Description

Technical Field

[0001] This invention relates to the field of folding umbrella technology, specifically to a multifunctional folding umbrella that uses clean energy. Background Technology

[0002] A folding umbrella is a tool that can provide shade or shield against rain, snow, and sun. Umbrellas are needed in daily life for sun protection and cooling, but existing folding umbrellas still have some shortcomings.

[0003] In existing technologies, such as the outdoor smart folding umbrella disclosed in CN115349698A, a hinge chain, a secondary shading curtain, a connecting rod, and a sliding block are used. The hinge chain connecting the supporting umbrella ribs and the sliding shell serves as the central hinge connection, allowing the groove at the bottom of the supporting umbrella ribs to form a passage with the groove in the sliding shell. The sliding block then slides into the sliding shell through the groove in the supporting umbrella rib. The connecting rod is then installed onto the sliding block through the insertion relationship between the connecting rod and the sliding block. The secondary shading curtain on the side of the connecting rod is then installed around the perimeter of the canopy to form auxiliary shading, thereby improving the overall shading effect and achieving full shading when the sun shines from different angles. However, it can only effectively block sunlight and lacks a cooling device, failing to provide users with proper and effective cooling.

[0004] In addition, existing technologies, such as the solar-powered folding umbrella with publication number CN115227010A, use a structure that includes a lithium battery pack, LED lights, Bluetooth speaker, and fan. This allows the solar-powered folding umbrella to provide power to electronic products such as computers, mobile phones, cameras, lights, tablets, and power banks while people enjoy the shade provided by the umbrella, meeting the power needs of these devices. It can also provide lighting and play music, satisfying various leisure needs. However, its solar power generation structure lacks protection and cleaning mechanisms, which can easily damage the solar panels with long-term use, reducing the lifespan of the folding umbrella.

[0005] In addition, existing technologies, such as the foldable umbrella rib disclosed in CN214340575U, facilitate the adjustment of the height of the foldable umbrella rib body and the separation between the foldable umbrella rib body and the support base through the cooperation of the foldable umbrella rib body, connecting plate, support base, limiting tube, first lead screw, nut, movable ring, support block, groove, fixing plate, drive assembly and adjustment assembly. At the same time, it can adjust the distance between the support block and the support base according to actual needs to increase the stability of the foldable umbrella rib body when placed. However, its base is a fixed structure, and the foldable umbrella needs to be lifted for transportation during the process, which reduces the convenience of using the foldable umbrella and has certain defects. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional folding umbrella that uses clean energy, in order to solve the problems mentioned in the background art that the current folding umbrellas on the market lack cooling devices, require manual cleaning of the solar structure, and are inconvenient to move.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional folding umbrella using clean energy, comprising: a base, a support frame fixedly connected to the upper surface of the base, an umbrella handle slidably connected inside the support frame, a winch shell fixedly connected to the outer surface of the umbrella handle, and a crossbar rotatably connected to the upper surface of the umbrella handle.

[0008] It also includes: a vertical bar, which is fixedly connected to the end face of the horizontal bar;

[0009] The ash collection box is slidably connected to the outer side of the crossbar, and there are two ash collection boxes symmetrically arranged about the middle of the crossbar;

[0010] The first pivot is rotatably connected inside the crossbar;

[0011] The second pivot is rotatably connected inside the crossbar.

[0012] Preferably, the base is rotatably connected to a screw, and the outer side of the screw is threadedly connected to a collar, and the outer side of the collar is rotatably connected to a crank. At the same time, four cranks are arranged at equal angles about the collar axis, and the lower end of the crank is fixedly connected to a universal wheel. The upper surface of the base is fixedly connected to a cover plate.

[0013] By adopting the above technical solution, water can be injected into the base through the opening on the upper surface of the cover plate, giving the base good stability. When the base needs to be moved, the screw is rotated, and under the action of the threaded connection, the collar height is raised, thereby pressing down the crank end face to achieve the support of the caster wheel on the base, thus making it easy to move the base.

[0014] Preferably, a winch handle is rotatably connected inside the winch housing, and a traction rope is rotatably connected to the outer side of the winch handle, with the other end of the traction rope rotatably connected to the outer side of the first rotating shaft.

[0015] By adopting the above technical solution, the length of the released part of the traction rope can be controlled by rotating the winch handle.

[0016] Preferably, a ratchet is fixedly connected to the outer side of the winch handle, and a limit plate is rotatably connected inside the winch housing. The end face of the limit plate is engaged with the ratchet. At the same time, a spring is fixedly connected to the lower surface of the limit plate, and the other end of the spring is fixedly connected to the inside of the winch housing. An unlocking rod is fixedly connected to the outer side of the limit plate.

