Description

Technical Field

[0001] The present application relates to the technical field of folding fans, and in particular to a fan body structure with high applicability and a method of use. Background Art

[0002] The fan structure generally refers to an appliance that can generate wind by shaking. Among them, a folding fan is a fan that can be folded into a long strip for storage and transportation, and can be opened when in use, and then used for people to shake to fan the wind. When people go out for travel in summer, they often carry a folding fan with them to fan the wind to cool down.

[0003] Most existing folding fans include two fan frames and a foldable fan surface. The two fan frames are connected at the same end in the length direction and are rotatably connected through a rotating shaft. The fan surface is connected between two fan plates. When the two fan plates are close to each other and aligned, the fan surface can be completely folded between the two fan plates; when the two fan plates move away from each other, the fan surface can be spread between the two fan plates, so that people can shake the folding fan to fan the air.

[0004] However, when a traditional folding fan is opened and used, the fan can only be opened into a fan shape, so that the folding fan is not very useful except for fanning. As a result, the folding fan's function of cooling off when people go out in summer is relatively simple, and the applicability of the folding fan is low, which has obvious shortcomings. Summary of the invention

[0005] In order to improve the applicability of a folding fan, the present application provides a fan body structure with high applicability and a method of use.

[0006] A highly applicable fan structure provided in this application adopts the following technical solution: A fan body structure with high applicability includes a first fan frame and a second fan frame, a folding fan surface is arranged between the first fan frame and the second fan frame, and fixing components are arranged at the ends of the first fan frame and the second fan frame. The fixing component includes a protrusion arranged at the end of the second fan frame, and the end of the first fan frame is rotatably connected to a buckle frame buckled with the protrusion. A telescopic support rod is arranged on the first fan frame, and a sun-proof and rain-proof coating is coated on the surface of the folding fan surface facing away from the telescopic support rod.

[0007] By adopting the above technical scheme, when going out in summer, the user rotates the second fan frame in the direction away from the first fan frame. When the first fan frame and the second fan frame are in close contact and the folding fan surface is unfolded into a circle, the user rotates the buckle frame at the end of the second fan frame toward the direction of the protrusion at the end of the first fan frame, and makes the buckle frame and the protrusion accurately buckle. At this time, the state of the folding fan surface unfolded into a circle is fixed, and the user manually cranks the folding fan surface to achieve the purpose of fanning. When the sun is strong or it rains, the user holds the telescopic support rod and places the folding fan surface on the top of the head. The folding fan surface coated with a sunscreen and rainproof coating provides shade or shelter for the user, preventing the user from being troubled by direct sunlight and rain. Such a setting expands the use of the folding fan when going out in summer, enables the folding fan to meet more user needs when going out in summer, and improves the applicability of the folding fan.

[0008] Optionally, the telescopic support rod is rotatably connected to the surface of the first sash frame, and the first sash frame is provided with a U-shaped buckle that is snap-fitted with the telescopic support rod.

[0009] By adopting the above technical solution, when the user does not need to use the folding fan, the user retracts the telescopic strut and then rotates the telescopic strut in the direction of the U-shaped buckle. When the telescopic strut is in contact with the first fan frame, the telescopic strut is clipped into the U-shaped buckle. This arrangement enables the fan body to be stored when not in use, so that the telescopic strut does not become a protruding obstruction when stored, making the entire fan body structure more compact and easy to store and carry, thereby further improving the applicability of the folding fan.

[0010] Optionally, a support frame is provided on the end surface of the first fan frame facing away from the telescopic support rod, a photovoltaic panel is provided in the support frame, a mounting box is provided on the second fan frame, an energy storage device electrically connected to the photovoltaic panel is provided inside the mounting box, an LED lamp is provided at the end of the mounting box, and the LED lamp is electrically connected to the energy storage device.

[0011] By adopting the above technical solution, when the fan body is used as a parasol, the photovoltaic panel absorbs light energy and converts it into direct current through the photoelectric effect. The direct current is transmitted to the energy storage device, and the energy storage device stores the collected electrical energy. When night falls or in a dimly lit environment, the user presses the switch, and the energy storage device provides power to the LED lamp to light up, thereby giving the fan body a lighting function. This arrangement further expands the function of the folding fan, allowing the folding fan to meet the needs of users walking at night, thereby further improving the applicability of the folding fan.

