Description

Technical Field

[0001] This invention relates to the field of power technology, and in particular to a multifunctional outdoor power supply and its usage method. Background Technology

[0002] Outdoor power supplies are devices that store electrical energy, converting between electrical and chemical energy to achieve charging and discharging. When fishing outdoors, various electrical appliances, such as spotlights and electric fans, are often used to make the fishing environment more comfortable. This requires an electrical supply. When the fishing spot is too remote to be powered by the power grid, anglers will use appliances with energy storage capabilities or outdoor power supplies. While existing outdoor power supplies are generally suitable for outdoor environments, they lack specificity for outdoor fishing. Their functions are relatively limited and cannot meet diverse needs, such as oxygen supply, water pumping, mosquito repellency, or massage. In such cases, anglers need to carry corresponding electrical appliances to achieve these functions, resulting in an excessive amount of equipment and causing inconvenience during outdoor fishing, highlighting their shortcomings. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional outdoor power supply and its usage method to solve the above-mentioned technical problems.

The No. 3 shaft is coaxially rotatably connected to a hollow shaft, and a piston is coaxially fixed to its right end. The left side of the hollow shaft is coaxially fixed with a No. 2 gear and a reciprocating screw. The upper part of the lower sliding seat is fixed with a horizontal secondary cylinder, which is slidably and sealingly connected to the piston. A horizontal left inhalation pipe and a left exhaust pipe are fixed, and an electric mosquito repellent device is fixed at the right end. A left one-way valve is fixed to each of the left inhalation pipe and the left exhaust pipe. The outer wall of the auxiliary cylinder is sealed and slidably connected to the main cylinder. A horizontal right inhalation pipe and a right exhaust pipe are fixed to the right end of the main cylinder, and the inner cavity is connected to the right inhalation pipe and the right exhaust pipe. A right one-way valve is fixed to each of the right inhalation pipe and the right exhaust pipe. The main cylinder is fixed to the main housing, and a horizontal support base is fixed to the left rear end. A horizontal transmission arm is inserted into the support base. The transmission arm is fastened to the rear of the support base by a butterfly bolt, and a horizontal transmission rod is fixed to the left front end. The transmission rod is slidably connected to a reciprocating screw. An auxiliary part and a mosquito repellent part are installed on the main housing.

[0005] Based on the above technical solution, the massage part includes a battery, a first axis, a controller, a power interface, foot pedal cranks, foot pedals, a second axis, a reduction gearbox, a DC motor, a first gear, an electric push rod, an upper sliding seat, a third gear, a fourth axis, a fifth axis, a support roller, a sponge sleeve, and a fifth gear. The battery is fixed to the front of the main housing and rotatably connected to the horizontal first axis. The controller is fixed to the front of the battery, and multiple power interfaces are installed at the front of the controller. Foot pedal cranks are fixed to both ends of the first axis, and each of the two foot pedal cranks is rotatably connected to a foot pedal. The rear of the main housing rotates... A horizontal shaft No. 2 is connected, and a reduction gearbox is fixed to its right end. A DC motor is fixed to the right end of the reduction gearbox. A gear No. 1 is coaxially fixed to the left side of the shaft No. 2. A horizontal electric push rod is fixed to the left side of the main housing. A horizontal upper sliding seat is fixed to the rear end of the push rod of the electric push rod. A gear No. 3 is rotatably connected to the upper sliding seat and slides back and forth with the main housing. A horizontal shaft No. 4 and shaft No. 5 are rotatably connected to the upper rear of the main housing. Support rollers are eccentrically fixed to shafts No. 4 and No. 5. A sponge sleeve is fitted onto the outer wall of each support roller. A gear No. 5 is coaxially fixed to the left side of shaft No. 5.

[0006] Based on the above technical solution, the auxiliary part includes a front shell, a rear shell, a baffle, an inflation pipe, an exhaust groove, a maintenance groove, a support plate, a photovoltaic panel, pins, a grounding plug, an adjusting rod, and a buckle plate. The main shell has a front shell fixed to its left and right sides, and a rear shell fixed to its rear. The front and rear shells are respectively fixed with a baffle and an inflation pipe. Each baffle has an exhaust groove penetrating through it. The rear of the main shell has a through maintenance groove, on which a support plate is installed. The photovoltaic panel is fixed to the rear end of the support plate, and a vertical pin is fixed to the bottom of its front end. A vertical grounding plug is hinged to the upper front end of the support plate, and a horizontal adjusting rod is rotatably connected to the upper part. A vertical buckle plate is fixed to the front end of the adjusting rod. The support plate is fastened to the inspection slot by pins and buckles. The shaft of the DC motor is coaxially fixed with the input shaft of the gearbox. The output shaft of the gearbox is coaxially fixed with shaft number two. Shaft number two and shaft number one are connected by a transmission mechanism. Shaft number five and shaft number four are connected by a transmission mechanism. Gear number two meshes with gear number one. When the electric push rod is energized and extends, it can drive the upper sliding seat and gear number three to move back and forth. When moving, gear number three can mesh with gear number five and gear number two at the same time. When moving, gear number three can disengage from gear number five and gear number two. Each of the air inflator pipes is connected to the left discharge pipe through a pipeline.

