[0003] At present, the existing vaporizer (such as patent number: CN218721637U) discloses a vaporizer, which increases the contact area between the outer wall of the tank and the external environment by setting a first heat exchange fin assembly on the outer wall of the tank body, thereby improving the heat exchange efficiency. The heat absorbed by the vaporization of the hydrocarbon-based liquid can be supplemented by the external environment.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the liquid fuel was transported into the interior of the equipment through a pipeline, and the function of the closing valve was limited to opening or closing the pipeline, but it was unable to flexibly adjust the delivery flow rate of the liquid fuel according to the actual heating temperature inside the equipment, which may lead to fuel waste.

[0018] The embodiment of the present application provides a micro-vaporizer that can stabilize steam, which effectively solves the problem that liquid fuel is transported into the interior of the device through a pipeline. The function of the closing valve is limited to opening or closing the pipeline, but it is unable to flexibly adjust the delivery flow rate of the liquid fuel according to the actual heating temperature inside the device, which may lead to fuel waste. The micro-metering pump can achieve stable vaporization of liquid feed at a minimum of 0.001 ml / min, and the adjustable flow rate range is also relatively large, with a maximum liquid vaporization rate of 1 ml / min, which destroys the surface tension of the liquid and disperses the liquid into a liquid film with a thickness of microns inside the structure, thereby increasing the evaporation surface area and accurately controlling the flow rate of the liquid.

[0019] Example

[0020] like Figure 1 , Figure 2 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the liquid fuel is transported into the interior of the device through the pipeline, and the function of the closing valve is limited to opening or closing the pipeline, but cannot flexibly adjust the delivery flow rate of the liquid fuel according to the actual heating temperature inside the device, which may lead to the waste of fuel. The overall idea is as follows:

[0021] In view of the problems existing in the prior art, the utility model provides a trace vaporizer capable of stabilizing steam, comprising an outer shell 1, a vaporization module being installed inside the outer shell 1, the vaporization module comprising a first stainless steel tube 12 and a heating rod 18, an aluminum rod 13 being arranged inside the outer shell 1, a thermocouple 14 being fixedly installed at the top end of the aluminum rod 13, the interior of the thermocouple 14 being formed into a loop by connecting two ends of two conductors of different components, when the temperatures of the two junctions are different, a thermoelectric potential will be generated in the loop, and the temperature difference between the two junctions can be obtained by measuring the magnitude of the thermoelectric potential, thereby determining the temperature of the measuring point, and then the temperature detected by the thermocouple 14 is transmitted to the outside through the second stainless steel tube 23, a spacer nut 15 is arranged at the bottom end of the aluminum rod 13, and a second stainless steel tube 23 is fixedly installed at the top end of the first stainless steel tube 12.

[0022] An upper end cover 21 is fixedly installed on the top end of the shell 1, and a lower end cover 11 is fixedly installed on the bottom end of the shell 1. A ferrule joint 17 is provided at the bottom end of the lower end cover 11, and a fixing screw 16 is provided inside the lower end cover 11. A fastening nail 19 is provided at the side end of the heating rod 18. Electricity is transmitted to the inside of the heating rod 18 through a cable 24, so that the heating rod 18 can heat up quickly, and the heating rod 18 heats the liquid. At the same time, a fastening nail 19 is installed on the side end of the heating rod 18, and the fastening nail 19 is used to fix the position of the heating rod 18. An aviation joint 22 is fixedly installed on the side end of the shell 1, and at least two cables 24 are provided inside the aviation joint 22.

[0023] Working principle:

[0024] In the first step, first, an aviation joint 22 is installed at the top of the shell 1, and at least two second stainless steel tubes 23 are installed inside the aviation joint 22. The ends of the second stainless steel tubes 23 are respectively connected to the tops of the heating rod 18 and the thermocouple 14. The liquid to be vaporized enters the shell 1 through the feed pipe, and the power is transmitted to the inside of the heating rod 18 through the cable 24, so that the heating rod 18 heats up quickly. The heating rod 18 heats the liquid. At the same time, a fastening nail 19 is installed at the side end of the heating rod 18. The fastening nail 19 is used to fix the position of the heating rod 18. At the same time, a thermocouple 14 is installed at the top of the aluminum rod 13. One end of the thermocouple 14 is connected to the second stainless steel tube 2 3 connection, the interior of the thermocouple 14 is composed of two conductors of different components connected at both ends to form a loop. When the temperatures of the two junctions are different, a thermoelectric potential will be generated in the loop. By measuring the size of the thermoelectric potential, the temperature difference between the two junctions can be obtained, thereby determining the temperature of the measuring point, and then the temperature detected by the thermocouple 14 is transmitted to the outside through the cable 24. The temperature detected by the thermocouple 14 is used to heat the vaporizer temperature to a suitable vaporization temperature with a temperature control instrument, and then the liquid is pumped in with a micro-metering pump. When the liquid obtains enough heat, its molecules overcome the cohesive force of the liquid surface and escape from the liquid surface, thereby realizing the vaporization of the liquid, and steam will be generated at the outlet.

[0025] The second stainless steel tube 23 and the first stainless steel tube 12 are installed in combination with each other. The first stainless steel tube 12 wraps the second stainless steel tube 23 to form a double-layer design. The micro-metering pump can achieve stable vaporization of liquid feed at a minimum of 0.001 ml / min. A ferrule joint 17 is installed at the end of the second stainless steel tube 23 for fixing the second stainless steel tube 23. At the same time, the flow rate range can be adjusted to a relatively large range, and the maximum liquid vaporization rate can be adjusted to 1 ml / min. Its characteristic is that the surface tension of the liquid is destroyed, so that the liquid is dispersed into a liquid film with a thickness of microns inside the structure, thereby increasing the evaporation surface area.

[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