[0012] Optionally, the support frame is made of a heat-conducting material, a heat dissipation cavity is provided inside the support frame, and the heat dissipation cavity is filled with a liquid phase change medium.

[0013] By adopting the above technical solution, the heat emitted by the photovoltaic panel during operation is transferred to the heat dissipation cavity through the support frame, and the liquid phase change medium absorbs the heat of the photovoltaic panel and turns into a gaseous phase change medium. The temperature of the photovoltaic panel surface and the heat dissipation cavity is reduced. Such a setting realizes the heat dissipation of the photovoltaic panel, so that the photovoltaic panel can continue to work efficiently at a relatively suitable temperature, which helps to maintain the normal operating temperature of the photovoltaic panel and human comfort. When the external temperature drops or the heat generation of the photovoltaic panel decreases, the gaseous phase change medium slowly releases heat and turns back into liquid, ensuring effective heat dissipation of the photovoltaic panel when the photovoltaic panel is operated next time.

[0014] Optionally, floating plates are slidably connected on both opposite sides of the heat dissipation cavity, an elastic water bag is arranged on the top wall of the heat dissipation cavity, the elastic water bag is arranged above the floating plate, the elastic water bag is filled with coolant, a plurality of water outlet pipes are connected to the elastic water bag, the water outlet directions of the water outlet pipes are all arranged toward the surface of the photovoltaic panel, and blocking frames corresponding to the floating plates are arranged on the inner side walls of the heat dissipation cavity. When the floating plate is overlapped on the surface of the blocking frame, the bottom surface of the elastic water bag overlaps on the surface of the floating plate and is in a natural state.

[0015] By adopting the above technical solution, when the liquid phase change medium absorbs heat and changes into a gaseous phase change medium, the air pressure in the heat dissipation cavity increases. When the air pressure below the floating plate is greater than the weight above the floating plate, the air pressure pushes the floating plate to move upward. At this time, the bottom surface of the elastic water bag is squeezed and deformed by the floating plate. The deformation of the elastic water bag drives the water level of the coolant to rise. When the water level rises to the water outlet pipe, the coolant is sprayed onto the surface of the photovoltaic panel through the water outlet pipe. After the coolant contacts the photovoltaic panel, it quickly takes away the heat from the surface of the photovoltaic panel. At the same time, through the arrangement of multiple water outlet pipes, the coolant is more evenly covered on the surface of the photovoltaic panel, thereby improving the uniformity of the heat dissipation effect. Such an arrangement further ensures that the photovoltaic panel can operate at a suitable temperature, thereby ensuring its photoelectric conversion efficiency and service life.

[0016] Optionally, an air pipe is provided on the support frame, and the air inlet end of the air pipe is connected to the interior of the heat dissipation cavity. An elastic airbag is sleeved on the outer surface of the handheld portion of the telescopic support rod, and an adjusting hose is connected to the elastic airbag. A control component for controlling the on-off of the air circuit is provided on the adjusting hose, and the adjusting hose is connected to the output end of the air pipe.

[0017] By adopting the above technical solution, when the user controls the air circuit to open through the control component, part of the gaseous phase change medium moves to the inside of the elastic airbag through the air pipe and the adjustment hose, and the volume of the elastic airbag expands after inflation. When the elastic airbag expands to a degree that is compatible with the comfortable grip of the human hand, the user controls the air circuit to close through the control component. At this time, the volume of the elastic airbag is locked. This setting realizes the adjustment of the size of the handheld part of the telescopic support rod, which is convenient for the user to flexibly adjust the expansion degree of the elastic airbag according to the size of his own palm, meets the usage needs of different users, and further improves the applicability of the folding fan.

[0018] Optionally, the control component includes a control sleeve mounted on the outer surface of the adjusting hose, and the opposite inner walls of the control sleeve are provided with control grooves, and the control grooves are inclined from top to bottom along the direction away from the adjusting hose. Connecting columns are slidably connected in two control grooves, and pressing blocks are provided on the two connecting columns. When the pressing block is set at the end of the control groove away from the elastic airbag, the pressing block squeezes the air pipe and makes the opposite inner walls of the air pipe fit tightly.

