## Abstract

An air supply assembly in a spraying device delivers compressed air in an air-sealed delivery path. The assembly includes a concave air output mouth facing the front side, and a nozzle slider having a slider cover on top. The nozzle slider includes a backward-facing slanted surface and an air tube to receive the air. The slider cover includes a peg that extends downward from the bottom. When the slider cover is pushed down, the peg moves down the slanted surface and the nozzle slider moves forward to form an air-sealed contact with an inner side of a center wall of a disk tray to deliver the air to a pod at an outer side of the center wall. When the slider cover moves back up, the peg moves up the slanted surface and the nozzle slider moves backward. The nozzle slider does not rotate when the disk tray rotates horizontally.

## Claims

### Claim 1

An air supply assembly in a spraying device for delivering compressed air to cause a liquid to be sprayed at a spray target, comprising:
a nozzle slider including a concave air output mouth from which the compressed air flows out in a forward direction toward the spray target, a backward-facing slanted surface, a groove at a bottom end of the slanted surface, and an air tube to receive the compressed air;
a slider cover on top of the nozzle slider, a bottom surface of the slider cover including a peg extending downward; and
a spring module attached to a back end of the nozzle slider, the spring module including springs extending in the forward direction, wherein
when the slider cover is pushed down, the peg moves down the slanted surface into the groove and the nozzle slider moves in the forward direction to deliver the compressed air in the forward direction, wherein movement of the nozzle slider in the forward direction causes the springs to compress, and
when the slider cover moves back up, the peg moves up the slanted surface and the springs expand to move the nozzle slider in a backward direction.

### Claim 2 (depends on 1)

The air supply assembly of claim 1, wherein the concave air output mouth is surrounded by a lip elongated sideways.

### Claim 3 (depends on 1)

The air supply assembly of claim 1, further comprising a flexible air pipe attached to a bottom of the nozzle slider to deliver the compressed air from an air source through the nozzle slider, wherein the flexible air pipe bends forward when the nozzle slider moves forward.

### Claim 4 (depends on 1)

The air supply assembly of claim 1, wherein the air supply assembly is part of a disk head which includes a disk lid on top, and wherein when the disk lid closes, the slider cover is pushed down by the disk lid and the nozzle slider is pushed forward by the peg attached to the slider cover.

### Claim 5 (depends on 4)

The air supply assembly of claim 4, wherein the bottom surface of the slider cover further includes vertical springs extending downward, wherein the vertical springs are compressed when the disk lid closes and expand to an original length when the disk lid opens.

### Claim 6 (depends on 1)

The air supply assembly of claim 1, further comprising:
a cylindrical holder having an elongated opening, wherein the nozzle slider is inside the cylindrical holder, and wherein a lip surrounding the concave air output mouth of the nozzle slider fits into the elongated opening.

### Claim 7 (depends on 1)

The air supply assembly of claim 1, wherein the nozzle slider further comprises a stopper attached to a back section of the nozzle slider to stop backward movement of the nozzle slider when the slider cover moves back up.

### Claim 8

A disk head of a spraying device for delivering compressed air to cause a liquid to be sprayed at a spray target, comprising:
a disk tray to carry one or more liquid-containing pods, the disk tray including a center wall that defines a hollow center;
a rotating platform to receive and rotate the disk tray horizontally around a vertical axis that extends through the hollow center of the disk tray; and
an air supply assembly, wherein the air supply assembly comprises:
a nozzle slider including a concave air output mouth from which the compressed air flows out in a forward direction toward the spray target, a backward-facing slanted surface, a groove at a bottom end of the backward-facing slanted surface, and an air tube to receive the compressed air; and
a slider cover on top of the nozzle slider, a bottom surface of the slider cover including a peg extending downward, wherein
when the slider cover is pushed down, the peg moves down the slanted surface into the groove and the nozzle slider moves in the forward direction to form an air-sealed contact with an inner side of the center wall of the disk tray and to deliver the compressed air through an air hole in the center wall to one of the liquid-containing pods, and
when the slider cover moves back up, the peg moves up the slanted surface and the nozzle slider moves in a backward direction, and
wherein the air supply assembly stays stationary when the rotating platform rotates.

### Claim 9 (depends on 8)

The disk head of claim 8, wherein the concave air output mouth is surrounded by a lip elongated sideways.

### Claim 10 (depends on 8)

The disk head of claim 8, further comprising a spring module attached to a back end of the nozzle slider, the spring module including springs extending in the forward direction, wherein the springs are compressed when the nozzle slider moves in the forward direction and expand to move the nozzle slider in the backward direction when the slider cover moves back up.

### Claim 11 (depends on 8)

The disk head of claim 8, further comprising a flexible air pipe attached to a bottom of the nozzle slider to deliver the compressed air from an air source, wherein the flexible air pipe bends forward when the nozzle slider moves forward.

### Claim 12 (depends on 8)

The disk head of claim 8, further comprising:
a disk lid on top of the slider cover, and wherein, when the disk lid closes, the slider cover is pushed down by the disk lid and the nozzle slider is pushed forward by the peg attached to the slider cover.

### Claim 13 (depends on 8)

The disk head of claim 8, wherein the inner side of the center wall of the disk tray includes a sealing rubber layer.

### Claim 14 (depends on 8)

The disk head of claim 8, wherein the disk tray includes a top portion made of a first material and a bottom portion made of a second material different from the first material, the top portion containing the air hole, and the second material is transparent or translucent.

### Claim 15 (depends on 8)

The disk head of claim 8, further comprising:
a stationary sensor module underneath the rotating platform to detect presence of a tab that extends downward and is attached to a bottom-surface position of the rotating platform, wherein the stationary sensor module includes a transmitter on a first side of a notch, and a receiver on a second side of the notch opposite the first side, wherein the stationary sensor module detects the presence of the tab when the tab moves into the notch.

### Claim 16 (depends on 8)

The disk head of claim 8, further comprising a motor module that includes gears and a stationary base, the gears to engage a bottom surface of the rotating platform underneath the disk tray to rotate the rotating platform, and wherein the air supply assembly is on top of the stationary base and remains stationary when the rotating platform rotates.

### Claim 17 (depends on 8)

The disk head of claim 8, wherein the bottom surface of the slider cover further includes vertical springs extending downward, wherein the vertical springs are compressed when the disk lid closes and expand to an original length when the disk lid opens.

### Claim 18 (depends on 8)

The disk head of claim 8, wherein the disk tray includes a plurality of side fins horizontally arranged around the center wall, and between adjacent ones of the side fins is a slot to receive one of the liquid-containing pods.
