Description

Technical Field

[0001] The utility model belongs to a vibrating sieve hole atomization system, in particular to an atomization sheet testing 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 atomizer discs in production is high and difficult to detect, directly impacting the yield rate of atomizer components. Furthermore, existing inspection methods are complex and require a high level of expertise, making them unsuitable for use in production. Defective atomizer discs can directly weaken the atomization efficiency of the vibrating mesh atomizer system, reducing the amount of drug inhaled. In severe cases, the vibrating mesh atomizer system can even cease to function. These issues can lead to customer complaints, damage the company's reputation, and increase subsequent operating and maintenance costs. Utility Model Content

[0026] The utility model is a kind of atomization piece testing device as Figure 1-5 As shown, it includes a body 1 and a profiling jig arranged on the body 1.

[0027] On the upper end table of the body 1, there is a circular test groove 2 that matches the atomizer to be tested. A mist outlet 3 is provided at the bottom of the test groove 2 and passes through the table. The imitation 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. 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 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 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 to be tested 10 and the protrusion 111 of the piezoelectric ceramic sheet.

[0028] 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.

[0029] 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.

[0030] The outer edge of the test groove 2 is provided with a circle of bosses 12, and the bottom of the pressure plate 6 has a first positioning groove 13 that matches the bosses 12. The table top has a rectangular second groove 14 for the pressure plate 6 to press into, and the test groove 2 is located within the second groove 14. Furthermore, a cover plate 15 is hingedly attached to the table top to hold down the pressure plate 6. The cover plate 15 has a lock hole 16, and the table top also has a rotating lock 17 that matches the lock hole. The pressure plate 6 can be fixed by flipping down the cover plate 15 and locked by rotating the lock 17 90 degrees, so that the atomizer 10 is pressed and positioned by the elastic sealing ring, gaskets 5 and 4.

[0031] A third annular groove 19 is provided at the bottom of the pressing plate 6 outside the first positioning groove 13. A waterproof sealing ring 191 is embedded in the third groove 19. The waterproof sealing ring 191 encloses the conductive ejector pin 8 at the bottom of the pressing plate 6, thereby preventing the conductive ejector pin 8 from short-circuiting due to spillage when pouring water into the liquid storage chamber 7.

[0032] The structural dimensions of the above-mentioned imitation jig are the same as those of the silicone pad, silicone ring, and ejector pin 8 of the actual atomizer component, which can ensure that the force exerted on the microporous atomizer plate 10 in the imitation jig is the same as that exerted on the actual atomizer component, and the installation position is the same, ensuring that the test results are consistent with the actual product effect.

[0033] When in use, add 3 ml of normal saline to the liquid storage cavity 7, and then connect the atomizer controller to the microporous atomizer sheet 10 through the ejector pin 8, drive the microporous atomizer sheet 10 to vibrate at high frequency, so that the normal saline enters the liquid storage cavity 7 and passes through the micropores of the atomizer sheet to realize atomization. The atomizer controller determines whether the atomization is completed by detecting the current during atomization, and records the atomization time, calculates the atomization rate, and then determines whether the microporous atomizer sheet 10 is qualified. In order to improve efficiency, five sets of imitation jigs can be combined together and arranged side by side on the body 1, and a mist collection pipe 18 is used to connect all the mist outlet holes 3 together and discharge (see Figure 6-7 ).

[0034] 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.
