Fig. 5 is an exploded view of an electric planer according to an embodiment of the present application, fig. 6 is a view illustrating a structure of a rotating handle in the electric planer according to the embodiment of the present application, and fig. 7 is a view illustrating a structure of a first spring in the electric planer according to the embodiment of the present application.

In the electric planer of the related art, the static bottom plate, the planer tool assembly and the movable bottom plate are generally arranged at the bottom of the machine body in parallel in sequence, the machine body is further provided with a knob, one end of the knob is connected with the movable bottom plate and drives the movable bottom plate to lift relative to the machine body when rotating, and the exposed size of the planer tool assembly relative to the movable bottom plate can be adjusted so as to adjust the planing depth of the planer tool assembly. However, when the operator rotates the knob, the knob rotates smoothly, the rotation amount of the knob is judged by looking at the eyes completely, the condition that the rotation amount is too large or too small often occurs, the knob needs to be repeatedly rotated at this time, and the operation process is time-consuming, labor-consuming and inconvenient.

In view of this, referring to fig. 5, 6 and 7, in the electric planer 100 according to the embodiment of the present application, the adjusting assembly 30 includes: a rotation handle 33, which is provided on the body 10 and connected to the movable bottom plate 50, the rotation handle 33 being configured to be rotatable with respect to the body 10 and to drive the movable bottom plate 50 to move with respect to the body 10 in a direction perpendicular to the movable bottom plate 50; the first end surface of the rotating handle 33 along the axial direction thereof is provided with a plurality of first grooves 331 which are arranged at intervals along the circumferential direction of the rotating handle 33; the surface of the machine body 10 opposite to the first end surface is provided with a containing hole 332, the first spring 31 is arranged in the containing hole 332, and one end, close to the notch of the containing hole 332, is provided with a bearing part 34; and an abutting piece 35 which is provided on the carrying portion 34 and can sequentially abut against each first groove 331 under the action of a spring when the rotation handle 33 rotates; the inner diameter of the first spring 31 is larger than the outer dimensions of the bearing 34 and the abutment 35 so that the abutment 35 retracts inside the first spring 31 when passing the portion between adjacent first grooves 331.

In the above-mentioned scheme, by providing the first springs 31 and the abutting pieces 35, and arranging the first grooves 331 on the rotating handle 33 at intervals in the circumferential direction, on the one hand, when the rotating handle 33 rotates, the abutting pieces 35 abut against each first groove 331 in turn under the elastic force of the springs, in other words, the abutting pieces 35 continuously repeat the actions of abutting against the first grooves 331 and the portions between the adjacent two first grooves 331, and when abutting against the first grooves 331 and the portions between the adjacent two first grooves 331, the hand feeling brought to the operator is different, and when the rotating handle 33 rotates, the alternating change in the hand feeling can be used for helping the operator to judge the rotation amount, so that the problem that the rotating handle 33 needs to be repeatedly adjusted is avoided, and the operation process is simplified. In addition, the contact member 35 is in contact with the first grooves 331 and the portions between the adjacent first grooves 331, and forms a resistance feedback to the rotation of the rotation handle 33, thereby improving the operation experience of the operator.

On the other hand, the first spring 31 is disposed in the accommodating hole 332, and the inner diameter of the first spring 31 is larger than the outer dimensions of the bearing portion 34 and the abutment member 35, so that the abutment member 35 at least partially retracts into the main body section when passing through the portion between the adjacent first grooves 331, and thus, even if the abutment member 35 has a tendency to move along tangential direction due to friction contact with the first end surface, the abutment member will not separate from the first spring 31 due to the blocking of the first spring 31 and the wall of the accommodating hole 332. This makes it possible to stabilize the movement of the abutment 35 in the abutment direction, and the abutment 35 does not shake left and right with the first spring 31.

Wherein, the first end surface of the rotation handle 33 in the axial direction thereof is configured with a plurality of first grooves 331 arranged at intervals in the circumferential direction of the rotation handle 33, meaning that the plurality of first grooves 331 are arranged at intervals from each other in the circumferential direction. In particular, the center of any one of the first grooves 331 is located on a circle with the intersection point of the axis of the rotating handle 33 and the first end surface as a center and the radius r, where the intersection point of the axis of the rotating handle 33 and the first end surface is r. When the rotating handle 33 rotates, the position of the abutting piece 35 is unchanged, and the rotating handle 33 does not move relative to the abutting piece 35 in the X direction and the Y direction during rotation, so that the rotating handle 33 rotates and rotates relative to the abutting piece 35 around the axial direction of the rotating handle, and therefore when the rotating handle 33 rotates, each first groove 331 moves relative to the abutting piece 35 along the track of the circumference. That is, when the rotating handle 33 rotates, the abutting piece 35 can always abut against any one of the first grooves 331 on the circumference.

