DIAPHRAGM PUMP, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18301154 Titled 'DIAPHRAGM PUMP, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE APPARATUS'
Simplified Explanation
This abstract describes a diaphragm pump that uses a piezoelectric member to generate movement. When a voltage is applied, the piezoelectric member deforms, causing the diaphragm to also deform. The diaphragm is supported by a supporting member, creating a space between them. By changing the volume of this space through the deformation of the diaphragm, fluid can be made to flow. The diaphragm has two surfaces, one that deforms in response to the piezoelectric member and another surface that is not connected to the first one. The second surface of the diaphragm is bonded to the supporting member.
Original Abstract Submitted
A diaphragm pump includes a piezoelectric member, a diaphragm having surfaces, and a supporting member. The piezoelectric member deforms when a voltage is applied. The diaphragm deforms in response to deformation of the piezoelectric member. The supporting member supports the diaphragm. A space is formed between the diaphragm and the supporting member. Fluid is made to flow by changing a volume of the space by deforming the diaphragm. The surfaces of the diaphragm face the space and include a first surface that deforms in response to deformation of the piezoelectric member and include a second surface not connected to the first surface. The diaphragm bonds to the supporting member with the second surface.
