## Abstract

A portable sterilizing sprayer includes a gripper shaped shell, and a nozzle on the front surface of the shell. The back part of the shell includes a clamping device which can be clamped on the waist belt. The inner part of the shell presents a cavity to hold a disinfectant solution. The front end of the shell is provided with a pressing part for pressing the thumb, and when the pressing part is pressed, the disinfection in the liquid storage cavity is carried out. When it is used, it does not need to be removed, and the palm is pressed near the thumb and pressed with the thumb. The disinfecting liquid can be sprayed on the palm of the palm and can be sterilized at any time, so the portable disinfector is convenient to carry and to use it at any time.

## Claims

### Claim 1

A portable sterilizing sprayer comprising:
a housing having a front surface, a back surface and an inner cavity at least partially enclosed by said front and back surfaces, wherein said inner cavity comprises a first chamber configured to be selectively filled with a liquid to be stored therein and a second chamber separated from said first chamber by a partitioning wall;
a nozzle configured to spray or dispense the liquid stored in said first chamber;
a trigger assembly comprising (i) a sleeve disposed at and forming an upper portion of said housing and (ii) an actuating manifold movably disposed within said second chamber and having an internal cavity, said actuating manifold comprising a piston chamber and a discharge conduit both entirely disposed within said internal cavity of said actuating manifold, said discharge conduit is connected in fluid communication with and perpendicularly extending from said piston chamber, wherein said sleeve is connected to said actuating manifold;
a dispensing nozzle assembly disposed within said second chamber, said dispensing nozzle assembly comprising a nozzle member and a connecting pipe extending therefrom, wherein said nozzle member is directly connected with said nozzle, and wherein said connecting pipe is directly connected with said discharge conduit of said actuating manifold; and
wherein said actuating manifold, in response to a force applied to said sleeve, is configured to move from a rest position into a pressed position causing said nozzle to spray or dispense the liquid stored in said first chamber, and wherein said actuating manifold, in response to the force removed from said sleeve, is configured to return to the rest position, and
wherein said sleeve has a pair of opposing sidewalls each including one or more fixed through holes, wherein an inner side of at least said front surface of said housing includes one or more convex pillars, and wherein said housing is connected with said sleeve by said one or more convex pillars being inserted into said one or more fixed through holes of said sleeve.

### Claim 2 (depends on 1)

The portable sterilizing sprayer of claim 1, wherein said piston chamber extends along a linear direction of travel of said actuating manifold.

### Claim 3 (depends on 2)

The portable sterilizing sprayer of claim 2 further comprising a suction pipe assembly extending from said first chamber into said second chamber through an opening fitted with a sealing ring in said partitioning wall.

### Claim 4 (depends on 3)

The portable sterilizing sprayer of claim 3, wherein said suction pipe assembly comprises a tail tube portion disposed at one end of said suction pipe assembly, an elbow tube portion disposed at an opposing end of said suction pipe assembly, and a suction pipe portion disposed therebetween.

### Claim 5 (depends on 4)

The portable sterilizing sprayer of claim 4, wherein said tail tube portion is disposed entirely within said second chamber and said elbow tube portion is disposed entirely within said first chamber.

### Claim 6 (depends on 4)

The portable sterilizing sprayer of claim 4, wherein said tail tube portion of said suction pipe assembly is securely connected in fluid communication with said piston chamber.

### Claim 7 (depends on 1)

The portable sterilizing sprayer of claim 1, wherein said nozzle member is press-fitted into a fixed seat connected to an interior side of said front surface and disposed within said second chamber, such that said nozzle member is generally aligned with said nozzle.

### Claim 8 (depends on 7)

The portable sterilizing sprayer of claim 7, wherein the liquid, in response to said actuating manifold being moved from the rest position into the pressed position, is extruded from said first chamber, via said connecting pipe, to said nozzle member and is ejected from said nozzle member through said nozzle.

### Claim 9 (depends on 7)

The portable sterilizing sprayer of claim 7, wherein one end of said connecting pipe is removably secured to said discharge conduit by a clamp, and wherein another end of said connecting pipe is removably secured to said nozzle member by another clamp.

### Claim 10 (depends on 1)

The portable sterilizing sprayer of claim 1, wherein said back surface comprises a liquid injection aperture for selectively adding the liquid into said first chamber and a cover for plugging or covering said liquid injection aperture.

### Claim 11 (depends on 1)

The portable sterilizing sprayer of claim 1, wherein at least an upper surface of said sleeve comprises a soft rubber material.

### Claim 12 (depends on 1)

The portable sterilizing sprayer of claim 1, wherein said sleeve is fixedly secured to an inner side of said front surface of said housing.

### Claim 13

A portable sterilizing sprayer comprising:
a housing having a front surface, a back surface and an inner cavity at least partially enclosed by said front and back surfaces, wherein said inner cavity comprises a first chamber configured to be selectively filled with a liquid to be stored therein and a second chamber separated from said first chamber by a partitioning wall;

a clamping arm disposed at said back surface of said housing and configured for attachment to an article worn by a user;
wherein said actuating manifold, in response to a force applied thereto, is configured to move from a rest position into a pressed position causing said nozzle to spray or dispense the liquid stored in said first chamber, and wherein said actuating manifold, in response to the force removed therefrom, is configured to return to the rest position, and
a sleeve disposed at an upper portion of said housing, wherein said sleeve is connected to said actuating manifold such that said actuating manifold is configured to be actuated responsive to a force applied to said sleeve, said sleeve has a pair of opposing sidewalls each including one or more fixed through holes, wherein an inner side of at least said front surface of said housing includes one or more convex pillars, and wherein said housing is connected with said sleeve by said one or more convex pillars being inserted into said one or more fixed through holes of said sleeve.