In addition, the first spring 31 is disposed in the accommodating hole 332, and the first spring 31 may be disposed in the accommodating hole 332 and not connected to the accommodating hole 332, and the sum of the lengths of the first spring 31 and the bearing portion 34 is slightly smaller than the depth of the accommodating hole 332, so that the abutment member 35 is carried on the bearing portion 34, and at least a portion of the abutment member 35 is disposed in the accommodating hole 332, and when the rotating handle 33 rotates, no matter the abutment member 35 is disposed in the first groove 331 or a portion disposed between the two first grooves 331, the portion is not separated from the bearing portion 34 due to the protection of the edge of the opening of the accommodating hole 332. Of course, the first spring 31 may be detachably connected in the receiving hole 332.

In order to further improve the stability of the abutment 35 during abutment, it is conceivable to match the inner diameter of the receiving hole 332 with the outer diameter of the first spring 31, where the matching means that the inner diameter of the receiving hole 332 is substantially the same as the outer diameter of the first spring 31, or that the inner diameter of the receiving hole 332 is slightly larger than the outer diameter of the first spring 31, as long as the wall of the receiving hole 332 can restrict the shake of the first spring 31.

In the embodiment of the present application, with continued reference to fig. 7, the bearing portion 34 is configured as the second spring 32, and the outer diameter of the second spring 32 is smaller than the inner diameter of the first spring 31. The second spring 32 can thus also provide an elastic force for the abutment action of the abutment 35, and in addition, the outer diameter of the second spring 32 is smaller than the inner diameter of the first spring 31, facilitating the retraction of the second spring 32 inside the first spring 31.

In addition, the abutment 35 may be configured as a ball, the diameter of the abutment 35 being larger than the inner diameter of the second spring 32, and both the outer diameters of the abutment 35 and the second spring 32 being smaller than the inner diameter of the first spring 31, for example. Since the diameter of the abutment 35 is larger than the inner diameter of the second spring 32, a part of the surface of the ball can be supported in the second spring 32, with a large part exposed outside the second spring 32. Since the outer diameter of the abutment 35 and the outer diameter of the second spring 32 are smaller than the inner diameter of the first spring 31, the abutment 35 and the second spring 32 can retract to the inner side of the first spring 31 when the balls are pressed when the balls pass through the adjacent two first grooves 331.

In the embodiment of the present application, referring to fig. 1 and 5, the rotating handle 33 may be located at the top of the machine body 10, the movable bottom plate 50 includes a bottom plate body 51 and a connecting member 52 connected to the bottom plate body 51, and one end of the connecting member 52 away from the bottom plate body 51 penetrates through the machine body 10 and is screwed to the rotating handle 33; when the rotating handle 33 rotates relative to the machine body 10, the connecting piece 52 drives the base plate body 51 to move along the axial direction of the connecting piece 52, that is, the direction perpendicular to the movable base plate 50.

Specifically, the first end surface of the rotating handle 33 may abut against the machine body 10, so that when the rotating handle 33 rotates, since the rotating handle 33 is kept stationary relative to the machine body 10 in both the X direction and the Y direction, the connecting piece 52 in threaded engagement with the rotating handle 33 will move axially along itself, and drive the movable bottom plate 50 to move in a direction perpendicular to itself, thereby adjusting the size of the planer tool assembly 80 exposing the movable bottom plate 50. Of course, in the process of rotating the rotating handle 33, the abutting piece 35 continuously repeats the process of abutting the first grooves 331 and abutting the portions between the adjacent two first grooves 331 under the action of the elastic forces of the first springs 31 and the second springs 32, so that an operator can judge the rotation amount according to the hand feeling assistance, reduce the times of repeated rotation, and simplify the adjustment process.

With continued reference to fig. 6 in an embodiment of the present application, the rotating handle 33 may include a knob 333 and a rotating disc 334. Specifically, the knob 333 is screwed to an end of the connecting member 52 away from the base plate body 51, the rotating disc 334 is disposed on an outer peripheral surface of the knob 333, and scale marks (not shown) are configured on a surface of the rotating disc 334 facing the machine body 10 to form the first end surface, and an outer peripheral surface having the surface opposite to the first end surface is configured with the scale marks. This allows the amount of rotation of the rotation handle 33 to be quantitatively expressed, which is convenient for the operator to obtain the amount of rotation in real time.