[0019] By adopting the above technical solution, when the elastic airbag needs to be inflated to increase the comfort of holding, the user slides the pressing block with one hand in the direction close to the elastic airbag, and under the guidance of the inclined control groove, the pressing surface of the pressing block gradually moves away from the adjusting hose, the degree of squeezing of the adjusting hose gradually decreases, and the gaseous phase change medium flows into the elastic airbag through the air supply pipe. When the elastic airbag expands to the required volume, the user slides the pressing block in the direction away from the elastic airbag, and the pressing surface of the pressing block gradually approaches the adjusting hose. When the pressing block slides to the end of the control groove away from the elastic airbag, the pressing block squeezes the air supply pipe and makes its relative inner walls fit tightly, the air circuit is closed, the gas in the elastic airbag cannot flow back through the adjusting hose, the volume of the elastic airbag remains stable, and the setting of the control component realizes the free opening and closing of the air circuit, which is convenient for the user to flexibly adjust the volume of the elastic airbag according to his own holding comfort. At the same time, the setting of the control component keeps the volume of the elastic airbag stable, further improving the comfort of the user's hand holding.

[0020] Optionally, a locking assembly is provided on the control sleeve, and the locking assembly includes a gear fixedly sleeved on the outer surface of the connecting column, and a locking groove connected to the control groove is opened on the inner side wall opposite to the control sleeve, and a rack plate meshing with the gear is slidably connected in the locking groove, and a spring is provided in the locking groove, one end of the spring is provided on the inner side wall of the locking groove, and the other end is provided on the rack plate, and the elastic force of the spring pushes the rack plate to move toward the inside of the control groove, and when the rack plate meshes with the gear, the pressing block is provided at the end of the control groove away from the elastic airbag, and the end face of the rack plate facing the control groove is a guide arc surface.

[0021] By adopting the above technical solution, when ventilation is needed, the user rotates the pressing block, and the rotation of the pressing block drives the gear to rotate, and the gear drives the rack plate to move toward the locking groove. When the rack plate moves to disengage from the gear, the user slides the pressing block downward through the guide slope to move it toward the elastic airbag; when ventilation is needed, the user slides the pressing block upward, and when the gear moves close to the rack plate, the gear pushes the rack plate toward the locking groove under the guidance of the guide slope. At this time, the spring is compressed, and when the pressing block moves to the end of the control groove, the horizontal thrust on the spring disappears, and the spring is restored. The rack plate is pushed to move in the direction of the control groove, and the rack plate is meshed with the gear. Under the obstruction of the rack plate, the gas in the gas pipe is difficult to push the pressing block to rotate so that the rack plate is separated from the control groove. The disconnected state of the gas path is locked by the locking component. The setting of the locking component realizes the locking of the gas-off state of the pressing block, avoiding the spontaneous sliding of the pressing block due to excessive gas pressure inside the gas pipe, and ensuring the stability of the gas-off state. At the same time, the user can unlock the locking component only by rotating the pressing block, which is easy to operate and convenient for the user to operate while holding the telescopic support rod.

