Description

Technical Field

[0001] The present invention relates to the field of ultrasonic atomization, and particularly to a small ultrasonic atomization component. Background Art

[0002] With the development of society and the improvement of human living conditions, more and more people are paying attention to physical health and skin care. Therefore, many related devices have emerged in the market, such as a water replenishing spray device. The water replenishing spray device atomizes liquid water through an ultrasonic atomizer and sprays it in the form of atomized water molecules for facial water replenishment and skin moisturizing. At the same time, the sprayed water mist can also moisten the eyes and relieve eye dryness. However, the existing water replenishing spray devices have the following problems: they can only simply replenish water, and the sprayed water is only water mist. However, for some people with skin inflammation and dry eye, the simple water mist cannot relieve eye dryness and fatigue, reduce inflammation, and relieve the symptoms of dry eye.

[0003] In the prior art, a water replenishing spray device for generating hydrogen water disclosed in Application No. 202022862645X specifically includes a housing, a slide key switch device, an internal bracket, an electrolyzed water device, and a water tank. The housing is fixed on the internal bracket, and a water tank is installed at one end of the housing; a slide key switch device is provided on the housing, and a card slot is provided inside the housing; the slide key switch device includes a push key and a key cap, the protrusion of the push key gear piece is stuck in the groove inside the key cap, and the push key and the key cap are simultaneously installed in the card slot inside the housing; the electrolyzed water device includes an anode electrolysis sheet and a cathode electrolysis sheet; both the anode electrolysis sheet and the cathode electrolysis sheet are fixed at the upper end of the internal bracket; one or more spray ports are arranged from top to bottom on the upper part of the internal bracket, and the atomization of the water mist is realized through the corresponding atomization sheet arranged on the spray port.

[0004] However, in the actual use process, the specific structure of the atomization sheet is not disclosed accordingly, and those skilled in the art do not know the actual structure of the atomization sheet. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a small ultrasonic atomization component: A small ultrasonic atomization component includes a first annular electrode sheet, a ceramic piezoelectric sheet, a second annular electrode sheet, and a microporous filter sheet fixedly connected in sequence. The first annular electrode sheet is electrically connected to a first electrical connection end, the second annular electrode sheet is electrically connected to a second electrical connection end. A micro-hole group is provided in the central area of the microporous filter sheet. The micro-hole group is composed of a plurality of uniformly arranged micro-fine holes. The micro-hole group corresponds to the central hole area provided on the first annular electrode sheet and the second annular electrode sheet. The first electrical connection end and the second electrical connection end are connected to external electric wires. When the first electrical connection end and the second electrical connection end are connected to an external circuit, the ceramic piezoelectric sheet generates ultrasonic vibrations to vibrate the liquid and discharges the generated water mist to the microporous filter sheet.

[0006] Preferably, the first annular electrode sheet is provided with the first electrical connection end and a notch on the surface facing away from the ceramic piezoelectric sheet. A connecting conductive sheet is provided in the notch. There is an insulating gap between the connecting conductive sheet and the first annular electrode sheet and they are insulated from each other. A second electrical connection end is provided on the surface of the connecting conductive sheet corresponding to the first electrical connection end. The connecting conductive sheet is folded in half relative to the ceramic piezoelectric sheet and fixedly connected to the surface of the second annular electrode sheet. The second electrical connection end, the connecting conductive sheet, and the second annular electrode sheet are electrically connected in sequence. Regarding the connection problem between the ultrasonic generator and the filter mesh, if the electric wires are directly welded to the two surfaces of the ultrasonic generating component, since there are raised welding points on the side of the ultrasonic generating component corresponding to the filter sheet, a perfect fit between the ultrasonic generating component and the filter sheet cannot be achieved. Moreover, the two electrical wire connection points will be located on different surfaces, affecting the actual welding application. The connecting conductive sheet and the first annular electrode sheet are insulated from each other. Preferably, the microporous filter sheet is made of titanium metal. If the filter sheet is made of a conventional metal such as a stainless steel thin sheet, it is very easy to be corroded by electrolyzed water and generate rust. The corresponding rust will seriously affect the air ventilation effect of the micro pores and the service life.

[0007] Preferably, the micro pores have an inlet end for water mist to enter and an outlet end for water mist to discharge. An inner concave area corresponding to the central hole is provided at the middle position of the microporous filter sheet. The surface of the inner concave area on the side corresponding to the inlet end is bent inwards. The inner concave area includes an arc-shaped inner concave groove in the middle. The micro hole groups are uniformly arranged on the surface of the arc-shaped inner concave groove.

[0008] Preferably, the inner concave area further includes an annular outer groove surrounding the arc-shaped inner concave groove. The annular outer groove has a funnel-shaped structure with a larger outer diameter and a smaller inner diameter.