[0017] By adopting the above technical solution, rotating the winch handle causes the ratchet to push the limiting plate. Under the action of the spring force, the limiting plate slides into the next meshing tooth of the ratchet, thereby achieving the limiting support of the ratchet, preventing the ratchet from reversing, and realizing the self-locking function of the folding umbrella. When it is necessary to retract the folding umbrella, press the unlocking lever to make the limiting plate leave the ratchet, thereby unlocking the ratchet and realizing the reversal of the ratchet. After the reversal is completed, release the unlocking lever, and under the action of the spring force, the limiting plate re-locks into the ratchet meshing tooth, realizing the locking of the ratchet.

[0018] Preferably, the other end of the traction rope is rotatably connected to the second rotating shaft, and a pull rod is fixedly connected to the lower end face of the traction rope. An auxiliary frame is rotatably connected to the outer side of the pull rod, and multiple auxiliary frames are arranged at equal angles about the axis of the pull rod. An umbrella rib is rotatably connected to the outer side of the vertical rod, and multiple umbrella ribs are arranged at equal angles about the axis of the vertical rod. The end face of the auxiliary frame is rotatably connected to the outer side of the umbrella rib. An external buckle is slidably connected to the lower surface of the pull rod. The external buckle is made of elastic material, and a mosquito repellent liquid tank, a light, and a charging port are fixedly connected to the lower surface of the external buckle.

[0019] By adopting the above technical solution, rotating the winch handle drives the traction rope to rotate and retract, thereby raising the position of the pull rod, causing the auxiliary frame to rotate, and the auxiliary frame to push the umbrella ribs to unfold outward, thus realizing the unfolding of the folding umbrella. At the same time, the external buckle can be freely removed from the lower surface of the pull rod, making it convenient to use the mosquito repellent liquid tank, the light, and the charging port.

[0020] Preferably, a hydraulic push rod is rotatably connected to the outer side of the umbrella handle, and the other end of the hydraulic push rod is rotatably connected to the outer side of the crossbar. Two hydraulic push rods are symmetrically arranged about the middle of the umbrella handle.

[0021] By adopting the above technical solution, the angle between the umbrella handle and the crossbar can be adjusted by activating the hydraulic push rod, thereby adjusting the orientation of the folding umbrella. By setting the automatic start and stop time of the hydraulic push rod, the effect of adjusting the folding umbrella according to the angle of sunlight can be achieved.

[0022] Preferably, a solar panel is rotatably connected to the outer side of the crossbar, and a ceramic protective plate is fixedly connected to the lower surface of the solar panel. Multiple solar panels are arranged side by side. Meanwhile, a belt is driven to the outer side of the second rotating shaft, and a cleaning brush is fixedly connected to the inner side of the belt. A lever is also fixedly connected to the inner side of the belt.

[0023] By adopting the above technical solution, when using the folding umbrella, the solar panel can convert solar energy into electrical energy to power the umbrella. When the umbrella is folded up, the traction rope drives the second rotating shaft to rotate, which in turn drives the cleaning brush and lever to move. After the cleaning brush has finished cleaning the dust on the surface of the solar panel, the lever rotates the solar panel so that the solar panel faces down and the ceramic protective plate faces up. The cleaned dust falls into the dust collection box, thus achieving automatic cleaning and protection of the solar panel.

[0024] Preferably, a water tank is fixedly connected to the lower surface of the crossbar, and the water tank is fixedly connected to the upper surface of the atomizing nozzle through a water pipe, and the atomizing nozzle is fixedly connected to the outer side of the vertical bar.

[0025] By adopting the above technical solution, the atomizing nozzle can atomize the water inside the water tank and spray it into the folding umbrella, thereby achieving cooling of the inside of the folding umbrella.

[0026] Preferably, a toothed ring is rotatably connected to the outer side of the vertical rod, and a gear is meshed with the outer side of the toothed ring. A motor is fixedly connected to the gear shaft end. At the same time, a fan blade is rotatably connected to the outer side of the toothed ring, and multiple fan blades are arranged at equal angles about the axial direction of the toothed ring. An air pump is fixedly connected to the outer side of the vertical rod. Meanwhile, the inside of the umbrella rib is hollow, and an air outlet is fixedly connected to the end face of the umbrella rib.