[0022] A method for using the fan structure with high applicability comprises the following steps in sequence: S1, unfolding the fan: the user rotates the second fan frame in a direction away from the first fan frame until the first fan frame and the second fan frame are tightly attached and the folded fan surface is completely unfolded into a circle; S2, fixing the fan surface: the user rotates the buckle frame at the end of the first fan frame toward the convex block at the end of the second fan frame, so that the buckle frame and the convex block are buckled and matched; S3. Use of folding fan: The user holds the first fan frame or the second fan frame and swings the folding fan back and forth by swinging the arm to achieve fanning; S4: Use of parasol: The user pulls the telescopic support rod to disengage the U-shaped buckle, adjusts the length of the telescopic support rod according to their needs, holds the telescopic support rod and places the folding fan on the head to achieve sunshade; S5: Folding the fan, the user rotates the buckle frame in a direction away from the second fan frame, the buckle frame disengages from the protrusion, and then rotates the second fan frame in a direction close to the first fan frame to restore the folded fan to the folded state, and finally fixes the folded state of the fan through step S2; S6. Storing the telescopic support rod: the user shortens the telescopic support rod to the shortest length, rotates it to a position that fits with the first sash frame, and clips the telescopic support rod into the U-shaped buckle; S7. Storing the fan body: The user places the folded fan body into a special storage space.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a fixed component and a telescopic support rod, and the user unfolds the folding fan surface through the fixed component. When the sun is strong or it is raining, the user holds the telescopic support rod and places the folding fan surface on the head. The folding fan surface coated with a sunscreen and rainproof coating provides shade or shelter for the user, thereby preventing the user from being exposed to direct sunlight and being wetted by rain. 2. The present application sets a heat dissipation cavity, a liquid phase change medium and an elastic water bag. During the operation of the photovoltaic panel, the liquid phase change medium absorbs heat and turns into a gaseous phase change medium. The gaseous phase change medium pushes the floating plate to move upward, and the floating plate squeezes the elastic water bag. The coolant in the elastic water bag is sprayed onto the surface of the photovoltaic panel to reduce the temperature of the photovoltaic panel surface. This setting realizes multiple cooling of the photovoltaic panel, ensures that the photovoltaic panel can work at a suitable temperature, guarantees the photoelectric conversion efficiency and service life of the photovoltaic panel, and at the same time guarantees the user's comfort. 3. The present application provides an air pipe, an adjusting hose, an elastic airbag, a control component and a locking component. When the user needs to adjust the comfort level of the handheld portion of the telescopic support pole, the user controls the air circuit to open through the control component, and part of the gaseous phase change medium moves to the inside of the elastic airbag through the air pipe and the adjusting hose. The elastic airbag expands in volume after being inflated. When the elastic airbag expands to a level that matches the comfortable grip of a human hand, the user controls the air circuit to close through the control component, and then locks the closed state of the air circuit through the locking component to prevent the air pressure from pushing the pressing block to slide. At this time, the volume of the elastic airbag is locked, thereby achieving the adjustment of the size of the handheld portion of the telescopic support pole, and facilitating the user to flexibly adjust the expansion level of the elastic airbag according to the size of his or her palm.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The embodiments of the present application disclose a fan structure with high applicability and a method of use.

[0032] Example 1 Reference Figure 1 and Figure 2 A fan body structure with high applicability includes a first fan frame 1 and a second fan frame 2 which are rotatably connected via a rotating shaft, and a folding fan surface 3 is installed in the first fan frame 1 and the second fan frame 2. When the first fan frame 1 and the second fan frame 2 are close to each other and aligned, the folding fan surface 3 is completely folded between the first fan frame 1 and the second fan frame 2.

[0033] When fanning oneself when going out in the summer, the user rotates the second fan frame 2 in a direction away from the first fan frame 1. During the rotation of the second fan frame 2, the area of ​​the folding fan surface 3 gradually increases until it unfolds into a circle. At this time, the user holds the first fan frame 1 and the second fan frame 2 and drives the folding fan surface 3 to swing back and forth. During the swinging process, the air flow rate around the user is accelerated to achieve the effect of fanning. After the fanning is completed, the user rotates the second fan frame 2 in a direction close to the first fan frame 1. During the rotation of the second fan frame 2, the unfolded area of ​​the folding fan surface 3 gradually decreases. When the folding fan surface 3 is completely stored between the first fan frame 1 and the second fan frame 2, the folding fan is completely stored.

[0034] Reference Figure 1 and Figure 2 In order to improve the stability of the fan body structure when in use, a fixing component 4 is provided at the ends of the first fan frame 1 and the second fan frame 2. The fixing component 4 includes a protrusion 41 fixedly connected to the end of the second fan frame 2. The protrusion 41 and the second fan frame 2 are integrally formed. The end of the first fan frame 1 is rotatably connected to a buckle frame 42 that is buckled and matched with the protrusion 41. When the buckle frame 42 is buckled on the protrusion 41, the first fan frame 1 and the second fan frame 2 abut against each other.

[0035] When the folding fan 3 is unfolded or folded, the first fan frame 1 and the second fan frame 2 are in a state of close contact with each other. At this time, the user rotates the buckle frame 42 on the first fan frame 1 toward the second fan frame 2, and makes the buckle frame 42 accurately buckle with the protrusion 41. Under the buckling cooperation between the buckle frame 42 and the protrusion 41, the unfolded or folded state of the folding fan 3 is fixed, reducing the possibility of deformation of the folding fan 3 due to external force, thereby ensuring smooth use by the user.

