Description
Technical Field
The utility model relates to a quantitative aerosol internal pressure detection auxiliary device, and belongs to the technical field of aerosol detection.
Background
The quantitative aerosol takes a quantitative aerosol valve as a release device, and the content can be quantitatively sprayed out once the aerosol valve is actuated. The quantitative aerosol has one more quantitative chamber than the common aerosol, and the size of the quantitative chamber determines the quantitative dosage of the quantitative aerosol valve. When the quantitative aerosol valve is in a static state, the outer valve is closed to isolate the quantitative chamber of the inner valve from the outside, and at the moment, the quantitative chamber is communicated with the container, and the pressure of a product in the container is larger than the pressure in the quantitative chamber under the action of the propellant vapor pressure due to the pressure drop in the quantitative chamber, so that the content in the container enters and fills the quantitative chamber, and the internal pressure balance is achieved. When the actuator is pressed downwards, the spring in the valve drives the linkage mechanism to close the dosing chamber and isolate the dosing chamber from the inner container. When the actuator continues to move downwards, the external valve system is opened, the quantitative chamber is communicated with the outside through the actuator and the valve rod hole, and at the moment, the high pressure in the quantitative chamber pushes the content out of the valve, so that the quantitative aerosol finishes one-time injection.
The internal pressure of the aerosol is the key for ensuring the normal and safe use of the product, the internal pressure of the product is too high, the explosive safety risk is high, the internal pressure of the product is too low, the use effect is poor, and the product cannot be sprayed out if serious. Before the internal pressure of the aerosol is detected, the actuator is removed, a special connector of the pressure gauge is sleeved into the valve rod to compress, and the indication value of the pressure gauge when the pressure gauge is stable is recorded, so that the internal pressure of the aerosol is obtained.
At present, no quantitative aerosol internal pressure detection device is available, the existing common aerosol internal pressure detection device needs continuous pressure output to accurately detect, the quantitative aerosol is intermittently output, and the once-sprayed quantity cannot realize the quantitative aerosol internal pressure detection. Therefore, the quantitative aerosol product production generally ensures the product quality through the filling amount of the control agent material and the propellant, has no practical reference value, and easily leads to unstable product quality. When quality abnormality occurs in a quantitative aerosol product, the cause of the quality abnormality cannot be analyzed from the internal pressure of the product.