Since the static base plate 40 and the heat dissipation box 61 are respectively located outside the machine body 10 and inside the machine body 10, a first notch 1011 is formed on the machine body 10 for the static base plate 40 to contact with the heat dissipation box 61, and in specific implementation, the static base plate 40 is provided with a first protruding portion 41, and the first protruding portion 41 penetrates through the first notch 1011 and abuts against the heat dissipation box 61. Alternatively, the heat dissipation case 61 may be provided with a second protruding portion, and the second protruding portion penetrates through the first notch 1011 and abuts against the static base plate 40. Or the static bottom plate 40 may be provided with a first protruding portion 41, and the heat dissipation box 61 may be provided with a second protruding portion at a position corresponding to the first protruding portion 41, and the contact between the static bottom plate 40 and the heat dissipation box 61 is achieved by the mutual abutting of the first protruding portion 41 and the second protruding portion.

On the other hand, in order to make the heat dissipation case 61 and the heating element on the control circuit board 62 better contact, the surface of the heat dissipation case 61 facing the control circuit board 62 may be further provided with a third protrusion 611, and the third protrusion 611 abuts against the heating element.

Referring to fig. 10 and 11, in the electric planer 100 according to the embodiment of the present application, in order to sequentially discharge the wood chips formed by planing of the planing tool assembly 80, it is considered to provide a passage for chip removal in the machine body 10.

In particular, the machine body 10 may be internally configured with a wood chip passage 82, an air supply chamber 83 and a planing tool chamber 81; at least two chip outlets 823 are formed in the chip channel 82, and an air inlet 825 for air flow of the air supply cavity 83 to enter and a chip inlet 824 for chip in the planing tool cavity 81 to enter are formed in the chip channel 82.

In the above scheme, the air inlet 825 formed in the wood chip channel 82 may be communicated with the air supply cavity 83, so that the air flow generated in the air supply cavity 83 may enter the wood chip channel 82 from the air inlet 825, the wood chip channel 82 is further provided with the chip inlet 824, the chip inlet 824 may be communicated with the planing tool cavity 81, and thus the wood chips generated by planing the planing tool assembly 80 in the planing tool cavity 81 may enter the wood chip channel 82 through the chip inlet 824, in addition, at least two chip outlets 823 are further formed in the wood chip channel 82, and after the wood chips entering the wood chip channel 82 are mixed with the air flow, the wood chips may fly out of the wood chip channel 82 through the chip outlets 823 which are not blocked under the driving of the air flow, so that the orderly discharge of the wood chips is realized.

Referring to fig. 11, 12, and 13, the electric planer 100 further includes a plug 70, and the plug 70 includes:

a cover 71 which covers the chip outlet 823 and is positioned outside the chip outlet 823;

the chip blocking portion 72 is integrally formed with the cover portion 71, and is blocked inside the chip outlet 823, and at least part of the chip blocking portion 72 is blocked at the air inlet 825.

It will be appreciated that at least one chip outlet 823 of at least two chip outlets 823 of the chip passage 82 is not blocked by the plug 70 for chip discharge when the electric planer 100 is in operation.

In the embodiment of the present application, two chip outlets 823 are provided in the chip channel 82, and when the electric planer 100 works, an example is described in which one chip outlet 823 is blocked by the plug 70, and the number of the chip outlets 823 and the number of the blocked chip outlets 823 are similar to each other, and are not described herein again.

In the above-described embodiment, with continued reference to fig. 11, the outer peripheral dimension of the lid portion 71 is set to be slightly larger than the inner peripheral dimension of the chip outlet 823, so that the chip outlet 823 can be blocked when the lid portion 71 is covered on the chip outlet 823. When the plug 70 is attached to the single chip outlet 823, the chip blocking portion 72 is blocked in the chip passage 82, and at least part of the chip blocking portion 72 is blocked in the air inlet 825. In this way, the chips entering the chip passage 82 from the chip inlet 824 communicating with the planing tool cavity 81 are shielded by the chip blocking portion 72 from entering the air supply cavity 83 from the air inlet 825, thereby avoiding damage to the fan 832 and the like.

It will be appreciated that the cover portion 71 and the chip blocking portion 72 are integrally formed, which can reduce manufacturing costs.