[0036] Reference Figure 1 and Figure 2 A telescopic support rod 5 is hinged on the first fan frame 1 through a rotating seat. The telescopic support rod 5 is a prior art and will not be described in detail here. The surface of the folding fan surface 3 away from the telescopic support rod 5 is coated with a rainproof and sun-proof coating.

[0037] When the sun is shining brightly or it is raining, the user can place the folding fan 3 on the top of the head by holding the telescopic support rod 5. The folding fan 3 coated with a sun-proof and rain-proof coating can provide shade or shelter for the user, preventing the user from being exposed to direct sunlight or getting wet by rain. At the same time, the user can adjust the height of the folding fan 3 from the top of the head by adjusting the length of the telescopic support rod 5.

[0038] Reference Figure 1 and Figure 2 A U-shaped buckle 6 which is engaged with the telescopic support rod 5 is fixedly connected to the first sash frame 1 . When the telescopic support rod 5 is engaged with the U-shaped buckle 6 , the rod body of the telescopic support rod 5 is tightly attached to the surface of the first sash frame 1 .

[0039] When the user does not need to use the folding fan, the user retracts the telescopic support rod 5 and then rotates the telescopic support rod 5 toward the direction of the U-shaped buckle 6. When the telescopic support rod 5 is in contact with the first fan frame 1, the telescopic support rod 5 is clipped into the U-shaped buckle 6. This arrangement enables the fan body to be stored when not in use, so that the telescopic support rod 5 will not become a protruding obstruction when stored, making the entire fan body structure more compact and convenient for storage and carrying, thereby further improving the applicability of the folding fan. The implementation principle of a highly applicable fan body structure in an embodiment of the present application is as follows: when going out in summer, the user rotates the second fan frame 2 in a direction away from the first fan frame 1. When the first fan frame 1 and the second fan frame 2 are in close contact and the folding fan surface 3 is unfolded into a circle, the user rotates the buckle frame 42 at the end of the first fan frame 1 toward the protrusion 41 at the end of the second fan frame 2, and makes the buckle frame 42 accurately buckle with the protrusion 41. At this time, the folding fan surface 3 is unfolded into a circle and is fixed. The user manually cranks the folding fan surface 3 to achieve the purpose of fanning. When the sun is strong or it rains, the user holds the telescopic support rod 5 and places the folding fan surface 3 on the top of the head. The folding fan surface 3 coated with a sunscreen and rainproof coating provides shade or shelter for the user, preventing the user from being troubled by direct sunlight and rain. Such a setting expands the use of the folding fan when going out in summer, enables the folding fan to meet more user needs when going out in summer, and improves the applicability of the folding fan.

[0040] Example 2 Reference Figure 3 The difference between the embodiment of the present application and embodiment 1 is that the end face of the first fan frame 1 facing away from the telescopic support rod 5 is fixedly connected to a support frame 7, the support frame 7 is U-shaped, and a photovoltaic panel 71 is fixedly installed on the surface of the support frame 7, and the end face of the second fan frame 2 facing away from the telescopic support rod 5 is fixedly connected to a mounting box 8, and an energy storage device 81 (not shown in the figure) electrically connected to the photovoltaic panel 71 is fixedly installed inside the mounting box 8, and an LED lamp 82 is fixedly installed at the end of the mounting box 8 away from the center of the folding fan surface 3, and the LED lamp 82 is electrically connected to the energy storage device 81. Providing electrical energy to the energy storage device 81 through the photovoltaic panel 71 is a prior art and will not be repeated here. A switch for controlling the opening and closing of the LED lamp 82 is installed on the outer surface of the mounting box 8.

[0041] When used as a parasol, the photovoltaic panel 71 absorbs light energy and converts it into direct current through the photoelectric effect. The direct current is transmitted to the energy storage device 81, which stores the collected electrical energy. When night falls or in a dimly lit environment, the user presses the switch, and the energy storage device 81 provides power to the LED lamp 82 to light up, thereby giving the fan body a lighting function. This further expands the function of the folding fan, allowing the folding fan to meet the needs of users walking at night, further improving the applicability of the folding fan.

