Abstract

An atomizing head baffle includes a first baffle plate and a second baffle plate. A cover plate is disposed on a top of the first baffle plate. The first baffle plate defines first through-holes spaced along a circumferential direction of the first baffle plate. The second baffle plate defines second through-holes spaced along a circumferential direction of the second baffle plate. The second baffle plate is sleeved around an outer periphery of the first baffle plate, thereby reducing areas of the second through-holes to form air holes, and the air holes and the first through-holes are configured to pass through atomized particles. By changing numbers and/or sizes of the first through-holes and the air holes, an atomization amount and an atomization particle size can be changed to meet needs of users without changing other structural parameters or affecting other internal components. This is relatively simple and low cost.

Dependent claims

An atomizing head baffle, configured to be used in a fragrance device and disposed between an atomizing core and a mist outlet of the fragrance device, wherein the atomizing head baffle comprises a first baffle plate and a second baffle plate, the first baffle plate and the second baffle plate are ring-shaped, and a cover plate is disposed on a top of the first baffle plate and is protruding;

the first baffle plate defines first through-holes extending from a lower edge to an upper edge and spaced along a circumferential direction of the first baffle plate, and a number of the first through-holes is at least two;
and the second baffle plate defines second through-holes extending from a lower edge to an upper edge and spaced along a circumferential direction of the second baffle plate, and a number of the second through-holes is at least two;
and wherein the second baffle plate is sleeved around an outer periphery of the first baffle plate with a fixed overlapping distance along a first direction, thereby reducing each cross sectional area of the second through-holes to form air holes, and the air holes and the first through-holes are configured to pass through atomized particles;
and the first direction is a direction oriented from the lower edge of the first baffle plate towards the upper edge of the second baffle plate wherein the first through-holes are spaced from the second through-holes in the first direction, and the lower edge of the second baffle plate is located between the first through-holes and the upper edge of the first baffle plate in the first direction;
and a fragrance diffuser comprising an atomizing head assembly, wherein the atomizing head assembly comprises the atomizing head baffle.