[0027] By adopting the above technical solution, the motor is started, the gear rotates under the motor drive, the gear ring rotates under the meshing connection, and the fan blades rotate and unfold under the centrifugal force to blow air into the inside of the folding umbrella. At the same time, the air pump is started, and air is delivered through the umbrella ribs to the air outlet and sprayed out, thereby limiting the water mist and preventing the water mist from spreading and seriously affecting the cooling effect.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the multifunctional folding umbrella using clean energy can achieve convenient movement of the base, has a self-locking function for opening and closing, and the solar panel can be automatically cleaned, effectively improving the ease of use of the folding umbrella. The specific details are as follows:

[0029] 1. It is equipped with a screw, collar, crank and base. When the base needs to be moved, the screw is rotated. Under the action of the threaded connection, the collar rotates and rises along the outer surface of the screw, thereby driving the crank to rotate. This causes the end face of the crank to press down, so that the caster wheel contacts the ground, realizing the support of the caster wheel for the base, thus making it easy to move the base.

[0030] 2. It is equipped with a winch handle, ratchet, limit plate and spring. When the folding umbrella needs to be opened, the winch handle is rotated. The winch handle drives the ratchet to rotate. The ratchet pushes the limit plate. Under the action of the spring, the limit plate slides into the next meshing tooth of the ratchet, thereby realizing the limit support of the ratchet, preventing the ratchet from reversing, and realizing the self-locking function of the folding umbrella.

[0031] 3. Equipped with a solar panel, ceramic protective plate, cleaning brush, and lever, when the umbrella is folded up, the traction rope drives the second rotating shaft to rotate, which in turn causes the belt to move the cleaning brush and lever. The cleaning brush cleans the surface of the solar panel, and then the lever rotates the solar panel so that the solar panel faces down and the ceramic protective plate faces up, thereby achieving automatic cleaning and protection of the solar panel.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Figure 1-4 As shown, when the base 1 needs to be moved, the screw 6 is rotated, and under the action of the threaded connection, the collar 7 is raised, thereby driving the crank 8 to rotate, causing the end face of the crank 8 to press down, so that the universal wheel contacts the ground, realizing the universal wheel supporting the base 1, thus facilitating the movement of the base 1. When the folding umbrella needs to be used, the winch handle 11 is rotated, and the ratchet 10 pushes the limiting plate 13. Under the action of the spring 14, the limiting plate 13 slides into the next meshing tooth of the ratchet 10, thereby realizing the limiting support of the ratchet 10, preventing the ratchet 10 from reversing, and realizing the self-locking function of the folding umbrella. When the folding umbrella needs to be retracted, the unlocking lever 15 is pressed, so that the limiting plate 13 leaves the ratchet 10, thereby unlocking the ratchet 10 and realizing the reversal of the ratchet 10. After the reversal is completed, the unlocking lever 15 is released, and under the action of the spring 14, the limiting plate 13 is re-engaged into the meshing tooth of the ratchet 10, realizing the locking of the ratchet 10 and realizing the self-locking function of the folding umbrella.

[0046] A vertical pole 16 is fixedly connected to the end face of a horizontal pole 4; a second rotating shaft 18 is rotatably connected to the end face of a traction rope 12, and a belt is connected to the outer side of the second rotating shaft 18 for transmission; a pull rod 31 is fixedly connected to the lower end face of the traction rope 12; an auxiliary frame 33 is rotatably connected to the outer side of the pull rod 31, and multiple auxiliary frames 33 are arranged at equal angles about the axis of the pull rod 31; umbrella ribs 32 are rotatably connected to the outer side of the vertical pole 16, and multiple umbrella ribs 32 are arranged at equal angles about the axis of the vertical pole 16; a hydraulic push rod 19 is rotatably connected to the outer side of the umbrella handle 3. The other end of the hydraulic push rod 19 is rotatably connected to the outer side of the crossbar 4, and two hydraulic push rods 19 are symmetrically arranged about the middle of the umbrella handle 3; the ash collection box 20 is slidably connected to the outer side of the crossbar 4, and two ash collection boxes 20 are symmetrically arranged about the middle of the crossbar 4; the solar panel 21 is rotatably connected to the outer side of the crossbar 4, and a ceramic protective plate 22 is fixedly connected to the lower surface of the solar panel 21, and multiple solar panels 21 are arranged side by side; the cleaning brush 23 is fixedly connected to the inner side of the belt; the lever 24 is fixedly connected to the inner side of the belt, such as Figure 5-7 As shown, when the folding umbrella needs to be used, the winch handle 11 is turned, which drives the traction rope 12 to rotate and retract, thereby raising the position of the pull rod 31 and causing the auxiliary frame 33 to rotate. The auxiliary frame 33 pushes the umbrella ribs 32 to unfold outward, realizing the unfolding of the folding umbrella. Then, the hydraulic push rod 19 can start automatically over time. Under the action of hydraulic pressure, the hydraulic push rod 19 pushes the crossbar 4 to rotate, adjusting the angle between the umbrella handle 3 and the crossbar 4, thereby adjusting the orientation of the folding umbrella and realizing the effect of adjusting the folding umbrella according to the angle of sunlight. At the same time, when using the folding umbrella, the solar panel 21 can convert solar energy into electrical energy to power the folding umbrella. When the folding umbrella is closed, the traction rope 12 drives the second rotating shaft 18 to rotate, thereby causing the belt to drive the cleaning brush 23 and the lever 24 to move. The cleaning brush 23 cleans the surface of the solar panel 21, and then the lever 24 moves the solar panel 21 to rotate, so that the solar panel 21 faces down and the ceramic protective plate 22 faces up. The cleaned dust falls into the dust collection box 20, thereby realizing the automatic cleaning and protection of the solar panel 21.

