Description

Technical Field

[0001] The present application relates to the technical field of process fans, and in particular to a moisture-proof process fan. Background Art

[0002] The ribs of existing fans are mostly made of bamboo. For example, the application with publication number CN105266313B discloses a process for making ribs of a fan, and the steps of the method are as follows: obtain a rib antiseptic solution; take bamboo or wood, and obtain a rib blank by flat-polishing, pressure-cutting or double-sided cutting, and put the rib into the rib antiseptic solution; take out the bamboo rib, spray it with clean water, remove the attachments on the rib, and air-dry it; spray the air-dried rib with hydrogen peroxide, put it in a drying room for drying until the surface of the rib is dry; use a cutting machine to evenly cut the ribs in step e to obtain a number of rib rods. The rib rods obtained in step f are connected by pins or threading lines to form ribs of a folding fan. The ribs made by the process of the present invention are not only stable in structure, but also beautiful in appearance. The ribs of the present invention can be used for round fans and folding fans, etc. It can be seen that when the existing folding fans are in use, the ribs are hinged by pins, so that the fans will have the following problems: First, after the fan has been used for a long time, the pins are worn out, resulting in increased mobility between the fan ribs, which makes it easy for the folded fan to be accidentally opened by external force when the user needs to fold it. Secondly, when the fan is accidentally opened when folding, the contact area between the entire fan and the air increases, making it easy for the fan to be affected by moisture in the air and cause mold spots or other stains that affect the appearance to appear on the fan surface or fan ribs.

[0003] Therefore, the present invention proposes a moisture-proof process fan to improve this problem. Summary of the invention

[0004] The purpose of this application is to solve the problems in the above-mentioned background technology, and this application provides a moisture-proof process fan.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A moisture-proof technical fan, comprising: There are two large fan ribs, which are hinged to each other, and the fan surface and the small fan ribs are installed between the large fan ribs. The large fan ribs are provided with a receiving groove, and the receiving groove is used to place the desiccant. The large fan ribs are provided with a through hole, which is connected to the receiving groove. The large fan ribs are covered with a cover plate for covering the opening of the receiving groove; Frame plate, a sliding groove is formed on the large fan bone, a notch communicating with the receiving groove is formed in the sliding groove, an installation rod movably matched with the sliding groove is installed on the frame plate, the sliding groove has a rotating end and a limiting end. When the installation rod slides to the rotating end, the axis of the installation rod is collinear with the axis of the hinge point of the large fan bone. When the installation rod slides to the limiting end, the frame plate contacts the side wall of the large fan bone, and the axis of the installation rod is not collinear with the axis of the hinge point of the large fan bone, so as to limit the rotation between the large fan bones.

[0006] Further, the frame plate includes a base plate connected to the installation rod, a U-shaped plate is slidably installed on the base plate, a limiting plate is slidably installed on the large fan bone, and a groove for accommodating the U-shaped plate is formed on the limiting plate.

[0007] Further, a plug rod is installed on the limiting plate, a jack for accommodating the plug rod is formed on the large fan bone, the free end of the plug rod is located in the sliding groove through the jack, a cavity is formed on the large fan bone, a rotating plate is rotatably installed in the cavity, a return spring is installed between the rotating plate and the cavity, a抵触 block penetrating the cavity is installed at one end of the rotating plate, the抵触 block is used to be抵触 by the plug rod, a shielding plate is installed at the other end of the rotating plate, and a through groove for the shielding plate to pass through is formed on the cavity.

[0008] Further, a counterweight block is installed on the U-shaped plate. When the installation rod moves to the rotating end, the counterweight block causes the U-shaped plate to rotate to the end of the large fan bone.

[0009] Further, a hinge rod is movably inserted into one of the large fan bones, and a receiving sleeve for accommodating the free end of the hinge rod is movably inserted into the other large fan bone. A plurality of extrusion grooves are formed at the free end of the hinge rod, a plurality of inserted sheets are installed in the receiving sleeve, and the free end of the hinge rod is in a frustum shape.

[0010] Further, the installation rod is slidably installed on the base plate, and an extrusion spring is installed between the base plate and the installation rod. The extrusion spring forces the free end of the installation rod to抵触 against the inner wall of the sliding groove.

[0011] Further, a T-shaped block is installed on the installation rod, protruding blocks are installed on the hinge rod and the receiving sleeve, and a T-shaped groove for accommodating the T-shaped block is formed on the protruding block.

[0012] Further, a magnet block is installed on the limiting plate, and an iron column is installed on the large fan bone. When the magnet block contacts the iron column, the sliding of the limiting plate is restricted.

