Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper-clad plate processing equipment, in particular to a conveying device for copper-clad plate processing and drying. BACKGROUND

[0002] Copper-clad plate (CCL) is the core substrate of printed circuit board (PCB), and its performance directly determines the insulation reliability, mechanical strength and environmental stability of PCB, and is widely used in consumer electronics, communication equipment, automotive electronics, aerospace and other fields. With the development of the electronic industry towards "high precision, thin, high frequency", higher requirements are put forward for the processing precision of copper-clad plate (such as resin curing uniformity and copper foil bonding force), and the drying process is a key link in the processing of copper-clad plate - through continuous conveying and accurate drying, the moisture after substrate pretreatment, the solvent in the resin after impregnation and the adsorbed water vapor before lamination are removed to avoid bubbles, delamination in subsequent lamination, or performance degradation after curing.

[0003] Taking the most widely used net belt type hot air circulation dryer as an example, the core design logic is that hot air is sprayed from the upper and lower air ducts of the net belt, and "double-sided clamping type drying" is achieved through the air permeability of the net belt. However, in the actual processing process, due to the inconsistent air volume of the upper and lower sides of the drying device when outputting hot air, the resin on the upper surface of the copper-clad plate quickly solidifies, the resin on the lower surface is not fully crosslinked due to solvent residue, and the shrinkage rate of the upper surface is small and the shrinkage rate of the lower surface is large during subsequent lamination, resulting in warping of the plate. At the same time, the copper-clad plate is easily offset to one side due to the influence of the upper air supply thrust, and edge burrs are generated by friction with the oven stop edge. In severe cases, it needs to be stopped and disassembled for cleaning, which affects the production efficiency. SUMMARY

[0004] To solve the above technical problems, the present application provides a conveying device for drying copper-clad plate processing, which comprises a support frame, a motor shaft rotatably connected to the inner wall of the support frame, a net belt conveyor belt sleeved on the outer wall of the motor shaft, and a hot air motor pump fixedly connected to the outer wall of the support frame. The shunt mechanism is fixedly connected to the inner wall of the hot air motor pump, and is used for uniformly shunting the hot air. The cleaning mechanism is fixedly connected to the outer wall of the shunt mechanism, and is used for concentrating and collecting the remaining impurities. The air outlet mechanism is fixedly connected to the inner wall of the shunt mechanism, and is used for adjusting the air outlet. The inner wall of the hot air motor pump is fixedly connected with a hot air conveying pipeline, the outer wall of the hot air conveying pipeline away from the hot air motor pump is fixedly connected with a three-way pipe, and the inner wall of the three-way pipe is fixedly connected with a ring limiting block.

[0005] In use, first, the device is placed in the desired appropriate position, the drive motor of the conveyor belt is turned on, so that the motor shaft of the drive motor starts to rotate, due to the rotation of the motor shaft, the mesh belt conveyor belt will move, in turn, drive the copper-clad plate on it to move, then start the hot air motor pump, so that the hot air motor pump starts to output hot air; Preferably, the shunt mechanism comprises: The outer wall of the conveying assembly is fixedly connected with the outer wall of the three-way pipe; The outer wall of the shunt assembly is fixedly connected with the inner wall of the three-way pipe.

[0006] Preferably, the cleaning mechanism comprises: The outer wall of the connecting assembly is fixedly connected with the inner wall of the shunt assembly; The outer wall of the cleaning assembly is fixedly connected with the inner wall of the connecting assembly.

[0007] Preferably, the air outlet mechanism comprises: The outer wall of the air outlet assembly is fixedly connected with the inner wall of the shunt assembly; The outer wall of the sliding assembly is slidingly connected with the inner wall of the air outlet assembly.

[0008] Preferably, the conveying assembly comprises a lower conveying channel fixedly connected with the outer wall of the three-way pipe, a sliding block slidingly connected with the inner wall of the three-way pipe, and a tapered block slidingly connected with the inner wall of the three-way pipe.