Referring to fig. 11, 12, and 13, the chip blocking portion 72 includes an integrally formed blocking portion 721 and a chip blocking plate 722, and the chip blocking plate 722 extends from the blocking portion 721 in a direction away from the blocking portion 721, for example, in the Y direction, and is configured to block the air inlet 825. Thus, the chip baffle 722 can divide the chip passage 82 into two first spaces 821 and second spaces 822 spaced apart from each other, so as to effectively prevent chips from entering the air supply chamber 83 through the air inlet 825. The space near the air inlet 825 is a first space 821, and the space near the chip inlet 824 is a second space 822.

Further, a notch 723 is provided at the boundary between the chip blocking plate 722 and the blocking portion 721, and when the chip blocking plate 722 is blocked by the gas inlet 825, the gas at the gas inlet 825 flows into the space defined by the inner wall of the chip passage 82 and the chip blocking plate 722, that is, the second space 822 through the notch 723. Referring specifically to fig. 11, the solid arrows indicate the flow paths of the air flow, the air flow generated in the air supply chamber 83 enters the first space 821 through the air inlet 825, and due to the shielding of the chip blocking plate 722, the air flow flows along the plate surface direction of the chip blocking plate 722, reaches the notch 723, enters the second space 822, and drives the chips generated in the planing tool chamber 81 and entering the second space 822 through the chip inlet 824 to flow out of the chip channel 82 through the chip outlet 823. The flow path of the chips is indicated by the broken-line arrows, and the chips in the planing tool cavity 81 enter the second space 822 of the chip passage 82 through the chip inlet 824, and flow out of the chip passage 82 from the unplugged chip outlet 823 by the air flow flowing in the second space 822.

In the embodiment of the present application, with continued reference to fig. 12 and 13, the cover portion 71 and the chip blocking portion 72 are integrally formed as described above. In order to make the wall thickness of the plug 70 as uniform as possible, it is conceivable to provide at least one hollow 7211 in the plug portion 721.

For example, the plug 70 may be integrally formed by injection molding. It will be appreciated that solid block structures shrink after injection molding is completed and care should be taken to avoid this during structural design. In addition, as the hollow portion 7211 is disposed on the plugging portion 721 as described above, the portion with the hollow structure has a mold support during injection molding, so that the deformation of the portion with the hollow structure is smaller during molding, which is beneficial to improving the strength and quality of the product.

In embodiments of the application, two chip outlets 823 may be located at opposite ends of the chip channel 82, with both the air inlet 825 and the chip inlet 824 being located between opposite ends of the chip channel 82.

Fig. 14a is a schematic view of another structure of a plug in an electric planer according to an embodiment of the present application, and fig. 14b is a schematic view of another structure of a plug in an electric planer according to an embodiment of the present application.

Thus, when the plug 70 is mounted on either one of the two chip outlets 823, chips entering from the chip inlet 824 can enter the chip outlet 725 and be discharged from the electric planer 100 through the chip outlet 823 communicating with the chip outlet 725. While the other diverting opening 726 faces the inner wall of the chip channel 82 and has no influence on the chip discharge process. When the plug is removed from the chip outlet 823 on one side and plugged into the chip outlet 823 on the other side, the other reversing port 76 can be communicated with the chip inlet 824 without rotating the plug along the circumferential direction of the plug, and the reversing port 73 can be matched with the chip outlet 725 to finish chip discharging.

The plug 70 shown in fig. 14b is similar in structure to fig. 14b, except that the specific structure of the hollowed-out portion 7211 is slightly changed.

The air supply cavity 83 has a cover 831 that can be opened and closed, and a fan 832 is further disposed in the air supply cavity 83, and the fan 832 is connected to the driving assembly and rotates under the driving of the driving assembly to generate a flowing air flow in the air supply cavity 83.

Referring to fig. 16, in a cross section of the air supply chamber 83 along the axial direction of the fan 832, a portion of the chamber wall section near the air outlet end 833 is constructed in an involute shape.

In the scheme that the air supply cavity is in a circular shape in the prior art, centrifugal forces at all positions of the outer edge of the fan are equal, and if wood dust enters the air supply cavity, the wood dust is difficult to throw out. In the embodiment of the present application, in the cross section of the air supply cavity 83 along the axial direction of the fan 832, the part of the cavity wall section near the air outlet end 833 is configured in an involute shape, and the centrifugal force increases with the increase of the radius due to the part of the cavity wall near the air outlet end 833, so that the wood chips inadvertently entering the air supply cavity 83 are thrown out at the air outlet end 833.
