Description

Technical Field

[0001] The utility model belongs to a vibrating sieve hole atomization system, in particular to an atomization test anti-pollution device. Background Art

[0002] A key component of the vibrating mesh atomization system is the microporous atomizer. This microporous atomizer consists of two layers: an annular piezoelectric ceramic sheet on the bottom layer and a circular metal sheet of the same size on the top layer. The piezoelectric ceramic sheet also has a horizontally extending protrusion on the outer edge for contact with the ejector pin. The circular metal sheet has a micropore located at the center hole of the piezoelectric ceramic sheet.

[0003] Currently, the defective rate of microporous atomizers is high and difficult to detect, directly impacting the yield of atomizer components. Therefore, atomizers require testing for parameters such as atomization rate. Common testing methods involve adding liquid for atomization testing. However, since the added liquid is usually saline, the atomized particles generated by atomization are corrosive and difficult to handle in a cleanroom, potentially affecting other equipment.

[0023] The utility model is a kind of atomization test anti-pollution device as Figure 1-3As shown, it includes a body 1, an atomization detection fixture mounted on the body 1, and an atomization particle filtering device. The atomization particle filtering device includes a mist collection pipe 18 for collecting atomized gas, a sealed gas washing bottle 19, a negative pressure pipe 20, and a negative pressure source 21. One end of the mist collection pipe 18 is connected to the atomization detection fixture, and the other end is connected to the gas washing bottle 19. One end of the negative pressure pipe 20 is provided with a gas filter 22 and is placed in the gas washing bottle 19. The other end is connected to the negative pressure source 21. The gas filter 22 has a membrane that can only pass air, and the atomized particles are retained in the gas washing bottle 19, and are not directly discharged into the environment and cause pollution.

[0024] Please combine Figure 4-Figure 8 As shown, a circular test groove 2 matching the atomizer piece to be tested is provided on the upper end table of the body 1. A mist outlet 3 passing through the table is provided at the bottom of the test groove 2. The atomization detection fixture includes an elastic sealing gasket 4, an elastic sealing ring 5, a pressure plate 6, a liquid storage cavity 7 and a conductive ejector pin 8 arranged in sequence from bottom to top. The annular elastic sealing gasket 4 is provided at the bottom of the test groove 2, and the elastic sealing ring 5 is provided in the annular groove 9 at the bottom of the pressure plate 6. The elastic sealing ring, the gasket 5 and the gasket 4 are used to clamp the atomizer piece to be tested 10, and are pressed into the test groove 2 by the pressure plate 6. The liquid storage cavity 7 is provided on the pressure plate 6 and the bottom water outlet is vertically connected to the central micropores and the mist outlet 3 of the atomizer piece to be tested 10. A pair of conductive ejector pins 8 pass through the pressure plate 6 and are respectively connected to the metal sheet of the atomizer piece 10 to be tested and the protrusion 111 of the piezoelectric ceramic piece.

[0025] The above-mentioned table, the pressing plate 6 of the fixture and the pipeline are all made of transparent anti-corrosion materials, such as transparent PVC, etc., which can facilitate the observation of the atomization situation.

[0026] A positioning notch 11 is provided on the side wall of the test groove 2 , which matches the protrusion 111 of the atomizer chip 10 to be tested, so as to facilitate the installation and positioning of the atomizer chip 10 to be tested.

[0027] The test groove 2 has a circle of bosses 12 at its outer edge, and the bottom of the pressure plate 6 has a first positioning groove 13 that matches the bosses 12. The tabletop has a second groove 14 for the pressure plate 6 to press into, with the test groove 2 located within this second groove 14. Furthermore, a cover plate 15 is hingedly attached to the tabletop to hold the pressure plate 6 in place. This cover plate 15 has a lock hole 16, and a rotating lock 17 that matches the lock hole. The pressure plate 6 can be secured by flipping the cover plate 15 downward and then locked by rotating the lock 17 90 degrees, so that the atomizer 10 is pressed and positioned by the elastic sealing ring and gaskets 5 and 4. A third annular groove 24 is also provided at the bottom of the pressure plate 6, outside the first positioning groove 13. A waterproof sealing ring 241 is embedded within this third groove 24. This waterproof sealing ring 241 encloses the conductive ejector pin 8 at the bottom of the pressure plate 6, preventing the conductive ejector pin 8 from shorting out due to spillage when pouring water into the liquid storage chamber 7.

[0028] The structural dimensions of the above-mentioned atomization detection fixture all adopt the same dimensions as the silicone pad, silicone ring, and ejector pin 8 of the actual atomization component, which can ensure that the force exerted on the microporous atomization sheet 10 in the atomization detection fixture is the same as the force exerted on the actual atomization component, and the installation position is the same, ensuring that the test results are consistent with the actual product effect.

[0029] During use, 3 ml of normal saline is added to the liquid storage cavity 7, and then the atomization controller is connected to the microporous atomization sheet 10 through the ejector pin 8, and the microporous atomization sheet 10 is driven to perform high-frequency vibration, so that normal saline enters the liquid storage cavity 7 and passes through the micropores of the atomization sheet to realize atomization. The atomization controller determines whether atomization is completed by detecting the current during atomization, and records the atomization time, calculates the atomization rate, and then can determine whether the microporous atomization sheet 10 is qualified. In order to improve efficiency, five sets of atomization detection jigs can be combined together and arranged side by side on the body 1. All the mist outlet holes 3 are connected together using a mist collection pipe 18, and the mist generated by the test is opened by a negative pressure source 21 and is pumped into the washing bottle 19 through the mist collection pipe 18. The air is discharged through the gas filter 22, and the atomized particles of normal saline are left in the bottle (condensed into water). If the bottle is full, it can be poured out.

[0030] However, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. Any changes or modifications to the above embodiments shall fall within the scope of the claims of the present invention as long as they are within the spirit of the present invention.
