Specific embodiment：
To make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With novel range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid unnecessarily mixing
Confuse the concept of the utility model.
Here, it should also be noted that, in order to avoid having obscured the utility model because of unnecessary details, in the accompanying drawings
It illustrate only the structure and/or processing step closely related with scheme according to the present utility model, and be omitted practical with this
The little other details of new relationship.
As shown in Figure 1, present embodiment uses following technical scheme：It include water tank 1, sealing cover 2, exhaust valve 3,
Force (forcing) pump 4, pressure gauge 5, digital display type thermometer 6, PTC heated at constant temperature piece 7, draining rack 8, draining net 9, hot-air blower 10；Water
The upper right side of case 1 is provided with detection opening, and detection opening is convenient for being put into the LED lamp for needing to detect in the water of water tank 1
It all impregnates, sealing cover 2 is installed in detection opening, after LED lamp is put into, the inside of water tank is realized by sealing cover 2, it is close
Exhaust valve 3 is installed, exhaust valve 3 is to complete to be exhausted in detection, and the left side of water tank 1 is separately installed with force (forcing) pump in capping 2
4, pressure gauge 5, digital display type thermometer 6 realize pressurization by force (forcing) pump 4, pressure range 1-4Pa is pressurizeing when detecting
When, pressure gauge 5 can detect pressure value, and PTC heated at constant temperature piece 7 is mounted on the inside of water tank 1, real by PTC heated at constant temperature piece 7
Water heating in existing water tank 1, heating can heat before being put into LED lamp, can also heat in pressurization, according to need
It is selected, and heating temperature is measured by digital display type thermometer 6, and the heated perimeter 10- of PTC heated at constant temperature piece 7
45 DEG C, the principle of PTC heating sheet is self-heating heating after thermistor power-up, and resistance value is made to enter transition area, heated at constant temperature PTC temperature-sensitive
Resistance, surface temperature will be kept；The temperature is only related with the temperature of PTC thermistor and additional voltage, and and environment temperature
It is substantially unrelated；Therefore it can need to connect different voltages, water tank 1 according to temperature when PTC heated at constant temperature piece 7 is heated
Right side wall on draining rack 8 is installed, upon completion of the assays, pass through draining rack 8 realize draining, draining rack 8 interior upside installation
There is draining net 9, draining net 9 is able to achieve the support of LED lamp 11, and the upper end of draining rack 8 is equipped with hot-air blower by bracket
