Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically an air pump. Background Technology

[0002] An air pump, also called an air inflator, tire inflator, or tire pump, works by the operation of a motor. When the motor is running and air is being pumped out, the valve of the inflator is opened by atmospheric pressure, allowing air to enter the cylinder. When air is being pumped into the tire, the valve is closed by the pressure inside the cylinder, allowing air to enter the tire.

[0003] Existing air pumps on the market cannot detect air pressure. They need to be filled with air and then tested with a pressure gauge. If the air pressure is insufficient, air needs to be added. If the air pressure is too high, air needs to be released before testing the air pressure. The operation process is quite cumbersome. Utility Model Content

[0004] This invention provides an air pump to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an air pump, comprising an air pump body, the air pump body including a shell, an air pump assembly disposed inside the shell, the air pump assembly including a motor and a cylinder, an air inflator tube disposed at one end of the top of the cylinder, and a pressure sensor connected to the other end of the cylinder via a pipeline, the end of the air inflator tube away from the cylinder extending into the interior of the shell and provided with an air nozzle and an exhaust button located on one side of the air nozzle.

[0006] Furthermore, a battery connector is provided at one end of the outer casing, a battery pack is movably disposed inside the battery connector, and a two-pronged insert electrically connected to the battery pack is provided inside the battery connector.

[0007] Furthermore, the top of the housing is provided with a handle and a digital display panel located on one side of the handle, and the air pressure sensor is located below the digital display panel.

[0008] Furthermore, an eccentric gear driven by a motor is provided on one side of the bottom of the cylinder, and a piston rod with one end extending into the cylinder is movably provided on one side of the eccentric gear.

[0009] Furthermore, an accessory box is provided at the end of the housing away from the battery connector.

[0010] Furthermore, the accessory box has a plastic air nozzle attached to its internal movable latch.

[0011] Furthermore, the accessory box also contains a valve adapter located above the plastic valve and a metal valve with one end fitted inside the valve adapter.

[0012] Furthermore, an intake check valve is also provided at one end of the top of the cylinder.

[0013] Furthermore, the motor is provided with fan blades at the end away from the cylinder.

[0014] Compared with the prior art, the present invention provides an air pump with the following advantages:

[0015] This air pump is powered by a battery pack, making it more portable. When the valve is connected to the tire, it can simultaneously detect the tire's internal pressure. When the pressure is low, the air pump assembly can be controlled via a digital display to inflate the tire without removing the valve. The pressure sensor monitors the pressure in real time. When the tire's internal pressure is too high, simply press the vent button to release the air from the tire. There is no need to plug or unplug the valve during the process. After adjusting the pressure, simply unplug the valve. This eliminates the need for repeatedly plugging and unplugging the valve to inflate, deflate, and check the pressure, making it much more convenient to use. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This utility model discloses an air pump, including an air pump body 1. The air pump body 1 includes a housing 11. An air pump assembly 12 is disposed inside the housing 11. The air pump assembly 12 includes a motor 121 and a cylinder 122. An air inflator 125 is disposed at one end of the top of the cylinder 122, and a pressure sensor 127 is connected to the other end through a pipeline. The end of the air inflator 125 away from the cylinder 122 extends into the housing 11 and is provided with an air nozzle 128 and an exhaust button 129 located on one side of the air nozzle 128.

[0023] Specifically, a battery connector 15 is provided at one end of the outer casing 11, and a battery pack 16 is movably disposed inside the battery connector 15. A two-pronged insert 151 electrically connected to the battery pack 16 is provided inside the battery connector 15. The battery pack 16 is fixed by a movable snap-fit ​​with the battery connector 15, which makes disassembly and assembly more convenient. It can be used to carry multiple battery packs 16 and can maintain a long battery life.

[0024] Specifically, the top of the housing 11 is provided with a handle 111 and a digital display panel 13 located on one side of the handle 111. The air pressure sensor 127 is located below the digital display panel 13. The digital display panel 13 integrates a switch button for controlling the operation of the air pump assembly 12.

[0025] Specifically, an eccentric gear 123 driven by a motor 121 is provided on one side of the bottom of the cylinder 122. A piston rod 124 extending into the cylinder 122 is movably provided on one side of the eccentric gear 123. An air intake check valve 126 is also provided at one end of the top of the cylinder 122. When the motor 121 is started, the motor 121 drives the eccentric gear 123 to rotate. The eccentric gear 123 drives the piston rod 124 to perform piston movement inside the cylinder 122. Air is drawn in through the air intake check valve 126 and sent into the tire through the inflation pipe 125 and the valve 128.

[0026] Specifically, an accessory box 14 is provided at the end of the outer shell 11 away from the battery connector 15. A plastic air nozzle 141 is movably connected inside the accessory box 14. An air nozzle adapter 142 located above the plastic air nozzle 141 and a metal air nozzle 143 with one end sleeved inside the air nozzle adapter 142 are also movably connected inside the accessory box 14. The plastic air nozzle 141, the air nozzle adapter, and the metal air nozzle 143 can all be connected to the air nozzle 128, which is suitable for inflating different products, such as car tires, two-wheeled and three-wheeled electric vehicles, bicycle tires, or sports equipment such as basketballs. The accessory box 14 makes it more convenient to carry.

[0027] Specifically, the motor 121 is provided with a fan blade 17 at the end away from the cylinder 122.

[0028] In summary, this air pump, powered by the battery pack 16, is more portable. When the valve 128 is connected to the tire, it can simultaneously detect the tire's internal pressure. When the pressure is insufficient, the air pump assembly 12 can be controlled via the digital display board 13 to inflate the tire without removing the valve 128. The air pressure sensor 127 detects the air pressure in real time. When the tire's internal pressure is too high, the air can be released by pressing the vent button 129. There is no need to plug or unplug the valve 128 during this process. After the pressure is adjusted, the valve 128 can be unplugged. This eliminates the need for repeatedly plugging and unplugging the valve 128 to inflate, deflate, and check the pressure, making it more convenient to use.
