A portable air pump

Abstract

This utility model discloses a portable air pump, including a housing, and an inflating component, a main board, a power storage device, shock-absorbing pads, and a fixing plate disposed within the housing. The inflating component and the power storage device are both electrically connected to the main board. The fixing plate is fixedly connected to the housing, forming a cavity between the fixing plate and the housing. The shock-absorbing pads and the motor portion of the inflating component are both disposed within the cavity. Two shock-absorbing pads are arranged opposite each other on either side of the motor in the inflating component. The fixing plate cooperates with the housing to limit the movement of the inflating component. The shock-absorbing pads reduce the impact of motor vibration on the pump itself and further restrict the inflating component, preventing movement and improving its stability.

Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to a portable air pump. Background Technology

[0002] An air pump typically consists of a motor, cylinder, transmission system, air outlet pipe, and pressure gauge. Its working principle involves the motor drawing in and filling the pump with gas. The motor is the power source for the pump, driving the entire system. The cylinder contains a piston, whose movement compresses and discharges the gas. The transmission system converts the motor's rotational motion into the piston's reciprocating motion. The air outlet pipe delivers the compressed gas to the object to be inflated (such as tires or balloons). The pressure gauge displays the current gas pressure, helping users monitor the inflation status.

[0003] Some existing air pumps have poor stability. When the air pump is working, the high-speed rotation of the motor and the movement of the cylinder and transmission system cause the air pump to vibrate. After working for a long time, it is easy to deviate, which will affect the inflation function and is not conducive to improving the service life of the air pump. Utility Model Content

[0038] like Figure 1-6 The portable air pump shown includes a housing 1, and an inflator 2, a main board 3, a power storage device 4, a shock-absorbing pad 5, and a fixing plate 6 disposed within the housing 1. The inflator 2 and the power storage device 4 are both electrically connected to the main board 3. The fixing plate 6 is fixedly connected to the housing 1, and a cavity is formed between the fixing plate 6 and the housing 1. The shock-absorbing pad 5 and the motor part of the inflator 2 are both disposed within the cavity. There are two shock-absorbing pads 5, which are disposed opposite to each other on both sides of the motor in the inflator 2. It should be noted that the inflatable component 2 is composed of a motor, a transmission system, and a cylinder for inflation. The inflatable component 2 is L-shaped. The shock-absorbing pad 5 is made of plastic. The main board 3 has a charging and discharging interface 31, specifically a USB interface and a Type-C interface, for charging and discharging, enabling the product to function as a power bank. Furthermore, an interface cover 15 is movably installed on the housing 1 to cover and protect the interface. The interface cover 15 can be opened to use the interface. In addition, the side wall of the housing 1 has an air inlet corresponding to the motor for air intake. The inner wall of the housing 1 has multiple studs, and the fixing plate 6 is set on the studs to cooperate with the housing 1 to form a chamber for accommodating the shock-absorbing pad 5 and the inflatable component 2. The two shock-absorbing pads 5 can clamp the motor in the inflatable component 2 to achieve shock absorption, thereby improving the stability of the inflatable component 2 and also reducing noise, which is beneficial to improving the user experience.

[0039] The beneficial effects of this utility model are as follows: the fixing plate 6 cooperates with the shell 1 to limit the inflatable component 2, the shock-absorbing pad 5 can reduce the impact of motor vibration on itself, and can further restrict the inflatable component 2 to prevent the inflatable component 2 from moving, which is conducive to improving the stability of the inflatable component 2.

[0040] Please refer to Figures 4 to 6In one possible implementation, the shock-absorbing pad 5 is provided with a first limiting part 51, which fits against the inflatable component 2. A first limiting groove 52 is provided on the back of the first limiting part 51. Limiting ribs 61 are provided on both the fixing plate 6 and the housing 1, and are respectively inserted into the first limiting grooves 52 on the two shock-absorbing pads 5. It should be noted that the first limiting part 51 can be tightly fitted against the inflatable component 2. Since the two shock-absorbing pads 5 are arranged opposite each other, the first limiting parts 51 on them are also arranged opposite each other to cooperate in clamping the inflatable component 2. By inserting the limiting ribs 61 into the first limiting grooves 52, the shock-absorbing pad 5 is limited, which helps to improve the stability of the shock-absorbing pad 5 and further improves the stability of the inflatable component 2.

[0041] Please refer to Figures 3 to 6 In one possible implementation, the inflatable component 2 is provided with a positioning protrusion 21, the shock-absorbing pad 5 is provided with a second limiting part 53, the positioning protrusion 21 is inserted into the second limiting part 53, the back of the second limiting part 53 is provided with a second limiting groove 54, the fixing plate 6 and the shell 1 are both provided with limiting rings 62, which are respectively inserted into the second limiting grooves 54 on the two shock-absorbing pads 5. It should be noted that the second limiting part 53 is cylindrical, and a groove is provided on the front of the second limiting part 53. The positioning protrusion 21 extends into the groove so that the shock-absorbing pad 5 and the inflatable component 2 can be quickly positioned and installed together. By inserting the limiting ring 62 into the second limiting groove 54, the shock-absorbing pad 5 is further limited, so that the positioning protrusion 21 and the second limiting part 53 fit more tightly. At the same time, it also positions the fixing plate 6, so that the fixing plate 6 and the shock-absorbing pad 5 can fit together quickly. In addition, two positioning protrusions 21 are provided on both sides of the inflatable component 2, and the two positioning protrusions 21 on the same side are located on the two arms of the L-shaped inflatable component 2. Correspondingly, two second limiting parts 53 are provided on one shock-absorbing pad 5, and two limiting rings 62 are also provided on the fixing plate 6 and the shell 1. This design can further improve the stabilizing effect of the shock-absorbing pad 5 and the fixing plate 6 on the inflatable component 2.

It should be noted that the motor needs to be connected to the main board 3 by wires, and the wires can extend through the wire clamping groove 63, which can both guide the wires out of the cavity and fix the wires to prevent them from getting tangled.

[0043] Please refer to Figure 3In one possible implementation, a battery compartment 11 is provided at the center of the housing 1, and the energy storage power supply 4 is disposed inside the battery compartment 11. It should be noted that the battery compartment 11 can fix the energy storage battery. The battery compartment 11 is formed by four baffles arranged in a rectangle.

It should be noted that the air nozzle 12 is used to connect to an external device that needs to be inflated (such as a tire) so that the air generated by the inflator 2 can be smoothly injected into the external device. In addition, the housing 1 is provided with a fixing buckle 18, which is bolted to the housing 1 and is used to fix the air nozzle 12.

[0045] Please refer to Figure 2 and Figure 3 In one possible implementation, the housing 1 is equipped with an emergency jump starter 13, which is electrically connected to the main board 3. It should be noted that the emergency jump starter 13 provides emergency power when the car battery is dead, helping to start the car engine and improving the user experience. Additionally, a power cover 16 is movably mounted on the housing 1 to cover the emergency jump starter 13, providing protection.
