Description

Technical Field

[0001] This invention relates to a foot-operated air pump. Background Technology

[0002] An air pump is a common inflation tool widely used for inflating vehicle tires, air mattresses, balls, and other items. Currently, emergency air pumps on the market are mainly divided into two categories: electric air pumps and manually operated foot-operated air pumps. While electric air pumps offer fast inflation speeds and a high degree of automation, existing products generally suffer from the following problems: insufficient battery life, with a significant discrepancy between advertised parameters and actual usage; low pressure control accuracy, easily leading to over-inflation or under-inflation; and complex user interfaces for some products, making them unfriendly to elderly users unfamiliar with electronic devices. Furthermore, electric air pumps typically require handheld operation or bending over to set up, which remains inconvenient for users with mobility issues. Traditional foot-operated air pumps rely on repeated manual pedaling to generate air pressure. While simple in structure and requiring no power source, they have low inflation efficiency and require significant physical exertion. For the elderly, disabled, and those with weaker constitutions, prolonged continuous pedaling can quickly lead to fatigue, making inflation difficult. Moreover, traditional foot-operated air pumps lack air pressure detection and automatic control functions, and the inflation effect depends entirely on the user's experience and physical strength, making it difficult to meet the inflation needs of car tires and other items that require higher air pressure.

[0003] Therefore, there is a lack of air pump products in the existing technology that can use electricity to achieve automatic inflation, can be started by a simple foot pedal, and are particularly suitable for the elderly, disabled people and other people with inconvenient access to air pumps. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a foot-operated air pump.

[0005] The technical solution of the present invention is: a foot-operated air pump, comprising:

[0006] The housing is configured to be placed on the ground;

[0007] The battery pack, located inside the casing, serves as the power source.

[0008] An air pump is located inside the housing;

[0009] An air line, connected to the air outlet of an air pump, is used to deliver compressed gas to the object to be inflated.

[0010] The foot switch is located on the upper surface of the housing, allowing the user to trigger the inflation operation by touching it with their foot or an object.

[0011] The air pump is connected to an air pump data detection module and an air pump power control module. The air pump data detection module is used to detect the air pressure inside the object to be inflated. When the air pressure is lower than the set value, the air pump power control module automatically starts the air pump to replenish the air. When the air pressure is automatically adjusted to the set value, the air pump stops automatically and maintains the pressure, thus realizing the functions of automatic pressure maintenance and automatic air replenishment.

[0012] Furthermore, the system includes a controller connected to a foot switch, an air pump data detection module, an air pump power control module, a battery pack, a zero-power-outage control circuit for shutdown, a temperature protection control module, a bidirectional USB circuit, an LED light, an LED light switch circuit, and a power and air pressure display module. The battery pack is connected to the air pump, and the air pump is connected to the air pump data detection module and the air pump power control module. The battery pack is also connected to the zero-power-outage control circuit for shutdown and the bidirectional USB circuit.

[0013] Furthermore, the controller includes a voltage detection module connected to the battery pack; a power-on / off management module connected to the power-off zero-power control circuit; a charging monitoring module connected to the battery pack; a temperature detection module connected to the temperature protection control module; a USB control module and a charging control module, both connected to a bidirectional USB circuit; an LED lighting control module connected to an LED light, with the output of the LED light switch circuit connected to the input of the LED lighting control module; and a power and air pressure display control module connected to the power and air pressure display module.

[0014] Furthermore, the battery pack is a titanium battery.

[0015] Furthermore, a panel is located at the top rear end of the housing, which has a switchable air pressure unit. When the air pressure reaches the set value, the foot pump automatically stops inflating and automatically shuts off the power supply to the battery pack.

[0016] Furthermore, multiple air nozzle adapters are detachably fixed to the bottom of the housing by snap-fit, a foot switch plate is located at the front end of the top of the housing, and a charging / discharging port is provided at the rear end of the housing.

[0017] Furthermore, the housing consists of an upper shell and a lower shell, which are distributed vertically. The air nozzle adapter and air line are installed at the bottom of the lower shell, while the panel and foot switch are installed at the top of the upper shell. The rear end of the housing is equipped with a TYPE-C board PCB and a TYPE-C cover for covering the charging and discharging port. There is a shock-absorbing rubber pad between the air pump and the housing. The main board, sensor, and battery pack PCB are also installed inside the housing.

[0018] Furthermore, a foot switch is installed inside the upper end of the housing, located below the foot switch plate, and a spring is installed between the foot switch plate and the upper end of the housing to drive the foot switch plate to reset.

[0019] Furthermore, the surface of the foot switch plate is provided with a flow guide groove.

[0020] The beneficial effects of this invention are:

[0021] It is easy to operate, saves time and effort. Users can start inflation simply by touching the foot switch with their foot or any object. There is no need to bend over or hold the hand. It is especially suitable for the elderly, disabled and people with limited physical strength.

