[0002] Woodworking planing tool refers to the tool used in woodworking process, mainly used for planing, planing, planing or thinning wood, the main function of planing tool is to cut the wood surface through the cutter, to achieve the effect of flatness and smoothness. With the development of technology, now usually use electric woodworking planer instead of hand planing, and in the process of planing, a large amount of wood chips will be produced, in the prior art, wood chips are mainly collected through external dust collector, its disadvantage is that the discharge channel is easily blocked by coarse wood chips, the operator needs to collect wood chips through external dust collector, if external dust collector is not used, the discharge cover will be blocked and cannot be discharged, if the discharge cover is removed to discharge, wood chips will fly and the machine table is not easy to clean after planing, which still needs to be treated with air gun and other tools.

[0003] The patent with publication number CN220807831U discloses a chip removal mechanism of a planer, which comprises a head assembly, a motor, a cutter shaft mechanism and a chip removal cover arranged in the head assembly; the motor drives the cutter shaft mechanism to rotate through a transmission mechanism; the chip removal cover comprises a chip removal inlet and a chip removal outlet, the chip removal inlet is close to the cutter shaft mechanism, and a fan blade is arranged on the motor or the transmission mechanism; an air inlet is formed in the chip removal cover and close to the fan blade; when the fan blade rotates, the airflow generated by the fan blade enters the chip removal cover from the air inlet to guide the waste chips at the chip removal inlet to the chip removal outlet.

[0004] The above-mentioned scheme effectively utilizes the power of the planer during normal operation to remove chips, and realizes the discharge of wood chips, but the airflow generated by the rotation of the fan blade directly enters the large space of the chip removal inlet from the air inlet, at this time the airflow easily flows without direction, the utilization rate is not high, so that when the airflow flows to the air inlet, a large part of the energy has been consumed, and with the continuous flow of the airflow and the obstruction of the wood chips, the airflow pressure will continue to decrease, so that when there are many wood chips and the process of discharging outward, the speed may become smaller and smaller to adhere and stay in the chip removal cover, thereby causing the wood chips to slowly accumulate in the chip removal cover. SUMMARY

[0005] The utility model discloses a kind of woodworking planing tools with the function of blowing shavings, by utilizing the negative pressure of heat dissipation fan blade of its own motor, wood chips are discharged outward, and pipeline connection is set, ensure that airflow pressure is relatively average and enough to drive wood chips to flow in the process of discharging outward, avoid the process of discharging outward of wood chips, speed slows down and accumulates.

[0006] To solve the above problems, the present invention adopts the following solution:

[0007] A woodworking planing tool with a chip-blowing function includes a hanger, a planing assembly, a motor unit, a fan hood, a dust exhaust hood, and a pipe assembly. The planing assembly is installed below the hanger. The motor unit is connected to the hanger via the fan hood. The motor unit has a cooling fan blade inside. The fan hood has a mounting groove corresponding to the cooling fan blade. The pipe assembly includes a main pipe connected to the mounting groove and multiple branch pipes connected to the main pipe. The branch pipes are connected to different parts of the dust exhaust hood. The dust exhaust hood includes a dust inlet connected to the chip-generating part of the planing assembly and an exhaust port connected to the dust inlet to allow the chip to be discharged.

[0008] In the above scheme, the motor unit provides power to the planing component, driving it to plan the wood workpiece. To achieve heat dissipation and ensure the performance and service life of the motor unit, a cooling fan is usually installed. The airflow generated by the rotation of the cooling fan blows through the fan shroud to the main pipe, and the main pipe then flows through branch pipes to different parts of the dust exhaust hood. Therefore, on the one hand, the utilization rate of the airflow generated by the cooling fan is improved, and on the other hand, it is ensured that the dust inlet can not only adsorb wood chips, but also that the adsorption force is relatively uniform in all places. This avoids the situation where the airflow decreases and the speed decreases during the continuous discharge of wood chips, which may cause wood chips to accumulate in the dust exhaust hood when there are a lot of them.

[0009] Preferably, the hood is also provided with an exhaust channel connected to the mounting slot. The exhaust channel is connected to the main pipe and has multiple air outlets. The multiple air outlets are all located at the dust inlet of the dust hood and are arranged along the length of the dust inlet.

[0015] Preferably, there are two branch pipes, which are respectively connected to the side wall and the top wall of the dust hood.

[0016] The branch pipes are arranged at the side and the upper side of the dust exhaust cover respectively, so that the airflow entering the dust exhaust cover has different flow directions and is located at different positions, further ensures that the adsorption force received by the wood chips during the discharging process is more uniform, and ensures that the wood chips flow out of the dust exhaust cover smoothly and are not accumulated.

[0020] As preferred, the dust outlet cover is detachably connected with the dust exhaust cover.

[0021] In the above arrangement, the dust outlet cover is detachable with the dust exhaust cover, so that the wood chips adhered to the inner walls of the dust outlet cover and the dust exhaust cover can be easily cleaned.

[0022] As preferred, the heat dissipation fan blade is covered in the motor set and the mounting groove.

