Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to an air pump that can be rapidly inflated. Background Technology

[0002] In recent years, cycling has become increasingly popular, and many cyclists enjoy the thrill of speeding through the countryside. To avoid flat tires along the way, they usually carry tire repair kits or spare tires, as well as manual pumps.

[0003] Many tires currently available are tubeless. When using tubeless tires, if the air pressure is insufficient, an air pump can be used to inflate them. However, when a tire is punctured and completely flat, even after repairing the tire with tire repair tools, it cannot be inflated again. Because there is a large gap between the tire and the rim, manual inflation is slow, and the inflation speed is less than the rate of air leakage. As a result, the tire cannot quickly inflate and the edge can not be locked onto the rim to seal the tire. In other words, a tire that has been repaired after a blowout cannot be inflated again and can only be repaired by replacing the tire. If a spare tire is not carried, repair is not possible, and the only option is to go to a repair shop with an air pump, which affects outdoor cycling. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems by proposing a high-expansion air pump.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A high-capacity air pump includes an inflation device. A triangular support base is fixed to the lower end of the inflation device. A transparent air reservoir parallel to the inflation device is fixed to one side of the inflation device via a lower and upper fixed base. The lower end of the lower fixed base is integrally formed with the triangular support base. An air outlet device is fixed to one side of the triangular support base. A connecting channel connecting the inflation device, the transparent air reservoir, and the air outlet device is formed inside the triangular support base. A first one-way valve is installed at the connection between the inner cavity of the inflation device and the connecting channel. An air outlet pipe is installed on the air outlet device, and a mode selection valve is installed on the air outlet pipe. A pressure relief channel communicating with the connecting channel and the external atmosphere is provided on the side wall of the triangular support base. An automatic pressure relief valve is installed in the pressure relief channel. Two pedals are symmetrically hinged to both sides of the triangular support base, and the pedals can rotate 90 degrees.

[0007] Furthermore, the inflation device includes an inflation cylinder, with the lower fixed seat and the upper fixed seat nested outside the two ends of the inflation cylinder, a piston plate slidably installed inside the inflation cylinder, a second one-way valve connecting the two chambers provided on the piston plate, an air inlet opened on the side wall of the inflation cylinder near the upper fixed seat, a third one-way valve installed in the air inlet, a piston rod installed on the side of the piston plate away from the first one-way valve, and a handle installed on the end of the piston rod away from the piston plate.

[0008] Furthermore, an anti-slip cover is detachably attached to the upper surface of the handle.

[0009] Furthermore, a pressure gauge for detecting the internal pressure is fixed to one end of the transparent gas storage cylinder near the upper fixed base.

[0010] Furthermore, the air outlet device includes a connecting air nozzle rotatably mounted on the triangular support base and communicating with the connecting channel, and a clamping cap is provided on the outside of the connecting air nozzle by being threaded onto the triangular support base to fix the air outlet pipe.

[0011] Furthermore, the mode selection valve is a manually operated shut-off valve.

[0012] Furthermore, the upper fixing seat has a tube clamping groove formed on the outer wall of the connection between the inflation device and the transparent air storage cylinder.

[0013] Furthermore, the upper surface of the pedal is formed with anti-slip texture.

[0014] Furthermore, the pedal is a hollow structure with an opening at its lower end face. A sealing cover for sealing the hollow cavity is fixed at the opening at the lower end face of the pedal by a snap fastener or a sliding groove.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] 1. By setting a transparent air tank and a mode selection valve, high-pressure gas can be stored in the transparent air tank in advance, and instantaneous high-flow inflation can be achieved. This effectively overcomes the problem that traditional manual air pumps have slow airflow and are not enough to make the edge of the repaired tire quickly fit and seal with the rim. This significantly improves the success rate of outdoor emergency repairs and avoids the dilemma of having to abandon the trip or find an air pump because the tire cannot be inflated.

[0017] 2. The air pump integrates two modes: direct charging and burst charging, which takes into account both daily air replenishment and emergency air replenishment needs. It is practical and highly adaptable. With a pressure gauge to display the air storage pressure in real time, and equipped with an automatic pressure relief valve, it improves the controllability of operation while ensuring the safety and reliability of the air pump itself.