[0007] Based on the above technical solution, the left one-way valve in the left suction pipe only allows fluid to enter the space formed by the piston and the auxiliary cylinder through the left suction pipe; the left one-way valve in the left discharge pipe only allows fluid to exit the space formed by the piston and the auxiliary cylinder through the left discharge pipe; the right one-way valve in the right suction pipe only allows fluid to enter the space formed by the main cylinder and the auxiliary cylinder through the right suction pipe; and the right one-way valve in the right discharge pipe only allows fluid to exit the space formed by the main cylinder and the auxiliary cylinder through the right discharge pipe. The electric mosquito coil device, battery, controller, DC motor, and electric push rod are electrically connected. When the first shaft rotates, it can drive the second shaft through the transmission mechanism. The second shaft rotates rapidly via a reduction gearbox, causing the DC motor shaft to generate electricity. When the DC motor is energized, the second shaft rotates slowly via the reduction gearbox. The second shaft rotates via gears one and two, causing the hollow shaft to rotate. The hollow shaft rotates via a reciprocating screw, transmission guide rod, transmission arm, and support base, causing the auxiliary cylinder to slide back and forth along the main cylinder and piston. The hollow shaft rotates via gears two, three, and five, causing the fifth shaft to rotate. The fifth shaft rotates via a transmission mechanism, causing the fourth shaft to rotate.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention can replenish the battery with power through foot pedal power generation and photovoltaic power generation, and can also charge the battery to replenish its power. The foot pedal can also relieve leg fatigue caused by prolonged sitting. The rotation of the foot pedal or DC motor can indirectly drive the eccentrically set support roller to rotate, and at the same time drive the secondary cylinder to slide back and forth along the main cylinder and piston. The rotating support roller can provide rolling massage to the buttocks, thereby relieving buttock fatigue caused by prolonged sitting. The reciprocating sliding secondary cylinder can discharge the mosquito repellent gas generated by the electric mosquito coil device through the exhaust channel, thereby targeting mosquitoes and improving the mosquito repellent effect with less influence from external wind. In addition, the reciprocating sliding secondary cylinder can draw in air or water and discharge it through the right exhaust pipe, thereby realizing water supply and oxygenation, which is convenient for storing live fish caught by fishing and improving the survival rate of live fish.

[0019] The auxiliary part 21 includes a front shell 41, a rear shell 42, a baffle 43, an inflation pipe 44, an exhaust channel 45, a maintenance slot 46, a support plate 47, a photovoltaic panel 48, a plug 49, a ground plug 50, an adjustment rod 51, and a buckle 52. The main shell 1 has a front shell 41 fixed to each of its left and right sides, and a rear shell 42 fixed to its rear. The positions of the two front shells 41, in conjunction with the exhaust channel 45 and the electric mosquito repellent device 11, can repel mosquitoes from the angler's legs. The positions of the rear shell 42, in conjunction with the exhaust channel 45 and the electric mosquito repellent device 11, can repel mosquitoes from the angler's buttocks and back. This mosquito repellent is more targeted than traditional mosquito repellent products such as electric mosquito coils and mosquito coils that rely solely on wind power for diffusion. The front housing 41 and rear housing 42 are respectively fixed with baffles 43 and air inlets 44. Each baffle 43 has a through-hole vent 45. The rear of the main housing 1 has a through-hole maintenance slot 46, on which a support plate 47 is installed. A photovoltaic panel 48 is fixed to the rear end of the support plate 47, and a vertical pin 49 is fixed to the bottom front end. A vertical ground plug 50 is hinged to the upper front end of the support plate 47, and the upper part can rotate. A horizontal adjusting rod 51 is connected, and a vertical fastener 52 is fixed to the front end of the adjusting rod 51.

The rotating shaft of the DC motor 31 is coaxially fixed with the input shaft of the gearbox 30, and the output shaft of the gearbox 30 is coaxially fixed with the second shaft 29. The second shaft 29 and the first shaft 24 are connected by a transmission mechanism, which is a known transmission mechanism in the prior art, such as belt drive and gear drive. The fifth shaft 37 and the fourth shaft 36 are connected by... The transmission mechanism is connected to the transmission mechanism, which is a known transmission mechanism in the prior art, such as belt drive and gear drive. The second gear 6 meshes with the first gear 32. When the electric push rod 33 is energized and extends, it can drive the upper sliding seat 34 and the third gear 35 to move back and forth. When the third gear 35 moves, it can mesh with the fifth gear 40 and the second gear 6 at the same time. When the third gear 35 moves, it can disengage from the fifth gear 40 and the second gear 6. Each of the air inflator pipes 44 is connected to the left discharge pipe 10 through a pipe.

