Embodiment
Further understand and be familiar with for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Embodiment 1
As shown in Figure 1, a kind of anti-test unit that splashes comprises seal box 1, and the side in sealing case 1 is provided with holder 2, is provided with gatherer 3 below this holder 2; This device also comprises one and seal box 1 opposed jetting system; Jetting system comprises interconnective water tank 4, water pump 5, flow 6 and shower nozzle 7 successively, and this shower nozzle 7 is mutually opposed with a side at seal box 1 interior holder 2 places.
As shown in Figure 2, shower nozzle 7 is for having the spray part of a plurality of spray orifices 8, and the quantity of spray orifice 8 is 12;
The running program of this anti-test unit that splashes is:
A, with 500 (+0/-5) mm is wide, the test agent for the treatment of that 750mm is high is fixed on the holder 2 of seal box 1, guarantees that sample places in the gatherer 3 fully, all must not have obstacle to stop current before or after water impact.
B, current spray to sample 90L at least with the flow velocity of 0.675 (± 0.01) 1/s at horizontal range 500 (± 2) mm place.
C, make water flow in the gatherer 3 by sample and calculate number percent between injection flow rate and the gatherer 3 interior collected water yields.
D, revision test 5 times are calculated the mean value of collected water yield number percent, and discharge number percent mean value is collected in five tests must not be lower than 70% of emitted dose.
If the highest number percent of e collection water and lowest percentage deviation average are more than 5%, then invalidate the test need carry out again.Again be returned in the anomaly average 5% with lowest percentage if the water yield is the highest in test for the second time, but it does not satisfy the described requirement of program d than low value then refusal authentication.
When providing each test findings, the requirement of program d is effective all the time; When the upright position of device when its test findings that obtains is exerted an influence, program a and the described process of program d should be carried out under the highest and minimum collection number percent state again obtaining, and program e stipulates still to come into force.
Fig. 3 shows second embodiment of the anti-test unit that splashes of the utility model, removes jetting system and is different from outside first embodiment, and other structures of the anti-test unit that splashes all are identical, and wherein, jetting system is atomizer 9.
The running program of this anti-test unit that splashes is:
A, the samples vertical of a 305mm * 100mm is fixed in the test unit, guaranteeing does not have the space between sample and the top curved slab, the gatherer location-appropriate.Be full of 1 premium on currency in the aerosol can with sprayer, be placed on position shown in Figure 3; Wherein, sprayer should be adjusted as follows: sprayer pressure: 5bar+10%-0%; Flow velocity: 1L/minute(± 0.5) s; Spray pattern: peripheral jet, the about 50mm of diameter, apart from sample 200mm, nozzle diameter 5mm.
B, injection writing time, make water smoke by sample person who lives in exile gatherer 60s and measure the collected water yield when no water smoke; Measure surplus water in the sprayer, calculate collected water capacity with respect to the number percent of the preceding sprayer volume of spraying.
C, repeat above-mentioned test five times and calculate water collecting amount mean value.Guarantee gatherer, sprayer, measurement vessel drying in each pretest inspection, in test, environment temperature is 21 (± 3) ° C.
The mean value of the water that collect D, five test backs must not be lower than and is ejected into 85% of the water yield on the device;
If the highest number percent of the water that E collects and lowest percentage deviation average are more than 5%, then invalidate the test need carry out again.
If the water yield is the highest in test for the second time is returned to again in the anomaly average 5% with lowest percentage for F, but it does not satisfy the requirement of step D, then refusal authentication than low value.
When the upright position of device when the test findings that obtains is exerted an influence, steps A and the described process of step C should be carried out under high and the minimum collection number percent state again obtaining, but the regulation of program F is still effective.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and the instructions is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