[0009] The hot air blown by the hot air motor pump reaches the three-way pipe through the hot air conveying pipeline. When the hot air does not reach the annular limiting block, the tapered block is located between the sliding block and the annular limiting block, and at the same time, the sliding block is located at the lowest end of the three-way pipe due to its own gravity. At this time, the annular limiting block, the tapered block and the sliding block are in close contact with each other. When the hot air reaches the annular limiting block, it rises along the surface of the annular limiting block. Due to the action of the hot air motor pump, the tapered block is subjected to a force, so that the tapered block is pushed away from the annular limiting block. At the same time, the movement of the tapered block drives the sliding block to move together. After the tapered block rises, the gap between the annular limiting block and the tapered block is opened, so that the hot air can enter the lower conveying channel and one end of the sliding block of the three-way pipe through the gap between the annular limiting block and the tapered block. At the same time, the movement of the tapered block and the sliding block makes the sliding block and the tapered block still in close contact with each other, so that the hot air at the end of the sliding block does not mix with the hot air in the lower conveying channel. At the same time, due to the shape of the tapered block, the air flow through the two sides is the same, so that the hot air output by the hot air motor pump is divided into two parts that are roughly equal. When the copper-clad plate is dried, the air flow at the upper and lower ends is roughly consistent, reducing the possibility that the copper-clad plate will be offset due to inconsistent air flow at the upper and lower ends; Preferably, the shunt assembly comprises an upper conveying pipe fixedly connected at the inner wall of the tee pipe, an upper shell fixedly connected at the outer wall of the upper conveying pipe, a lower conveying pipe fixedly connected at the inner wall of the lower conveying pipe, and a connecting pipe fixedly connected at the outer wall of the lower conveying pipe.

[0010] Preferably, the connecting assembly comprises a plurality of upper tuyeres fixedly connected at the inner wall of the shunt assembly, a lower shell fixedly connected at the outer wall of the connecting pipe, and a plurality of lower tuyeres fixedly connected at the inner wall of the lower shell.

[0011] Preferably, the cleaning assembly comprises two impurity outlets formed at the outer wall of the connecting pipe, two connecting shafts fixedly connected at the inner wall of the connecting pipe, a rotating plate rotatably connected at the outer wall of the two connecting shafts, and a plurality of torsional springs sleeved at the outer wall of the two connecting shafts. The plurality of torsional springs are respectively sleeved at the outer wall of the two connecting shafts in pairs, the outer wall of the torsional spring is fixedly connected with the inner wall of the rotating plate, and the outer wall of the end of the torsional spring away from the rotating plate is fixedly connected with the inner wall of the connecting pipe.

[0012] When the hot air passes through the lower conveying pipe and is conveyed to the connecting pipe by the lower conveying pipe, the two rotating plates will contact each other and the channel of the connecting pipe will be closed due to the action of the torsional spring before the hot air reaches the rotating plate. In the long-term use process, the materials in the copper-clad plate, such as glass fibers and glue debris, fall onto the surface of the rotating plate. When the hot air reaches the bottom of the rotating plate, the rotating plate will be subjected to a force under the action of the wind force, causing the rotating plate to rotate, so that the two rotating plates on the sides will be opened, allowing the hot air to pass through the connecting pipe. At the same time, the debris and impurities on the surface of the rotating plate will fall into the two impurity outlets on both sides as the rotating plate rotates, preventing the debris from accumulating inside the connecting pipe and causing blockage of the lower tuyere and other devices. In addition, the impurities in the impurity outlets can be cleaned regularly to maintain the good operation of the device. Preferably, the air outlet assembly comprises a connecting column fixedly connected with a plurality of center air outlets formed at the outer wall of the top of the air outlet cover, and a reset spring sleeved at the outer wall of the connecting column.

[0013] Preferably, the sliding assembly comprises a plurality of air outlet pipes slidably connected at the inner wall of the connecting column, a spring fixedly connected at the inner wall of the plurality of air outlet pipes, a movable pipe fixedly connected at the outer wall of the end of the spring away from the air outlet pipe, and a turbulence fan rotatably connected at the inner wall of the air outlet cover. When the hot air reaches the connecting column through the connecting pipe, the spoiler fan is driven to rotate under the action of the wind force, and part of the hot air is output through the central air outlet after passing through the spoiler fan, and the other part of the hot air reaches the plurality of air outlet pipes arranged at the connecting column, and under the action of the wind force, the air outlet pipes start to slide towards the lower shell, and at the same time, the wind force makes the movable pipe start to slide away from the inner wall of the air outlet pipe, and part of the wind force entering the air outlet pipe is output through the hole arranged in the movable pipe, and after the movable pipe slides, the remaining hot air is output through the hole arranged in the air outlet pipe, and in the case that the wind force fluctuates, the air outlet pipe moves with the fluctuation of the wind force, when the wind force increases, the air outlet pipe is closer to the lower shell, so that the distance between the air outlet pipe and the lower air outlet increases, thereby increasing the moving distance of the hot air, and more buffering time is provided, and the air outlet is more stable. The outer wall of the movable pipe is slidably connected with the inner wall of the air outlet pipe.