[0020] The left one-way valve 12 in the left suction pipe 9 only allows fluid to enter the space formed by the piston 5 and the auxiliary cylinder 8 through the left suction pipe 9. The left one-way valve 12 in the left discharge pipe 10 only allows fluid to exit the space formed by the piston 5 and the auxiliary cylinder 8 through the left discharge pipe 10. The right one-way valve 16 in the right suction pipe 14 only allows fluid to enter the space formed by the main cylinder 13 and the auxiliary cylinder 8 through the right suction pipe 14. The right one-way valve 16 in the right discharge pipe 15 only allows fluid to exit the space formed by the main cylinder 13 and the auxiliary cylinder 8 through the right discharge pipe 15. The electric mosquito coil device 11, the battery 23, the controller 25, the DC motor 31, and the electric push rod 33 are electrically connected. When the first shaft 24 rotates, it can drive the second shaft 29 to rotate through the transmission mechanism. When the second shaft 29 rotates, it can drive the shaft of the DC motor 31 to rotate rapidly through the reduction gearbox 30, thereby enabling the DC motor 31 to generate electricity. When the DC motor 31 is energized and rotates, it can cause the second shaft 29 to rotate slowly through the reduction gearbox 30. When the second shaft 29 rotates, it can drive the hollow shaft 4 to rotate through the first gear 32 and the second gear 6. When the hollow shaft 4 rotates, it can cause the auxiliary cylinder 8 to slide back and forth along the main cylinder 13 and the piston 5 through the reciprocating lead screw 7, the transmission guide rod 20, the transmission arm 18 and the support seat 17. When the hollow shaft 4 rotates, it can drive the fifth shaft 37 to rotate through the second gear 6, the third gear 35 and the fifth gear 40. When the fifth shaft 37 rotates, it can drive the fourth shaft 36 to rotate through the transmission mechanism.

[0021] This invention discloses a method for using a multifunctional outdoor power supply: During use, anglers can sit on the two support rollers 38, using the device as a stool. When anglers become fatigued from prolonged fishing, they can pedal the foot pedals 28 to exercise their legs. The device also drives the second shaft 29 to rotate via the first shaft 24 and transmission mechanism. The rotation of the second shaft 29, through the reduction gearbox 30, causes the DC motor 31 to rotate rapidly, generating electricity which is stored in the battery 23. When in a sunny environment, the adjusting rod 51 can be rotated to release the buckle 52 from the inspection slot 46. Then, the support plate 47 and photovoltaic panel 48 can be removed together. The photovoltaic panel 48 can then be powered by inserting the pins 49 and the ground plug 50 into the soil. The angle is limited to achieve photovoltaic power generation and store the electrical energy in the battery 23. By controlling the extension of the electric push rod 33, the third gear 35 can mesh with the second gear 6 and the fifth gear 40 simultaneously. When the second shaft 29 rotates, it can drive the fourth shaft 36 and the fifth shaft 37 to rotate through the second gear 6, the third gear 35, the fifth gear 40 and the transmission mechanism. This allows the two eccentrically set support rollers 38 to rotate, thereby massaging the buttocks and relieving fatigue caused by prolonged sitting. When the foot pedal 28 becomes tired, the DC motor 31 can be controlled to consume electrical energy to drive the second shaft 29 to rotate slowly. At this time, the electrical energy can be consumed to indirectly drive the fourth shaft 36 and the fifth shaft 37 to rotate, thereby consuming electrical energy to achieve the effect of massaging the buttocks. The massage function targets the buttocks. When shaft 29 rotates, it drives hollow shaft 4 via gears 32 and 6. The rotation of hollow shaft 4, through reciprocating screw 7, transmission rod 20, transmission arm 18, and support seat 17, causes secondary cylinder 8 to slide back and forth along main cylinder 13 and piston 5. During this sliding motion, secondary cylinder 8 draws air from the outside through left one-way valve 12 into the space formed by piston 5 and secondary cylinder 8, then through left discharge pipe 10 and inflation pipe 44 into front housing 41 and rear housing 42, finally exiting through exhaust groove 45. Powering the electric mosquito repellent device 11 at this time allows the mosquito-repelling gas to be released from exhaust groove 45, thus achieving a mosquito-repelling effect. When the mosquito repellent liquid in the electric mosquito repellent device 11 is depleted, further processing is required. When replacing the mosquito repellent liquid, the support plate 47 can be removed, and then the butterfly bolt 19 and the transmission arm 18 can be removed to disconnect the reciprocating sliding connection between the transmission rod 20 and the reciprocating screw 7. Then, the secondary cylinder 8 can be slid to the right to disconnect the sealed sliding connection between the secondary cylinder 8 and the piston 5, thus exposing the piston 5 and allowing the mosquito repellent liquid to be replaced. After that, the transmission arm 18 can be reinstalled to restore the reciprocating sliding connection between the transmission rod 20 and the reciprocating screw 7. When the secondary cylinder 8 reciprocates, the external fluid can be drawn into the space formed by the secondary cylinder 8 and the main cylinder 13 through the right one-way valve 16 and discharged through the right discharge pipe 15. If the fluid drawn is water, it can realize the water supply function. If it is inconvenient to get water at the fishing spot (for example, when the fishing spot is too high), external water can be drawn and stored through an external pipe.This method facilitates the storage of live fish caught during fishing. If the extracted fluid is air, it allows for aeration; if the water containing the fish is oxygen-deficient, air can be introduced to increase oxygen levels, thus improving the survival rate of the fish.
