[0109] In addition, the embodiment also provides a use method of the electric planer, which comprises the adjusting step of the guide ruler and the heat dissipation step of the machine body, wherein the adjusting step of the guide ruler comprises:

[0110] S-1: the user controls the electric conductor and the electric head to be in full contact or partial contact by pressing the pressing body;

[0111] S-2: on the basis of step S-1, the turbine structure and the receiving control body are selected to enter the first mode, when the driver drives the turbine to rotate, the medium in the adjusting source is discharged through the liquid outlet branch, and when the liquid inlet electromagnetic valve is opened and the liquid outlet electromagnetic valve is closed, the medium enters the active cavity, presses the active part to move, and controls the guide ruler to move away from the machine body through the adjusting shaft;

[0112] S-3: after the adjustment is completed, the user releases the pressing body, and the partial electric conductor and the electric head are in contact, and enter the second mode, when the liquid inlet electromagnetic valve is closed and the liquid outlet electromagnetic valve is opened, the medium in the active cavity can be pressed by the active part under the action of the first reset spring, and is discharged from the liquid outlet one-way nozzle and the liquid outlet branch to reset the guide ruler.

[0113] In the embodiment, the heat dissipation step of the machine body comprises:

[0114] S-4: on the basis of step S-1, the turbine assembly and the receiving control body are selected to enter the second mode;

[0115] S-5: in the second mode, the driver drives the turbine to rotate, and the medium in the adjusting source is guided out and circulates in the liquid outlet branch, the liquid return branch and the adjusting source to complete the heat dissipation of the machine body.

[0116] In the use method of the embodiment, the cooling liquid can be guided out and into the receiving control body in the first mode, and the mode is the initial step of the use method of the embodiment, and the user can press the pressing body (that is, press the pressing body completely to make the circuit X and the circuit Y be powered on at the same time), so that the cooling liquid is first guided into the receiving control body, and the part of the cooling liquid is not enough to drive the active part to move.

[0117] Based on the above initial steps, and without the need to adjust the guide ruler, timely partial release of the pressing body, so that the circuit Y is powered off, so that the circuit X remains powered on, in this mode, the heat dissipation is carried out, and since part of the cooling liquid is sent into the receiving control body, it can dissipate heat inside the receiving control body, and ensure the integrity of heat dissipation;

[0118] And when the guide ruler position needs to be adjusted, immediately switch to the first mode, and when the cooling liquid is sent into the receiving control body again, the guide ruler can be immediately adjusted, achieving the timeliness of adjustment.

[0119] Reference Figures 1-5 The principle of the embodiment is:

[0120] In use, the original position of the receiving control body is adjusted by the limiting structure, so that the distance between the guide ruler and the machine body is suitable for the current planing work of the plate, after the adjustment is completed, the user controls the button to make the electric planer of the embodiment move on the wood, so as to complete the planing work;

[0121] When planing some irregular edge plates, for example, there are several convex positions on the edge, and after the position adjustment of the guide ruler is completed, the position of the guide ruler is relatively fixed, therefore, the existing method is to stop planing when passing through these positions, and then adjust the guide ruler again and then planing;

[0122] The method of the embodiment is that after the original position adjustment of the guide ruler is completed (i.e. after the position adjustment of the receiving control body by the limiting structure is completed), when the guide ruler passes through the convex position of the wood edge, it is not necessary to stop, the user needs to use the pressing body of the handle position to make the circuit X and the circuit Y powered on, and the inlet electromagnetic valve and the outlet electromagnetic valve are powered on, when the two are powered on, the inlet electromagnetic head valve makes the inlet branch open, and the outlet electromagnetic valve makes the outlet branch close, and when the circuit X is powered on to start the turbine, the cooling liquid in the adjustment source is sent into the movable cavity from the inlet branch, and the movable part is moved to press the first return spring, so as to drive the guide ruler away from the machine body, so that the guide ruler smoothly passes through the convex position of the wood edge, ensuring the continuous planing work and ensuring the efficiency of planing;

[0123] When the guide ruler passes the protruding part of the edge of the wood, the pressing body is released to de-energize circuit Y. When circuit Y is de-energized, the liquid inlet solenoid valve and the liquid outlet solenoid valve lose power and remain in normal state, that is, the liquid outlet branch and the liquid return branch are connected, the liquid inlet branch is closed, and the liquid outlet branch is opened. In this state, if circuit X is energized, the turbine can drive the coolant in the heat dissipation branch to flow to complete the heat dissipation work of the body and handle. After the liquid inlet solenoid valve and the liquid outlet solenoid valve are de-energized, the coolant in the moving chamber is squeezed out from the liquid outlet branch by the first return spring driving the moving part to return and enter the liquid return branch, and then the guide ruler returns to its original position.

[0124] In summary, in this embodiment, when planing the surface of a board with irregular edges, the position of the guide ruler can be adjusted in a timely manner so that the guide ruler can always fit against the edge of the board when planing any position on the board surface, thereby ensuring the efficiency of planing.

[0125] It should be noted that when circuit X is energized, the coolant in the regulating source is sent to the receiving control body. During the process of the coolant moving in the outlet branch, it can also dissipate heat from the body. Therefore, in this mode, the dual purpose of heat dissipation from the body and guide adjustment can be achieved. When the regulating components of this embodiment are not used, the user does not need to use the pressing body, and can simply de-energize both circuit X and circuit Y.

[0126] Example 2 differs from Example 1 in that...

[0127] like Figure 6 As shown, in this embodiment: the adjustment source 40 includes:

[0128] A medium cavity 400 is formed on the body 10 and has a liquid outlet 401 and a liquid return port 402;

[0129] The sealing cap 403 is detachably disposed at the opening of the medium cavity 400. In this embodiment, the sealing cap 403 can be detached from the medium cavity 400 by thread.

[0130] The sealing cover 403 is provided with a filter element structure 404 (a cylindrical shape formed by a filter screen), and a notch 405 corresponding to the return port 402 is provided on the filter element structure 404.

[0131] refer to Figure 6 The principle of this embodiment is:

[0132] The detachable sealing cover can realize replacement of the cooling liquid in the medium cavity. The liquid outlet of the embodiment is arranged at the bottom of the medium cavity, so that the impurity content of the cooling liquid entering the heat dissipation branch is reduced, and the cooling liquid discharged through the return liquid outlet directly passes through the filter core structure through the gap. Therefore, when the heat dissipation branch circulates, most of the impurities in the heat dissipation branch are controlled in the medium cavity, and the impurities can be concentratedly treated when the cooling liquid is maintained and replaced.

[0133] The above merely describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
