end, so as to facilitate the water pipe to be put on the handle.

[0025] Two symmetrical axial grooves 24 are arranged on the side wall of the handle near the front end, and the threaded hole 23 is located on the side wall between the two axial grooves 24 .

[0026] like Figure 3 and Figure 4 As shown, the cleaning head 1 of the present application is a circular tubular structure, and a thin wall 13 with a middle through hole is arranged in the cavity of the cleaning head, dividing the cavity of the cleaning head 1 into two parts, namely an installation cavity 14 and a cleaning cavity 15, and installation holes 11 corresponding to the threaded holes 23 are arranged on the side wall corresponding to the installation cavity 14; a sealing ring 5 fitted with the thin wall is arranged in the installation cavity 14, and the sealing ring of the present application is a silicone gasket, which is used to prevent water leakage and shock absorption at the connection between the cleaning head and the handle, and the aperture of the middle through hole is larger than the diameter of the inner cavity of the handle, but smaller than the outer diameter of the handle, and a steel wire layer 4 is arranged in the cleaning cavity 15.

[0027] Two axial protrusions 12 are arranged in the installation cavity, corresponding one to one with the axial grooves 24. The steel wire layer 4 is cylindrical, installed in the cleaning cavity 15, and the steel wire layer 4 is one or two layers.

[0028] Working process:

[0029] When using the tool to maintain the steam rake nails, the staff will put the soft water pipe on the handle, and use the buckle to clamp the water pipe and the handle in the groove, rotate the hand wheel of the water valve to the closed position, insert the front end of the handle into the installation cavity of the cleaning head, and then use screws to fix the cleaning head and the handle, install the steel wire layer in the cleaning cavity of the cleaning head, and complete the assembly of the tool.

[0030] The operator puts the cleaning cavity on the steam rake nail so that the steel wire layer wraps the steam rake nail, and wipes the steam rake nail by rotating or moving the handle back and forth. At the same time, cleaning water is also passed through the wiping process to facilitate wiping and flushing away impurities with strong adhesion. The amount of cleaning water can be controlled by the water valve on the handle. After maintenance, the steel wire layer can be cleaned with a brush, and the cleaning head and handle of the tool can be disassembled for later cleaning and replacement.

[0031] The above description is only a preferred implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any improvements and replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
