Temperature conditioning device

Abstract

A temperature conditioning device has a connection tube assembly, a heat exchange unit, a system controller, and a wrap assembly connected to the connection tube assembly. The wrap assembly has a water bag, an air bag and a sleeve wrapped around the air bag and the water bag. The system controller has a water pump for drawing liquid from the heat exchange unit to the water bag to cool or warm a body part of a user, and a pneumatic pump for inflating the air bag to provide holding force. The temperature conditioning device forms a water cycle between the heat exchange unit and the water bag so the water bag is able to keep a cool or warm temperature to comfort a user continuously.

What is claimed is: 
     
         1 . A temperature conditioning device comprising:
 a connection tube assembly having:
 a first water output tube; 
 a second water output tube; and 
 a water input tube; 
   a heat exchange unit having:
 a container; 
 a water exit connector mounted through the container and connected to the first water output tube; and 
 a water return connector mounted through the container and connected to the water input tube; 
   a system controller having a water pump connected to the first water output tube and the second water output tube; and   a wrap assembly having a water bag connected to the second water output tube and the water input tube.   
     
     
         2 . The temperature conditioning device as claimed in  claim 1 , wherein
 the connection tube assembly further has an air input tube;   the system controller further has a pneumatic pump connected to the air input tube; and   the wrap assembly further has
 an air bag overlapping the water bag and connected to the air input tube; and 
 a sleeve wrapped around the air bag and the water bag. 
   
     
     
         3 . The temperature conditioning device as claimed in  claim 2 , wherein the wrap assembly further has an air release valve mounted through the air bag and automatically releasing air overcharged in the air bag. 
     
     
         4 . The temperature conditioning device as claimed in  claim 3 , wherein
 the system controller further has
 a pressure detector; 
 an air guiding tube having two ends respectively connected to the pneumatic pump and the pressure detector; and 
 a solenoid valve electrically connected to and controlled by the pressure detector, and controlling communication between the air guiding tube and the air input tube; and 
   the air input tube is connected to the pneumatic pump via the solenoid valve and the air guiding tube.   
     
     
         5 . The temperature conditioning device as claimed in  claim 4 , wherein the heat exchange unit further has a check valve mounted through the container and allowing air outside the container to flow into the container. 
     
     
         6 . The temperature conditioning device as claimed in  claim 5 , wherein the heat exchange unit further has a pressure limit valve mounted in the water return connector and allowing pressurized liquid to flow into the container. 
     
     
         7 . The temperature conditioning device as claimed in  claim 6  further having a temperature gauge mounted on the second water output tube and the water input tube and disposed adjacent to the wrap assembly. 
     
     
         8 . The temperature conditioning device as claimed in  claim 7  further having a water filter mounted on the first water output tube. 
     
     
         9 . The temperature conditioning device as claimed in  claim 8 , wherein the water exit connector has
 an outer end protruding out of the container and connected to the first water output tube;   an inner end protruding into the container; and   a duct mounted on the inner end of the water exit connector and protruding inward into the container.   
     
     
         10 . The temperature conditioning device as claimed in  claim 9 , wherein
 the container of the heat exchange unit has an opening formed through the container;   the heat exchange unit further has a cap mounted on the container and mounted around the opening of the container; and   the water exit connector, the water return connector and the check valve are mounted through the cap on the container.
