Detailed Description

Referring to fig. 1 to 4, the present invention provides a piezoceramic atomization sheet structure, including a circular steel sheet 20 and an annular ceramic sheet 10. Wherein, the circular steel sheet 20 is welded and fixed on the bottom surface of the annular ceramic plate 10, the middle part of the circular steel sheet 20 is concave downwards to form a circular flat bottom 21, and a plurality of round holes are uniformly distributed on the circular flat bottom 21.

Be different from current punching part and be the atomizing piece of protruding end, the utility model discloses atomizing piece is sunken downwards with the mid portion of circular steel sheet 20 earlier, forms a circular flat 21, and through punching on circular flat 21 again, can obtain the even and accurate round hole of size that distributes. The round hole can not be deformed and the distance between the round holes can not be changed, thereby ensuring the uniform concentration of the mist, avoiding the situation that part of mist is attached to the mist outlet and simultaneously reducing the requirement on the mist outlet conveying structure.

Preferably, the pads in the atomizing plate structure particularly include a first pad 31 and a second pad 32. The first bonding pad 31 is disposed on the front surface of the annular ceramic plate 10, the second bonding pad 32 includes a first end and a second end, the first end is formed by folding, the first end is fixedly attached to the front surface of the annular ceramic plate 10, the second end is located on the bottom surface of the annular ceramic plate 10, and the first end and the second end are wrapped and clamped on the edge of the annular ceramic plate 10. The first pad 31 forms the positive pole of the atomizing plate and the first end of the second pad 32 forms the negative pole of the atomizing plate. Therefore, the positive electrode and the negative electrode of the atomizing plate are both positioned on the front surface of the annular ceramic plate 10, and compared with the prior art in which the negative electrode is positioned on the circular steel plate 20, the electric conductivity is better. Moreover, the anode and the cathode are positioned on the same side of the annular ceramic plate 10, so that the anode and the cathode are conveniently connected with an external circuit.
