Claim 14:
15. An electrostatic sensing assembly, comprising:
a sensing component, configured to be disposed at a fluid distribution component, and the sensing component disposed through the fluid distribution component so as to be partially located in the fluid distribution component; and
a shield, surrounding a part of the sensing component that is located in the fluid distribution component, and at least part of the shield located on an upstream side of the sensing component;
wherein the shield has an opening that is spaced apart from the sensing component;
wherein a fluid inside the fluid distribution component flowing toward the electrostatic sensing assembly is blocked and stopped by the shield, and a flow speed of the fluid is reduced when reaching the sensing component;
wherein the sensing component has a central axis and a circumferential surface surrounding the central axis, the circumferential surface has an outer part and an inner part connected to each other, the outer part is located outside a channel of the fluid distribution component, the inner part is located in the channel of the fluid distribution component, and the shield covers an entire of the inner part of the circumferential surface.