[0042] Reference Figure 3 and Figure 4 The photovoltaic panel 71 will emit a large amount of heat when working. The accumulation of heat will cause the temperature of the folding fan 3 to rise, so that the user will feel hot under the folding fan 3. At the same time, the excessively high temperature will cause the photoelectric conversion efficiency of the photovoltaic panel 71 to decrease, thus affecting the service life of the photovoltaic panel 71.

[0043] In order to solve the above technical problems, the support frame 7 is supported by a thermally conductive material with a high thermal conductivity coefficient. A heat dissipation cavity 9 is opened inside the support frame 7, and the heat dissipation cavity 9 is filled with a liquid phase change medium 91 (not shown in the figure). In this embodiment, the evaporation temperature of the liquid phase change medium 91 is 40℃-50℃.

[0044] Reference Figure 3 and Figure 4 Floating plates 92 are slidably connected to the opposite sides of the heat dissipation cavity 9. The length direction of the floating plates 92 is parallel to the length direction of the photovoltaic panel 71. An elastic water bag 93 is arranged above each floating plate 92. The top wall of the elastic water bag 93 is fixedly connected to the inner top wall of the heat dissipation cavity 9. Each elastic water bag 93 is filled with coolant. A plurality of water outlet pipes 931 are connected to the elastic water bag 93. The plurality of water outlet pipes 931 are evenly distributed along the length direction of the photovoltaic panel 71. The water outlets of the support frame 1 all penetrate the side wall of the support frame 7 and extend to the surface of the photovoltaic panel 71. The water outlet directions of the multiple water outlet pipes 931 are all arranged toward the surface of the photovoltaic panel 71. The inner wall of the heat dissipation cavity 9 is fixedly connected with a blocking frame 94 corresponding to the floating plate 92. The blocking plate is located below the floating plate 92, and the height of the bottom surface of the blocking plate is located above the horizontal plane of the liquid phase change medium 91. When the floating plate 92 is overlapped on the surface of the blocking frame 94, the bottom surface of the elastic water bag 93 is overlapped on the surface of the floating plate 92 and is in a natural state.

[0045] The heat emitted by the photovoltaic panel 71 during operation is transferred to the heat dissipation cavity 9 through the support frame 7. The liquid phase change medium 91 absorbs the heat of the photovoltaic panel 71 and turns into a gaseous phase change medium. The temperature of the surface of the photovoltaic panel 71 and the heat dissipation cavity 9 decreases. As the number of phase changes of the liquid phase change medium 91 increases, the air pressure in the heat dissipation cavity 9 continues to increase. When the air pressure under the floating plate 92 is greater than the weight of the floating plate 92, the elastic water bag 93 and the coolant, the air pressure pushes the floating plate 92 to move upward. At this time, the bottom surface of the elastic water bag 93 is squeezed by the floating plate 92 and deformed. The deformation of the elastic water bag 93 drives the water level of the coolant to rise. When the water level rises to the water outlet pipe 931, the coolant is sprayed onto the surface of the photovoltaic panel 71 through the water outlet pipe 931. After the coolant contacts the photovoltaic panel 71, it quickly takes away the heat on the surface of the photovoltaic panel 71. At the same time, through the setting of multiple water outlet pipes 931, the coolant is more evenly covered on the surface of the photovoltaic panel 71, thereby improving the uniformity of the heat dissipation effect. The setting of the liquid phase change medium 91 and the coolant realizes multiple cooling of the photovoltaic panel 71, ensuring that the photovoltaic panel 71 can work at a suitable temperature, ensuring the photoelectric conversion efficiency and service life of the photovoltaic panel 71, and at the same time ensuring the comfort of the user.

[0046] When the outside temperature decreases or the heat generated by the photovoltaic panel 71 decreases, the gaseous phase change medium slowly releases heat and turns back into the liquid phase change medium 91, thereby ensuring effective heat dissipation of the photovoltaic panel 71 when the photovoltaic panel 71 operates next time.

