Background technology
Usual compressed gas temperature is less than indoor temperature, and compressor particularly is placed in into outdoor in the winter time, and compressed gas temperature is low
Yu Shidu, when the compressed gas are used to blow bits in dental oral and dry, allows patient to feel very uncomfortable, clinical demand
Gas temperature is more than 25 DEG C, and usual gas heater volume is big, warm after being exported by one section of pipeline by the gas for heating
Degree very fast decays to low temperature, does not play heating purpose.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is：A kind of gas wink is provided
When heater, the compressed gas that will can be flowed through instantaneously are preheating to predetermined temperature, solve the above problems.
Gas instant heating device described in the utility model, including transit joint, transit joint be provided with conductive pole and
Heater strip support, is equipped with the first conductive spacer and the second conductive spacer, the first conductive spacer and the second conduction on heater strip support
High-resistance electrothermic alloy is provided between pad, conductive metal sheet is provided with heater strip support, conductive metal sheet connection conductive pole and
Second conductive spacer；First conductive spacer is provided with passage, and air inlet is provided with the second conductive spacer on heater strip support
Hole, is provided with gas passage, gas passage connection air admission hole in heater strip support.
When using, compressed gas circulate by the passage of the first conductive spacer along heater strip bracket outer, near the
The air inlet position of two conductive spacer one end enters gas passage, is exported by the gas passage in transit joint, compressed gas circulation
During be fully contacted with high-resistance electrothermic alloy, it is ensured that instantaneous heating effect.
Preferably, connected by spring between conductive metal sheet and the second conductive spacer.
Preferably, high-resistance electrothermic alloy improves the heating effect of compressed gas from as helical form.
Preferably, high-resistance electrothermic alloy is installed in the shape of a spiral on heater strip support, improves the heating effect of compressed gas
Really.
The utility model is had an advantageous effect in that compared with prior art：
Gas instant heating device is reasonable in design, can instantaneously be preheating to predetermined temperature, and volume to the compressed gas for flowing through
It is small, can be built in hand-held apparatus, gas is heated close to outlet side, it is ensured that the minimum heat decay of gas.