[0014] Under the action of the hot air, the movable pipe starts to slide, and under the limitation of the inner wall of the lower shell, the movable pipe can only expand to the surface of the lower shell, and the bottom of the lower shell is a slope, and the length of the slope is proportional to the length of the side of the lower shell, so that the length of the short side of the bottom of the lower shell is longer than that of the long side, thereby reducing the slope of the short side, and the movable pipe moves a distance longer than that of the long side, and the distance of the movable pipe extending out is similar to the length of the four sides of the inner wall of the lower shell, thereby making the long side obtain more wind, reducing the difference between the long side and the short side, and further making the air outlet more uniform.

[0015] The present application has the following advantages: (1) The present application is to solve the device in the up and down air is not consistent, resulting in the drying of copper-clad plate, may cause copper-clad plate position offset, and then make the drying effect is reduced, is provided with shunt mechanism, hot air blower pump blowing hot air will through hot air delivery pipeline to reach the tee pipe place, when the hot air does not reach the annular limiting block, the conical block is located between the sliding block and the annular limiting block, at the same time, the sliding block is located at the lowest end of the tee pipe under the influence of its own gravity, at this time, the annular limiting block, the conical block, the sliding block three are pasted together, when the hot air reaches the annular limiting block, it will rise along the surface of the annular limiting block, due to the action of the hot air blower pump, the conical block is subjected to force, and then the conical block will be pushed away from the annular limiting block, at the same time, the movement of the conical block will drive the sliding block to move together, and the conical block rises will make the gap between the annular limiting block and the conical block be opened, so that the hot air can enter the lower conveying channel and the one end of the sliding block of the tee pipe through the gap between the annular limiting block and the conical block, at the same time, the conical block and the sliding block move together, so that the sliding block and the conical block are still in close contact with each other at this time, so that the hot air at the end of the sliding block will not mix with the hot air in the lower conveying channel, at the same time, due to the shape of the conical block, the air flow through both sides is the same, so that the hot air output by the hot air blower pump is divided into two parts that are roughly equal, so that when drying the copper-clad plate, the air volume at the upper and lower ends is roughly the same, reducing the possibility that the copper-clad plate will be offset due to the inconsistent air volume of the upper and lower ends; (2) The present application is to solve the device in the long-term operation, the material in the copper-clad plate, such as glass fiber, gum debris, etc. will cause the device to be blocked, is provided with cleaning mechanism, when the hot air reaches the bottom of the rotating plate, under the action of the wind, the rotating plate will be subjected to force, so that the rotating plate rotates, so that the rotating plate on both sides will open, so that the connecting pipe can pass through the hot air, at the same time, the debris and impurities on the surface of the rotating plate will fall into the impurity outlet on both sides with the rotation of the rotating plate, so that the debris will not accumulate in the inside of the connecting pipe, causing the lower air outlet and other devices to be blocked, at the same time, the impurities in the impurity outlet are cleaned regularly, to maintain the good operation of the device; (3) The present application is to solve the problem of vortex flow caused by hot air in the pipeline, which makes the wind flow unstable, resulting in poor drying effect, and sets up the air outlet mechanism. When the hot air passes through the connecting pipe to the connecting column, under the action of wind force, the spoiler fan will rotate under the action of wind force, and after passing through the spoiler fan, part of the hot air will be output through the central air outlet, and the other part of the hot air will reach the air outlet pipe arranged at the connecting column. Under the action of wind force, the air outlet pipe will start to slide towards the lower shell, at the same time, the wind force will make the movable pipe start to slide away from the air outlet pipe at the inner wall of the air outlet pipe, and the part of the wind force entering the air outlet pipe will be output through the hole arranged in the movable pipe. After the movable pipe slides, the remaining hot air will be output through the hole arranged in the air outlet pipe. Through this mechanism, the spoiler fan and the shunt of the air outlet pipe make the air outlet more stable; (4) The present application utilizes the above-mentioned mechanism operation principle. When under the action of hot air, the movable pipe will start to slide, and under the limitation of the inner wall of the lower shell, the movable pipe can only expand to the surface of the lower shell. The bottom of the lower shell is a slope, and the length of the slope is proportional to the length of the side of the lower shell, so that the length of the short side of the slope is longer than the length of the long side of the slope, thereby making the slope of the short side lower and the limitation of the movable pipe smaller. The moving distance of the movable pipe with short side is longer than that with long side, and the distance of the movable pipe extending out is similar to the length of the four sides of the inner wall of the lower shell, thereby making the long side get more wind, reducing the difference between the long side and the short side, and further making the air outlet more uniform.

