Abstract

The utility model relates to a sieve piece and piezoelectric ultrasonic atomizing piece. This sieve piece is made by the mild metal material of texture, wholly is the spill, a plurality of atomization hole of axial evenly distributed, atomization hole is including not running through the bell mouth that sieves the piece and establishing the through -hole at bell mouth bottom and bell mouth intercommunication. The utility model discloses a solitary sieve piece unit is as the liquid atomization parts, beats the taper hole in sieve piece axial and adds the through -hole as fluid passage, and liquid energy exchange efficiency is high, long service life, the liquid granule that atomizes out is littleer, process the degree of difficulty little, remain seldom.

Description

A kind of sieve and piezoelectric ultrasonic atomization sheet

Technical field

This utility model relates to soniclizer technical field, particularly relates to a kind of sieve and piezoelectric ultrasonic atomization sheet.

Background technology

The effect that liquid is vibrated by piezoelectric ultrasonic atomization sheet, it is possible to be atomized. Existing ultrasonic piezoelectric ultrasonic atomization sheet is attached to piezoelectric ceramics surface by metallic membrane, get through hole in the center certain limit of metallic membrane and pass through path as liquid, metallic membrane is the carrier of piezoelectric ceramics, it is again the path passed through of liquid, is all that the plane vibration mode by piezoelectric ceramic piece drives metallic membrane vibration itself to make the liquid atomization. Metallic membrane is many with rustless steel for material, and owing to energy conversion efficiency is low, stainless steel is hard causes atomizing effect poor, and conversion ratio is low, and the granule being atomized out is big, difficulty of processing big, remain the shortcomings such as serious.

Utility model content

The purpose of this utility model is to provide a kind of sieve overcoming drawbacks described above and piezoelectric ultrasonic atomization sheet.

In first aspect, this utility model provides a kind of sieve. This sieve is made up of the metal material that quality is soft, overall concave, is axially uniformly distributed multiple orifice, and described orifice includes the bellmouth not running through sieve and is located at the through hole connected with bellmouth bottom bellmouth.

Preferably, the degree of depth of described bellmouth is the half of sieve thickness, and the degree of depth of described through hole is the half of sieve thickness.

Preferably, described sieve is made up of platinum material.

Preferably, the thickness of described sieve is 0.1-0.5 millimeter.

In second aspect, this utility model provides a kind of piezoelectric ultrasonic atomization sheet. This atomizing piece includes sieve as described above.

The beneficial effects of the utility model: this utility model adopts an independent sieve unit as liquid atomization member, axially beating taper hole in sieve and add through hole as fluid passage, liquid energy transformation efficiency is high, long service life, the liquid particles being atomized out is less, and difficulty of processing is little, residual is few.

Detailed description of the invention

For the technical scheme making those skilled in the art be better understood from this utility model embodiment, and it is understandable to enable the above-mentioned purpose of this utility model embodiment, feature and advantage to become apparent from, below by drawings and Examples, the technical solution of the utility model is described in further detail. Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

As shown in Fig. 1 to 1A, the sieve 1 of this utility model embodiment is overall concave, and sieve 1 is prepared from by the metal material that quality is soft, and in one embodiment, sieve 1 is made up of platinum material. Sieve 1 be axially uniformly distributed multiple orifice 11, the shape of orifice 11 is visible such as Fig. 2 to 2A.

As shown in Fig. 2 to 2A, the orifice 11 of this utility model embodiment includes the bellmouth 111 not running through sieve and is located at the through hole 112 connected with bellmouth 111 bottom bellmouth 111. The half that the degree of depth is sieve 1 thickness of described bellmouth 111, the half that the degree of depth is sieve 1 thickness of described through hole 112. Wherein, the thickness of sieve 1 is 0.1-0.5 millimeter.

As it is shown on figure 3, the piezoelectric ultrasonic atomization sheet of this utility model embodiment includes sieve 1 as described above, piezoelectric ceramic piece 2 and sheet metal 3. Sheet metal 3 is fixed under piezoelectric ceramic piece 2, and sheet metal 3 is provided with through hole 31, by connecting medium 4, sieve 1 is welded in through hole 31 position at through hole 31 periphery.

This utility model adopts an independent sieve unit as liquid atomization member, axially beats taper hole in sieve and adds through hole as fluid passage, and liquid energy transformation efficiency is high, and long service life, the liquid particles being atomized out is less, and difficulty of processing is little, residual is few.

Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only detailed description of the invention of the present utility model; it is not used to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
