## Abstract

An atomizer includes a liquid storage shell, an ultrasonic atomizing core, a liquid transporting cotton, a cooling block, and an end cap. The liquid storage shell surrounds the liquid storage cavity and the functional cavity which are isolated from each other, wherein the liquid storage cavity is used for storing liquid. The ultrasonic atomizing core is assembled in the functional cavity. The liquid transporting cotton is connected to the ultrasonic atomizing core and inserted into the liquid storage cavity, so as to transport the liquid in the liquid storage cavity to the ultrasonic atomizing core. The cooling block is attached on one side of the ultrasonic atomizing core. The cooling block has an atomizing hole and an oil return hole. The end cap is connected to one end of the liquid storage shell to seal the liquid storage cavity and the functional cavity.

## Claims

### Claim 1

An atomizer, comprising:
a liquid storage shell surrounding a liquid storage cavity and a functional cavity which are isolated from each other, wherein the liquid storage cavity is used for storing liquid;
an ultrasonic atomizing core assembled in the functional cavity;
a liquid transporting cotton connected to the ultrasonic atomizing core and inserted into the liquid storage cavity, so as to transport the liquid in the liquid storage cavity to the ultrasonic atomizing core;
a cooling block attached on one side of the ultrasonic atomizing core, wherein the cooling block has an atomizing hole and an oil return hole; and
an end cap connected to one end of the liquid storage shell to seal the liquid storage cavity and the functional cavity, wherein the end cap contacts with and fixes the cooling block, and the end cap has a mist hole;
wherein the liquid is discharged through the atomizing hole and the mist hole in sequence after being atomized.

### Claim 2 (depends on 1)

The atomizer, as recited in claim 1, wherein a diameter of the atomizing hole is 1-5 mm.

### Claim 3 (depends on 1)

The atomizer, as recited in claim 1, wherein a side of the cooling block, which faces the ultrasonic atomizing core, has a limiting groove; the liquid transporting cotton is placed in the limiting groove and opposite ends of the liquid transporting cotton are inserted into the liquid storage cavity; the liquid cotton has a hollow area to avoid blocking the atomizing hole.

### Claim 4 (depends on 1)

The atomizer, as recited in claim 1, wherein
a limiting rib is provided on an internal wall of the functional cavity, and a matching groove is provided on the cooling block; the cooling block contacts with the internal wall of the functional cavity, and the matching groove cooperates with the limiting rib; or
a matching groove is provided on an internal wall of the functional cavity, and a limiting rib is provided on the cooling block; the cooling block contacts with the internal wall of the functional cavity, and the matching groove cooperates with the limiting rib.

### Claim 5 (depends on 1)

The atomizer, as recited in claim 1, further comprising: an insulating sleeve, a conductive rod, a conductive spring, and a thermally conductive silicone grease, wherein an end of the liquid storage shell, which is away from the end cap, has a conductive channel communicating with the functional cavity; the insulating sleeve is under an interference fit state in the conductive channel; the conductive rod passes through the insulating sleeve and is connected to the conductive spring, and the conductive spring is further connected to the ultrasonic atomizing core; the thermally conductive silicone grease is filled between the ultrasonic atomizing core and the conductive rod.

### Claim 6 (depends on 1)

The atomizer, as recited in claim 1, further comprising: a baffle, wherein the baffle is pressed between the end cap and the cooling block, and the baffle has a notch; an orthographic projection of the notch on the end cap does not overlap with the mist hole.

### Claim 7 (depends on 1)

The atomizer, as recited in claim 1, further comprising: an auxiliary shell assembly and a fan, wherein the liquid storage shell has a first air duct communicating with the functional cavity; the auxiliary shell assembly is connected to the liquid storage shell, and has a second air duct communicating with the first air duct; the fan is assembled in the auxiliary shell assembly and faces the second air duct, so as to accelerate air flow in the functional cavity.