[0047] Reference Figure 3 , Figure 5 and Figure 6 An air pipe 10 is fixedly installed on the outer surface of the support frame 7. The air pipe 10 is connected to the inside of the heat dissipation cavity 9. The air inlet end of the air pipe 10 is located above the floating plate 92. The surfaces opposite to the first fan frame 1 and the second fan frame 2 are provided with an avoidance groove (not shown in the figure) for the air pipe 10 to pass through. The air pipe 10 passes through the avoidance groove and extends downward along the length direction of the telescopic support rod 5. An elastic air bag 11 is fixedly connected to the outer surface of the handheld portion of the telescopic support rod 5. The elastic air bag 11 is sleeved on the outer surface of the telescopic support rod 5. An adjusting hose 12 is connected to the elastic air bag 11. A control component 13 for controlling the on-off of the air path is provided on the adjusting hose 12. The adjusting hose 12 is connected to the output end of the air pipe 10. The length portion of the air pipe 10 parallel to the telescopic support rod 5 is a bellows. When the telescopic support rod 5 contracts, the corrugated section of the air pipe 10 contracts.

[0048] Reference Figure 3 , Figure 5 and Figure 6 The control assembly 13 includes a control sleeve 131 fixedly sleeved on the outer surface of the regulating hose 12, the control sleeve 131 is U-shaped, and the inner side walls opposite to the control sleeve 131 are provided with control grooves 14, the control grooves 14 are inclined from top to bottom along the direction away from the regulating hose 12, and the cross-section of the control grooves 14 perpendicular to the length direction is T-shaped, and connecting columns 132 are slidably connected in the two control grooves 14, and a pressing block 133 is commonly connected to the two connecting columns 132. In this embodiment, the pressing block 133 is a cylindrical block, and the pressing block 133 is slidably connected to the opening of the control sleeve 131 along the length direction of the control groove 14. A plurality of anti-slip convex grooves are fixedly connected to the outer surface of the pressing block 133. When the pressing block 133 is arranged at the end of the control groove 14 away from the elastic airbag 11, the pressing block 133 squeezes the air pipe 10 and makes the opposite inner wall of the air pipe 10 fit tightly.

[0049] Reference Figure 3 , Figure 5 and Figure 6 The air pipe 10, the regulating hose 12 and the elastic airbag 11 are all made of a heat-insulating material with a low thermal conductivity coefficient, which reduces the influence of the external temperature on the gaseous phase change medium when it flows in the air pipe 10, the regulating hose 12 and the elastic airbag 11, and improves the temperature suitability when the user holds it.

[0050] When the elastic airbag 11 needs to be inflated to increase the comfort of holding, the user slides the pressing block 133 with one hand in the direction close to the elastic airbag 11. Under the guidance of the inclined control groove 14, the pressing surface of the pressing block 133 gradually moves away from the regulating hose 12, and the degree of compression of the regulating hose 12 gradually decreases. The gaseous phase change medium flows into the elastic airbag 11 through the air delivery pipe 10. When the elastic airbag 11 expands to the required volume, the user slides the pressing block 133 in the direction away from the elastic airbag 11, and the pressing surface of the pressing block 133 gradually approaches the regulating hose 12. When the pressing block 133 slides When the control groove 14 is away from the end of the elastic airbag 11, the pressing block 133 squeezes the air pipe 10 and makes the opposite inner walls of the air pipe 10 fit tightly. At this time, the air circuit is closed, and the gas in the elastic airbag 11 cannot flow back through the adjusting hose 12. The volume of the elastic airbag 11 remains stable. The setting of the control component 13 and the elastic airbag 11 realizes the adjustment of the size of the hand-held part of the telescopic support rod 5, which is convenient for the user to flexibly adjust the volume of the elastic airbag 11 according to his own holding comfort. At the same time, the setting of the control component 13 keeps the volume of the elastic airbag 11 stable, further improving the user's holding comfort.