[0047] A water tank 25 is fixedly connected to the lower surface of the crossbar 4; an atomizing nozzle 27 is fixedly connected to the outer side of the vertical bar 16, and the water tank 25 is fixedly connected to the upper surface of the atomizing nozzle 27 via a water pipe; a gear ring 28 is rotatably connected to the outer side of the vertical bar 16; a gear 29 is meshed with the outer side of the gear ring 28, and a motor is fixedly connected to the shaft end of the gear 29; fan blades 30 are rotatably connected to the outer side of the gear ring 28, and multiple fan blades 30 are arranged at equal angles about the axial direction of the gear ring 28; an air pump 26 is fixedly connected to the outer side of the vertical bar 16; an air outlet 34 is fixedly connected to the end face of the umbrella rib 32; an external buckle 3101 is slidably connected to the lower surface of the pull rod 31, and the external buckle 3101 is made of elastic material, and a mosquito repellent liquid tank 3102, a lighting lamp 3103, and a charging port 3104 are fixedly connected to the lower surface of the external buckle 3101. Figure 8-10 As shown, when cooling is needed inside the folding umbrella, the atomizing nozzle 27 is activated, allowing the water in the water tank 25 to be atomized and sprayed into the folding umbrella. Simultaneously, the motor is activated, and the gear 29 rotates under the motor's drive. Under the meshing action, the gear ring 28 rotates, and under centrifugal force, the fan blades 30 rotate and unfold, blowing air into the folding umbrella and directing the water mist sprayed from the atomizing nozzle 27 into the folding umbrella, thus cooling the interior. At the same time, the air pump 26 is activated, and air is delivered through the umbrella ribs 32 to the air outlet 34, limiting the water mist and preventing it from spreading too much and affecting the cooling effect. In addition, mosquito repellent can be used to repel mosquitoes through the mosquito repellent liquid in the mosquito repellent liquid tank 3102 on the external buckle 3101. The lighting function is provided by the light 3103, and the charging port 3104 can provide external power.

[0048] Working principle: When using this multi-functional folding umbrella that utilizes clean energy, firstly according to... Figure 1-9 As shown, when the folding umbrella needs to be used, rotating the screw 6 causes the crank 8 to drive the universal wheel downwards, supporting the base 1. Then, the base 1 is moved to the usage position. Rotating the winch handle 11 causes the traction rope 12 to rotate and retract, raising the position of the pull rod 31 and causing the auxiliary frame 33 to rotate. The auxiliary frame 33 pushes the umbrella ribs 32 outwards, thus unfolding the folding umbrella. Simultaneously, the limit switch provides support for the ratchet 10, preventing it from reversing and achieving the self-locking function of the folding umbrella. Furthermore, the hydraulic push rod 19 can start and stop itself according to time. The effect of the folding umbrella is adjusted according to the angle of sunlight. At the same time, the atomizing nozzle 27 and the motor are activated. The atomizing nozzle 27 can atomize the water in the water tank 25 and spray it out. Meanwhile, the fan blades 30 can blow the water mist into the folding umbrella. Finally, the air pump 26 is activated, so that air is delivered through the umbrella ribs 32 to the air outlet 34 and sprayed out, thereby limiting the water mist and preventing the water mist from spreading too much and affecting the cooling effect. The mosquito repellent effect can also be achieved through the mosquito repellent liquid in the mosquito repellent liquid tank 3102 on the external buckle 3101. The lighting function is achieved through the light 3103, and the charging port 3104 can achieve the effect of external power supply.
