Abstract
The utility model discloses a portable inflator. The portable inflator comprises a cylindrical body with an air flow channel. The cylindrical body is provided with a first one-way valve and a second one-way valve, wherein the air flow channel is divided into a first air cavity and a second air cavity through the first one-way valve and the second one-way valve. The external air is communicated with the first air cavity through the first one-way valve in a one-way mode, and the first air cavity is communicated with the second air cavity through the second one-way valve in a one-way mode. The cylindrical body is further provided with an air compression mechanism enabling the external air to enter the first air cavity through the first one-way valve. The air compression mechanism can be manually driven to work, and the external air enters the second air cavity through the first air cavity after being compressed and then fills a device to be inflated through an air outlet pipe. The portable inflator is simple in structure, small in size and convenient to carry and use.