[0051] Reference Figure 3 , Figure 5 and Figure 6 In order to improve the stability when the gas circuit is disconnected, a locking assembly 15 is provided on the control sleeve 131. The locking assembly 15 includes a gear 151 fixedly sleeved on the outer surface of the connecting shaft. The gear 151 is slidably connected to the inside of the control groove 14. A locking groove 141 connected to the control groove 14 is provided on the inner side wall opposite to the control sleeve 131. The length direction of the locking groove 141 is perpendicular to the length direction of the telescopic support rod 5. A rack plate 152 meshing with the gear 151 is slidably connected in each locking groove 141. A spring 153 is provided in each locking groove 141. One end of the spring 153 is fixedly connected to the inner side wall of the locking groove 141 away from the control groove 14. The other end is fixedly connected to the rack plate 152, and the elastic force of the spring 153 pushes the end of the rack plate 152 to move toward the inside of the control groove 14. When the spring 153 is in a natural state, the end of the rack plate 152 extends to the inside of the control groove 14. In this embodiment, in order to ensure the pushing effect of the elastic force of the spring 153, the spring 153 is sleeved on the outer surface of the guide rod, and a guide groove that slides with the guide rod is opened on the rack plate 152. When the rack plate 152 is engaged with the gear 151, the pressing block 133 is arranged at the end of the control groove 14 away from the elastic airbag 11, and the end face of the rack plate 152 facing the control groove 14 is a guide arc surface 1521.

[0052] When ventilation is needed, the user rotates the pressing block 133, and the pressing block 133 rotates to drive the gear 151 to rotate, and the gear 151 drives the rack plate 152 to move toward the locking groove 141. When the rack plate 152 moves to disengage from the gear 151, the user slides the pressing block 133 downward through the guide slope, and the pressing block 133 moves toward the elastic airbag 11, and the air path is opened; When it is necessary to cut off the air, the user slides the pressing block 133 upwards, and the pressing block 133 gradually moves toward the direction of the folding fan 3. When the gear 151 moves to abut against the rack plate 152, the gear 151 pushes the rack plate 152 to move toward the direction close to the locking groove 141 under the guidance of the guide slope. At this time, the spring 153 is compressed. When the pressing block 133 moves to the end of the control groove 14 away from the elastic airbag 11, the air path is closed, and the horizontal thrust on the spring 153 disappears. The spring 153 resets and pushes the rack plate 152 to move toward the direction of the control groove 14. The rack plate 152 and the gear 151 form a The rack plate 152 is blocked by the gas in the gas pipe 10, so that the gas in the gas pipe 10 can hardly push the pressing block 133 to rotate and thus the rack plate 152 can be separated from the control groove 14. The disconnected state of the gas circuit is locked by the cooperation of the rack plate 152 and the gear 151. The setting of the locking assembly 15 realizes the locking of the gas-off state of the pressing block 133, thereby avoiding the spontaneous sliding of the pressing block 133 caused by the excessive gas pressure inside the gas pipe 10, and ensuring the stability of the gas-off state. At the same time, the user can unlock the locking assembly 15 by simply rotating the pressing block 133, which is easy to operate and convenient for the user to operate when holding the telescopic support rod 5.

[0053] The implementation principle of Example 2 of the present application is as follows: when the fan body is used as a sunshade, the light plate absorbs light energy and converts it into electrical energy, which is stored in the energy storage device 81 to provide electrical energy for the LED lamp 82. When night falls or in a dark environment, the user presses the switch, and the energy storage device 81 provides power to the LED lamp 82 to light up, so that the fan body has a lighting function; During the operation of the photovoltaic panel 71, the liquid phase change medium 91 absorbs heat and transforms into a gaseous phase change medium. The gaseous phase change medium pushes the floating plate 92 to move upward, and the floating plate 92 squeezes the elastic water bag 93. The cooling liquid in the elastic water bag 93 is sprayed onto the surface of the photovoltaic panel 71 to reduce the temperature of the surface of the photovoltaic panel 71. When the user needs to adjust the comfort level of the hand-held portion of the telescopic support rod 5, the user controls the air circuit to open through the control component 13, and part of the gaseous phase change medium moves to the inside of the elastic airbag 11 through the air pipe 10 and the adjustment hose 12. The volume of the elastic airbag 11 expands after inflation. When the elastic airbag 11 expands to a level that matches the comfortable grip of the human hand, the user controls the air circuit to close through the control component 13, and then locks the air circuit closure state through the locking component 15 to prevent the air pressure from pushing the pressing block 133 to slide. At this time, the volume of the elastic airbag 11 is locked, thereby realizing the adjustment of the size of the hand-held portion of the telescopic support rod 5, which is convenient for the user to flexibly adjust the expansion degree of the elastic airbag 11 according to the size of his own palm, meets the usage needs of different users, and further improves the applicability of the folding fan.