The cleaning mechanism 2 is fixedly connected to the inner wall of the shunt mechanism 1, and is used for collecting the remaining impurities; The air outlet mechanism 3 is fixedly connected to the inner wall of the shunt mechanism 1, and is used for adjusting the air outlet; The inner wall of the hot air motor pump 16 is fixedly connected with the hot air conveying pipeline 111, the outer wall of the hot air conveying pipeline 111 away from the hot air motor pump 16 is fixedly connected with the three-way pipe 112, and the inner wall of the three-way pipe 112 is fixedly connected with the annular limiting block 113.

[0021] In use, first, the device is placed in the required appropriate position, the drive motor of the conveyor belt is started, the motor shaft 14 of the drive motor starts to rotate, the mesh belt conveyor belt 15 is driven to move due to the rotation of the motor shaft 14, and the copper-clad plate on the mesh belt conveyor belt 15 is driven to move, then the hot air motor pump 16 is started, and the hot air motor pump 16 starts to output hot air; The shunt mechanism 1 comprises: The conveying assembly 11 is fixedly connected to the outer wall of the three-way pipe 112; The shunt assembly 12 is fixedly connected to the inner wall of the three-way pipe 112.

[0022] The cleaning mechanism 2 comprises: The connecting assembly 21 is fixedly connected to the inner wall of the shunt assembly 12; The cleaning assembly 22 is fixedly connected to the inner wall of the connecting assembly 21.

[0023] The air outlet mechanism 3 comprises: The air outlet assembly 31 is fixedly connected to the inner wall of the shunt assembly 12; The sliding assembly 32 is slidingly connected to the inner wall of the air outlet assembly 31.

[0024] The conveying assembly 11 comprises a lower conveying channel 114 fixedly connected to the outer wall of the three-way pipe 112, a sliding block 115 slidingly connected to the inner wall of the three-way pipe 112, and a tapered block 116 slidingly connected to the inner wall of the three-way pipe 112.

[0025] The hot air blown by the hot air motor pump 16 will reach the tee pipe 112 through the hot air delivery pipe 111. When the hot air has not reached the annular limiting block 113, the conical block 116 is located between the sliding block 115 and the annular limiting block 113. At the same time, the sliding block 115 is located at the lowest end of the tee pipe 112 due to its own weight. At this time, the annular limiting block 113, the conical block 116, and the sliding block 115 are in close contact. When the hot air reaches the annular limiting block 113, it will rise along the surface of the annular limiting block 113. Due to the action of the hot air motor pump 16, the conical block 116 is subjected to a force, which will push the conical block 116 away from the annular limiting block 113. At the same time, the movement of the conical block 116 will drive the sliding block 115 to move together. After the conical block 116 rises, it will...

At the same time, the conical block 116 and the sliding block 115 move together, so that the sliding block 115 and the conical block 116 are still in close contact with each other, so that the hot air at the end of the sliding block 115 will not mix with the hot air in the lower conveying channel 114. At the same time, due to the shape of the conical block 116, the airflow through both sides is the same, so that the hot air output by the hot air motor pump 16 is divided into two roughly equal parts, so that the airflow at the upper and lower ends is roughly the same when drying the copper-clad laminate, reducing the possibility of the copper-clad laminate shifting due to the inconsistent airflow at the upper and lower ends. The diversion assembly 12 includes an upper conveying pipe 121 fixedly connected to the inner wall of the three-way pipe 112, an upper outer shell 122 fixedly connected to the outer wall of the upper conveying pipe 121, a lower conveying pipe 123 fixedly connected to the inner wall of the lower conveying channel 114, and a connecting pipe 124 fixedly connected to the outer wall of the lower conveying pipe 123.

[0026] The connecting component 21 includes several upper air outlets 211 fixedly connected to the inner wall of the diversion component 12, a lower outer shell 212 fixedly connected to the outer wall of the connecting pipe 124, and several lower air outlets 213 fixedly connected to the inner wall of the lower outer shell 212.

