Claims

1. A cooler with adjustable temperature sensing, comprising: A body includes a housing, the housing having an air inlet channel, a first channel, a flow channel and a second channel, the air inlet channel communicating with the first channel, and the flow channel communicating between the first channel and the second channel. A temperature control switch includes a temperature control structure and an adjustment structure. The temperature control structure is disposed in the housing and includes a temperature sensing unit, a temperature control rod, and a valve connected in series. The temperature sensing unit extends outside the housing. The valve is disposed in the first channel and can block the flow channel. The adjustment structure includes an adjustment member and an elastic member. The adjustment member is movably disposed in the housing relative to the housing, and the elastic member springs against the valve and the adjustment member. A cooling unit is disposed in the second channel and includes a vortex generating part, a cold end, and a hot end. The cold end is connected to an outside of the housing. The vortex generating part is connected between the cold end and the hot end and is connected to the flow channel. The vortex generating part causes the gas from the flow channel to generate a vortex flow to form a cold air flow and a hot air flow. The cold air flow is discharged to the cold end, and the hot air flow is discharged to the hot end. When the temperature sensing unit is affected by temperature changes, the temperature control rod can extend or shorten to move the valve relative to the flow channel, thereby changing the cross-sectional area of ​​the flow channel blocked by the valve; wherein, adjusting the adjusting member causes the adjusting member to move relative to the housing, thereby adjusting the compression of one of the elastic members, and thus adjusting the displacement of one of the valve members.

The adjustable temperature sensing cooler as claimed in claim 1, wherein the housing has an open end communicating with the interior, a first threaded structure is provided on a peripheral wall of the open end, the body further includes a cover, a second threaded structure is provided on a peripheral wall of the cover, the cover covers the open end and the first threaded structure and the second threaded structure are detachably screwed together.

3. The adjustable temperature sensing cooler as claimed in claim 2, further comprising an exhaust device, the body further comprising a spacer, the spacer being detachably disposed within the housing and dividing the housing into a first chamber and a second chamber, the opening end corresponding to the first chamber, the cover and the adjustment structure being located on opposite sides of the spacer, the adjustment structure extending to the second chamber, the exhaust device being disposed on the spacer, and the exhaust device communicating with the hot end and the first chamber.

4. The adjustable temperature sensing cooler as claimed in claim 2, wherein the adjusting member has a control end having a coupling portion that can be engaged by a tool to adjust the adjusting member, the coupling portion facing the cover.

5. The adjustable temperature sensing cooler as claimed in claim 1, wherein the adjustment structure further includes a body detachably locked to and located within the housing, the elastic member being located between the body and the valve member, and the adjustment member being screwed to the body and movable relative to the body.

6. The adjustable temperature sensing cooler as claimed in claim 1, wherein one end edge of the flow channel tapers toward the temperature sensing unit, the valve includes a stop end that tapers toward the flow channel, the stop end having a tapered surface.

7. The adjustable temperature sensing cooler as claimed in claim 6, wherein the stop end is further provided with an airtight ring that can abut against the end edge of the hole.

8. The adjustable temperature sensing cooler as claimed in claim 1, wherein the cold end is tubular and protrudes outward from the body, the cooling unit is further provided with a channel that passes through the eddy current generating part and the cold end, the eddy current generating part has a first opening, the cold end has a second opening, the channel communicates between the first opening and the second opening, and the channel gradually expands from the first opening to the second opening.

9. The adjustable temperature sensing cooler as claimed in claim 1, wherein the housing includes a housing body and a housing base, the housing base being disposed on the housing body, the housing base having the air inlet channel, the first channel, the flow channel and the second channel, the housing base passing through a plurality of return holes, each of the return holes communicating with the housing body and one of the exteriors of the housing body, the adjustable temperature sensing cooler further including a plurality of return pipes, each of the return pipes being detachably disposed on and communicating with a return hole, each of the return pipes protruding from the return hole into the interior of the housing body.

10. The adjustable temperature sensing cooler as claimed in claim 3, wherein the adjusting member has a control end having a connecting portion for a tool to engage and adjust the adjusting member, the connecting portion facing the cover; the adjusting structure further includes a base detachably locked to the housing and located within the housing, the elastic member being located between the base and the valve member, the adjusting member being screwed to the base and movable relative to the base; one end edge of the flow channel tapers toward the temperature sensing unit, the valve member includes a stop end tapers toward the flow channel, the stop end having a tapered surface; the stop end is further provided with an airtight ring that abuts against the end edge of the hole; the cold end is tubular and protrudes outward from the body, the cooling unit is further provided with a channel penetrating the vortex generating part and the cold end, the vortex generating part having a first opening, the cold end having a second opening, the channel communicating with the first opening.
