Abstract

An atomizer for an inhaler includes a housing, a gasket, a liquid absorbing sheet, a wick, and an atomizing element. The housing includes a first housing and a second housing, the first housing and the second housing form a liquid reservoir therebetween for storing liquid. The gasket is sleeved on the first housing, the gasket defines a liquid conducting hole in communication with the liquid reservoir. The liquid absorbing sheet is sleeved on the first housing in contact with the gasket, the liquid absorbing sheet is configured to absorb the liquid in the liquid reservoir via the liquid conducting hole. The wick is in contact with the liquid absorbing sheet and configured to draw the liquid from the liquid absorbing sheet. The atomizing element is fixed to the wick and configured to atomize the liquid in the wick.

First claim

What is claimed is:

1. An atomizer for an inhaler, comprising:
a housing comprising a first housing and a second housing, the first housing being at least partially positioned in the second housing, the first housing defining an air flow passage therein; the first housing and the second housing forming a liquid reservoir therebetween for storing liquid;
a gasket sleeved on the first housing, the gasket defining a liquid conducting hole in communication with the liquid reservoir;
a liquid absorbing sheet sleeved on the first housing in contact with the gasket, the liquid absorbing sheet being configured to absorb the liquid in the liquid reservoir via the liquid conducting hole;
a wick in contact with the liquid absorbing sheet and configured to draw the liquid from the liquid absorbing sheet;
an atomizing element fixed to the wick and configured to atomize the liquid in the wick; and
an atomizing base defining an atomizing cavity, wherein the atomizing base defines an opening at an end thereof and defines a through hole at the other end thereof in communication with the atomizing cavity and an outside of the atomizing base, wherein the wick is located in the atomizing cavity, an edge of the atomizing base having the opening is in contact with the liquid absorbing sheet;
wherein the housing further comprises a third housing formed by an edge of the second housing extending in a direction away from the second housing, the third housing defines a cavity therein, and the gasket and the liquid absorbing sheet are received in the cavity, the liquid absorbing sheet is in contact with an inner wall of the third housing on an edge thereof;
wherein the wick comprises a plurality of fiber filaments, the plurality of fiber filaments located at an end of the wick are separated, at least part of the ends of the plurality of fiber filaments are in contact with the liquid absorbing sheet, the other ends of the plurality of fiber filaments are clamped between the atomizing base and the liquid absorbing sheet.

2. The atomizer for the inhaler according to claim 1 , wherein the number of the liquid conducting hole is plural, and at least one liquid conducting hole has a non-circular shape.

3. The atomizer for the inhaler according to claim 1 , wherein the atomizing base defines a wire through hole thereon; the atomizing element comprises a wire extending through the wire through hole.

4. The atomizer for the inhaler according to claim 1 , wherein at the end of the wick where the plurality of fiber filaments are separated, a length of the fiber filament with ends being in contact with the liquid absorbing sheet is less than a length of the fiber filament with ends being clamped between the atomizing base and the liquid absorbing sheet.

5. The atomizer for the inhaler according to claim 1 , wherein the wick has two ends, each end of the wick is located on opposite sides of the first housing; the atomizing element comprises a heating wire coiled around a middle portion of the wick; the first housing defines an opening in communication with the air flow passage and the atomizing cavity; the through hole is in correspondence with the opening; the heating wire is positioned between the through hole and the opening, and a distance between the heating wire and the first housing is greater than 2 mm.

6. The atomizer for the inhaler according to claim 1 , further comprising a negative electrode connecting element, wherein the negative electrode connecting element comprises a negative electrode connecting element body and a boss located at an outer periphery of the negative electrode connecting element body; the negative electrode connecting element body and the boss are conductors; the negative electrode connecting element body is electrically connected to the boss; the atomizing base is received in the cavity of the third housing; part of the negative electrode connecting element body extends through the cavity and is in contact with the atomizing base; the negative electrode connecting element body is electrically connected to a negative electrode of the atomizing element; the negative electrode connecting element body defines an air inlet in communication with the air flow passage and an outside of the negative electrode connecting element body.