[0022] The air pump data detection module monitors the internal air pressure of the object to be inflated in real time. Combined with the air pump power control module, the air pressure of the object to be inflated can be automatically adjusted according to the set air pressure value. After the set value is reached, the inflation will automatically stop and the battery pack power supply will be turned off to avoid overcharging. It also has an automatic pressure holding function to keep the pressure stable after inflation is completed. When the air pressure is lower than the set value, it will automatically replenish the air.

[0023] Powered by titanium batteries, which are non-flammable and non-explosive, ensuring high safety. A zero-power-consumption control circuit automatically cuts off power during standby or after inflation, significantly reducing power loss. A bidirectional USB circuit supports external charging, allowing the air pump to function as an emergency power source. A temperature protection control module monitors the operating temperature in real time to prevent overheating damage.

[0024] The panel displays information such as current air pressure, set air pressure, and remaining battery power in real time using numbers and icons. The air pressure unit can be freely switched to meet the usage habits of different users.

[0025] Built-in LED light provides illumination at night or in low-light environments, making it convenient for users to connect the valve or check the inflation status, thus improving practicality and safety;

[0026] The bottom of the housing has multiple air nozzle adapters that can be detachably fixed by snap-fit, making them easy to store and less likely to be lost; the foot switch plate has drainage grooves on its surface, which can effectively drain water and prevent slipping, making it safer to use in rainy or humid environments; there is a shock-absorbing rubber pad between the housing and the air pump to reduce operating noise and vibration.

Detailed Implementation

[0040] To provide a more intuitive and complete understanding of the technical solution of this invention, the following non-limiting features are described in conjunction with the accompanying drawings:

[0041] like Figure 1 — Figure 12As shown, a foot-operated air pump includes:

[0042] Housing 1, housing 1 is configured to be placed on the ground;

[0047] The air pump 3 is connected to the air pump data detection module 6 and the air pump power control module 7. The air pump data detection module 6 is used to detect the air pressure inside the object to be inflated. When the air pressure is lower than the set value, the air pump 3 is automatically started by the air pump power control module 7 to replenish the air. When the air pressure is automatically adjusted to the set value, it automatically stops and maintains the pressure, realizing the functions of automatic pressure maintenance and automatic air replenishment.

[0048] The foot-operated air pump includes a controller 8, which is connected to a foot switch 9, an air pump data detection module 6, an air pump power control module 7, a battery pack 2, a power-off zero-power control circuit 10, a temperature protection control module 11, a bidirectional USB circuit 12, an LED light 13, an LED light switch circuit 14, and a power and air pressure display module 15.

[0049] The controller 8 has a voltage detection module 16, which is connected to the battery pack 2; the controller 8 has a power on / off management module 17, which is connected to the power off zero-power control circuit 10; the controller 8 has a charging monitoring module 18, which is connected to the battery pack 2; the controller 8 has a temperature detection module 19, which is connected to the temperature protection control module 11; the controller 8 has a USB control module 20 and a charging control module 21, both of which are connected to the bidirectional USB circuit 12; the controller 8 has an LED lighting control module 22, which is connected to the LED lighting 13, and the output of the LED light switch circuit 14 is connected to the input of the LED lighting control module 22; the controller 8 has a power and air pressure display control module 23, which is connected to the power and air pressure display module 15.

[0050] Battery pack 2 uses titanium batteries. Titanium batteries are not easily flammable or explosive, and are highly safe.

[0051] like Figure 10 As shown, a panel 24 is located at the top rear end of the housing 1. The panel 24 has a switchable air pressure unit. When the air pressure reaches the set value, the foot pump automatically stops inflating and automatically cuts off the power supply to the battery pack 2. The panel 24 displays information such as the current air pressure, set air pressure, and remaining power in real time in the form of numbers and icons. The air pressure unit can be freely switched to meet the usage habits of different users.

[0053] The housing 1 consists of an upper shell 1.1 and a lower shell 1.2, which are distributed vertically. The air nozzle adapter 25 and the air line 4 are both installed at the bottom of the lower shell 1.2, while the panel 24 and the foot switch plate 5 are both installed at the top of the upper shell 1.1.

[0055] like Figure 10 As shown, the foot switch plate 5 has a drainage groove 5.1 on its surface, which can effectively drain water and prevent slipping, making it safer to use in rainy or humid environments.

[0056] This invention is simple to operate, saves time and effort. Users only need to lightly touch the foot switch plate 5 with their foot or any object to start inflation. There is no need to bend over or hold it, making it especially suitable for the elderly, disabled and people with limited physical strength.

[0057] This invention uses the air pump data detection module 6 to monitor the internal air pressure of the object to be inflated in real time. Combined with the air pump power control module 7, it can automatically adjust the air pressure of the object to be inflated according to the set air pressure value. After the air pressure reaches the set value, it automatically stops and turns off the power supply of the battery pack 2 to avoid overcharging.