[0018] 3. The composite stable structure design of the triangular support base and the rotatable pedal significantly improves the overall stability during inflation, overcoming the problems of traditional air pumps being easy to tip over and difficult to operate, making the use process more effortless and safer, and especially suitable for operation requirements in various outdoor environments.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-5 As shown, a high-pressure air pump includes an inflation device 1. A triangular support base 3 is fixed to the lower end of the inflation device 1. A transparent air reservoir 2, parallel to the inflation device 1, is fixed to one side of the inflation device 1 via a lower fixed seat 5 and an upper fixed seat 6. The maximum pressure inside the transparent air reservoir 2 does not exceed 1.0 MPa. The lower end of the lower fixed seat 5 is integrally formed with the triangular support base 3. An air outlet device 4 is fixed to one side of the triangular support base 3. A connecting channel 10 connecting the inflation device 1, the transparent air reservoir 2, and the air outlet device 4 is formed inside the triangular support base 3. A first one-way valve 9 is installed at the connection between the inner cavity of the inflation device 1 and the connecting channel 10. An air outlet pipe 11 is installed on the air outlet device 4. A mode selection valve 12 is installed on the air outlet pipe 11. A pressure relief channel connecting the connecting channel 10 and the external atmosphere is provided on the side wall of the triangular support base 3. An automatic pressure relief valve 13 is installed in the pressure relief channel, and the working pressure of the automatic pressure relief valve 13 is 1.1 MPa. MPa, it can automatically open the pressure relief when the system pressure exceeds the set value, ensuring the safe operation of the air pump and avoiding the risk of overpressure. Two pedals 8 are symmetrically hinged on both sides of the triangular support base 3. The pedals 8 can rotate 90 degrees. The composite stable structure of the triangular support base 3 and the pedals 8 is fixed. By increasing the support area and providing a foot pedal force point, it effectively solves the problem of traditional air pumps being easy to tip over, making the air pump more stable during inflation operation. It not only saves effort but also significantly improves the safety of operation.

[0029] In another preferred embodiment of the present invention, the inflation device 1 includes an inflation cylinder 101, a lower fixed seat 5 and an upper fixed seat 6 respectively nested outside the two ends of the inflation cylinder 101, a piston plate 103 slidably installed inside the inflation cylinder 101, and a second one-way valve 104 connecting the two chambers is provided on the piston plate 103. The second one-way valve 104 allows gas above the piston plate 103 to enter the lower chamber during the evacuation phase, realizing one-way gas flow. An air inlet is opened on the side wall of the inflation cylinder 101 near the upper fixed seat 6, and a third one-way valve 105 is installed in the air inlet. The third one-way valve 105 allows external air to enter the inflation cylinder 101, but prevents internal gas leakage and ensures effective evacuation. A piston rod 102 is installed on the side of the piston plate 103 away from the first one-way valve 9, and a handle 106 is installed on the end of the piston rod 102 away from the piston plate 103.

[0030] As another preferred embodiment of the present invention, an anti-slip cover 107 is detachably connected to the upper surface of the handle 106. The anti-slip cover 107 can increase the friction when holding the hand, improve the comfort and safety of operation, and is detachable for easy replacement or cleaning.

[0031] As another preferred embodiment of the present invention, a pressure gauge 7 for detecting the internal pressure is fixed at one end of the transparent gas cylinder 2 near the upper fixed base 6. The pressure gauge 7 enables the user to monitor the pressure value inside the gas cylinder in real time, accurately judge the gas storage status, avoid the danger of overpressure, and facilitate the control of the timing of the burst charge operation.

[0032] As another preferred embodiment of the present invention, the air outlet device 4 includes a connecting nozzle 41 rotatably mounted on the triangular support base 3 and communicating with the connecting channel 10. The rotatable design of the connecting nozzle 41 facilitates the connection of air tubes at different angles, improving applicability and ease of operation. A clamping cap 42 is provided on the outside of the connecting nozzle 41, which is threadedly mounted on the triangular support base 3 to fix the air outlet tube 11. The clamping cap 42 is threadedly installed and tightly squeezed to ensure the airtightness and reliability of the connection of the air outlet tube 11.

[0033] As another preferred embodiment of the present invention, the mode selection valve 12 is a manually controlled shut-off valve. The manually controlled shut-off valve has a simple structure, is easy to operate, has good sealing performance, and can reliably realize the on / off control of the air circuit and mode switching.