[0013] Further, an installation block is installed on the large fan bone, a card hole is formed in the installation block, a protection plate is installed on the large fan bone, and a card rod for inserting into the card hole is installed on the protection plate, so that the protection plate is detachably connected to the large fan bone.

[0014] Furthermore, a hook plate is installed on the cover plate, and a hook groove for accommodating the hook end of the hook plate is provided in the accommodating groove.

[0015] The beneficial effects of the present application are as follows: In the present application, an accommodating groove is provided on the large fan bone, and a desiccant is arranged in the accommodating groove. When the art fan is folded, the art fan is dried by the desiccant. Moreover, the air fluidity in the accommodating groove is increased through the through holes and the notches, further reducing the possibility of the art fan being affected by moisture. A frame plate is installed on the large fan bone. When the art fan is in use, the frame plate is slid to the rotating end, and at this time, the art fan can be smoothly unfolded. When the art fan needs to be folded, the frame plate and the mounting rod are slid, so that the mounting rod is located at the limiting end and the frame plate contacts the large fan bone, restricting the rotation of the large fan bone, thereby reducing the possibility of the art fan being accidentally unfolded and contacting too much air during folding, and increasing the practicality.

[0016] When the art fan needs to be folded in the present application, first slide the limiting plate away from the large fan bone, then slide the frame plate. When it moves to the side of the limiting plate close to the rotating end, slide the C-shaped plate away from the substrate. At this time, continue to slide the frame plate to pass through the limiting plate, and then slide the C-shaped plate back to its original position. After the reset is completed, slide the frame plate so that the C-shaped plate is inserted into the groove. At this time, the mounting rod is located at the limiting end, and the movement tendency of the mounting rod towards the rotating end is restricted by the shielding of the limiting block, further increasing the stability of the frame plate during use, further reducing the possibility of the art fan being accidentally unfolded during folding, and increasing the practicality.

[0017] When the limiting plate does not slide in the present application, the end of the insertion rod抵触 the抵触 block, making the reset spring in a compressed state. At this time, the rotating plate is in an inclined state. When the rotating plate is in an inclined state, the shielding plate is located in the sliding groove through the through groove. The shielding plate is located at one end of the rotating plate close to the rotating end. At this time, the shielding plate shields the mounting rod, restricting the rotation of the frame plate, so that when the art fan needs to be used normally, the possibility of the frame plate accidentally sliding is reduced, and the stability of the device is increased.

