Description

Technical Field

[0001] This application relates to the technical field of atomization devices, and in particular, to an atomization sheet. Background Art

[0002] With the improvement of people's awareness of respiratory health, atomizers are being widely used. An atomizer breaks up the liquid water molecular structure to produce natural and floating water mist, thereby generating a uniform and delicate fog-like spray, which has great prospects in the medical industry. In the prior art, atomizing a liquid medicine into fine small-particle medicines through an atomizer to complete the inhalation treatment of patients is a conventional treatment method in the intensive care unit (ICU). Among them, the atomization sheet is a very important component in the atomizer, and the atomization sheet is the main factor affecting the atomization effect and the user experience.

[0003] As Figure 1 shown, the existing atomization sheet includes an existing metal sheet 01 and an existing piezoelectric ceramic 02. A plurality of existing atomization fine holes 012 are provided in the atomization area 011 of the existing metal sheet 01. The atomization area 011 bulges upward or depresses downward. The existing piezoelectric ceramic 02 is fixedly connected to one side of the existing metal sheet 01 along the axis direction of the existing metal sheet 01. The existing piezoelectric ceramic 02 is provided with an existing fog outlet 021, and the existing fog outlet 021 corresponds to the atomization area 011.

[0004] When stamping the atomization area, it is first necessary to align the existing metal sheet 01 with the stamping opening of the stamping device, and the operation efficiency is low. During the stamping process, the existing atomization fine holes 012 may become larger, or the stamping position may shift, affecting the fog outlet effect of the atomization sheet. Utility Model Content

[0005] In order to simplify the processing process of the atomization sheet and ensure the fog outlet effect of the atomization sheet, this application provides an atomization sheet.

[0006] The atomization sheet provided by this application adopts the following technical solution:

[0007] An atomization sheet includes a metal sheet, a piezoelectric ceramic, and a PI film. The metal sheet is provided with a spray through hole. The PI film is connected to one side of the metal sheet along the axis direction of the spray through hole and covers the spray through hole. The PI film is provided with a spray area, and the spray area corresponds to the spray through hole. The spray area is evenly distributed with atomization fine holes. The piezoelectric ceramic is connected to the side of the metal sheet close to the PI film. The piezoelectric ceramic is provided with a fog outlet, and the axis of the fog outlet coincides with the axis of the spray through hole.

The metal sheet is provided with a spraying through hole, and the piezoelectric ceramic is provided with a mist outlet. The PI film is fixed by clamping the PI film with the metal sheet and the piezoelectric ceramic, which simplifies the processing process of the atomizing sheet, reduces the possibility of the aperture of the atomizing pores becoming larger during the processing of the metal sheet, and improves the spraying efficiency of the sprayer.

[0009] Preferably, a groove is provided on one side of the metal sheet close to the piezoelectric ceramic. The groove coincides with the axis of the spraying through hole. The PI film is embedded in the groove, the outer wall of the PI film fits against the groove wall, and the piezoelectric ceramic presses against the surface of the PI film away from the bottom of the groove.

[0010] By adopting the above technical solution, the metal sheet is provided with a groove for embedding the PI film, which initially positions the PI film and reduces the possibility of the PI film sliding radially relative to the metal sheet during the connection process between the piezoelectric ceramic and the metal sheet, improving the convenience of installing the atomizing sheet.

[0011] Preferably, the thickness of the PI film is greater than the depth of the groove.

[0012] By adopting the above technical solution, the thickness of the PI film is greater than the depth of the groove, so that when the PI film is placed in the groove, the side of the PI film away from the bottom of the groove extends out of the groove, which helps the piezoelectric ceramic to press against the PI film and reduces the possibility of the PI film sliding axially.

[0013] Preferably, the diameter of the mist outlet is greater than the diameter of the spraying through hole.

[0014] By adopting the above technical solution, the diameter of the mist outlet is greater than the diameter of the spraying through hole, which facilitates the smooth ejection of the water mist generated by the atomizing sheet from the mist outlet and reduces the possibility of the atomizing sheet being blocked.

[0015] Preferably, a welding groove is provided on the outer wall of the piezoelectric ceramic on the side away from the metal sheet, and a welding block is connected to the outer wall of the metal sheet. The welding groove and the welding block are respectively used for connecting the wires connected to the positive and negative poles of the external power supply.

[0016] By adopting the above technical solution, the welding groove and the welding block are provided for connecting with the wires, which facilitates the connection of the wires and the atomizing sheet, improves the stability of the connection between the wires and the atomizing sheet, and improves the service life of the atomizing sheet.

[0017] Preferably, the metal sheet is made of stainless steel.

[0018] By adopting the above technical solution, the metal sheet is made of stainless steel. On the basis of ensuring the electrical conductivity of the metal sheet, the metal sheet has strong corrosion resistance, which helps to improve the service life of the metal sheet and thus improve the service life of the atomizing sheet.

[0019] Preferably, the metal sheet and the piezoelectric ceramic are bonded with glue.

[0020] By adopting the above technical solution, bonding the metal sheet and the piezoelectric ceramic with glue helps the metal sheet and the piezoelectric ceramic to maintain connection during high-frequency vibration, and improves the service life of the atomizing sheet.

[0021] Preferably, a positioning block is connected to the side of the metal sheet close to the piezoelectric ceramic, and the piezoelectric ceramic is provided with a positioning groove for the positioning block to be embedded.

[0022] By adopting the above technical solution, the metal sheet is provided with a positioning block, and the positioning block is embedded in the positioning groove, which helps to align the spray through hole and the mist outlet, and improves the working efficiency of installing the atomizing sheet.

[0023] Preferably, a holding groove is provided on the outer wall of the piezoelectric ceramic on the side away from the metal sheet. There are two holding grooves, and the two holding grooves are located on both sides of the positioning groove along the circumferential direction of the piezoelectric ceramic.

[0024] By adopting the above technical solution, the holding groove is provided to fit the fingers, which improves the stability of the connection between the fingers and the piezoelectric ceramic when the staff takes the piezoelectric ceramic.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. A PI film is provided. The PI film is provided with a spray area, and atomizing fine holes are evenly distributed in the spray area. The metal sheet is provided with a spray through hole, and the piezoelectric ceramic is provided with a mist outlet. The PI film is fixed by clamping the PI film with the metal sheet and the piezoelectric ceramic, which simplifies the processing process of the atomizing sheet, reduces the possibility of the aperture of the atomizing fine holes becoming larger during the processing of the metal sheet, and improves the spraying efficiency of the sprayer;

[0027] 2. The metal sheet is provided with a groove for the PI film to be embedded, which initially positions the PI film and reduces the possibility of the PI film sliding radially relative to the metal sheet during the connection process between the piezoelectric ceramic and the metal sheet, and improves the convenience of installing the atomizing sheet;

[0028] 3. The thickness of the PI film is greater than the depth of the groove. When the PI film is placed in the groove, the side of the PI film away from the bottom of the groove extends out of the groove, which helps the piezoelectric ceramic to press against the PI film and reduces the possibility of the PI film sliding axially.