[0034] In another preferred embodiment of the present invention, the upper fixing seat 6 is located at the connection between the inflation device 1 and the transparent air storage cylinder 2, and a tube clamping groove 61 for placing the inflation tube is formed on the outer wall. The tube clamping groove 61 is used to store and fix the unused inflation tube, so as to avoid the tube from being placed randomly and causing entanglement or damage, thereby improving the product's neatness and portability.

[0035] As another preferred embodiment of the present invention, the upper surface of the pedal 8 is formed with anti-slip texture 81. The anti-slip texture 81 can increase the friction between the foot and the pedal surface, prevent the foot from slipping during operation, and further ensure stable force application and safe operation.

[0036] As another preferred embodiment of the present invention, the pedal 8 has a hollow structure with an opening at the lower end face. A sealing cover 82 is installed at the opening at the lower end face of the pedal 8 by means of a snap fastener or a sliding groove to seal the hollow cavity. The hollow structure can reduce the overall weight of the pedal, which is beneficial to reducing the total weight of the air pump. At the same time, its internal cavity can be used to store commonly used tools or accessories. The sealing cover 82 ensures the sealing of the storage space, realizing functional diversification and improved portability.

[0037] The working principle of this utility model is as follows: there are two usage modes. One is the ordinary direct inflation mode, which is suitable for slow inflation. The other is the burst inflation mode, which is suitable for emergency rapid inflation and can quickly build up effective tire pressure to ensure travel safety.

[0038] In direct charging mode, with the mode selection valve 12 in the open position, one end of the inflation hose is installed at the air outlet of the mode selection valve 12, and the other end is connected and fixed to the tire valve. The air pump is placed on the ground, and the two pedals 8 are rotated from a vertical position to a horizontal position. The user steps on the pedals 8 with both feet, using their body weight to press the air pump firmly. After stepping on the pedals 8, the user holds the handle 106 and pulls it up and down. When the piston plate 103 moves upward with the handle 106, a negative pressure is generated in the space below the piston plate 103. Air at the top of 103 enters the space at the bottom of piston plate 103 through the second one-way valve 104. When piston plate 103 moves down with handle 106, air at the bottom of piston plate 103 enters the connecting channel 10 through the first one-way valve 9, and then directly fills the tire through air outlet pipe 11 and mode selection valve 12. At the same time, external air enters the space above piston plate 103 through the third one-way valve 105 under atmospheric pressure. Slow inflation can be achieved by repeatedly pulling handle 106 up and down.

[0039] In the burst charging mode, the mode selection valve 12 is closed. The air pump is placed on the ground, and the two pedals 8 rotate from a vertical to a horizontal position. The user places both feet on the pedals 8 to stabilize the air pump. After pressing the pedals 8, the user holds the handle 106 and pulls it up and down. When the piston plate 103 moves upward with the handle 106, a negative pressure is generated in the space below the piston plate 103. Air at the upper end of the piston plate 103 enters the space at the lower end of the piston plate 103 through the second one-way valve 104. When the piston plate 103 moves downward with the handle 106, air at the lower end of the piston plate 103 enters the connecting channel 10 through the first one-way valve 9 and is then stored in the transparent air reservoir 2. The pressure gauge 7 can be used to observe the air pressure inside the transparent air reservoir 2. Simultaneously, external air, under atmospheric pressure, enters the space above the piston plate 103 through the third one-way valve 105. Pulling the handle 106 up and down slowly increases the air pressure inside the transparent air cylinder 2. After storing sufficient pressurized gas in the transparent air cylinder 2, one end of the inflation hose is installed at the outlet of the mode selection valve 12, and the other end is connected and fixed to the tire valve. Opening the mode selection valve 12 allows the high-pressure gas in the transparent air cylinder 2 to quickly inflate the tire through the outlet hose 11 and the mode selection valve 12, instantly releasing the high-pressure gas and rapidly increasing the tire pressure, thus shortening the inflation time. This method is suitable for situations where the tire leaks severely and ordinary inflation methods are too slow to inflate effectively. When the pressure inside the transparent air cylinder 2 reaches the working pressure of the automatic pressure relief valve 13 during inflation, the automatic pressure relief valve 13 automatically opens to release pressure, expelling excess gas to the atmosphere through the pressure relief channel, preventing damage caused by excessive air pressure inside the transparent air cylinder 2, and ensuring the safety of the air pump and the user.

[0040] Components not described in detail in this article are existing technologies.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