[0027] The cleaning component 22 includes two outlets 221 on the outer walls of both sides of the connecting pipe 124, two connecting shafts 222 fixedly connected to the inner wall of the connecting pipe 124, a rotating plate 223 rotatably connected to the outer wall of the two connecting shafts 222, and several torsion springs 224 sleeved on the outer wall of the two connecting shafts 222. Several torsion springs 224 are respectively sleeved on the outer wall of two connecting shafts 222 in pairs. The outer wall of the torsion spring 224 is fixedly connected to the inner wall of the rotating plate 223, and the outer wall of the end of the torsion spring 224 away from the rotating plate 223 is fixedly connected to the inner wall of the connecting tube 124. When the hot air passes through the lower conveying channel 114, the lower conveying pipe 123 is conveyed to the connecting pipe 124, and does not reach the rotating plate 223, due to the action of the torsional spring 224, the two side rotating plates 223 will contact each other, so that the channel of the connecting pipe 124 is closed, at the same time, due to the fact that during long-term use, the materials in the copper-clad plate, such as glass fibers, glue debris, fall on the surface of the rotating plate 223, when the hot air reaches the bottom of the rotating plate 223, under the action of the wind force, the rotating plate 223 will be subjected to a force, so that the rotating plate 223 rotates, so that the two side rotating plates 223 are opened, so that the connecting pipe 124 can pass through the hot air, at the same time, the debris and impurities on the surface of the rotating plate 223 will fall into the two side impurity outlets 221 with the rotation of the rotating plate 223, so that the debris will not accumulate in the inside of the connecting pipe 124, causing the blockage of the lower air outlet 213 and other devices, at the same time, the impurities in the impurity outlet 221 are cleaned regularly, to maintain the good operation of the device; Example two, please refer to Figure 2 Figure 12 The application is a conveying device for drying copper-clad plate processing, based on example one, the air outlet assembly 31 comprises a connecting column 311 fixedly connected, a plurality of air outlet covers 312 are fixedly connected to the outer wall of the connecting column 311, a plurality of central air outlets 313 are formed in the top outer wall of the air outlet cover 312, and a reset spring 314 is sleeved on the outer wall of the connecting column 311.

[0028] The sliding assembly 32 comprises a plurality of air outlet pipes 321 slidingly connected to the inner wall of the connecting column 311, a plurality of springs 322 are fixedly connected to the inner wall of the air outlet pipes 321, a movable pipe 323 is fixedly connected to the outer wall of the far end of the spring 322 away from the air outlet pipe 321, and a turbulence fan 324 is rotationally connected to the inner wall of the air outlet cover 312. ​When the hot air reaches the connecting column 311 through the connecting pipe 124, the spoiler fan 324 will rotate under the action of the wind force, and part of the hot air will be output through the central air outlet 313 after passing through the spoiler fan 324, and the other part of the hot air will reach the air outlet pipes 321 arranged at the connecting column 311, which will start to slide towards the lower shell 212 under the action of the wind force, and the wind force will make the movable pipe 323 start to slide away from the inner wall of the air outlet pipe 321, and part of the wind entering the air outlet pipe 321 will be output through the hole arranged in the movable pipe 323, and after the movable pipe 323 slides, the remaining hot air will be output through the hole arranged in the air outlet pipe 321, and in the case of fluctuation of the wind force, the air outlet pipe 321 will move with the fluctuation of the wind force, when the wind force increases, the air outlet pipe 321 is closer to the lower shell 212, so that the distance between the air outlet pipe 321 and the lower air outlet 213 increases, thereby increasing the moving distance of the hot air, and more buffering time is provided, and the air outlet is more stable; The outer wall of the movable pipe 323 is slidably connected with the inner wall of the air outlet pipe 321.

[0029] Under the action of the hot air, the movable pipe 323 will start to slide, and under the limitation of the inner wall of the lower shell 212, the movable pipe 323 can only expand to the surface of the lower shell 212, and the bottom of the lower shell 212 is a slope, and the length of the slope is proportional to the length of the side of the lower shell 212, so that the length of the short side of the bottom of the lower shell 212 is longer than that of the long side, thereby making the slope of the short side smaller and the limitation of the movable pipe 323 smaller, and the moving distance of the movable pipe 323 in the short side is longer than that in the long side, and the distance of the movable pipe 323 extending out is similar to the length of the four sides of the inner wall of the lower shell 212, thereby making the long side obtain more wind, reducing the difference between the long side and the short side, and further making the air outlet more uniform.