[0018] When the art fan is in normal use in the present application, the counterweight block is located on the side of the C-shaped plate away from the large fan bone, so that when the mounting rod is located at the rotating end, affected by gravity, the C-shaped plate rotates and droops, and thus the frame plate will not affect the unfolding of the large fan bone, increasing the feasibility of the device.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0022] like Figure 1 - Fig.10 As shown, a moisture-proof process fan proposed in the first embodiment of the present application includes: There are two large fan ribs 1, which are hinged to each other, and fan surfaces and small fan ribs are installed between the large fan ribs 1. The small fan ribs are also hinged to the large fan ribs 1. The fan surfaces are attached between the large fan ribs 1 and the small fan ribs by glue or other means, so that the craft fan can be formed and used smoothly; A receiving groove 101 is provided on the large fan rib 1, and the receiving groove 101 is used to place a desiccant. A through hole 102 is provided on the large fan rib 1, and the through hole 102 is connected to the receiving groove 101. A cover plate 103 for covering the opening of the receiving groove 101 is provided on the large fan rib 1. A layer of gauze is attached to the large fan rib 1 by glue or other means, and the through hole 102 is covered by the gauze, so that air in the receiving groove 101 can circulate, and the through hole 102 is also covered by the gauze, thereby reducing the impact on the appearance of the process fan. When in use, a desiccant is placed in the receiving groove 101, so that the process fan can dry the surrounding air when it is placed, thereby reducing the possibility of the process fan being damp and increasing practicality. When in use, if the desiccant has been used for too long, the cover plate 103 is disassembled and the desiccant is replaced. After the replacement is completed, the cover plate 103 is used to cover the receiving groove 101 again, so that the device can continue to be used; The frame plate 2 and the large fan rib 1 are provided with a sliding groove 201, and a notch 104 communicating with the receiving groove 101 is provided in the sliding groove 201. When in use, the external airflow enters the receiving groove 101 through the notch 104, and then flows between the fan surface and the small fan rib through the through hole 102, thereby increasing the air flow, thereby reducing the possibility of water vapor in the air staying on the process fan for a long time, and reducing the possibility of the process fan being damp; A mounting rod 202 that movably cooperates with the sliding groove 201 is installed on the frame plate 2. The mounting rod 202 can slide in the sliding groove 201 along the length direction of the sliding groove 201 and rotate along the axis of the mounting rod 202 itself. The sliding groove 201 has a rotating end 2011 and a limiting end 2012. When the mounting rod 202 slides to the rotating end 2011, the axis of the mounting rod 202 is collinear with the axis of the hinge point of the large fan bone 1. When the mounting rod 202 slides to the limiting end 2012, the frame plate 2 contacts the side wall of the large fan bone 1, and the axis of the mounting rod 202 is not collinear with the axis of the hinge point of the large fan bone 1, so that the rotation between the large fan bone 1 is limited. When the craft fan needs to be used, when the mounting rod 202 is slid to the rotating end 2011, the frame plate 2 is rotated to make it rotate to the end of the large fan bone 1 so that it will not affect the deployment of the craft fan. When fanning, the large fan rib 1 is rotated to close the fan surface, and then the mounting rod 202 is slid to dislocate it from the hinge point of the large fan rib 1, so that the sliding groove 201 blocks the mounting rod 202, so that the two large fan ribs 1 are connected not only at the hinge point, but also connected to the frame plate 2 through the mounting rod 202. Through the restriction of the two connection points, the large fan ribs 1 cannot rotate relative to each other, so that the process fan will not be opened due to the possibility of mistaken rotation due to external force, and after the mounting rod 202 is slid to the outer wall, the mounting rod 202 is rotated to make the frame plate 2 contact with the side wall of the large fan rib 1, thereby increasing the contact area between the two, increasing friction, reducing the possibility of mistaken sliding of the mounting rod 202, further reducing the possibility of the process fan being exposed to the air while maintaining a large area, further reducing the possibility of the process fan being damp, and increasing practicality; Compared with the prior art, a receiving groove 101 is opened on the large fan rib 1, and a desiccant is arranged in the receiving groove 101. When the process fan is folded, the desiccant is used to dry the process fan, and the air flowability in the receiving groove 101 is increased through the through hole 102 and the notch 104, further reducing the possibility of the process fan being affected by moisture. A frame plate 2 is installed on the large fan rib 1. When the process fan is in use, the frame plate 2 is slid to the rotating end 2011, and the process fan can be smoothly unfolded. When the process fan needs to be folded, the frame plate 2 and the mounting rod 202 are slid so that the mounting rod 202 is located at the limiting end 2012 and the frame plate 2 is in contact with the large fan rib 1, so that the rotation of the large fan rib 1 is restricted, thereby reducing the possibility of the process fan being accidentally unfolded and exposed to too much air when folded, thereby increasing practicality. Embodiment 2

[0023] like Figure 5As shown, Embodiment 2 further discloses the large fan bone 1 and the frame plate 2 on the basis of Embodiment 1. In Embodiment 2, the frame plate 2 includes a substrate 203 connected to the mounting rod 202. A U-shaped plate 204 is slidably mounted on the substrate 203. A limiting plate 205 is slidably mounted on the large fan bone 1. A groove 206 for accommodating the U-shaped plate 204 is formed on the limiting plate 205. The sliding path of the U-shaped plate 204 is close to or away from the substrate 203, and the sliding path of the limiting plate 205 is close to or away from the large fan bone 1. When the limiting plate 205 slides away from the large fan bone 1, the width of the part of the large fan bone 1 where the limiting plate 205 is installed increases; When the art fan needs to be closed, first slide the limiting plate 205 away from the large fan bone 1, then slide the frame plate 2. When it moves to the side of the limiting plate 205 close to the rotating end 2011, slide the U-shaped plate 204 away from the substrate 203. At this time, the limiting plate 205 will not block the frame plate 2. Continue to slide the frame plate 2 so that it passes through the limiting plate 205, then slide the U-shaped plate 204 back to its original position. After the reset is completed, slide the frame plate 2 so that the U-shaped plate 204 is inserted into the groove 206. At this time, the mounting rod 202 is located at the limiting end 2012. The movement trend of the mounting rod 202 towards the rotating end 2011 is restricted by the shielding of the limiting plate 205, which further increases the stability of the frame plate 2 during use, further reduces the possibility of the art fan accidentally unfolding when being closed, and increases the practicality; When the art fan needs to be used, first slide the frame plate 2 to separate the U-shaped plate 204 from the groove 206, then slide the U-shaped plate 204 away from the substrate 203, slide the mounting rod 202 back to the rotating end 2011, and then slide the limiting plate 205 to reset. At this time, the art fan can be normally opened.