[0009] Preferably, the diameter of the micro pores is 5 - 10 microns.

[0010] Beneficial effects: By conducting electricity to the first electrical connection end and the second electrical connection end through an external electric wire, corresponding positive and negative voltages are generated on the two surfaces of the ceramic piezoelectric sheet. When an electric field is applied to the two surfaces of the ceramic piezoelectric sheet, the electric dipoles are deformed under the action of the electric field force, causing the ceramic piezoelectric sheet to generate mechanical expansion and contraction vibrations, resulting in the inverse piezoelectric effect. When the ceramic piezoelectric sheet generates ultrasonic vibrations, since the liquid in contact with the ceramic piezoelectric sheet undergoes atomization, the volume rapidly expands at this time and is discharged through the microporous filter sheet.

Specific embodiments

[0017] The following will further illustrate the present invention in conjunction with the attached Figures 1-5 drawings and embodiments.

[0018] Embodiment: A small ultrasonic atomization assembly includes a first annular electrode sheet 1, a ceramic piezoelectric sheet 2, a second annular electrode sheet 3, and a microporous filter sheet 4 that are fixedly connected in sequence. The fixed connection method can be directly bonded with conductive glue. The microporous filter sheet 4 is made of titanium metal. If the filter sheet is made of a conventional metal such as a stainless steel thin sheet, it is very easy to be corroded by electrolyzed water and generate rust, and the corresponding rust will seriously affect the air ventilation effect of the micro-holes and the service life. Using this material not only ensures the structural stability but also perfectly solves the corrosion problem.

[0019] On the surface of the first annular electrode sheet 1 facing away from the ceramic piezoelectric sheet 2, there are a first electrical connection end 5 and a notch. The first electrical connection end 5 is electrically connected to the first annular electrode sheet 1. A connecting conductive sheet 8 is provided in the notch. There is an insulating gap 9 between the connecting conductive sheet 8 and the first annular electrode sheet 1 and they are insulated from each other. On the side of the connecting conductive sheet 8 corresponding to the first electrical connection end 5, there is a second electrical connection end 6. The first electrical connection end 5 and the second electrical connection end 6 are correspondingly close to facilitate the welding of external wires. The connecting conductive sheet 8 is folded in half relative to the ceramic piezoelectric sheet 2 and fixedly connected to the surface of the second annular electrode sheet 3. The second electrical connection end 6, the connecting conductive sheet 8, and the second annular electrode sheet 3 are electrically connected in sequence.

[0020] Regarding the connection problem between the ultrasonic generator and the filter mesh sheet, if the electric wires are directly welded to the two surfaces of the ultrasonic generating component, since there are raised welding points on the side of the ultrasonic generating component corresponding to the filter sheet, it is impossible to achieve a perfect fit between the ultrasonic generating component and the filter sheet. Moreover, it will also cause the two electric wire connection points to be located on different surfaces, affecting the actual welding application. By adopting the above technical solution, it is possible to avoid the second electrical connection end 6 from affecting the connection between the second annular electrode sheet 3 and the microporous filter sheet 4, and also make the first electrical connection end 5 and the second electrical connection end 6 lie on the same plane, facilitating the welding of the electric wires.

[0021] A micro-hole group 7 is provided in the central region of the microporous filter sheet 4. The micro-hole group 7 is composed of a plurality of uniformly arranged micro-fine holes, and the diameter of the micro-fine holes is 5 - 10 microns. The micro-hole group 7 corresponds to the central hole regions provided on the first annular electrode sheet 1 and the second annular electrode sheet 3. The first electrical connection end 5 and the second electrical connection end 6 are connected to external electric wires. When the first electrical connection end 5 and the second electrical connection end 6 are connected to an external circuit, the ceramic piezoelectric sheet 2 generates ultrasonic vibrations to vibrate the liquid and discharges the generated water mist to the microporous filter sheet 4. The micro-fine holes have an inlet end for the water mist to enter and an outlet end for the water mist to discharge. An inner concave area corresponding to the central hole is provided at the middle position of the microporous filter sheet 4. The surface of the inner concave area on the side corresponding to the inlet end is bent inwards. The inner concave area includes an arc-shaped inner groove 10 in the middle, and the micro-hole group 7 is uniformly arranged on the surface of the arc-shaped inner groove 10. The inner concave area further includes an annular outer groove 11 surrounding the arc-shaped inner groove 10, and the annular outer groove 11 has a funnel-shaped structure with a larger outer diameter and a smaller inner diameter. During the process of the ceramic piezoelectric sheet 2 generating ultrasonic vibrations, the liquid in the inner concave area is rapidly atomized and expanded and is compressed, so as to be quickly discharged from the micro-hole group 7.

[0022] Obviously, the above-mentioned embodiments of the present invention are merely examples for explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