[0030] One specific application of the embodiment is: when in use, first place the device in the desired position, start the drive motor of the conveyor belt, so that the motor shaft 14 of the drive motor starts to rotate, due to the rotation of the motor shaft 14, the mesh belt conveyor belt 15 will move, thereby moving the copper-clad plate thereon, then start the hot air motor pump 16, so that the hot air motor pump 16 starts to output hot air; The hot air blown by the hot air motor pump 16 will reach the three-way pipe 112 through the hot air conveying pipe 111, when the hot air does not reach the annular limiting block 113, the conical block 116 is located between the sliding block 115 and the annular limiting block 113, at the same time, the sliding block 115 is located at the lowest end of the three-way pipe 112 under the influence of its own gravity, at this time, the annular limiting block 113, the conical block 116 and the sliding block 115 are attached together, when the hot air reaches the annular limiting block 113, it will rise along the surface of the annular limiting block 113, due to the action of the hot air motor pump 16, the conical block 116 is subjected to a force, thereby the conical block 116 will be pushed away from the annular limiting block 113, at the same time, the movement of the conical block 116 will drive the sliding block 115 to move together, and the rising of the conical block 116 will open the gap between the annular limiting block 113 and the conical block 116, so that the hot air can enter the lower conveying channel 114 and one end of the sliding block 115 of the three-way pipe 112 through the gap between the annular limiting block 113 and the conical block 116, at the same time, the conical block 116 moves together with the sliding block 115, so that the sliding block 115 and the conical block 116 are still in close contact with each other at this time, so that the hot air at the end of the sliding block 115 will not mix with the hot air in the lower conveying channel 114, at the same time, due to the shape of the conical block 116, the air flow through both sides is the same, so that the hot air output by the hot air motor pump 16 is divided into two parts that are almost equal, so that the air volume at the upper and lower ends is roughly consistent when drying the copper-clad plate, reducing the possibility that the copper-clad plate will be offset due to inconsistent air volume at the upper and lower ends; When the hot air passes through the lower conveying channel 114 and is conveyed to the connecting pipe 124 by the lower conveying pipe 123, and does not reach the rotating plate 223, due to the action of the torsional spring 224, the two rotating plates 223 will contact each other, so that the channel of the connecting pipe 124 is closed, at the same time, due to the fact that materials such as glass fibers and glue debris in the copper-clad plate fall onto the surface of the rotating plate 223 during long-term use, when the hot air reaches the bottom of the rotating plate 223, the rotating plate 223 will be subjected to a force under the action of the wind, so that the rotating plate 223 rotates, thereby the two rotating plates 223 will be opened, so that the connecting pipe 124 can pass through the hot air, at the same time, the debris and impurities on the surface of the rotating plate 223 will fall into the two impurity outlets 221 with the rotation of the rotating plate 223, so that the debris will not accumulate in the inside of the connecting pipe 124, causing blockage of the lower air outlet 213 and other devices, at the same time, the impurities at the impurity outlets 221 are cleaned regularly to maintain good operation of the device; When the hot air reaches the connecting column 311 through the connecting pipe 124, the spoiler fan 324 is driven to rotate under the action of the wind force, and part of the hot air passes through the central air outlet 313 after passing through the spoiler fan 324, and the other part of the hot air reaches the air outlet pipe 321 arranged at the connecting column 311, and the air outlet pipe 321 starts to slide to the lower shell 212 under the action of the wind force, and the wind force drives the movable pipe 323 to start to slide away from the inner wall of the air outlet pipe 321, and part of the wind force entering the air outlet pipe 321 is output through the hole arranged in the movable pipe 323, and after the movable pipe 323 slides, the remaining hot air is output through the hole arranged in the air outlet pipe 321, and in the case of fluctuation of the wind force, the air outlet pipe 321 moves with the fluctuation of the wind force, when the wind force increases, the air outlet pipe 321 is closer to the lower shell 212, so that the distance between the air outlet pipe 321 and the lower air outlet 213 increases, thereby increasing the moving distance of the hot air, and more buffering time is provided, and the air outlet is more stable. Under the action of the hot air, the movable pipe 323 starts to slide, and under the limitation of the inner wall of the lower shell 212, the movable pipe 323 can only expand to the surface of the lower shell 212, and the bottom of the lower shell 212 is a slope, and the length of the slope is proportional to the length of the side of the lower shell 212, so that the length of the short side of the bottom of the lower shell 212 is longer than that of the long side, thereby reducing the difference between the long side and the short side, and further making the air outlet more uniform.
