More Information
Summary:This invention relates to an electricity-free blower which comprises a compression airbag, a first one-way valve, at least one flexible pipe, a pulling and pressing component, and a regulation valve. An airtight space is formed in the compression airbag, and the inlet of the compression airbag communicated with the airtight space is provided with the first one-way valve. The flexible pipe is equipped at the outlet of the compression airbag, and the regulation valve is provided on the flexible pipe. A second one-way valve can be further provided between the outlet of the compression airbag and the flexible pipe. By pulling and pressing the pulling and pressing component disposed on top of the compression airbag, the compression airbag can be aerated or deaerated, and the released gas is blown away from the flexible pipe. In addition, the regulation valve is used to regulate and control the gas amount, such that the temperature can be reduced by blowing without consuming any electricity.
