Abstract
The utility model provides a mist positive pressure protection device of an atomizing granularity analyzer, which belongs to the field of granularity analyzing instruments and structurally comprises a protection cavity, a pipeline and an air source. The protection cavity is provided with an air flow inlet and an air flow outlet, one end of the pipeline is connected with the air flow inlet, and the other end of the pipeline is connected with the air source. When in use, the protection cavity of the protection device is installed on the atomizing granularity analyzer, and the air flow outlet is led to be arranged in a direction right towards a camera lens. Air flows from the air source to the protection cavity through the pipeline, fills the protection cavity and then is discharged to achieve protection for the camera lens and prevent mist from approaching or even clinging to the camera lens. The aerial mist positive pressure protection device is reasonable in design, simple in structure, convenient and practical to use and suitable for being applied to the atomizing granularity analyzer, strengthens protection capability of equipment (particularly the camera lens) on aerial mist and provides effective protection on a light path on the premise that teh volume of the existing instrument is not increased.
Description
(1) technical field
The utility model relates to a kind of sreen analysis instrument, specifically a kind of granularity of spray appearance aerosol positive pressure protection device.
(2) background technology
Present granularity of spray appearance does not have the aerosol protective device, may influence the correctness of experimental data attached on the camera lens after the aerosol ejection.
(3) summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of gas circuit structure is provided, and utilizes air draught aerosol (sample) to be played the granularity of spray appearance aerosol positive pressure protection device of protection and barrier effect.
The utility model solves the technical scheme that its technical matters adopted:
Granularity of spray appearance aerosol positive pressure protection device comprises protection chamber, pipeline and source of the gas, and the protection chamber is provided with airflow inlet and air stream outlet, and an end of pipeline is connected with airflow inlet, and the other end of pipeline is connected with source of the gas.During use; The protection chamber of this device is installed in the granularity of spray appearance and makes air stream outlet be in the direction over against camera lens, and through piping, discharge after arriving the protection chamber and being full of the protection chamber by air-flow from source of the gas for gas; Realization is to the protection of camera lens, avoid aerosol near in addition attached on the camera lens.
Above-mentioned granularity of spray appearance aerosol positive pressure protection device, its source of the gas is a fan blower.
The granularity of spray appearance aerosol positive pressure protection device of the utility model compared with prior art, the beneficial effect that is produced is:
The utility model is reasonable in design, simple in structure, convenient and practical, is applied on the granularity of spray appearance, under the prerequisite that does not increase existing instrument volume, has strengthened the protective capacities of equipment (especially camera lens) for aerosol, to light path effective protection is provided.
(4) description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure, 1, the protection chamber, 2, pipeline, 3, source of the gas, 4, airflow inlet, 5, air stream outlet, 6, camera lens.
(5) embodiment
Below in conjunction with explanation at length below the granularity of spray appearance aerosol positive pressure protection device work of 1 pair of the utility model of accompanying drawing.
Shown in accompanying drawing 1; The granularity of spray appearance aerosol positive pressure protection device of the utility model, its structure comprise protection chamber 1, pipeline 2 and source of the gas 3, and protection chamber 1 is provided with airflow inlet 4 and air stream outlet 5; One end of pipeline 2 is connected with airflow inlet 4, and the other end of pipeline 2 is connected with source of the gas 3.During use, the protection chamber 1 of this device is installed in the granularity of spray appearance and air stream outlet 5 is in over against the direction of camera lens 6, source of the gas 4 (middle drum pressure blower fan) is opened; Air-flow is along arrow direction as shown in the figure; Through piping 2, the internal diameter of pipeline 2 should not be lower than 28mm to continuous flow from source of the gas 3, after air-flow arrives protection chamber 1; Just can evenly be full of protection chamber 1 in a short period of time; The air-flow of continous-stable makes protection chamber 1 continue the indoor malleation that keeps certain, forms certain barotropic field, can effectively stop that at aerosol aerosol arrives camera lens 6 through protecting chamber 1 when camera lens 6 directions are sprayed.
Its processing and fabricating of granularity of spray appearance aerosol positive pressure protection device of the utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
Claims (2)
1. granularity of spray appearance aerosol positive pressure protection device; Comprise protection chamber (1), pipeline (2) and source of the gas (3), it is characterized in that protection chamber (1) is provided with airflow inlet (4) and air stream outlet (5); One end of pipeline (2) is connected with airflow inlet (4), and the other end of pipeline (2) is connected with source of the gas (3).
