Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to an automotive air pump with adaptive air flow adjustment. Background Technology

[0002] An air pump is a common tool mainly used to inflate various inflatable items such as tires, balls, and air mattresses. Air pumps can be divided into manual air pumps and electric air pumps. Manual air pumps require manual operation, which is more laborious but convenient to carry, making them suitable for use outdoors or in situations without power. Electric air pumps, on the other hand, are powered by electricity, inflate quickly, and are easier to use.

[0003] In the existing technology, when an air pump inflates a tire, the amount of air inflated is generally controlled manually. Operational errors or negligence can lead to overinflation, resulting in excessive tire pressure, which affects the tire's service life and may even endanger personal safety. Utility Model Content

[0004] This utility model discloses an auto air pump with adaptive air flow rate adjustment, which aims to solve the technical problem that the air volume of existing air pumps is generally controlled manually when inflating tires, and over-inflation may occur due to operational errors or negligence, resulting in excessive tire pressure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auto air pump with adaptive airflow adjustment includes a housing and an electric motor. A placement ring is fixedly connected to the top of the housing, and an inflation chamber is formed on the inner wall of the placement ring. The inflation chamber has two mounting holes: a first mounting hole and a second mounting hole. An inflation nozzle is fixedly connected to the first mounting hole, and an adjustment chamber is fixedly connected to the second mounting hole. A connecting ring is fixedly connected to one outer wall of the adjustment chamber. An air inlet chamber is fixedly connected to the third mounting hole, and has multiple circumferentially spaced air inlets. A telescopic rod is fixedly connected to one inner wall of the air inlet chamber, extending away from the air inlet. A sliding plate is fixedly connected to one end of the chamber. A spring is wrapped around the outside of the telescopic rod. One end of the spring is fixedly connected to the air inlet chamber, and the other end is fixedly connected to the sliding plate. The interior of the regulating chamber has multiple circumferentially spaced mounting slots. Each mounting slot has an air outlet. Each mounting slot is fixedly connected to a slide rail. Each slide rail is slidably connected to a sliding block. Each sliding block has a mounting platform fixedly connected to one side of its outer wall. Each mounting platform has a connecting rod fixedly connected to one side of its outer wall. The end of each connecting rod away from its corresponding mounting platform is fixedly connected to the sliding plate.

[0007] The system is equipped with an inflation chamber, an adjustment chamber, an air inlet, a sliding plate, a connecting rod, a slide rail, an air outlet, a spring, a telescopic rod, and a sliding block. During inflation, gas enters the inflation chamber through the air inlet, creating a pressure difference between the inside and outside. This causes the sliding plate to stretch the spring and the telescopic rod, allowing gas to enter the adjustment chamber. Simultaneously, the sliding plate, via the connecting rod, drives the sliding block to open the air outlet, allowing gas to enter the inflation chamber and inflate the tire through the inflation nozzle. When the tire approaches the designated pressure, the pressure difference between the inside and outside decreases, and the sliding plate, pulled by the spring, resets, closing the air outlet and the adjustment chamber, thus interrupting inflation and preventing over-inflation that could damage the tire.

[0008] In a preferred embodiment, two springs are fixedly connected to the inner walls of the top and bottom of the outer casing, and the ends of the two springs on the same side away from the outer casing are fixedly connected to the same mounting bracket. The motor is positioned between the two mounting brackets, and the output end of the motor is connected to a fan compartment via a coupling. A filter screen is fixedly connected to the inner wall of the air inlet of the fan compartment, and an air outlet pipe is fixedly connected to the air outlet. A circular hole is provided on the outer casing, and the end of the air outlet pipe away from the fan passes through the circular hole and is fixedly connected to the inner wall of the connecting ring. A handle is fixedly connected to the top of the outer casing, and a mounting hole is provided on the outer casing. A fan is fixedly connected to the mounting hole. A mounting groove is provided on the outer casing, and multiple circular holes are provided in the mounting groove. Springs are fixedly connected to the multiple circular holes, and the ends of the multiple springs away from the corresponding circular holes are fixedly connected to the same filter plate.

[0009] The system is equipped with a fan, spring two, mounting bracket, motor, and spring three. When the internal temperature of the outer shell rises due to prolonged inflation, the fan can cool the interior. When air enters or exits through the filter plate, the filter plate vibrates through spring three, shaking off dust and preventing dust accumulation from affecting air intake, exhaust, and heat dissipation. When the external environment is subjected to vibration or the motor is operating, spring two can reduce the vibration, increase the stability during inflation, and reduce noise.

