[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0025] A method for measuring and inspecting the quantity of household aerosol products, using the volume conversion method, first transferring the content of the aerosol to the density bottle, and using a vacuum pump and an air extraction valve to control the negative pressure of the density bottle during the transfer process: -90kPa ~ -95kPa , and use the injection valve to control the release of the content of the aerosol; then use the relative density method formula: Calculate the mass of the measured aerosol content.
[0026] Due to the internal pressure of aerosol products and the heterogeneity of the contents of the container, and the original shape cannot be maintained in the case of pressure loss, we cannot use conventional methods to detect its volume. In response to this problem, the main goal of this project is to transfer the content of...