[0024] As Figure 4 、 Figure 5 、 Figure 8 、 Fig. 9 and Fig.10 As shown, in Embodiment 2, a plug rod 3 is installed on the limiting plate 205. A jack 4 for accommodating the plug rod 3 is formed on the large fan bone 1. The free end of the plug rod 3 is located in the sliding groove 201 through the jack 4. When the limiting plate 205 does not slide, the plug rod 3 is inserted into the jack 4 and the plug rod 3 lies across the inside of the sliding groove 201 to block the sliding of the mounting rod 202; A cavity 5 is formed on the large fan bone 1. A rotating plate 6 is rotatably mounted in the cavity 5. A return spring 7 is installed between the rotating plate 6 and the cavity 5. One end of the rotating plate 6 is provided with a抵触块 601 penetrating the cavity 5. The抵触块 601 is used to be抵触 by the plug rod 3. When the limiting plate 205 does not slide, the end of the plug rod 3抵触 the抵触块 601, so that the return spring 7 is in a compressed state, and the rotating plate 6 is in an inclined state at this time; A baffle plate 8 is installed at the other end of the rotating plate 6, and a through slot 9 is opened on the cavity 5 for the baffle plate 8 to pass through. When the rotating plate 6 is in a tilted state, the baffle plate 8 is located in the sliding slot 201 through the through slot 9, and the baffle plate 8 is located at the end of the rotating plate 6 close to the rotating end 2011. At this time, the baffle plate 8 blocks the mounting rod 202 and limits the rotation of the frame plate 2, so that when the process fan needs to be used normally, the possibility of accidental sliding of the frame plate 2 is reduced, thereby increasing the stability of the device.

[0025] like Figure 5 As shown, in the second embodiment, a counterweight 26 is installed on the mold plate 204. When the mounting rod 202 moves to the rotating end 2011, the counterweight 26 makes the mold plate 204 rotate to the end of the large fan rib 1. When the process fan is in normal use, the counterweight 26 is located on the side of the mold plate 204 away from the large fan rib 1, so that when the mounting rod 202 is located at the rotating end 2011, it is affected by gravity and makes the mold plate 204 rotate and droop, and rotate to Figure 2 The frame plate 2 is positioned in the middle, so that the expansion of the large fan rib 1 is not affected, thereby increasing the feasibility of the device.

[0026] like Figure 6 As shown, in the second embodiment, a hinge rod 10 is movably inserted on one of the large fan bones 1, and the hinge rod 10 can rotate on the large fan bone 1 and slide along its own axis direction, and a housing sleeve 11 for accommodating the free end of the hinge rod 10 is movably inserted on the other large fan bone 1, and the housing sleeve 11 can rotate on the large fan bone 1 and slide along its own axis direction, and a plurality of extrusion grooves 12 are provided at the free end of the hinge rod 10, and a plurality of inserting pieces 13 are installed in the housing sleeve 11, and the free end of the hinge rod 10 is truncated. When in use, when the connection between the fan bones is loose, the housing sleeve 11 and the hinge rod 10 are squeezed to make the end of the hinge rod 10 contact with the housing sleeve 11, and the friction between the two is increased by squeezing the groove 12 and the inserting piece 13, so that the housing sleeve 11 and the hinge rod 10 form a complete rod body, so that the craft fan can be used normally; The diameter of the accommodating sleeve 11 is larger than the diameter of the hinge rod 10, so that an end surface for being resisted by the accommodating sleeve 11 is formed between the part of the large fan rib 1 used to accommodate the accommodating sleeve 11 and the part of the large fan rib 1 used to accommodate the hinge rod 10. A plate body is installed on the hinge rod 10, and the diameter of the plate body is larger than the diameter of the hinge rod 10. Figure 6 As shown, when the two are in conflict, the accommodating sleeve 11 and the plate body located on the hinge rod 10 can also conflict with the large fan rib 1, so that the friction between the fan ribs is increased, thereby reducing the possibility of looseness between the fan ribs and increasing practicality.

[0027] like Figure 5As shown, in embodiment 2, the mounting rod 202 is slidably installed on the base plate 203, and a squeezing spring 14 is installed between the base plate 203 and the mounting rod 202. The squeezing spring 14 forces the free end of the mounting rod 202 to contact the inner wall of the sliding groove 201. When in use, the friction between the mounting rod 202 and the sliding groove 201 is increased by the squeezing spring 14, so that the user has obvious tactile feedback when sliding the frame plate 2, and when the large fan rib 1 is loose, the frame plate 2 is slid and rotated at the end 2011 to squeeze the mounting rod 202, so that the mounting rod 202 squeezes the hinge rod 10 and the accommodating sleeve 11, which makes it easy to clamp the fan ribs of the process fan. After the processing is completed, the mounting rod 202 is reset by resetting the squeezing spring 14, which increases the convenience of the device when in use.

