The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] like Figure 1 As shown, it is a structural schematic diagram of a humidifying device for high-low temperature and humidity alternating test according to a preferred embodiment of the utility model. The humidifying device for high-low temperature and humidity alternating test in this embodiment comprises a heating box 100, and the heating box 100 has a built-in heating device. A water inlet pipe 101 is detachably connected to one side of the heating box 100, and the water inlet pipe 101 is connected to an external water supply. A steam storage box 200 is installed on the upper end of the heating box 100. The water vapor inside the heating box 100 enters the interior of the steam storage box 200. A steam exhaust pipe 202 is detachably connected to one side of the steam storage box 200, and the steam exhaust pipe 202 is connected to the detection chamber. The outer wall of the steam storage box 200 is detachably connected to a delivery air pump 201. In this embodiment, the delivery air pump 201 is used to blow external air into the interior of the steam storage box 200 and carry the steam inside the steam storage box 200 into the detection chamber through the steam exhaust pipe 202. The output power of the delivery air pump 201 is controlled by the data detected by the sensor inside the detection chamber, thereby being able to adjust the precise control of steam humidification.

[0033] like Figure 2 As shown, it is a schematic diagram of the structure of the steam storage box in this embodiment, the steam storage box 200 is fixedly connected with support legs 204 at the four corners of the bottom, the support legs 204 are detachably connected to the upper end of the heating box 100, and the bottom of the steam storage box 200 is detachably connected with a first connecting pipe 205 which is connected to the heating box 100, and the first connecting pipe 205 is detachably connected with a first solenoid valve 206. In this embodiment, the first solenoid valve 206 is closed after starting the delivery air pump 201 to prevent the wind blown by the delivery air pump 201 from entering the interior of the heating box 100, causing water that has not yet evaporated to enter the interior of the detection chamber from the steam discharge pipe 202.

[0034] like Figure 2As shown, in order to prevent the steam from leaking outward when the delivery air pump 201 is closed, in this embodiment, an air intake check valve 203 is installed on the air intake end of the delivery air pump 201 and the steam exhaust pipe 202. The air intake check valve 203 on one side of the delivery air pump 201 opens when the delivery air pump 201 starts to suck air inward, and the air intake check valve 203 on the steam exhaust pipe 202 opens when the steam is discharged outward. In this embodiment, the setting of the air intake check valve 203 can prevent the steam gathered inside the steam storage box 200 from leaking outward, so that the steam can be utilized to the maximum extent to avoid waste, and it can also ensure that the humidity of the environment in which the humidification device is located will not rise.

The upper end of the steam storage box 200 is detachably connected with a pressure sensor 207. In this embodiment, the pressure sensor 207 can detect the pressure inside the steam storage box 200 and the heating box 100. After the pressure reaches the threshold, the heating device inside the heating box 100 is turned off, so that the internal temperature is slowly reduced to avoid damage to the equipment due to excessive pressure.

[0036] like Figure 3 As shown, in order to detect the flow of steam into the detection chamber, in this embodiment, a gas flow meter 208 is detachably connected to the steam exhaust pipe 202. In this embodiment, the steam delivered to the detection chamber can be measured through the setting of the gas flow meter 208, so as to accurately control the relationship between the speed of humidity increase inside the detection chamber and the flow rate, and thus the humidity inside the detection chamber can be more accurately controlled.

[0037] like Figure 4 As shown, it is a schematic diagram of the condensation box structure in this embodiment, a condensation box 300 is installed on the upper end of the heating box 100, and the same support legs 204 are detachably connected at the four corners of the bottom of the condensation box 300, and a second connecting pipe 306 connected to the heating box 100 is detachably connected at the bottom of the condensation box 300, and a second solenoid valve 302 is installed on the second connecting pipe 306. A plurality of staggered through grooves 301 are arranged on both sides of the condensation box 300, and an exhaust pipe is installed on the outer wall of the condensation box 300 near the top, and the outer wall of the condensation box 300 near the bottom is detachably connected. There is a drain pipe 303, and a control valve 304 is installed on the drain pipe 303. In this embodiment, when the internal pressure of the heating box 100 and the steam storage box 200 increases, the second solenoid valve 302 is opened to allow the steam to enter the interior of the condensation box 300 and be discharged outward from the exhaust pipe. The steam can be condensed into water by setting a plurality of through grooves 301. Finally, the condensed water is discharged outward from the drain pipe 303 by opening the control valve 304, thereby avoiding water waste and quickly reducing the internal pressure of the heating box 100 and the steam storage box 200.

[0038] like Figure 4 As shown, in order to make the steam form condensed water faster, in this embodiment, the outer wall of the condensation box 300 is detachably connected with a blower 305. In this embodiment, by starting the blower 305, the speed of air passing through the through groove 301 is increased, thereby accelerating the cooling of the steam and further reducing the waste of water caused by the outward diffusion of steam.
