[0029] This embodiment provides an electric inflation device for use in an inflatable device. In this embodiment, the inflatable device is an inflatable tent. Specifically, the electric inflation device presses air into the tent interior through an electric pump, causing the inflatable columns 4 of the tent to expand and support the cover body.

[0030] Please refer to Figures 1 - 4 , the electric inflation device provided in this embodiment includes a pump housing 1, a cover body 2, a power supply device, and a pump assembly 3. Specifically, the main components of the pump assembly 3 include a pump core, a motor, a valve core, a control circuit, an air inlet, and an air outlet. The pump core is used to suck air from the outside and pressurize it, and then transport it to the interior of the inflatable tent through a pipeline. The control circuit is used to control the start, stop, and operating state of the electric pump; the control circuit may include a timer, a pressure sensor, and an automatic shutdown function to prevent over-inflation or long-term operation. The power supply device provides the required power for the electric pump and the control circuit. The air inlet is used to suck in outside air. The air inlet is usually equipped with a filter to prevent dust and debris from entering the pump interior, thereby protecting the internal structure of the pump. The air outlet is used to output pressurized air, and the air is transported to the inflatable tent through a connecting pipeline. The power supply device can be a battery, a vehicle power supply, or a mains power supply, which is selected according to the usage scenario and requirements.

[0031] The pump housing 1 provided in this embodiment defines a receiving cavity 10, and the pump assembly 3 is installed in the receiving cavity 10. The receiving cavity 10 has at least one air outlet adapted to communicate with an inflation channel and at least one air inlet communicating with the outside. The air inlet of the pump assembly 3 communicates with the air inlet, and the air outlet of the pump assembly 3 communicates with the air outlet. The communication here can be a direct connection or a connection through a connecting pipeline. In this way, it is ensured that outside air can smoothly enter the pump assembly 3 and that the pressurized air can be smoothly output to the inflatable device. It is also possible not to have a connection. A reasonable air flow channel is designed in the pump housing 1 so that outside air can enter the inner cavity of the pump housing through the air inlet, and then freely flow to the air inlet of the pump assembly 3. A reasonable air flow channel is designed in the pump housing 1 so that the pressurized air can enter the inner cavity of the pump housing 1 through the air outlet of the pump assembly 3, and then freely flow to the air outlet of the pump housing 1, and finally be transported to the inflatable device. Specifically, air enters the pump housing 1 from the air inlet. When the pump core of the pump assembly 3 operates, the air in the pump housing 1 is sucked in by the pump core, creating a negative pressure at the air inlet of the pump assembly 3, thereby attracting the air flow in the pump housing 1. The pump core of the pump assembly 3 sucks in air and pressurizes it. The pressurized air passes through the air outlet of the pump assembly 3, enters the air outlet of the pump housing 1, and is finally transported to the inflatable device through a pipeline.

[0032] Traditional inflating devices usually require a separate pump assembly 3 to be carried, which increases the burden when going out. The pump housing 1 provided in this embodiment is adapted to be hermetically assembled in the inflation passage of the device to be inflated. In this way, the pump housing 1 is hermetically assembled in the inflation passage of the device to be inflated, ensuring the sealing performance and inflation efficiency between the pump and the device. The pump assembly 3 is integrated into the device to be inflated, and the pump assembly 3 and the device to be inflated are combined into one. When consumers go out, they do not need to carry the pump assembly 3 separately, reducing the number of items to be carried and improving portability and user experience.

[0033] In some embodiments of the present utility model, the accommodating cavity 10 has an open end, and the cover body 2 is arranged at the open end to open or close the open end. In this way, at least part of the components of the pump assembly 3 can enter and exit from the open end for replacement. This means that the user can easily open the cover body 2 to perform maintenance and replacement operations on mechanisms such as the pump core, valve core, and control circuit of the pump assembly 3. The user can replace components such as the pump core, valve core, and control circuit that are easily damaged or worn at any time. This design not only extends the service life of the device but also reduces the downtime of the device caused by component damage. The maintenance process is convenient and efficient. Since key components such as the pump core and control circuit can be easily replaced, the user does not need to purchase a whole new inflating device, but only needs to replace the damaged components, which reduces the maintenance cost and improves the economic benefits of the device. In addition, the user can perform simple repairs and maintenance by themselves, reducing the dependence on professional repair services and improving the user's autonomy and usage experience.

[0034] In some embodiments, the inflation port is arranged on the bottom side or side wall of the pump housing 1, and the air inlet can be arranged on the pump housing independently of the open end. In this embodiment, the air inlet is formed by the gap between the cover body 2 and the open end, as long as it allows air to enter.

[0035] In this embodiment, a one-way valve is arranged at the inflation port to allow air to enter the inflation passage only from the pump assembly, maintaining the pressure stability in the device to be inflated.

[0036] Specifically, the electric inflating device includes a battery 15, the battery 15 is electrically connected to the control circuit and pump core of the pump assembly, the pump housing has a battery compartment 14, the battery compartment 14 has an opening, and the battery 15 is detachably assembled in the battery compartment 14 through the opening. Specifically, the battery 15 is detachably arranged in the battery compartment 14, and a power charging port 151 and a control button 152 are arranged thereon.

[0037] In some embodiments, the cover body 2 is detachably or movably connected to the open end. Exemplarily, the cover body 2 and the open end are fixed by a first fastener 21, and the first fastener 21 includes but is not limited to connection methods such as snap fasteners, screws, and pins.