[0028] like Figure 5 and Figure 6 As shown, in the second embodiment, a T-block 15 is installed on the mounting rod 202, and a protruding block 25 is installed on the hinge rod 10 and the accommodating sleeve 11. The protruding block 25 is provided with a T-slot 16 for accommodating the T-block 15. When in use, when the mounting rod 202 slides to the rotating end 2011, the T-block 15 is inserted into the T-slot 16. At this time, if the fan bone is rotated too tightly, the mounting rod 202 is pulled so that the two mounting rods 202 are separated from each other, so that the hinge rod 10 and the accommodating sleeve 11 are not in contact with each other. The clamping connection between the two is loose, which is convenient for adjusting the smoothness of the rotation of the entire process fan. When the device is used for too long and a small fan bone is broken, the installation rod 202 can be pulled to separate the accommodating sleeve 11 from the hinge rod 10, and then the frame plate 2 is pulled to separate the T-block 15 from the T-slot 16, and the hinge rod 10 and the accommodating sleeve 11 are separated from the large fan bone 1, and then the installation rod 202 is pulled away from each other to disconnect it from the large fan bone 1, and then the fan bone is disassembled for easy replacement, which increases practicality; Among them, because the protruding block 25 has a certain thickness, there is a certain distance between the deepest part of the T-slot 16 and the side where the protruding block 25 is installed on the hinged rod 10 or the accommodating sleeve 11. When the installation rod 202 pushes the hinged rod 10 or the accommodating sleeve 11 to slide a distance equal to this distance, the process fan can reach the tightest rotation state. Before the protruding block 25 moves to this state, the deepest part of the T-slot 16 will not be blocked by the inner wall of the sliding groove 201, so that the T-block 15 can be smoothly separated from the T-slot 16, thereby increasing the feasibility of the device. Embodiment 3

[0029] like Figure 1 - Fig.10As shown, in the third embodiment, a magnet block 17 is installed on the limiting plate 205, and an iron column 18 is installed on the large fan bone 1. When the magnet block 17 contacts the iron column 18, the sliding of the limiting plate 205 is restricted. During installation, a hand drill can be used to open a channel on the limiting plate 205 and the large fan bone 1, and then the magnet block 17 is installed on the limiting plate 205 and the iron column 18 is installed on the large fan bone 1 by glue. When the craft fan needs to be used, the iron column 18 is adsorbed by the magnet block 17 to restrict the sliding of the limiting plate 205, so that the limiting plate 205 will not slide accidentally during use, thereby causing the surrounding side of the fan bone to bulge, which may make the user feel uncomfortable when holding it, thereby increasing practicality. Furthermore, the sliding of the limiting plate 205 is restricted, so that the insertion rod 3 can maintain the resistance to the resistance block 601 , further increasing the stability of the rotating plate 6 when in use, thereby increasing the limiting effect of the shielding plate 8 on the mounting rod 202 .

[0030] In the third embodiment, a mounting block 19 is installed on the large fan rib 1, a clamping hole 20 is opened on the mounting block 19, a protective plate 21 is installed on the large fan rib 1, and a clamping rod 22 for being inserted into the clamping hole 20 is installed on the protective plate 21, so that the protective plate 21 and the large fan rib 1 can be detachably connected, and the protective plate 21 is used to shield the cover plate 103, and the outer surface of the protective plate 21 is arc-shaped, so that the process fan is more in line with the existing folding fan shape, such as Figure 1 As shown, the aesthetics of the device is increased.

[0031] A block is installed on the large fan rib 1, and a T-shaped groove is opened on the block. A plate body for being inserted into the above-mentioned groove is also installed on the protective plate 21. The clamping rod 22 is located at one end of the protective plate 21, and the plate body is located at the other end of the protective plate 21. When in use, the clamping rod 22 is clamped into the clamping hole 20 by sliding, and the plate body is inserted into the groove to connect the protective plate 21 to the large fan rib 1. The stability of the protective plate 21 when in use is increased by multiple connection points.

[0032] In embodiment three, a hook plate 23 is installed on the cover plate 103, and a hook groove 24 for accommodating the hook end of the hook plate 23 is opened in the accommodating groove 101. The hook plate 23 is made of plastic, and an arc-shaped groove body is opened on the large fan rib 1, so that a part of the cover plate 103 is exposed to the outside, which is convenient for the operator to better lift the cover plate 103 when replacing the desiccant, thereby increasing practicality.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
