## Abstract

Present invention teaches a mechanical vaporizer primarily consisting of a mouth piece, an outer tube, and inner tube wrapped by a spring. A heat sink provides the insolation between the outer tube and the heating chamber that contains a side window to show temperature by the length extension of a sensing coil and allows easy removal of used vaping material to be removed.

## Claims

### Claim 1

Mechanical Vaporizer, comprising:
an outer tube;
a mouth piece sized to slidably fit inside a top end of said outer tube;
an inner tube inside said outer tube;
a spring wrapped around said inner tube;
a heat sink connected to said outer tube;
a heating chamber connected to said heat sink, said heating chamber has a sensing coil inside and is viewable through a side window; and
an end disc at a distal end of said inside tube, said end disc further has a filter piece; and
a detachable bottom cap connected to said heating chamber;
wherein said mouth piece has an inner thread portion for attaching to a threaded portion on said inner tube, and
wherein said spring has a top end connected to the mouth piece and a bottom end touching the end disc, providing the resilient force when the mouth piece is pressed inward; and
wherein said sensing coil is anchored inside the heating chamber and will extend its length when heated, causing said side window to show different portions of the coil at different temperatures.

### Claim 2 (depends on 1)

The mechanical vaporizer of claim 1 wherein the heat sink connection to the outer tube is made via one or more O-rings placed over a section of reduced-diameter portion of the heat sink.

### Claim 3 (depends on 2)

The mechanical vaporizer of claim 2 wherein the sensing coil is painted with different colors at different sections.

### Claim 4 (depends on 2)

The mechanical vaporizer of claim 2 wherein the outer tube further having a clip.

### Claim 5 (depends on 2)

The mechanical vaporizer of claim 2, wherein said detachable bottom cap can be pushed off the heating chamber when the mouth piece is pushed down all the way.

### Claim 6 (depends on 2)

The mechanical vaporizer of claim 2, wherein a hinge connects said detachable bottom cap to the heating chamber, allowing said bottom cap to be swung open or close relative to the heating chamber.