[0010] As can be seen from the above, the automotive air pump with adaptive air flow adjustment provided by this utility model has the technical effect of eliminating the need for manual control of the air volume when inflating tires, avoiding excessive tire pressure, improving tire lifespan, and ensuring personal safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] The present invention discloses an auto air pump with adaptive air flow adjustment, which is mainly used in scenarios where the air volume of an existing air pump is generally controlled manually when inflating tires. Operational errors or negligence may cause over-inflation, resulting in excessive tire pressure.

[0018] Reference Figures 1-4An adaptive air pump for automobiles includes a housing 1 and a motor 23. A placement ring 2 is fixedly connected to the top of the housing 1, and an inflation chamber 6 is provided on the inner wall of the placement ring 2. The inflation chamber 6 has a first mounting hole and a second mounting hole. An inflation nozzle 8 is fixedly connected to the first mounting hole, and an adjustment chamber 7 is fixedly connected to the second mounting hole. A connecting ring 9 is fixedly connected to one outer wall of the adjustment chamber 7. An air intake chamber 11 is fixedly connected to the third mounting hole, and a plurality of circumferentially spaced air intake holes 10 are provided on the air intake chamber 11. A telescopic rod 17 is fixedly connected to one inner wall of the air intake chamber 11. A sliding plate 12 is fixedly connected to one end of the telescopic rod 17 away from the air intake chamber 11. A spring 16 surrounds the outside of the telescopic rod 17, with one end fixedly connected to the air intake chamber 11 and the other end fixedly connected to the sliding plate 12. The regulating chamber 7 has multiple circumferentially spaced mounting slots, each with an air outlet 15. Each mounting slot is fixedly connected to a slide rail 14, and each slide rail 14 has a sliding block 18 slidably connected to it. Each sliding block 18 has a mounting platform 19 fixedly connected to one outer wall of its side, and each mounting platform 19 has a connecting rod 13 fixedly connected to one outer wall of its side. The end of each connecting rod 13 away from its corresponding mounting platform 19 is fixedly connected to a sliding plate 12. During operation, gas enters the air intake chamber 11 through the air inlet 10, creating a pressure difference that causes the sliding plate 12 to slide along the tension spring 16 and the telescopic rod 17, allowing gas to enter the regulating chamber 7. Simultaneously, the sliding plate 12, via the connecting rod 13, drives the sliding block 18 to slide, opening the air outlet 15 and allowing gas to enter the inflation chamber 6, inflating the tires through the inflation nozzle 8.

[0019] Reference Figure 1 and Figure 4 In a preferred embodiment, two springs 21 are fixedly connected to the inner walls of the top and bottom of the outer casing 1. The ends of the two springs 21 located on the same side, away from the outer casing 1, are fixedly connected to the same mounting bracket 22. A motor 23 is positioned between the two mounting brackets 22. The output end of the motor 23 is connected to a fan housing 26 via a coupling. A filter screen 25 is fixedly connected to the inner wall of the air inlet of the fan housing 26, and an air outlet pipe 4 is fixedly connected to the air outlet. A circular hole is provided on the outer casing 1, through which the end of the air outlet pipe 4 away from the fan passes. A circular hole 1 is fixedly connected to the inner wall of the connecting ring 9. A handle 3 is fixedly connected to the top of the outer shell 1, and a mounting hole 4 is opened on the outer shell 1. A fan 20 is fixedly connected in the mounting hole 4. A mounting groove 2 is opened on the outer shell 1, and multiple circular holes 2 are opened in the mounting groove 2. A spring 3 24 is fixedly connected in the multiple circular holes 2. The end of the multiple spring 3 24 away from the corresponding circular hole 2 is fixedly connected to the same filter plate 5. During the use of the device, the filter plate 5 vibrates through the spring 3 24 to shake off the dust, so as to avoid the accumulation of dust affecting the air intake and exhaust and heat dissipation effect.

[0020] Working principle: When inflating a car tire, gas enters the air intake chamber 11 through the air intake hole 10, creating a pressure difference between the inside and outside. This causes the sliding plate 12 to slide along the tension spring 16 and the telescopic rod 17, allowing gas to enter the regulating chamber 7. Simultaneously, the sliding plate 12 drives the sliding block 18 to slide via the connecting rod 13, opening the air outlet 15 and allowing gas to enter the inflation chamber 6 and inflate the tire through the inflation nozzle 8. When the tire approaches the specified pressure, the pressure difference between the inside and outside decreases, and the sliding plate 12 returns to its original position under the pull of the spring 16, closing the air outlet 15 and the regulating chamber 7, thus interrupting inflation and preventing over-inflation that could damage the tire. When prolonged inflation causes the internal temperature of the outer shell 1 to rise, the fan 20 is activated to cool the interior. When air enters and exits through the filter plate 5, the filter plate 5 vibrates via the spring 24, shaking off dust. When external vibrations occur or the motor 23 vibrates, the spring 21 can mitigate the vibration, increasing the stability of inflation and reducing noise.

[0021] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