[0023] In the above arrangement, the heat dissipation fan blade is covered in the motor set and the mounting groove, so that the airflow generated by the heat dissipation fan blade passes through the main pipeline and the air outlet into the dust exhaust cover, ensuring that the generated airflow is not wasted and is used to discharge the wood chips out of the dust exhaust cover.

[0024] As preferred, the mounting bracket is further provided, the hanging bracket and the planing assembly are mounted on the mounting bracket, and the mounting bracket is further provided with a mounting plate for placing the wood piece to be planed, the mounting plate is located below the planing assembly, and both ends of the mounting plate exceed the planing assembly.

[0025] The mounting bracket and the mounting plate are arranged to make the woodworking planing tool structure more complete and ensure that the wood piece to be planed is planed smoothly.

[0026] The woodworking planing tool has the following beneficial effects:

[0027] The woodworking planing tool utilizes the heat dissipation fan blade of the motor set as a power source for discharging the wood chips, avoids adding other power devices, saves energy, and reduces production cost.

[0028] When the heat dissipation fan blade rotates to dissipate heat, the airflow generated by the rotation is blown to the main pipeline through the fan cover on one hand, and the main pipeline flows to different parts of the dust exhaust cover through the branch pipeline, on the other hand, directly through the plurality of air outlets to the different parts of the dust exhaust cover, so on one hand, the utilization rate of the airflow generated by the heat dissipation fan blade is improved, on the other hand, the airflow in the dust exhaust cover is ensured to be relatively average in size and can generate sufficient air pressure difference to continuously and smoothly discharge the wood chips, so as to prevent the wood chips from being blocked during the chip removal process.

The branch pipes 62 communicate with different parts of the dust exhaust cover 50. The dust exhaust cover 50 comprises a dust inlet 51 communicating with the part of the planing assembly where wood chips are generated and a dust outlet 52 communicating with the dust inlet 51 to discharge the wood chips.

[0038] In order to facilitate the planing of the wood piece to be processed, the mounting bracket 10 is also provided with a mounting plate 80 for placing the wood piece to be planed. The mounting plate 80 is located below the planing assembly, and both ends of the mounting plate 80 exceed the planing assembly.

[0039] This scheme takes advantage of the fact that the motor set 30 needs to be cooled, effectively uses the cooling fan blade 31 for cooling, generates negative pressure through the airflow generated by the rotation of the cooling fan blade 31, and discharges the wood chips. The airflow generated by the pipe assembly 60 flows to different parts of the dust exhaust cover 50, ensuring that the airflow in the dust exhaust cover 50 is relatively uniform in size, so that the dust inlet 51 not only can adsorb wood chips, but also the adsorption force is relatively uniform, avoiding the decrease of airflow speed during the continuous discharge of wood chips, which may cause the accumulation of wood chips in the dust exhaust cover 50 when there are many wood chips.

[0040] To further ensure the airflow average of the dust exhaust hood 50 and increase the airflow, ensure that the wood chips can be smoothly and continuously discharged. The air cover 40 is also provided with an exhaust passage 42 communicated with the installation groove 41, the exhaust passage 42 is communicated with the main pipeline 61, and the exhaust passage 42 is also communicated with a plurality of air outlets 43, the plurality of air outlets 43 are located at the dust inlet 51 of the dust exhaust hood 50, and the plurality of air outlets 43 are arranged along the length direction of the dust inlet 51, so that the airflow from the air outlet 43 is provided to the wider dust inlet 51 every small distance, to ensure that the overall airflow of the dust inlet 51 is sufficient and average, in the embodiment, the air outlet 43 is provided with four.

[0041] To facilitate the production and manufacture of the pipeline assembly 60, the main pipeline 61 and the branch pipeline 62 can be detachably connected. The main pipeline 61 and the branch pipeline 62 are communicated through the multi-way pipe 63;

[0042] To further facilitate the communication between the main pipeline 61 and the branch pipeline 62, a connecting pipeline 64 can also be detachably connected between the main pipeline 61 and the multi-way pipe 63, so that the distance between the main pipeline 61 and the branch pipeline 62 can be adjusted, and the applicability of the pipeline assembly 60 is higher.

[0047] To efficiently utilize the airflow generated by the rotation of the heat dissipation fan blade 31. The heat dissipation fan blade 31 is covered in the motor set 30 and the installation groove 41.

[0048] The working process of the embodiment is as follows:

[0049] The wood piece to be planed is placed on the setting plate 80, and the motor set 30 is started, and the wood piece is pushed slowly to make the planing assembly plan the surface of the wood piece. After the motor set 30 is started, the cooling fan blade 31 rotates to generate air flow. The air flow blows to the main pipeline 61 through the fan cover 40, and the main pipeline 61 flows to different parts of the dust exhaust cover 50 through the branch pipeline 62. On the other hand, the air flow blows to different parts of the dust exhaust cover 50 directly through the exhaust passage 42 and the plurality of air outlets 43 of the fan cover 40. Therefore, on the one hand, the utilization rate of the air flow generated by the cooling fan blade 31 is improved, and on the other hand, the air flow in the dust exhaust cover 50 is relatively average, and sufficient air pressure difference can be generated to make the wood chips continuously and smoothly discharged outward.
